In addition, analogously to what was observed with CA IX/XII targeting in the stromal compartment, inhibition of CA IX/XII in tumor cells sensitized lactic acid‐primed PCa cells to RSL3‐induced ferroptosis, while Ferrostatin‐1 blocked the reduction of cell survival (Fig. 5D and Fig. S3E). The gene discussed is CA9; the disease is posterior cortical atrophy.
