The term \"Polycystic Ovary Syndrome\" can be misleading, prompting many within the medical community and advocacy groups to advocate for a name change. Critics argue that this terminology can complicate understanding and awareness of the disease among patients. The primary concern is that PCOS emphasizes the ovarian aspect, fostering the misconception that PCOS is merely a gynecological disorder. In reality, PCOS impacts multiple organ systems, particularly metabolic health. Patients frequently experience insulin resistance, weight gain, irregular menstrual cycles, and hirsutism-symptoms that extend beyond ovarian dysfunction. In light of these issues, there is increasing support for renaming PCOS to better reflect its systemic implications and minimize confusion. The current name may hinder understanding and potentially lead to inadequate disease management. Alternative names have been proposed, including \"Ovarian Dysmetabolic Syndrome,\" which our team supports, as well as \"Metabolic Reproductive Syndrome\" and \"Hyperandrogenic Persistent Ovulatory Dysfunction Syndrome.\" These alternatives aim to highlight the hormonal imbalances and metabolic disturbances associated with the condition, fostering inclusivity and reducing stigma for all affected individuals.

Furthermore, the contributions of TCF7L2 to ERK/MAPK signaling and glucose metabolism were investigated in a β-cell-specific TCF7L2 deletion mice model (TCF7L2^β-/-).</p><p><strong>Results: </strong>The results demonstrated that impaired TCF7L2 induces β-cell dedifferentiation and decreases insulin secretion of MIN6 cells via ERK/MAPK signaling pathway. Consistently, decreased pancreatic TCF7L2 protein in parallel with reduced functional β-cells were observed in <i>db</i>/<i>db</i> mice after weeks of normal or high-fat diet. However, the differences between were only significant when the mice were fed to 12 weeks of age. After weeks of high-fat diet feeding, impaired glucose tolerance and increased activation of ERK/MAPK signaling were simultaneously observed in TCF7L2^β-/- mice.</p><p><strong>Conclusion: </strong>The study indicate that the induction of β-cell dedifferentiation mediated by ERK/MAPK signaling pathway might be an essential component of TCF7L2 variants in the development of diabetes.</p>","PeriodicalId":44715,"journal":{"name":"Clinical Medicine Insights-Endocrinology and Diabetes","volume":"17 ","pages":"11795514241295620"},"PeriodicalIF":2.7,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11520015/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142548179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
