From: Regulation of gene expression in chickens by heat stress
Consequences of heat stress on the chicken early response system. The gene expression of heat shock protein, brain-derived neurotrophic factor, c-FOS like protein and neuronal nitric oxide synthase is increased (↑) while the expression of the caudal gene is yet to be established (↔). The diagram is drawn based on the articles [40,41,42,43]
