Our analysis revealed that miR-33 inhibition attenuated multiple genes from the IPF macrophage’s signature list, including CHI3L1, CHIT1, MERTK, CTSK, ITGB5, FN1 (fibronectin 1), LGMN (legumain), LPL (lipoprotein lipase), FABP5 (Fatty acid binding protein 5), LIPA (lipase A), and CTSZ (cathepsin Z) (Figure 8H and Supplemental Table 5). The gene discussed is CTSK; the disease is idiopathic pulmonary fibrosis.
