The category GO:0006939~smooth muscle contraction included four differentially expressed genes (i.e., ACTG2, EDNRB, AGT, MYH11) in the fatal asthma- vs. non-asthma-derived ASM comparison, six differentially expressed genes (i.e., KCNMA1, EDNRB, CACNA1G, BDKRB2, CACNA1C, GDNF) in the non-asthma-derived ASM baseline vs. vitamin D treatment comparison, and four differentially expressed genes (i.e., KCNMA1, EDNRA, ACTG2, AGT) in the fatal asthma-derived ASM baseline vs. vitamin D treatment comparison, with Benjamini-Hochberg corrected p-values of 0.80, 0.22 and 0.69, respectively. Here, EDNRA is linked to asthma.
