KAT6A, known as a histone acetyltransferase, binds to and modifies chromatin in cancer cells.[11, 20] In this study, we observed lower levels of chromatin‐bound KAT6A‐WT in PARPi‐resistant ovarian cancer cells compared to PARPi‐sensitive ones (Figure 3D). Here, KAT6A is linked to ovarian carcinoma.
