Scientific Data Images for Human NKX3.1 Antibody

Detection of Human NKX3.1 antibody by Western Blot.

Detection of Human NKX3.1 by Western Blot.

Western blot shows lysates of LNCaP human prostate cancer cell line. PVDF Membrane was probed with 0.1 µg/mL of Goat Anti-Human NKX3.1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6080) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for NKX3.1 at approximately 38 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
NKX3 by Immunocytochemistry (ICC).1 antibody in LNCaP Human Cell Line by Immunocytochemistry (ICC).

NKX3.1 in LNCaP Human Cell Line.

NKX3.1 was detected in immersion fixed LNCaP human prostate cancer cell line using Goat Anti-Human NKX3.1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6080) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

Activation of beta-catenin pathway in LNCaP cells overexpressing delta-catenin(A) Comparison of levels of delta-catenin in overexpressing LNCaP clones and other PCa cell lines. Full length protein is depicted by arrow. (B) Levels of catenin proteins in delta-catenin overexpressing LNCaP clone (designated as OE1b) are shown. Gradient loading of total protein for OE1b clone was used to illustrate an increase in expression of each protein (right panel). Quantification graphs showing protein levels normalized to GAPDH level (arbitrary units, a.u.) are at the bottom. (C) Characterization of nuclear (NE) and cytoplasmic (CE) levels of beta-catenin. Nuclear and cytoplasmic protein was isolated, beta-catenin was detected by Western blotting using specific antibody. TBP and GAPDH were used as loading control of nuclear and cytoplasmic protein respectively. Normalized level of beta-catenin in each compartment is shown at the bottom. (D and E) Characterization of levels of proteins, downstream targets of Wnt/ beta-catenin pathway (D), and androgen regulated genes AR and NKX3.1 (E) by Western blotting. Corresponding quantification is shown. Three clones (OE3a, OR1b, OE1c) overexpressing delta-catenin at various levels were examined. Total amount of 30ug of protein was used in each experiment, unless otherwise specified (in B). SDS-PAGE and Western blot conditions as in Figure 2.

Background: NKX3.1

NKX3.1 (Homeobox protein NK-3 homolog A) is a 32-38 kDa member of the NK-3 homeobox family of transcription factors. It is expressed in testis and prostatic epithelium, and appears to be regulated by both testosterone and estrogen (but not progesterone). NKX3.1 apparently promotes prostate gland development, and acts as a tumor suppressor/transcriptional repressor by interacting with HDAC-1 and increasing p53 acetylation and half-life. Human NKX3.1 is 234 amino acids (aa) in length. It contains a DNA binding homeodomain (aa 124-183) and phosphorylation sites at Ser185 and Ser196 that regulate protein turnover. There are four splice variants that show changes N-terminal to the homeobox domain. Deletions of aa 8-56, 13-87, 15-83 and 40-83 are all reported. Over aa 1-123, human NKX3.1 shares 50% aa identity with mouse NKX3.1.
