PARP1 and ovarian carcinoma: LLPS, a reversible molecular process involving proteins or nucleic acids, participates in many biological activities, including gene transcription,[36] genome organization,[37] epigenetic modification,[38] and signal transduction.[39] Moreover, LLPS of cancer‐related proteins is important to the occurrence, development, and drug resistance of tumors.[40] KAT6A can form aggregated droplets in the nuclei of PARPi‐resistant ovarian cancer cells, and KAT6A LLPS is essential for the interaction between KAT6A and PARP1.
