There are many indications that confirm the vital role of adipocytokines and PPARγ in diabetics. Hence, the current investigation aimed to study the modulatory effects of gallic acid and p-coumaric acid on adipocytokines secretion and PPARγ mRNA expression in type 2 diabetic rats. After induction of type 2 diabetes, diabetic rats were orally treated with 20 mg/kg body mass gallic acid and 40 mg/kg body mass p-coumaric acid for six weeks. Among treatment diabetic rats, glucose and glycosylated hemoglobin levels significantly declined in diabetic rats, while insulin level and body weight significantly increased as compared to control group. Gallic acid and p-coumaric acid markedly decreased the level of TNF-α and increased the levels of PPARγ mRNA and adiponectin. In addition, the tested agents improved markedly lipid profile parameters, cardiovascular indices 1 and 2 and anti-atherogenic index. In conclusion, gallic acid and p-coumaric acid exhibited marked antidiabetic action that could be mediated via modulation of TNF-α and adipocytokines secretions as well as upregulation of PPARγ mRNA expression.
