BNIP3 overexpression

Finally, activation of incomplete mitophagy in GBM cells by DPD through BNIP3L in vivo was demonstrated by establishing a mouse subcutaneous xenograft tumor model. In this study, in vitro and in vivo experiments established that DPD inhibited GBM cell growth by inducing BNIP3L-mediated incomplete mitophagy, which provides an experimental basis for studying new treatments of GBM.

We concluded that GPAT2 expression is necessary to prevent AA-induced apoptotic cell death in MDA-MB-231 cells and that the overexpression of other AA-metabolizing genes is not sufficient to compensate for the lack of GPAT2 and prevent apoptosis.

Semaglutide ameliorates doxorubicin-induced mitochondrial and cardiac dysfunction via PI3K/AKT pathway, by reducing BNIP3 expression in mitochondria. The improvement in mitochondrial function reduces doxorubicin-mediated cardiac injury and improves cardiac function. Therefore, semaglutide is a potential therapy to reduce doxorubicin-induced acute cardiotoxicity.

Particularly, Mdivi-1 (mitophagy inhibitor) or rapamycin (an activator of autophagy) exerted the same effects on NPC cells as BNIP3 silencing or overexpression, respectively. Collectively, Parkin overexpression activated BNIP3/NIX-mediated mitochondrial autophagy to enhance sensitivity to paclitaxel in NPC.

Overexpression of BNIP3 reversed the effect of up-regulation of miR-26 expression on proliferation and apoptosis of RPMI8226 cells. Up-regulation of miR-26 expression inhibits MM cell proliferation and promotes apoptosis by targeting BNIP3.
