Scientific Data Images for Noxa Antibody

Western Blot: Noxa Antibody [NB100-56368]

Western Blot: Noxa Antibody [NB100-56368]

Western Blot: Noxa Antibody [NB100-56368] - Noxa expression was stably reduced in HCT116 cells by shRNA. Western blot image submitted by a verified customer review.
Immunohistochemistry-Paraffin: Noxa Antibody [NB100-56368]

Immunohistochemistry-Paraffin: Noxa Antibody [NB100-56368]

Immunohistochemistry-Paraffin: Noxa Antibody [NB100-56368] - IHC analysis of formalin fixed paraffin-embedded (FFPE) human tonsil using Noxa antibody at 1:50 on a Bond Rx autostainer (Leica Biosystems). The assay involved 20 minutes of heat induced antigen retrieval (HIER) using 10 mM sodium citrate buffer (pH 6.0) and endogenous peroxidase quenching with peroxide block. The sections were incubated with primary antibody for 30 minutes and Bond Polymer Refine Detection (Leica Biosystems) with DAB was used for signal development followed by counterstaining with hematoxylin. Whole slide scanning and capturing of representative images was performed using Aperio AT2 (Leica Biosystems). Staining was performed by Histowiz.
Immunocytochemistry/ Immunofluorescence: Noxa Antibody [NB100-56368]

Immunocytochemistry/ Immunofluorescence: Noxa Antibody [NB100-56368]

Immunocytochemistry/Immunofluorescence: Noxa Antibody [NB100-56368] - HeLa cells were fixed for 10 minutes using 10% formalin and then permeabilized for 5 minutes using 1X TBS + 0.5% Triton X-100. The cells were incubated with anti-Noxa (NB100-56368) antibody at a 1:200 dilution overnight at 4C and detected with an anti-rabbit DyLight 488 (Green) at a 1:500 dilution. Alpha tubulin was used as a co-stain at a 1:1000 dilution and detected with an anti-mouse DyLight 550 (Red) at a 1:500 dilution. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 40X objective.

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).
