Core Tip: Obesity and being overweight are widespread health issues in modern societies, and their growing prevalence poses a serious public health challenge due to both the financial burden and health risks involved. In humans, the expression of miRNAs in adipose tissue has been demonstrated to be associated with various metabolic factors, including body mass index, adipogenesis, blood sugar levels, and leptin concentrations. The microRNA (miRNA)-200 family is reported to be more prevalent in human β-cells than in α-cells. The expression of miRNA-200a and miRNA-200b is regulated by thioredoxin-interacting protein, a proapoptotic regulator. It has been suggested that a deficiency in vitamin D is closely associated with obesity and plays a role in the development of insulin resistance and type 2 diabetes mellitus (T2DM). Studies have indicated that vitamin D influences the expression of miRNAs both in adipocytes in laboratory settings and in adipose tissue in living organisms. Therefore, the current work examines miRNA-200a and miRNA-200b expression, and vitamin-D level in obese non-diabetic and obese T2DM individuals.
