PAQR3 aggravates ferroptosis in ALL. (A) The cell viability of CEM‐C1 and Jurkat cells was verified through CCK‐8 assay in the Vector + DMSO, PAQR3 + DMSO, Vector + RSL3, PAQR3 + RSL3, Vector + RSL3 + Fer‐1, and PAQR3 + RSL3 + Fer‐1 groups. (B–D) The levels of MDA, DCF and Fe in CEM‐C1 and Jurkat cells were tested through the appropriate kits in the Vector + DMSO, PAQR3 + DMSO, Vector + RSL3, PAQR3 + RSL3, Vector + RSL3 + Fer‐1, and PAQR3 + RSL3 + Fer‐1 groups. (E) The apoptosis rate of CEM‐C1 and Jurkat cells was measured through flow cytometry in the Vector + DMSO, PAQR3 + DMSO, Vector + RSL3, PAQR3 + RSL3, Vector + RSL3 + Fer‐1, and PAQR3 + RSL3 + Fer‐1 groups. Fer‐1: 1 μM; RSL3: 0.1 μM. *p < .05, **p < .01; #
