- Abstract
Novel target therapy is on the spotlight for effective cancer therapy. Hence, in the present study, the underlying apoptotic mechanism of Morusin was explored in association with miR193a-5p mediated ZNF746/c-Myc signaling axis in colorectal cancer cells (CRCs). Herein, Morusin reduced the viability and the number of colonies in HCT116 and SW480 CRCs. Additionally, Morusin increased sub-G1 population, cleavages of poly (ADP-ribose) polymerase (PARP) and caspase-3 and inhibited the expression of zinc finger protein 746 (ZNF746) and c-Myc in HCT116 and SW480 cells. Conversely, overexpression of ZNF746 suppressed the ability of Morusin to abrogate the expression of c-Myc in HCT116 cells, as ZNF746 enhanced the stability of c-Myc via their direct binding through nuclear colocalization in HCT116 cells by immunofluorescence and immunoprecipitation. Notably, Morusin upregulated miR193a-5p as a tumor suppressor, while miR193a-5p inhibitor masked the ability of Morusin to reduce the expression of ZNF746, c-Myc, and pro-PARP in HCT116 cells. To our knowledge, these findings provide the novel insight on miR193a-5p mediated inhibition of ZNF746/c-Myc signaling in Morusin induced apoptosis in CRCs.
