RNA sequencing analysis on male (M) and female (F) hearts in normoxia control (C) or hypoxia (H) group. A: Number of differentially expressed genes in MH vs. MC, FH vs. FC, and FH vs MH mice as presented in bar graphs. B: GO analysis depicted dot plots of male and female mice with most significantly activated or suppressed biological processes including mitosis, angiogenesis, apoptosis, and immune cell response. C: Heat maps of relative expression level of genes involved in G1 to S phase transition (GO:0000082) in MH vs. MC mice. Upregulated and downregulated genes shown as red and blue, respectively (n=3 each group).
