Figure 7. lncRNA ZFAS1 affects TGF-β1-induced ferroptosis in HFL1 cells by regulating the miR-150-5p/SLC38A1 axis. (A, B) Western blot was performed to detect the level of GPX4 protein; (C) the level of ROS was measured by ROS kit; (D) The MDA content was measured by lipid peroxidation (MDA) assay kit; **P<0.01, ***P<0.001, compared with the control group; ##P<0.01, ###P<0.001, compared with the TGF-β1 group; ▲▲P<0.01, ▲▲▲P<0.001, compared with the TGF-β1+si-SLC38A1 group.
