Figure 3From: Beta-estradiol attenuates hypoxic pulmonary hypertension by stabilizing the expression of p27kip1 in rats Effects of β-E2 on p27 and Skp-2 expression in rat lungs and cultured rat PASMCs. (a) Representative Western blotting analysis of p27 and Skp-2 protein levels in rat lungs. (b) Representative Western blotting analysis of p27 and Skp-2 protein levels in cultured rat PASMCs. *P < 0.05, significant difference from the hypoxia group. # P < 0.05, significant difference from the normoxia group. $ P < 0.05, significant difference from the hypoxia group. & P < 0.01, significant difference from the normoxia group. Values are expressed as mean ± SD (n = 3).Back to article page
