The target genes TNF, ABCB1 and TGFB1, described from the intersection of the genes retrieved from the five databases, known CF GMs and the HPGD, were then mapped to their biological process pathways using the Venn Viewer function in CTD (https://ctdbase.org/tools/vennViewer/). Here, ABCB1 is linked to cystic fibrosis.
