عنوان انگلیسی Evaluation of Tnf-α and Il-6 mRNAs expressions in visceral and subcutaneous adipose tissues of polycystic ovarian rats and effects of resveratrol
چکیده انگلیسی مقاله Objective(s): Some studies suggest that chronic low-grade inflammation is involved in insulin resistance in polycystic ovary syndrome (PCOS). This study assessed possible involvement of alteration in expression of two pro-inflammatory factors, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in adipose tissues of PCOS rats in the impairment of insulin actions. Also, effects of resveratrol as an anti-inflammatory agent were investigated. Materials and Methods: Fifteen female Wistar rats (21 days old) were divided into three groups (n=5): Ι) Control, П) PCO-model-saline: served as PCOS rats and to induce PCOS, received subcutaneously testosterone enanthate 1 mg/100 g body weight subcutaneously for 35 days, Ш) PCO-model-resveratrol, after receiving testosterone, received resveratrol 10 mg/kg intraperitoneally for 28 days. The expression of Tnf-α and Il-6 mRNAs in adipose tissues was determined by the qRT-PCR method. Results: The Il-6 mRNA expression in the visceral adipose tissue of PCOS rats was increased in comparison to controls (P< 0.05). Tnf-α and Il-6 mRNA expression in visceral and subcutaneous adipose tissues of polycystic ovarian rats was similar to controls. The expression of Tnf-α mRNA in subcutaneous adipose tissue and Tnf-α and Il-6 mRNAs in the visceral adipose tissue of the PCO-model-resveratrol group were lower than PCOS rats (P< 0.05). Conclusion: Increased expression of Il-6 mRNA in the visceral adipose tissue of polycystic ovarian rats may be one cause of insulin resistance observed in them and resveratrol as an anti-inflammatory and anti-hyperglycemic agent may decrease the risk of diabetes by reduction of expression of pro-inflammatory cytokines TNF-α and IL-6 in PCOS patients.
