Next, flow cytometric analysis was used to investigate the roles of BIRC2 in BRD7-mediated cell cycle progression and apoptosis in NPC, and the results showed that BRD7 induced G1/S arrest and induced apoptosis as expected, while the restoration of BIRC2 significantly reversed the effects of BRD7 on the inhibition of cell cycle progression and apoptosis promotion (Fig. 4D). This evidence concerns the gene BRD7 and nasopharyngeal carcinoma.
