Figure Lengend Snippet: A , B CCK-8 assay to detect the inhibitory effect of NRG1 on cell death induced by Erastin, Nigericin, Hydroxyurea, and Wogonoside in BC cells ( n = 3). C Transmission electron microscopy to observe mitochondrial damage in MDA-MB-231 cells. Scale bar = 2 μm (Zoom in = 1 μm). D , E Western blot to detect the effect of exogenous NRG1 on the AKT/mTOR pathway in BC cells ( n = 3). F , G Western blot to observe the effect of CAF-derived NRG1 on the AKT/mTOR pathway in BC cells ( n = 3). Data are expressed as the mean ± S.D. for all panels: ns = no significance, # P < 0.05, ** , ## P < 0.01, ***,### P < 0.001.
