From: Chronic heat stress induces renal fibrosis and mitochondrial dysfunction in laying hens
Effect of chronic heat stress on the functionality of mitochondria in the kidney. a ATP levels in renal tissue. n = 8 in each group. Data are presented as the percentage of the total cortex and as the mean ± SEM. Statistical analysis was performed using a Student’s t-test. b mtDNA copy number of renal tissues in laying hens. mt/nucDNA = mtDNA relative to nuclear DNA (β-actin) copy number. *P < 0.05
