Deubiquitylase USP52 Promotes Bladder Cancer Progression by Modulating Ferroptosis through Stabilizing SLC7A11/xCT
We identified USP52 as a DUB that cleaves K48-linked ubiquitin at K4 and K12 of xCT. Loss of USP52 reduces cell proliferation by decreasing xCT and enhancing ferroptosis sensitivity. Combining USP52 depletion with IKE strongly inhibits BLCA progression, presenting a new potential therapy.
