GCLC and monocytic leukemia: Such an opposing regulation of SLC7A11 and GPX4 relative to major NRF2 target genes (GCLC, GCL modifier subunit [GCLM], NAD(P)H quinone dehydrogenase 1 [NQO1], HO‐1) has, however, previously been observed, for example, for phorbol 12‐myristate 13‐acetate (PMA)‐treated human THP‐1 monocytic leukemia cells,224 and is not necessarily an indicator for NRF2 inhibition.
