Finally, the genes that are induced by hypoxia and that are shared in different cells lines from IPF, Table 2 and Table 3 show the 19 DEGs, divided into up- and down-regulated; there is some discrepancy in the four down-regulated genes in our study because previous studies in IPF report them up-regulated, and this is the case with Coagulation factor III (F3), Hedgehog interacting protein (HHIP), Interleukin 6 (IL-6), and Stanniocalcin 1 (STC1) (Table 2). This evidence concerns the gene HHIP and idiopathic pulmonary fibrosis.
