Type 2 Diabetes mellitus is a major global health concern. MicroRNA plays an important role in regulating pancreatic beta cells as well as peripheral insulin signaling. This study aimed to identify reference microRNA s in type 2 Diabetes mellitus plasma and validate two target microRNAs among a Sri Lankan population with type 2 diabetes mellitus.
This is a cross-sectional experiment. A total of fifty-three (N = 53) non-hemolyzed plasma samples from individuals with type 2 diabetes mellitus were selected to evaluate stability, in comparison to thirty-eight (N = 38) normoglycemic non-hemolyzed plasma samples. Initially, the stability of four candidate reference microRNAs (hsa-miR-16-5p, hsa-miR-425-5p, hsa-miR-191-5p, and hsa-miR-22-5p) was assessed. Stability was analyzed using the geNorm and BestKeeper algorithms. The relative expression changes of hsa-miR-29a-3p and hsa-miR-375-3p in the plasma of the same samples were evaluated using the validated reference microRNAs. The selected regulatory microRNAs were directly linked with type 2 diabetes mellitus pathogenesis and proved to be upregulated in type 2 diabetes mellitus plasma and serum.
The expressions of miR-16-5p and miR-191-5p were not stable between the two groups, miR-22-5p and miR-425-5p levels were found to be stable. A significant upregulation of hsa-miR-29a-3p and hsa-miR-375-3p was observed in type 2 diabetes mellitus patients compared to normoglycemic individuals (p ≤ 0.05). This was the first study to claim hsa-miR-425-5p and hsa-miR-22-5p as stably expressed reference microRNAs in type 2 diabetes mellitus patients. Sri Lankan type 2 diabetic patients also had increased hsa-miR-29a-3p and hsa-miR-375-3p levels. However, large and well-matched sample studies were suggested to ensure that these microRNAs can be used as type 2 diabetes diagnostic markers in Sri Lanka.
2型糖尿病是全球主要的健康问题。微小RNA在调节胰岛β细胞以及外周胰岛素信号传导中发挥重要作用。本研究旨在鉴定2型糖尿病血浆中的参考微小RNA,并在斯里兰卡2型糖尿病患者群体中验证两个靶标微小RNA。
这是一项横断面实验。与38份非溶血正常血糖血浆样本相比,共选取53份2型糖尿病患者的非溶血血浆样本评估稳定性。最初,评估了四种候选参考微小RNA(hsa-miR-16-5p、hsa-miR-425-5p、hsa-miR-191-5p和hsa-miR-22-5p)的稳定性。使用geNorm和BestKeeper算法分析稳定性。使用经过验证的参考微小RNA评估相同样本血浆中hsa-miR-29a-3p和hsa-miR-375-3p的相对表达变化。所选的调节性微小RNA与2型糖尿病发病机制直接相关,并被证明在2型糖尿病血浆和血清中上调。
两组之间miR-16-5p和miR-191-5p的表达不稳定,发现miR-22-5p和miR-425-5p水平稳定。与正常血糖个体相比,2型糖尿病患者中观察到hsa-miR-29a-3p和hsa-miR-375-3p显著上调(p≤0.05)。这是第一项声称hsa-miR-425-5p和hsa-miR-22-5p为2型糖尿病患者中稳定表达的参考微小RNA的研究。斯里兰卡2型糖尿病患者的hsa-miR-29a-3p和hsa-miR-375-3p水平也有所升高。然而,建议进行大规模且匹配良好的样本研究,以确保这些微小RNA可作为斯里兰卡2型糖尿病的诊断标志物。
