Objective: This work aimed to investigate the function and molecular mechanism of circ_0070203 in high-grade serous ovarian cystadenocarcinoma (HGSOC). Methods: circRNA microarray was conducted to detect the circ_0070203 expression in HGSOC tissues. Bioinformatics analysis was used to find the binding sites between circ_0070203, miR- 370-3p and TGFβR2. Real-time quantitative reverse transcription PCR (RT-qPCR) was executed to detect the expressions of circ_0070203, miR-370-3p and TGFβR2 in HGSOC tissues and SKOV3 cells. Dual-luciferase reporter gene assay was used to validate the relationships between miR-370-3p and circ_0070203 or TGFβR2. Besides, transwell assays were conducted to assess the migrative, invasive abilities of ovarian cancer (OC) cells. Western blotting was adopted to detect the expression of epithelial-mesenchymal transition (EMT)-related proteins. The related patents were also studied during the research. Results: Circ_0070203 and TGFβR2 were upregulated, while miR-370-3p was downregulated in FIGO stage Ⅲ-Ⅳ HGSOC tissues and SKOV-3 cell lines. circ_0070203 overexpression changed the expression of other EMT-related proteins and enhanced the migrative, invasive abilities of OC cells, while silencing circ_0070203 worked oppositely. Mechanistically, circ_0070203 could upregulate TGFβR2 expression in OC cells via sponging miR-370-3p. Conclusion: Circ_0070203 could promote the epithelial-mesenchymal transition, invasion, and metastasis of HGSOC via regulating the miR-370-3p/TGFβR2 axis. Our findings provided a potential biomarker for HGSOC therapy.","PeriodicalId":20774,"journal":{"name":"Recent patents on anti-cancer drug discovery","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138525243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The benefit played by this hormone on cancer is due to its antioxidant effects.Objective: This study aimed to evaluate the preclinical effects of melatonin in mice with the Ehrlich ascites tumor.Methods: Twenty Balb/ c male mice with Ehrlich tumor were treated with different melatonin doses. Their inflammatory and oxidative stress were accessed by gene expression. Hepatotoxicity and hematological parameters were also evaluated through biochemical analyses. Animal welfare was analysed weekly from the categories guided by the NC3Rs.Results: Gene expression analyses have shown that only Tnfα and Sod1 were expressed in all groups studied. Only the M-3 group showed increased Tnfα expression compared to the control. All groups treated with melatonin showed decreased Sod1 expression compared to the control. No signs of hepatotoxicity were caused by any of the melatonin doses used in the treatment.Conclusion: In animals with Ehrlich´s tumor treated with melatonin, a decrease in oxidative stress, an amelioration in welfare and in cognitive tasks could be observed, even if the treatment has not reduced the size of the tumor itself. In parallel with the already patented use of melatonin in the treatment of sleep disorders or chronic kidney disease, our results propose its use to improve the general well-being of breast cancer patients.","PeriodicalId":20774,"journal":{"name":"Recent patents on anti-cancer drug discovery","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10775223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinical irradiation of tumors necessitates an understanding of the potential efficacy of radiation protective agents in reducing radiation damage to healthy tissues and their effects on tumor tissue radiosensitivity. Ferroptosis is a relatively new form of iron-dependent cell death that has been linked to a variety of disease pathologies. The key mediators of ferroptosis have been identified as lipid peroxidation and iron metabolism. Lipid peroxidation is the result of a reaction between reactive oxygen (ROS) and reactive nitrogen species (RNS) with phosphatidylethanolamine-containing polyunsaturated fatty acids (PUFAs). Ferroptosis inhibitors have been demonstrated to have anti-inflammatory effects in animal models of disease. It was recently shown that ionizing radiation (IR) generates severe ferroptosis, a critical component of RT-mediated normal cell toxicity. These findings support the use of ferroptosis inhibitor treatments for the treatment of radiation normal cell toxicity. Targeting lipid metabolic substrates and controlling ferroptosis by radiation could reduce toxicity and improve clinical outcomes. In this study, we address the relationships between radiotherapy and various types of radiation-induced cell death, and we discuss the interactions between ferroptosis and other kinds of controlled cell death generated by radiotherapy, and we investigate combination treatment options targeting ferroptosis in radiotherapy. This review will be a foundation for future research on ferroptosis in radiotherapy. Additionally, the relevant patents on ferroptosis inhibitors with various therapeutic potentials have been discussed.\u0000","PeriodicalId":20774,"journal":{"name":"Recent patents on anti-cancer drug discovery","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49145502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that a combinatorial approach of menadione (MEN) as an indirect HIF-1α inhibitor and sodium oxamate (OX) as a glycolysis inhibitor may be a promising treatment strategy for colon cancer.Objectives: We investigated the potential efficacy of this combination for promoting an antitumor immune response and suppressing tumor growth in a rat model of colon cancer.Methods: Colon cancer was induced by once-weekly subcutaneous injection of 20 mg/kg dimethylhydrazine (DMH) for 16 weeks. Control rats received the vehicle and then no further treatment (negative control) or MEN plus OX for 4 weeks (drug control). Dimethylhydrazine-treated rats were then randomly allocated to four groups: DMH alone group and other groups treated with MEN, OX, and a combination of (MEN and OX) for 4 weeks. Serum samples were assayed for the tumor marker carbohydrate antigen (CA19.9), while expression levels of HIF-1α, caspase-3, PHD3, LDH, and PD1 were evaluated in colon tissue samples by immunoassay and qRT-PCR. Additionally, Ki-67 and Siah2 expression levels were examined by immunohistochemistry.Results: The combination of MEN plus OX demonstrated a greater inhibitory effect on the expression levels of HIF-1α, Siah2, LDH, Ki-67, and PD1, and greater enhancement of caspase-3 and PHD3 expression in colon cancer tissues than either drug alone.Conclusion: Simultaneous targeting of hypoxia and glycolysis pathways by a combination of MEN and OX could be a promising therapy for inhibiting colon cancer cell growth and promoting antitumor immunity [1].","PeriodicalId":20774,"journal":{"name":"Recent patents on anti-cancer drug discovery","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10595679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recently published patent applications and forthcoming clinical data of FASN inhibitors from both academia and the pharma industries are also highlighted in this study.Expert opinion: The implication of FASN in multiple diseases has provided an impetus for developing novel inhibitors by both pharma companies and academia. Critical analysis of the patent literature reveals the exploration of diverse molecular scaffolds to identify potential FASN inhibitors that target the different catalytic domains of the enzyme. In spite of these multifaceted efforts, only one molecule, TVB-2640, has reached phase II trials for nonalcoholic steatohepatitis (NASH) and many malignancies. However, thecombined efforts of pharma companies to produce several FASN inhibitors might facilitate the clinical translation of this unique class of inhibitors. Nevertheless, concerted efforts towards developing multiple FASN inhibitors by pharma companies might facilitate the clinical translation of this novel class of inhibitors.","PeriodicalId":20774,"journal":{"name":"Recent patents on anti-cancer drug discovery","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9095387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
