The Association of Different Cells. Wu et al. [92, 93] ascertained that lncRNA-CHRF expression was increased, and miR-489 expression was decreased in a murine model of silicosis, in SiO2 dust–treated macrophages (mouse RAW264.7 and human THP-1 macrophages), and in NIH/3T3 cells and MRC-5 cells treated with TGF-β. Here, TGFB1 is linked to silicosis.
