Background: Noxa

Noxa, phorbol-12-myristate-13-acetate-induced protein 1, PMA-induced protein 1, PMAIP1 (Human 6 kDa and Mouse 11.6 kDa) is a Bcl2 homology 3 (BH3) domain containing protein which plays a role in the regulation of apoptosis, specifically a pro-apoptotic role. Human Noxa contains only one BH3 domain, while the mouse and rat proteins contain two BH3 domains. The human protein is encoded by Exon 1 and 3, with Exon 2 present only in two splice variants. Human Noxa splice variants lack a BH3 domain, have no known function, and are rapidly targeted for degradation (1).

Noxa mediated apoptosis may follow its transcriptional activation by p53 as part of the DNA damage response. However, Noxa expression may be induced by HIF-1 alpha under hypoxia, promoting apoptosis independently of p53 (1). Inhibition of the anti-apoptotic Bcl2 family member Myeloid cell leukemia-1 (Mcl-1) by Noxa, leads to the activation of pro-apoptotic Bcl2 homologous antagonist killer (Bak) and Bcl2 associated X (Bax) proteins, and apoptosis through the intrinsic mitochondrial pathway (2). Other BH3 only proteins such as Bim, Puma, Bad and Bid act via the same mechanism, targeting Mcl-1 and inducing Bak/Bax mediated mitochondrial outer membrane permeabilization (MOMP), cytochrome c release and caspase 9 activation (3). Overexpression of antiapoptotic Bcl2 family members is common in various types of cancer including prostate cancer. A recent study identified antiapoptotic Bcl2 proteins involved in the development of resistance towards the androgen receptor antagonist enzalutamide, which is used for the treatment of metastatic castration-resistant prostate cancer (mCRPC) (3).
