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. This evidence concerns the gene NQO1 and monocytic leukemia.
