Herein noted an age-dependent decrease of hepatic Ubc9 expression is first noted along with an escalated decrease of protein SUMOylation, which is coupled with enhanced senescent marker expressions both in humans and mice. Interestingly, Ubc9 is dispensable for liver development at the embryonic stage. However, Ubc9 deficiency in hepatocytes rendered mice with an exacerbated hepatic aging phenotype and more susceptible to fatty liver disease and steatohepatitis following the challenge of a methionine- and choline-deficient (MCD)-diet. Ii is further demonstrated that nuclear ribosomal protein L3 (RPL3) interacts with DExD/H-box (DDX/DHX) helicases (DHX9), which then recruits RNA polymerase II to the p16 promoter to transcribe its expression, thereby exacerbating the hepatocyte aging process. However, Ubc9-mediated SUMOylation prevents RPL3 nuclear translocation, by which it represses the expression of senescent markers such as p16 to attenuate the hepatic aging process.

However, the mechanisms that control this change and its impact on GC progression remain poorly understood. In this study, it is demonstrated that methyltransferase-like 10 (METTL10) is a key regulator of gastric tumor formation by enhancing purine metabolism in GC cells. It is discovered that METTL10 methylates the protein inhibitor of activated STAT3 (PIAS3) at the lysine 442 (K442) residue, which interferes with the interaction of PIAS3 with microphthalmia-associated transcription factor (MITF). As a result, the sumoylation and ubiquitination of MITF by PIAS3 are reduced, leading to MITF stabilization and activation of purine metabolism. Importantly, both the accumulation of MITF and the methylation of K442 in PIAS3 are required for the oncogenic effects of METTL10, and both factors are closely linked to poor clinical outcomes in GC. Furthermore, this study identified a compound, LZQ-02-023-01, which effectively induces the METTL10-mediated ubiquitination and degradation of MITF, thereby reducing the oncogenic activity of METTL10. The findings suggest that METTL10 plays an important role in reprogramming purine metabolism, which promotes GC, highlighting it as a potential therapeutic target for GC treatment.</p>","PeriodicalId":117,"journal":{"name":"Advanced Science","volume":" ","pages":"e07054"},"PeriodicalIF":14.1,"publicationDate":"2025-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145327927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These observations reveal that circular waves originate nearly simultaneously at the obstacles and propagate outward. In a covered setup, where evaporation is minimal, the wavefronts maintain their circular shape. However, in an uncovered setup with significant evaporation and resulting Marangoni flows, the interplay between surface tension-driven Marangoni flows and gravity destabilizes the wavefronts, creating distinctive flower-like patterns around the obstacles.
