“…Shen et al 14 detected that the most significant difference in tRFs, specifically tRF‐Glu‐TTC derived from adipose tissue, occurred in rats fed an HFD, inhibiting preadipocyte differentiation and gene levels that are related to adipogenesis. Zhang et al 15 discovered that in the adipose tissue of overweight diabetic patients, tRF‐1‐28‐Glu‐TTC‐3‐M2 is up‐regulated, while tRF‐1‐31‐His‐GTG‐1 is down‐regulated, suggesting a potential role for tsRNAs in the development of diabetes mellitus. Atherosclerosis (AS) is a chronic inflammatory disease affecting the cardiovascular system.…”

BackgroundGestational Diabetes Mellitus (GDM) poses significant risks to maternal and fetal health. Current diagnostic methods based on glucose tolerance tests have limitations for early detection. tRNA‐derived small RNAs (tsRNAs) have emerged as potential molecular regulators in various diseases, including metabolic disorders. However, the diagnostic value of tsRNAs in plasma for early GDM or postpartum remains unclear.MethodsThis longitudinal study profiled the expression of tsRNAs across different gestational stages and postpartum in women with GDM (n = 40) and healthy control gestational women (HCs, n = 40). High‐throughput small RNA sequencing identified candidate tsRNAs, which were then validated and correlated with clinical biochemical markers such as fasting blood glucose (FBG), HOMA‐IR, and GHbA1c.ResultstRF‐1:32‐Val‐AAC‐1‐M6, tRF‐1:31‐Glu‐CTC‐1‐M2, and tRF‐1:30‐Gly‐CCC‐1‐M4 were consistently upregulated in the GDM group compared to HCs during the second trimester (p < 0.05). Only tRF‐1:31‐Glu‐CTC‐1‐M2 was highly expressed during the first trimester, and tRF‐1:30‐Gly‐CCC‐1‐M4 increased during postpartum. tRF‐1:31‐Glu‐CTC‐1‐M2 showed a significant correlation with FBG levels in the first trimester (R = 0.317, p = 0.047). The expression of tRF‐1:30‐Gly‐CCC‐1‐M4 was significantly correlated with HOMA‐IR (r = 0.65, p < 0.001) and GHBA1c (r = 0.33, p = 0.037) during postpartum. A joint diagnostic model incorporating tsRNAs expression and clinical markers demonstrated enhanced predictive power for GDM (ROC AUC = 0.768).ConclusionOur results revealed distinct expression patterns of specific tsRNAs in GDM, showcasing their correlation with key metabolic parameters. This underscores their promising role as biomarkers for early prediction and diagnosis of GDM. The integration of tRFs into a composite biomarker panel holds the potential to improve clinical outcomes by enabling personalized risk assessment and targeted interventions.
