LINC01173: LINC01173, a long non-coding RNA (lncRNA), has been implicated in TSH adenomas and type 2 diabetes mellitus (T2DM) [PMC7652879]. Increased expression of LINC01173, along with alterations in vitamin D levels and smoking habits, may contribute to the severity and pathogenesis of T2DM [PMC9397532]. Vitamin D insufficiency has long been suspected as a risk factor for diabetes [PMC9397532]. T2DM cases with GAD autoantibody showed higher expression of LINC01173 compared to cases without autoantibody [PMC9397532]. T2DM cases with hypertension, impaired wound healing, and blurred vision also exhibited higher expression of LINC01173 [PMC9397532]. A study among Saudi T2DM cases found significantly higher expression of LINC01173 compared to controls [PMC9397532]. Smoking was associated with increased LINC01173 expression in T2DM cases [PMC9397532]. The association between LINC01173 and vitamin D levels was also analyzed, revealing higher expression in vitamin D-deficient cases compared to insufficient and sufficient levels [PMC9397532]. The study concluded that the risk of T2DM may be associated with higher expression of LINC01173, altered vitamin D levels, and smoking habits [PMC9397532].
