PPARG and asthma: After functional analysis of genes in the coexpression network, five KEGG pathways (“ECM-receptor interaction,” “focal adhesion,” “beta-alanine metabolism,” “PI3K-Akt signaling pathway,” and “pathways in cancer”) contained 8 genes (VWF, LAMB3, LAMA4, CAV1, ALDH1A3, SMOX, GNG4, and PPARG) which were found to be directly related to childhood asthma development and have potential for use as disease progression biomarkers.
