Background/Objective: Diabetes mellitus (DM) remains a major global health challenge due to its chronic nature and associated complications. Traditional diagnostic approaches, though effective, often lack the sensitivity required for early-stage detection. Recent advancements in molecular biology have identified RNA molecules, particularly non-coding RNAs such as microRNAs (miRNAs), long (lncRNAs), circular (circRNAs), promising biomarkers diabetes. This review aims explore role of RNA-based diagnosis, prognosis, management diabetes, highlighting their potential revolutionize diabetes care. Method: A comprehensive literature was conducted using electronic databases including PubMed, Scopus, Web Science. Articles published up 2024 were screened analyzed extract relevant findings related diagnostics Emphasis placed on studies demonstrating clinical utility, mechanistic insights, translational molecules. Results: Numerous species, miRNAs miR-375, miR-29, lncRNAs like H19 MEG3, exhibit altered expression patterns diabetic patients. These molecules are involved key regulatory pathways glucose metabolism, insulin resistance, β-cell function. Circulating detectable various biofluids, enabling non-invasive approaches. Emerging technologies, sequencing liquid biopsy platforms, enhanced specificity detection, fostering development novel tools personalized therapeutic strategies. Conclusion: hold significant promise advancing early risk stratification, monitoring Despite current challenges standardization validation, integration into routine practice could transform management, paving way precision medicine Further research multi-center trials essential validate these facilitate approval implementation.

ABSTRACT The metazoan lifespan is determined in part by a complex signaling network that regulates energy metabolism and stress responses. Key hubs this include insulin/IGF‐1, AMPK, mTOR, sirtuins. Hippo/Mammalian Ste20‐like Kinase1 (MST1) pathway has been reported to maintain Caenorhabditis elegans , but its role not studied higher metazoans. In study, we report overexpression of Hpo, the MST1 homolog Drosophila melanogaster decreased with concomitant changes lipid aging‐associated gene expression, while RNAi Hpo depletion increased lifespan. These effects were mediated primarily Hpo‐induced transcriptional activation RNA‐binding protein maternal expression at 31B (Me31b)/RCK, resulting stabilization mRNA‐encoding lipolytic hormone, Akh. mouse adipocytes, Hpo/Mst1 adipocyte differentiation, phosphorylation proteins such as Rck, decapping MRNA 2 (Dcp2), enhancer Of 3 (Edc3), nucleolin (NCL), glucagon mRNA stability interacting Rck. Decreased Hpo‐overexpressing lines required Me31b, DCP2, which was potentially recovering metabolic genes formation droplets. Taken together, our findings suggest plays conserved longevity regulating adipogenesis fatty acid metabolism.

Preventing disease and maintaining the health of elderly are crucial goals for an aging population, with obesity immune function restoration being paramount importance. Obesity, particularly visceral characterized by excessive fat accumulation around abdominal organs, is linked to chronic conditions such as diabetes, hypertension, cardiovascular diseases, dysfunction. Globally, considered a disease, prompting significant research interest in its treatment. Therefore, it essential explore potential therapeutic preventive strategies address decline brought about aging.
