abstract

background nesfatin-1 is a protein derived from a precursor molecule of the nucleobindin-2 gene, and acts as an anorexigenic peptide on food intake behavior, and its level isinfluenced by nutritional status, food composition [fat and carbohydrate (cho)], and physical exercise. objectives the aim of this study was to investigate the effects of 6 weeks of treadmill running (at high intensity) program with and without zizyphus jujuba (high carbohydrate content) crud extraction on liver nesfatin-1, atp, glycogen, and its plasma concentrations in female rats. conclusions the findings indicate that higher liver nesfatin-1 and glycogen content by zj extraction might be due to the zj high cho content, and it could be consideredas an anti-appetite herb. materials and methods twenty-eight wistar female rats (6-8 weeks old100-120 g of weight) were randomly assigned to saline-control (sc), saline-training (st), zizyphus jujuba-control (zjc), and zizyphus jujuba-training (zjt) groups. rats ran on a motor-driven treadmill at 35 m/min, 60 min/day, 5 days/week for 6 weeks. animals received zj extraction and saline at the dose of 1.25ml/100g of body weight. seventy-two hours after the last training session rats were killed, a portion of liver excited, and plasma was collected for nesfatin-1, atp, and glycogen measurements. a one-way anova method, and pearson correlation were employed. p < 0.05 was considered as significant. results a higher and significant liver nesfatin-1 level was found in zj groups (p < 0.005), but plasma nesfatin-1 responded differently. changes in liver nesfatin-1 were accompanied with an increase in liver glycogen,but not atp contents.

ABCG5 gene responses to treadmill running with or without administration of Pistachio atlantica in female rats

  Objective(s): ABC transporters comprise a large family of transmembrane proteins that use the energy provided by ATP hydrolysis to translocate a variety of substrates across biological membranes. All members of the human ABCG subfamily, except for ABCG2, are cholesterol-transporter. The aim of this study was to determine the liver, the small intestine and kidney ABCG5 relative gene expression...
