BRCA1 and nasopharyngeal carcinoma: Therefore, in this study, it is suggested that the core ceRNA network, specifically the hsa_circ_0004277/hsa-miR-24-3p/BRCA1 and hsa_circ_0004277/hsa-miR-92b-3p/BRCA1 axes, is most likely to influence the progression or suppressing of the pathophysiological processes of PD in NPC patients undergoing radiotherapy.
