Progress of the anoikis effector bcl-2 inhibitor of transcription 1 / 肿瘤研究与临床

bcl-2 inhibitor of transcription 1 (Bit1) is an anoikis effector that can play a role of caspase-independent apoptosis by down-regulating bcl-2 expression. Previous studies have found that Bit1 affects cell survival and apoptosis through Erk and FAK-PI3K-Akt-NF-κB pathways. It is worth noting that the expression of Bit1 has shown the obvious tumor specificity in different tumors, and it is closely related to TNM stage, differentiation and prognosis of the tumor. This review summarizes the expression, main mechanism, and significance of Bit1 in different tumors.
