The objective of this study was to investigate the kinetics of Hsp60, Hsp70, Hsp90 protein, and messenger RNA (mRNA) expression levels and to correlate these heat shock protein (Hsp) levels with tissue damage resulting from exposure to high temperatures for varying amounts of time. One hundred broilers were heat-stressed for 0, 2, 3, 5, and 10 h,(More)
1. In order to understand the distribution and variation of Hsp90 and its corresponding mRNA in the tissues of heat-stressed broilers, 100 experimental birds were heat stressed for 0, 2, 3, 5 and 10 h. 2. Both nuclear and cytoplasmic Hsp90-positive signals were observed in myocardial cells, hepatocytes and renal tubule epithelial cells. The expression of(More)
This study investigates the effect of different transport times on meat quality and the correlation between meat quality and Hsp expression in M. longissimus dorsi (LD) of pigs. After transportation for 1h, 2h or 4h, respectively, blood plasma creatine kinase (CK) and lactate dehydrogenase (LDH) increased. The LD meat from 1h and 2h transported pigs had(More)
The objective of this study was to investigate the expression and localization of HSP60 in the heart, liver, and kidney of acutely heat-stressed broilers at various stressing times. The plasma creatine kinase (CK) and glutamic pyruvic transaminase (GPT) concentrations statistic increased following heat stress. After 2h of heat stress, the tissues showed(More)
The objective of this study was to investigate the expression and localization of heat shock protein 70 (Hsp70) and its mRNA in the heart, liver, and kidney of acutely heat-stressed broilers at various stressing times. Male AA broilers (n = 100) were randomly divided into 5 groups of 20 birds per group. After 30 d of adaptive feeding at ambient temperature,(More)
