In addition, 10 potential drugs were identified to reverse the expression of TIMP1. It has been shown that after glucocorticoid treatment, the expression level of TIMP1 in patients with idiopathic pulmonary fibrosis (IPF) were significantly lower than those before glucocorticoid treatment (p < 0.05) (Zhang et al., 2015). The gene discussed is TIMP1; the disease is pulmonary fibrosis.
