This study aimed to estimate changes in HSF3 and HSP70 mRNA expression in stress-sensitive tissues of 2 chicken breeds during acute heat stress. Lingshan chickens (LSC) and White Recessive Rock (WRR) (24 chickens of each breed) were randomly divided into 4 groups (0, 2, 3, and 6 h of heat treatment). With increasing heat treatment time, both HSF3 and HSP70 expression first declined and then showed a significant increase in both breeds. However, HSP70 expression decreased in the heart following 6 h of heat treatment, whereas HSF3 expression continued to increase. After 2 h of heat treatment, HSF3 expression was significantly higher in the brain and leg muscle of LSC compared to WRR (P &lt; 0.05, P &lt; 0.01). In comparison, HSP70 expression was significantly higher in the liver and leg muscle of WRR compared to LSC (P &lt; 0.01, P &lt; 0.05). After 3 h of heat treatment, HSF3 expression was significantly higher in the brain and leg muscle of LSC compared to WRR (P &lt; 0.01). In comparison, HSP70 expression was significantly higher in the liver and heart of LSC compared to WRR (P &lt; 0.01). These results indicate that the expression of HSF3 and HSP70 mRNA in LSC and WRR exhibit species-specific and tissue-specific differences during heat treatment.
