GPX4 and chronic myelogenous leukemia, BCR-ABL1 positive: Finally, we also detected GPX4 expression in K562 and K562/IR cells and CML samples, and the results showed that GPX4 expression in K562/IR cells was lower than that in K562 cells, and there was no significant difference in GPX4 expression between BC-CML and CP-CML samples and normal samples (Figures 7M, N).
