Abstract

Background: It is well established that the excess cellular cholesterol concentration, as well as high density lipoprotein (HDL) and total cholesterol levels are strongly correlated with the incidence of coronary artery disease (CAD). Reverse cholesterol transport (RCT) is a term used to describe the efflux of excess cellular cholesterol. ABCG8 is a member of ABCG family that play a critical role in this process.

Objectives: The current study was conducted to investigate the effect of endurance exercise with or without Pistachia atlantica (Baneh) extraction on small intestine and kidney ABCG8 gene, also plasma high density lipoprotein (HDL-c), triglyceride (TG), total cholesterol (TC), glucose, and estrogen levels in female rats.

Materials and Methods: In this study twenty Wistar female rats (six to eight weeks old, 125-135 g weight) were used. Animals were randomly assigned into training (n = 10) and control (n = 10) groups and further divided into saline-control (SC), saline-training (ST), Baneh-control (BC), and Baneh-training (BT) groups. Training groups was given exercise on a motor-driven treadmill at 25 m/min (0% grade) for 60 min/day, 5 days/week for eight weeks. Animals were fed orally with Baneh extraction and saline for four week. After the last training session, rats were sacrificed, small intestine and kidney were excised, and ABCG8 expression was detected by Real-time PCR method. Plasma also was collected for plasma variable measurements. Statistical analysis was performed using a one way analysis of variance, and significance was accepted at P < 0.05. Correlation was calculated using the Pearson Product Moment correlation.

Results: Exercise increased (P < 0.01) and Baneh reduced intestinal ABCG8 mRNA (P < 0.05). In kidney tissue, there wasnt significant change between the groups (P < 0.40). Plasma HDL-C level was increased by exercise (P < 0.05) and decreased by Baneh (P < 0.02) that was correlated by intestine ABCG8 (r = 0.81, P < 0.001). Plasma TG and TC were unchanged, but glucose and estradiol were increased and decreased in Baneh groups (P < 0.02), respectively.

Conclusions: Our study shows that exercise increases intestinal ABCG8 mRNA, and Baneh can increase plasma glucose concentration and reduce ABCG8 expression, HDL-C, and estrogen levels probably due to high fatty acid components.
