Mast cells are tissue resident, sentinel immune cells that reside in the pancreas, adipose tissue, and brain, increase in T2D and AD, and have generally been shown to worsen T2D and AD. However, there are limited studies of local or temporal mast cell deletion, and different phenotypic and polarization states seemingly influence the role of mast cells in the progression of disease. As there are metabolic similarities between T2D and AD including insulin resistance and lipid influx into the brain, we discuss the impact of glucose, insulin, amylin, and different lipid species on the activation and polarization of mast cells, which generally reduce IgE-mediated degranulation and promote lipid droplet formation and arachidonic acid metabolism. Altogether, this review provides a framework for understanding a shared mechanism of immunometabolic regulation of T2D and AD and provides rationale for future work in this area.</p></div>","PeriodicalId":15220,"journal":{"name":"Journal of Cellular Physiology","volume":"240 9","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Hippo signaling pathway, modulated by long noncoding RNAs (lncRNAs), is implicated in regulating GCs proliferation and ovarian aging. TEAD2 (Transcriptional Enhanced Associate Domain 2), a key downstream transcription factor of the Hippo signaling pathway, plays a critical role in regulating cell proliferation, apoptosis, and embryonic stem cell self-renewal. However, the precise molecular mechanisms by which lncRNAs influence the Hippo pathway in GCs are not fully understood. Through comprehensive RNA-seq analysis of ovarian tissues across three distinct age groups (3-, 11-, and 17-month-old mice), we identified lnc81 as a senescence-associated lncRNA that physically interacts with TEAD2. RNA immunoprecipitation (RIP) assays demonstrated direct binding between lnc81 and TEAD2, while subcellular fractionation coupled with qRT-PCR revealed predominant nuclear localization of lnc81 in granulosa cells (GCs). Importantly, lnc81 expression exhibited a progressive, age-dependent elevation during ovarian aging. Functional characterization showed that lnc81 knockdown in GCs significantly: (i) Inhibited cellular proliferation (as evidenced by decreased <i>Pcna</i> expression). (ii) Promoted apoptosis (indicated by increased BAX/BCL-2 ratio and elevated TUNEL-positive cells). Mechanistically, while lnc81 depletion upregulated CCN1/CCN2 protein levels, it did not affect TEAD2 expression, suggesting that lnc81 regulates TEAD2 transcriptional activity rather than modulating its protein stability. Our findings highlight lnc81 as a nuclear lncRNA that interacts with TEAD2 to amplify CCN1/CCN2 signaling, thereby promoting GC apoptosis and ovarian aging. This mechanistic insight positions lnc81 as a potential biomarker for age-related ovarian decline and a candidate target for therapeutic intervention.</p></div>","PeriodicalId":15220,"journal":{"name":"Journal of Cellular Physiology","volume":"240 9","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cx43 has recently been identified within the mitochondria of cells, suggesting that it may have additional functions beyond its canonical role. Most studies of mitochondrial Cx43 (mt-Cx43) have been limited to cells of the cardiovascular system, where it appears to play a role in ATP production, calcium homeostasis, and the response to oxidative stress. However, its functions within the central nervous system (CNS) are not fully understood. Recently, it has been observed that Cx43-forming GJs is one of the key mechanisms that cells use for the transfer of organelles, including mitochondria.

The purpose of this study was to explore the role of Grb10 in high glucose-induced H9c2 cardiomyoblast apoptosis and investigate the underlying molecular mechanisms. H9c2 cardiomyoblasts were cultured and exposed to an elevated glucose at a level of 33 mM. Grb10 expression was inhibited using small interfering RNA (siRNA), and the activities of ERK1/2 and STAT3 were stimulated by specific activators. Western blot analysis was used to detect the expression levels of Grb10, (phosphorylated) ERK1/2, (phosphorylated) JAK2/STAT3, Bax, Bcl2, and cleaved caspase-3, and the TdT-mediated UTP nick end labeling test was used to measure the apoptosis rate. High glucose treatment in H9c2 cardiomyoblasts led to increased Grb10 expression and cell apoptosis. Grb10-siRNA treatment attenuated high glucose-induced H9c2 cell apoptosis. Furthermore, the repressed activities of ERK1/2 and JAK2/STAT3 signaling pathways induced by high glucose were reversed by Grb10-siRNA treatment. Upregulated ERK1/2 or STAT3 activity partially reversed the apoptosis of H9c2 cardiomyoblast caused by high glucose treatment.
