A: Assessment of relative mRNA expression level of HSP 70.1 gene in heat stressed PBMCs isolated from Tharparkar and Vrindavani cattle at 37°C, 40°C, 41°C and 42°C respectively. Data are represented as mean ± s.e.m. Levels (within time) not connected by same letter are significantly different (P<0.05).
