Öğe Advances in understanding the role of P-gp in doxorubicin resistance: molecular pathways, therapeutic strategies, and prospects(Elsevier, 2022) Mirzaei, Sepideh; Gholami, Mohammad Hossein; Hashemi, Farid; Zabolian, Amirhossein; Zarrabi, AliP-glycoprotein (P-gp) is a drug efflux transporter that triggers doxorubicin (DOX) resistance. In this review, we highlight the molecular avenues regulating P-gp, such as Nrf2, HIF-1?, miRNAs, and long noncoding (lnc)RNAs, to reveal their participation in DOX resistance. These antitumor compounds and genetic tools synergistically reduce P-gp expression. Furthermore, ATP depletion impairs P-gp activity to enhance the antitumor activity of DOX. Nanoarchitectures, including liposomes, micelles, polymeric nanoparticles (NPs), and solid lipid nanocarriers, have been developed for the co-delivery of DOX with anticancer compounds and genes enhancing DOX cytotoxicity. Surface modification of nanocarriers, for instance with hyaluronic acid (HA), can promote selectivity toward cancer cells. We discuss these aspects with a focus on P-gp expression and activity. © 2021 The Author(s)Öğe Cervical cancer progression is regulated by SOX transcription factors: Revealing signaling networks and therapeutic strategies(Elsevier Science, 2021) Paskeh, Mahshid Deldar Abad; Mirzaei, Sepideh; Gholami, Mohammad Hossein; Zarrabi, Ali; Zabolian, Amirhossein; Hashemi, Mehrdad; Hushmandi, KiavashCervical cancer is the fourth common gynecologic cancer and is considered as second leading cause of death among women. Various strategies are applied in treatment of cervical cancer including radiotherapy, chemotherapy and surgery. However, cervical cancer cells demonstrate aggressive behavior in advanced phases, requiring novel strategies in their elimination. On the other hand, SOX proteins are transcription factors capable of regulating different molecular pathways and their expression varies during embryogenesis, disease development and carcinogenesis. In the present review, our aim is to reveal role of SOX transcription factors in cervical cancer. SOX transcription factors play like a double-edged sword in cancer. For instance, SOX9 possesses both tumor-suppressor and tumor-promoting role in cervical cancer. Therefore, exact role of each SOX members in cervical cancer has been discussed to direct further experiments for revealing other functions. SOX proteins can regulate proliferation and metastasis of cervical cancer cells. Furthermore, response of cervical cancer cells to chemotherapy and radiotherapy is tightly regulated by SOX transcription factors. Different downstream targets of SOX proteins such as Wnt signaling, EMT and Hedgehog have been identified. Besides, upstream mediators such as microRNAs, lncRNAs and circRNAs can regulate SOX expression in cervical cancer. In addition to pre-clinical studies, role of SOX transcription factors as prognostic and diagnostic tools in cervical cancer has been shown.Öğe Chitosan-based nanoscale systems for doxorubicin delivery: Exploring biomedical application in cancer therapy(AICHE Online Library, 2022) Ashrafizadeh, Milad; Hushmandi, Kiavash; Mirzaei, Sepideh; Bokaie, Saied; Bigham, Ashkan; Makvandi, Pooyan; Rabiee, Navid; Thakur, Vijay Kumar; Kumar, Alan Prem; Sharifi, Esmaeel; Varma, Rajender S.; Aref, Amir Reza; Wojnilowicz, Marcin; Zarrabi, Ali; Karimi-Maleh, Hassan; Voelcker, Nicolas H.; Mostafavi, Ebrahim; Orive, GorkaGreen chemistry has been a growing multidisciplinary field in recent years showing great promise in biomedical applications, especially for cancer therapy. Chitosan (CS) is an abundant biopolymer derived from chitin and is present in insects and fungi. This polysaccharide has favorable characteristics, including biocompatibility, biodegradability, and ease of modification by enzymes and chemicals. CS-based nanoparticles (CS-NPs) have shown potential in the treatment of cancer and other diseases, affording targeted delivery and overcoming drug resistance. The current review emphasizes on the application of CS-NPs for the delivery of a chemotherapeutic agent, doxorubicin (DOX), in cancer therapy as they promote internalization of DOX in cancer cells and prevent the activity of P-glycoprotein (P-gp) to reverse drug resistance. These nanoarchitectures can provide co-delivery of DOX with antitumor agents such as curcumin and cisplatin to induce synergistic cancer therapy. Furthermore, co-loading of DOX with siRNA, shRNA, and miRNA can suppress tumor progression and provide chemosensitivity. Various nanostructures, including lipid-, carbon-, polymeric- and metal-based nanoparticles, are modifiable with CS for DOX delivery, while functionalization of CS-NPs with ligands such as hyaluronic acid promotes selectivity toward tumor cells and prevents DOX resistance. The CS-NPs demonstrate high encapsulation efficiency and due to protonation of amine groups of CS, pH-sensitive release of DOX can occur. Furthermore, redox- and light-responsive CS-NPs have been prepared for DOX delivery in cancer treatment. Leveraging these characteristics and in view of the biocompatibility of CS-NPs, we expect to soon see significant progress towards clinical translation.Öğe Correction: The long and short non-coding RNAs modulating EZH2 signaling in cancer (Journal of Hematology & Oncology, (2022), 15, 1, (18), 10.1186/s13045-022-01235-1)(BioMed Central Ltd, 2022) Mirzaei, Sepideh; Gholami, Mohammad Hossein; Hushmandi, Kiavash; Hashemi, Farid; Zabolian, Amirhossein; Canadas, Israel; Zarrabi, Ali; Nabavi, Noushin; Aref, Amir Reza; Crea, Francesco; Wang, Yuzhuo; Ashrafizadeh, Milad; Kumar, Alan PremThe original article [1] contained an error in co-author, Farid Hashemi’s name which has since been corrected. © 2022, The Author(s).Öğe Curcumin and its derivatives in cancer therapy: potentiating antitumor activity of cisplatin and reducing side effects(WILEY, 2021) Abadi, Asal Jalal; Mirzaei, Sepideh; Mahabady, Mahmood Khaksary; Hashemi, Farid; Zabolian, Amirhossein; Hashemi, Fardin; Raee, Pourya; Zarrabi, AliCurcumin is a phytochemical isolated from Curcuma longa with potent tumor-suppressor activity, which has shown significant efficacy in pre-clinical and clinical studies. Curcumin stimulates cell death, triggers cycle arrest, and suppresses oncogenic pathways, thereby suppressing cancer progression. Cisplatin (CP) stimulates DNA damage and apoptosis in cancer chemotherapy. However, CP has adverse effects on several organs of the body, and drug resistance is frequently observed. The purpose of the present review is to show the function of curcumin in decreasing CP's adverse impacts and improving its antitumor activity. Curcumin administration reduces ROS levels to prevent apoptosis in normal cells. Furthermore, curcumin can inhibit inflammation via down-regulation of NF-kappa B to maintain the normal function of organs. Curcumin and its nanoformulations can reduce the hepatoxicity, neurotoxicity, renal toxicity, ototoxicity, and cardiotoxicity caused by CP. Notably, curcumin potentiates CP cytotoxicity via mediating cell death and cycle arrest. Besides, curcumin suppresses the STAT3 and NF-kappa B as tumor-promoting pathways, to enhance CP sensitivity and prevent drug resistance. The targeted delivery of curcumin and CP to tumor cells can be mediated nanostructures. In addition, curcumin derivatives are also able to reduce CP-mediated side effects, and increase CP cytotoxicity against various cancer types.Öğe Development of lateral flow assays for rapid detection of troponin ı: a review(TAYLOR & FRANCIS INC, 2022) Mohammadinejad, Arash; Nooranian, Samin; Oskuee, Reza Kazemi; Mirzaei, Sepideh; Aleyaghoob, Ghazaleh; Zarrabi, AliTroponin I as a particular and major biomarker of cardiac failure is released to blood demonstrating hurt of myocardial cells. Unfortunately, troponin I detection in the first hours of acute myocardial infarction usually faces with most negligence. Therefore, developments of point of care devices such as lateral flow strips are highly required for timely diagnosis and prognosis. Lateral flow assays are low-cost paper-based detection platforms relying on specific diagnostic agents such as aptamers and antibodies for a rapid, selective, quantitative and semi-quantitative detection of the analyte in a complex mixture. Moreover, lateral flow assay devices are portable, and their simplicity of use eliminates the need for experts or any complicated equipment to operate and interpret the test results. Additionally, by coupling the lateral flow assay technology with nanotechnology, for labeling and signal amplification, many breakthroughs in the field of diagnostics have been achieved. The present study reviews the use of lateral flow assays in early stage, quantitative, and sensitive detection of cardiac troponin I and mainly focuses on the structure of each type of developed lateral flow assays. Finally, this review summarized the improvements, detection time, and limit of detection of each study as well as the advantages and disadvantages.Öğe Emerging role of exosomes in cancer progression and tumor microenvironment remodeling(BioMed Central, 2022) Paskeh, Mahshid Deldar Abad; Entezari, Maliheh; Mirzaei, Sepideh; Zabolian, Amirhossein; Zarrabi, AliCancer is one of the leading causes of death worldwide, and the factors responsible for its progression need to be elucidated. Exosomes are structures with an average size of 100 nm that can transport proteins, lipids, and nucleic acids. This review focuses on the role of exosomes in cancer progression and therapy. We discuss how exosomes are able to modulate components of the tumor microenvironment and influence proliferation and migration rates of cancer cells. We also highlight that, depending on their cargo, exosomes can suppress or promote tumor cell progression and can enhance or reduce cancer cell response to radio- and chemo-therapies. In addition, we describe how exosomes can trigger chronic inflammation and lead to immune evasion and tumor progression by focusing on their ability to transfer non-coding RNAs between cells and modulate other molecular signaling pathways such as PTEN and PI3K/Akt in cancer. Subsequently, we discuss the use of exosomes as carriers of anti-tumor agents and genetic tools to control cancer progression. We then discuss the role of tumor-derived exosomes in carcinogenesis. Finally, we devote a section to the study of exosomes as diagnostic and prognostic tools in clinical courses that is important for the treatment of cancer patients. This review provides a comprehensive understanding of the role of exosomes in cancer therapy, focusing on their therapeutic value in cancer progression and remodeling of the tumor microenvironment. Graphical Abstract: [Figure not available: see fulltext.]. © 2022, The Author(s).Öğe Exosome-mediated miR-200a delivery into TGF-?-treated AGS cells abolished epithelial-mesenchymal transition with normalization of ZEB1, vimentin and Snail1 expression(Academic Press Inc Elsevier Science, 2023) Mirzaei, Sepideh; Gholami, Mohammad Hossein; Aghdaei, Hamid Asadzadeh; Hashemi, Mehrdad; Parivar, Kazem; Karamian, Amin; Zarrabi, AliExosomes are small extracellular vesicles that can be derived from human cells such as mesenchymal stem cells (MSCs). The size of exosomes is at nano-scale range and owing to their biocompatibility and other characteristics, they have been promising candidates for delivery of bioactive compounds and genetic materials in disease therapy, especially cancer therapy. Gastric cancer (GC) is a leading cause of death among patients and this malignant disease affects gastrointestinal tract that its invasiveness and abnormal migration mediate poor prognosis of patients. Metastasis is an increasing challenge in GC and microRNAs (miRNAs) are potential reg-ulators of metastasis and related molecular pathways, especially epithelial-to-mesenchymal transition (EMT). In the present study, our aim was to explore role of exosomes in miR-200a delivery for suppressing EMT-mediated GC metastasis. Exosomes were isolated from MSCs via size exclusion chromatography. The synthetic miR-200a mimics were transfected into exosomes via electroporation. AGS cell line exposed to TGF-beta for EMT induction and then, these cells cultured with miR-200a-loaded exosomes. The transwell assays performed to evaluate GC migration and expression levels of ZEB1, Snail1 and vimentin measured. Exosomes demonstrated loading effi-ciency of 5.92 +/- 4.6%. The TGF-beta treatment transformed AGS cells into fibroblast-like cells expressing two stemness markers, CD44 (45.28%) and CD133 (50.79%) and stimulated EMT. Exosomes induced a 14.89-fold increase in miR-200a expression in AGS cells. Mechanistically, miR-200a enhances E-cadherin levels (P < 0.01), while it decreases expression levels of beta-catenin (P < 0.05), vimentin (P < 0.01), ZEB1 (P < 0.0001) and Snail1 (P < 0.01), leading to EMT inhibition in GC cells. This pre-clinical experiment introduces a new strategy for miR-200a delivery that is of importance for preventing migration and invasion of GC cells.Öğe The long and short non-coding RNAs modulating EZH2 signaling in cancer(2022) Mirzaei, Sepideh; Gholami, Mohammad Hossein; Hushmandi, Kiavash; Hshemi, Farid; Zabolian, Amirhossein; Canadas, Israel; Zarrabi, Ali; Nabavi, Noushin; Aref, Amir Reza; Crea, Francesco; Wang, Yuzhuo; Ashrafizadeh, Milad; Kumar, Alan PremNon-coding RNAs (ncRNAs) are a large family of RNA molecules with no capability in encoding proteins. However, they participate in developmental and biological processes and their abnormal expression affects cancer progression. These RNA molecules can function as upstream mediators of different signaling pathways and enhancer of zeste homolog 2 (EZH2) is among them. Briefly, EZH2 belongs to PRCs family and can exert functional roles in cells due to its methyltransferase activity. EZH2 affects gene expression via inducing H3K27me3. In the present review, our aim is to provide a mechanistic discussion of ncRNAs role in regulating EZH2 expression in different cancers. MiRNAs can dually induce/inhibit EZH2 in cancer cells to affect downstream targets such as Wnt, STAT3 and EMT. Furthermore, miRNAs can regulate therapy response of cancer cells via affecting EZH2 signaling. It is noteworthy that EZH2 can reduce miRNA expression by binding to promoter and exerting its methyltransferase activity. Small-interfering RNA (siRNA) and short-hairpin RNA (shRNA) are synthetic, short ncRNAs capable of reducing EZH2 expression and suppressing cancer progression. LncRNAs mainly regulate EZH2 expression via targeting miRNAs. Furthermore, lncRNAs induce EZH2 by modulating miRNA expression. Circular RNAs (CircRNAs), like lncRNAs, affect EZH2 expression via targeting miRNAs. These areas are discussed in the present review with a focus on molecular pathways leading to clinical translation.Öğe Molecular landscape of LncRNAs in prostate cancer: A focus on pathways and therapeutic targets for intervention(PMC, 2022) Mirzaei, Sepideh; Abad Paskeh, Mahshid Deldar; Okina, Elena; Gholami, Mohammad Hossein; Hushmandi, Kiavash; Hashemi, Mehrdad; Kalu , Azuma; Zarrabi, Ali; Nabav, Noushin; Rabiee, Navid; Sharifi, Esmaeel; Karimi-Maleh, Hassan; Ashrafizadeh, Milad; Kumar, Alan Prem; Wang, YuzhuoBackground: One of the most malignant tumors in men is prostate cancer that is still incurable due to its heterog? enous and progressive natures. Genetic and epigenetic changes play signifcant roles in its development. The RNA molecules with more than 200 nucleotides in length are known as lncRNAs and these epigenetic factors do not encode protein. They regulate gene expression at transcriptional, post-transcriptional and epigenetic levels. LncRNAs play vital biological functions in cells and in pathological events, hence their expression undergoes dysregulation. Aim of review: The role of epigenetic alterations in prostate cancer development are emphasized here. Therefore, lncRNAs were chosen for this purpose and their expression level and interaction with other signaling networks in prostate cancer progression were examined. Key scientifc concepts of review: The aberrant expression of lncRNAs in prostate cancer has been well-docu? mented and progression rate of tumor cells are regulated via afecting STAT3, NF-?B, Wnt, PI3K/Akt and PTEN, among other molecular pathways. Furthermore, lncRNAs regulate radio-resistance and chemo-resistance features of prostate tumor cells. Overexpression of tumor-promoting lncRNAs such as HOXD-AS1 and CCAT1 can result in drug resistance. Besides, lncRNAs can induce immune evasion of prostate cancer via upregulating PD-1. Pharmacological compounds such as quercetin and curcumin have been applied for targeting lncRNAs. Furthermore, siRNA tool can reduce expression of lncRNAs thereby suppressing prostate cancer progression. Prognosis and diagnosis of prostate tumor at clinical course can be evaluated by lncRNAs. The expression level of exosomal lncRNAs such as lncRNA-p21 can be investigated in serum of prostate cancer patients as a reliable biomarkerÖğe (Nano)platforms in bladder cancer therapy: Challenges and opportunities(John Wiley and Sons Inc, 2022) Ashrafizadeh, Milad; Zarrabi, Ali; Karimi-Maleh, Hassan; Taheriazam, Afshin; Mirzaei, SepidehUrological cancers are among the most common malignancies around the world. In particular, bladder cancer severely threatens human health due to its aggressive and heterogeneous nature. Various therapeutic modalities have been considered for the treatment of bladder cancer although its prognosis remains unfavorable. It is perceived that treatment of bladder cancer depends on an interdisciplinary approach combining biology and engineering. The nanotechnological approaches have been introduced in the treatment of various cancers, especially bladder cancer. The current review aims to emphasize and highlight possible applications of nanomedicine in eradication of bladder tumor. Nanoparticles can improve efficacy of drugs in bladder cancer therapy through elevating their bioavailability. The potential of genetic tools such as siRNA and miRNA in gene expression regulation can be boosted using nanostructures by facilitating their internalization and accumulation at tumor sites and cells. Nanoparticles can provide photodynamic and photothermal therapy for ROS overgeneration and hyperthermia, respectively, in the suppression of bladder cancer. Furthermore, remodeling of tumor microenvironment and infiltration of immune cells for the purpose of immunotherapy are achieved through cargo-loaded nanocarriers. Nanocarriers are mainly internalized in bladder tumor cells by endocytosis, and proper design of smart nanoparticles such as pH-, redox-, and light-responsive nanocarriers is of importance for targeted tumor therapy. Bladder cancer biomarkers can be detected using nanoparticles for timely diagnosis of patients. Based on their accumulation at the tumor site, they can be employed for tumor imaging. The clinical translation and challenges are also covered in current review. © 2022 The Authors.

Although treatment modalities including surgery, chemotherapy, and radiotherapy are utilized for breast cancer, it is still a life-threatening disease for humans. Nanomedicine has provided a new opportunity in breast cancer treatment, which is the focus of the current study. The nanocarriers deliver chemotherapeutic agents and natural products, both of which increase cytotoxicity against breast tumor cells and prevent the development of drug resistance. The efficacy of gene therapy is boosted by nanoparticles and the delivery of CRISPR/Cas9, Noncoding RNAs, and RNAi, promoting their potential for gene expression regulation. The drug and gene codelivery by nanoparticles can exert a synergistic impact on breast tumors and enhance cellular uptake via endocytosis. Nanostructures are able to induce photothermal and photodynamic therapy for breast tumor ablation via cell death induction. The nanoparticles can provide tumor microenvironment remodeling and repolarization of macrophages for antitumor immunity. The stimuli-responsive nanocarriers, including pH-, redox-, and light-sensitive, can mediate targeted suppression of breast tumors. Besides, nanoparticles can provide a diagnosis of breast cancer and detect biomarkers. Various kinds of nanoparticles have been employed for breast cancer therapy, including carbon-, lipid-, polymeric- and metal-based nanostructures, which are different in terms of biocompatibility and delivery efficiency.Öğe Nanoliposomes as nonviral vectors in cancer gene therapy(John Wiley and Sons Inc, 2024) Yıldız, Safiye Nur; Entezari, Maliheh; Paskeh, Mahshid Deldar Abad; Mirzaei, Sepideh; Kalbasi, Alireza; Zabolian, Amirhossein; Hashemi, Farid; Hushmandi, Kiavash; Hashemi, Mehrdad; Raei, Mehdi; Goharrizi, Mohammad Ali Sheikh Beig; Aref, Amir Reza; Zarrabi, Ali; Ren, Jun; Orive, Gorka; Rabiee, Navid; Ertaş, Yavuz NuriNonviral vectors, such as liposomes, offer potential for targeted gene delivery in cancer therapy. Liposomes, composed of phospholipid vesicles, have demonstrated efficacy as nanocarriers for genetic tools, addressing the limitations of off-targeting and degradation commonly associated with traditional gene therapy approaches. Due to their biocompatibility, stability, and tunable physicochemical properties, they offer potential in overcoming the challenges associated with gene therapy, such as low transfection efficiency and poor stability in biological fluids. Despite these advancements, there remains a gap in understanding the optimal utilization of nanoliposomes for enhanced gene delivery in cancer treatment. This review delves into the present state of nanoliposomes as carriers for genetic tools in cancer therapy, sheds light on their potential to safeguard genetic payloads and facilitate cell internalization alongside the evolution of smart nanocarriers for targeted delivery. The challenges linked to their biocompatibility and the factors that restrict their effectiveness in gene delivery are also discussed along with exploring the potential of nanoliposomes in cancer gene therapy strategies by analyzing recent advancements and offering future directions. © 2024 The Author(s).

On the other hand, non-coding RNAs (ncRNAs) can modulate macrophage polarization in TME to affect cancer progression. The miRNAs can dually induce/suppress M2 polarization of macrophages and by affecting various molecular pathways, they modulate tumor progression and therapy response. The lncRNAs can affect miRNAs via sponging and other molecular pathways to modulate macrophage polarization. A few experiments have also examined role of circRNAs in targeting signaling networks and affecting macrophages. The therapeutic targeting of these ncRNAs can mediate TME remodeling and affect macrophage polarization. Furthermore, exosomal ncRNAs derived from tumor cells or macrophages can modulate polarization and TME remodeling. Suppressing biogenesis and secretion of exosomes can inhibit ncRNA-mediated M2 polarization of macrophages and prevent tumor progression. The ncRNAs, especially exosomal ncRNAs can be considered as non-invasive biomarkers for tumor diagnosis. © 2022 Elsevier B.V.Öğe Noncoding RNAs and their therapeutics in paclitaxel chemotherapy: Mechanisms of initiation, progression, and drug sensitivity(Wiley, 2022) Mahabady, Mahmood K.; Mirzaei, Sepideh; Saebfar, Hamidreza; Gholami, Mohammad H.; Zabolian, Amirhossein; Hushmandi, Kiavash; Hashemi, Farid; Tajik, Fatemeh; Hashemi, Mehrdad; Kumar, Alan P.; Aref, Amir R.; Zarrabi, Ali; Khan, Haroon; Hamblin, Michael R.; Ertas, Yavuz Nuri; Samarghandian, SaeedThe identification of agents that can reverse drug resistance in cancer chemotherapy, andenhance the overall efficacy is of great interest. Paclitaxel (PTX) belongs to taxane family hat exerts an antitumor effect by stabilizing microtubules and inhibiting cell cycleprogression. However, PTX resistance often develops in tumors due to the over-expression of drug transporters and tumor?promoting pathways. Noncoding RNAs(ncRNAs) are modulators of many processes in cancer cells, such as apoptosis, migration,differentiation, and angiogenesis. In the present study, we summarize the effects ofncRNAs on PTX chemotherapy. MicroRNAs (miRNAs) can have opposite effects on PTXresistance (stimulation or inhibition) via influencing YES1, SK2, MRP1, and STAT3.Moreover, miRNAs modulate the growth and migration rates of tumor cells in regulatingPTX efficacy. PIWI?interacting RNAs, small interfering RNAs, and short?hairpin RNAs areother members of ncRNAs regulating PTX sensitivity of cancer cells. Long noncodingRNAs (LncRNAs) are similar to miRNAs and can modulate PTX resistance/sensitivity bytheir influence on miRNAs and drug efflux transport. The cytotoxicity of PTX againsttumor cells can also be affected by circular RNAs (circRNAs) and limitation is thatoncogenic circRNAs have been emphasized and experiments should also focus on onco?suppressor circRNAs.Öğe Resveratrol Augments Doxorubicin and Cisplatin Chemotherapy: A Novel Therapeutic Strategy(Bentham Science Publ Ltd, 2023) Mirzaei, Sepideh; Gholami, Mohammad Hossein; Zabolian, Amirhossein; Saleki, Hossein; Bagherian, Morteza; Torabi, Seyed Mohammadreza; Sharifzadeh, Seyed OmidBackground The treatment of cancer is a current challenge for public health, causing high rates of morbidity and mortality worldwide. Doxorubicin (DOX) and cisplatin (CP) are two well-known chemotherapeutic agents approved by the Food and Drug Administration to treat cancer patients. However, there are two problems associated with DOX and CP: drug resistance and adverse impact. Resveratrol (Res) belongs to the stilbene class and possesses various health-promoting effects, such as antioxidant, anti-inflammatory, anticancer, hepatoprotective, and neuroprotective effects. Objective The present review aims to give special attention to the therapeutic impacts of Res in potentiating DOX and CP's antitumor activities and reducing their side effects. Methods PubMed, Science Direct, and Google Scholar were used to search articles for the current manuscripts. Results Co-administration of Res can prevent chemoresistance and potentiate the induction of apoptosis and cell cycle arrest in cancer cells. Res can enhance the sensitivity of cancer cells to DOX and CP chemotherapy by inhibiting the migration and metastasis of cancer cells. Simultaneously, Res, due to its therapeutic actions ameliorates the adverse impacts of DOX and CP on normal cells and organs, including the liver, kidney, brain, and testes. As Res suffers from poor bioavailability, nanoformulations have been developed with promising results to improve its antitumor activity and protective effects. Conclusion Based on preclinical studies, it is obvious that Res is a promising adjsuvant for CP and DOX chemotherapy, and its benefits can be utilized in the clinical course.Öğe Resveratrol in breast cancer treatment: from cellular effects to molecular mechanisms of action(Springer Science and Business Media Deutschland GmbH, 2022) Behroozaghdam, Mitra; Dehghani, Maryam; Zabolian, Amirhossein; Kamali, Davood; Javanshir, Salar; Hasani Sadi, Farzaneh; Hashemi, Mehrdad; Tabari, Teimour; Rashidi, Mohsen; Mirzaei, Sepideh; Zarepour, Atefeh; Zarrabi, Ali; De Greef, Danielle; Bishayee, AnupamBreast cancer (BC) is one of the most common cancers in females and is responsible for the highest cancer-related deaths following lung cancer. The complex tumor microenvironment and the aggressive behavior, heterogenous nature, high proliferation rate, and ability to resist treatment are the most well-known features of BC. Accordingly, it is critical to find an effective therapeutic agent to overcome these deleterious features of BC. Resveratrol (RES) is a polyphenol and can be found in common foods, such as pistachios, peanuts, bilberries, blueberries, and grapes. It has been used as a therapeutic agent for various diseases, such as diabetes, cardiovascular diseases, inflammation, and cancer. The anticancer mechanisms of RES in regard to breast cancer include the inhibition of cell proliferation, and reduction of cell viability, invasion, and metastasis. In addition, the synergistic effects of RES in combination with other chemotherapeutic agents, such as docetaxel, paclitaxel, cisplatin, and/or doxorubicin may contribute to enhancing the anticancer properties of RES on BC cells. Although, it demonstrates promising therapeutic features, the low water solubility of RES limits its use, suggesting the use of delivery systems to improve its bioavailability. Several types of nano drug delivery systems have therefore been introduced as good candidates for RES delivery. Due to RES’s promising potential as a chemopreventive and chemotherapeutic agent for BC, this review aims to explore the anticancer mechanisms of RES using the most up to date research and addresses the effects of using nanomaterials as delivery systems to improve the anticancer properties of RES.

Following ischemia, reperfusion and reoxygenation may occur which further worsens oxidative stress-mediated damage in cells and tissues. The combined processes are referred to as ischemia/reperfusion (I/R) injury. Immediate management and treatment of I/R is of utmost importance for preventing irreversible and extensive cellular damage. Apoptosis, inflammation and oxidative stress are the most validated pathologies associated with I/R. AMP-activated protein kinase (AMPK) modulates energy metabolism in cells and its activation occurs in response to elevated AMP and ADP levels. Aberrant levels of AMPK are noted in various pathological settings such as diabetes mellitus, cancer and neurological diseases. This review emphasizes AMPK signaling, its related molecular pathways and therapeutic utility during I/R. Activation of AMPK through phosphorylation prevents apoptosis and reduces oxidative stress and inflammation upon I/R. Inducing AMPK signaling normalizes mitochondrial function to inhibit cell death. Autophagy as a cytoprotective mechanism undergoes activation by AMPK/mTOR and AMPK/ULK1 pathways. AMPK reinforces the antioxidant defense capacity via Nrf2 signaling to counteract oxidative stress in I/R. Protective compounds including phytochemicals activate AMPK to alleviate I/R injury.Öğe Targeting autophagy in prostate cancer: preclinical and clinical evidence for therapeutic response(2022) Ashrafizadeh, Milad; Deldar Abad Paskeh, Mahshid; Mirzaei, Sepideh; Gholami, Mohammad Hossein; Zarrabi, AliProstate cancer is a leading cause of death worldwide and new estimates revealed prostate cancer as the leading cause of death in men in 2021. Therefore, new strategies are pertinent in the treatment of this malignant disease. Macroautophagy/autophagy is a "self-degradation" mechanism capable of facilitating the turnover of long-lived and toxic macromolecules and organelles. Recently, attention has been drawn towards the role of autophagy in cancer and how its modulation provides effective cancer therapy. In the present review, we provide a mechanistic discussion of autophagy in prostate cancer. Autophagy can promote/inhibit proliferation and survival of prostate cancer cells. Besides, metastasis of prostate cancer cells is affected (via induction and inhibition) by autophagy. Autophagy can affect the response of prostate cancer cells to therapy such as chemotherapy and radiotherapy, given the close association between autophagy and apoptosis. Increasing evidence has demonstrated that upstream mediators such as AMPK, non-coding RNAs, KLF5, MTOR and others regulate autophagy in prostate cancer. Anti-tumor compounds, for instance phytochemicals, dually inhibit or induce autophagy in prostate cancer therapy. For improving prostate cancer therapy, nanotherapeutics such as chitosan nanoparticles have been developed. With respect to the context-dependent role of autophagy in prostate cancer, genetic tools such as siRNA and CRISPR-Cas9 can be utilized for targeting autophagic genes. Finally, these findings can be translated into preclinical and clinical studies to improve survival and prognosis of prostate cancer patients.Öğe Targeting Nrf2 in ischemia-reperfusion alleviation: From signaling networks to therapeutic targeting(Elsevier Inc., 2022) Sadrkhanloo, Mehrdokht; Entezari, Maliheh; Orouei, Sima; Zabolian, Amirhossein; Mirzaie, Amirreza; Maghsoudloo, Amin; Raesi, Rasoul; Asadi, Neda; Hashemi, Mehrdad; Zarrabi, Ali; Khan, Haroon; Mirzaei, Sepideh; Samarghandian, SaeedThe nuclear factor erythroid 2-related factor 2 (Nrf2) is a master regulator of redox balance and it responds to various cell stresses that oxidative stress is the most well-known one. The Nrf2 should undergo nuclear translocation to exert its protective impacts and decrease ROS production. On the other hand, ischemic/reperfusion (I/R) injury is a pathological event resulting from low blood flow to an organ and followed by reperfusion. The I/R induces cell injury and organ dysfunction. The present review focuses on Nrf2 function in alleviation of I/R injury. Stimulating of Nrf2 signaling ameliorates I/R injury in various organs including lung, liver, brain, testis and heart. The Nrf2 enhances activity of antioxidant enzymes to reduce ROS production and prevent oxidative stress-mediated cell death. Besides, Nrf2 reduces inflammation via decreasing levels of pro-inflammatory factors including IL-6, IL-1? and TNF-?. Nrf2 signaling is beneficial in preventing apoptosis and increasing cell viability. Nrf2 induces autophagy to prevent apoptosis during I/R injury. Furthermore, it can interact with other molecular pathways including PI3K/Akt, NF-?B, miRNAs, lncRNAs and GSK-3? among others, to ameliorate I/R injury. The therapeutic agents, most of them are phytochemicals such as resveratrol, berberine and curcumin, induce Nrf2 signaling in I/R injury alleviation. © 2022
