Abstract: To study expressions of HSPs mRNA in different tissues of sows during late gestation stage in thermal environment, twelve sows (Landrace x Large White) were selected and randomly assigned to 2 groups. All sows were sacrificed on day 90 and 110 of gestation, respectively and the brain, heart, liver, kidneys, spleen, lung and ovary samples were collected to determine the expression of HSP70 and HSP90 mRNA. The HSP70 mRNA expression abundance in different tissues of sows on day 90 of gestation was as follows: lung>spleen> liver>brain and HSP90 with lung>kidneys>ovary>brain on day 110, HSP70: lung>spleen>liver>brain and HSP90 with lung>ovary>spleen>kidneys. Compared with the day 90, the relative expressions of HSP70 and HSP90 mRNA were lower in lung (p<0.01) and HSP90 mRNA was lower in those of day 110 (p<0.01). These findings show distinct tissue specificity and the higher expressions of HSP70 and HSP90 mRNA in lung indicated that continuous hot weather may cause stress in lung and this may be important information to prevent heat stress during late gestation in thermal environment.
