Figure 1. — (a) Reverse transcription quantitative (RT-q)PCR analysis of acyl-CoA synthetase long chain family member 4 (ACSL4) expression in normal bronchial epithelial cells (HBE) and non-small-cell lung cancer (NSCLC) cell lines (A549, NCI-H1975, SK-MES-1, and PLA-801D). (b) Terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) staining was used to assess cell death levels after erastin intervention in the cell lines. (c) Correlation analysis of both ACSL4 and ferroptosis induced by erastin. **p < 0.01, ***p < 0.001.
