Abstract

The whey protein (WP) has shown various properties and health effects. Recently, we reported that WP was able to increase expression of HSP70 in various tissues. The heat shock proteins (HSP) are composed of several families which represent a protective system that favors cellular resistance and tolerance before unfavorable conditions for the organism. It is believed that the high content of branched chain amino acids (BCAA) is an important factor involved in the ability of PSL increase in HSP70. The objective of this study is to investigate the influence of the consumption of whey protein as protein source in the diet on the expression of other HSPs, and also check the influence of amino acids and peptides present in the WP and associated parameters of HSPs. Methods: we will use in the first experiment, 48 male rats were divided primarily into 2 groups: sedentary and exercised. Each group is divided into three dietary groups (receiving AIN 93-G protein replacement): whey protein concentrate (WPC), whey protein hydrolyzate (WPH), casein (CAS) as a control. The animals of group exercised will be submitted to exercise on a treadmill as a source of heat stress. The following parameters will be determined: free amino acids in the plasma, HSP25, HSP60, HSP90, AHA1, DHFR, NOS, VEGF, PI3-Kinase, BCKDH, SOD, Catalase, GPx, p-AKT, GFAT, OGT, HSF1, HSF1 phosphorylated. In Experiment 2, we use 90 male rats were divided into 10 groups, which are gavados one of the following amino acids: leucine, valine, isoleucine, glutamine and arginine, or peptides: isoleucine-leucine, leucine-isoleucine, valine, leucine, leucine-valine in comparison with WPH. The animals will be subjected to the exercise as a source of stress. The following parameters are determined: free amino acids in the plasma, HSP25, HSP60, HSP90, HSP70, AHA1, DHFR, NOS, VEGF, PI3-Kinase, BCKDH, SOD, Catalase, GPx, p-AKT, GFAT, OGT, HSF1, HSF1 phosphorylated. The results will be statistically analyzed using ANOVA with significance set at p d 0.05, and Tukey's test. (AU)
