Abstract
Apelin and its receptor (APJ) are involved in the regulation of a variety of pathophysiological processes. We studied the effect of apelin treatment on obesity-induced type 2 diabetes mellitus (T2DM) and possible interaction between apelin/APJ system and renin-angiotensin system (RAS). Forty eight male albino rats were divided into two groups: control group and diabetic group. Diabetic group was subdivided into: control diabetic, apelin-treated, apelin + losartan-treated, apelin + l-NAME-treated and losartan-treated diabetic subgroup. Administration of apelin-13 yielded an improvement of IR, dyslipidaemia, inflammation, oxidative stress with significant decrease in AT1R gene expression and significant increase in ACE2 gene expression in adipose tissues. Losartan + apelin yielded a further significant decrease in ATR1 gene expression, glycaemic indices, serum TGs and TPA versus Apelin only. Adding l-NAME in subgroup (2D) reversed the effect of apelin. We suggested that the beneficial effect of Apelin is mainly mediated by NO-activated pathway and/or ACE2/Ang (1-7) dependent pathway.
