Fig. 4From: Integrative analyses of gene expression profile reveal potential crucial roles of mitotic cell cycle and microtubule cytoskeleton in pulmonary artery hypertensionViolin diagram showing the expression levels of five hub genes are highly corrected with PAH, especially with IPAH and SSc-PAH. These hub genes include CHEK1 (a-b), SMC2 (c-d), SMC4 (e-f), KIF23 (g-h) and CENPE (i-j). P-values were respectively obtained from two-sample Wilcoxon test and multiple-sample Kruskal−Wallis testBack to article page
