Figure 3From: Effect of H2S on the circadian rhythm of mouse hepatocytesEffect on expression of Per2 gene in primary cultured hepatocytes. Horizontal axis shows the period and vertical axis shows the amplitude. The mRNA levels of Per2 gene were normalized to GAPDH mRNA. Each value represents the mean ± SD (n = 3). The expression differences were assessed by one-way ANOVA.Back to article page
