NONO and ovarian carcinoma: NONO, a multifunctional DNA‐ and RNA‐binding protein, has been implicated in several biological processes through its role in regulating gene transcription and translation.[25, 26] It is well established that NONO physically binds to the carboxy‐terminal domain (CTD) of the largest subunit of eukaryotic RNA polymerase II (RNA pol II).[27] To confirmed this association in ovarian cancer cells, we performed co‐immunoprecipitation (Co‐IP) experiments in MDAH2774 cells.
