Adipose tissue plays an important role in regulating glucose and lipid metabolism and maintaining insulin sensitivity. Apart from lowering blood glucose levels, antidiabetic drugs may also directly affect adipocyte function. The present study was conducted to compare the effects of common anti-diabetics, metformin, dapagliflozin, sitagliptin, pioglitazone, and glimepiride on 3T3-L1 derived adipocytes. Gene expression of key players involved in adipogenesis, lipid metabolism, adipokine production and inflammation was analyzed using quantitative real-time PCR. Each drug produced a distinct pattern of gene expression of these selected markers. Sitagliptin showed the strongest increase in the expression of adipogenic and lipid metabolism-related genes, suggesting improved adipocyte function. Pioglitazone markedly increased adiponectin expression with reduced inflammatory gene expression, indicating enhanced insulin sensitivity and adipocyte function. Glimepiride moderately increased the expression of adipogenic genes while reducing TNF-α expression, suggesting mild anti-inflammatory effects. Metformin caused only minor changes in most genes, with a noticeable reduction in PPARγ expression. Dapagliflozin increased the expression of genes involved in fatty acid uptake and lipid storage but also increased TNF-α expression. Overall, the findings demonstrate that different antidiabetic drugs have distinct effects on adipocyte gene expression, highlighting their diverse roles in regulating adipocyte metabolism and function beyond their glucose-lowering effects.
