Specifically, GO:0048661~positive regulation of smooth muscle cell proliferation included seven differentially expressed genes (i.e. PRKCA, IL6, S1PR1, PTGS2, VEGFA, IGF1, ITGA2) in non-asthma-derived ASM and six differentially expressed genes (i.e. CDH13, VEGFA, TGM2, IGF1, ITGA2, STAT1) in fatal asthma-derived ASM, with Benjamini-Hochberg corrected p-values of 0.066 and 0.14, respectively. This evidence concerns the gene ITGA2 and asthma.
