ACTA2 and idiopathic pulmonary fibrosis: Both control and IPF fibroblasts exhibited a prominent trend toward ACTA2 up-regulation; however, this was not statistically significant (FC > 5 in all stimulated cells) (Figure 6M), with mean FC = 176.6 for control fibroblasts and mean FC = 51.2 for IPF fibroblasts compared with unstimulated cells (FC = 1).
