WebHIF-1 can initiate hypoxia mediated apoptosis by increasing the expression of Bcl-2 binding proteins—BNIP3 and NIX—thereby inhibiting the antiapoptotic effect of Bcl-2. A different mechanism of inducing apoptosis is by stabilisation of wild-type p53 by HIF-1. If the cell already has a p53 gene mutation, hypoxia induced apoptosis is prevented. sims 4 create a sim freeWebTwo sequence motifs from HIF-1 bind to the DNA-binding site of p53 Lars O.
