- Description
- Description: The Notch family of transmembrane receptors controls cell-fate decisions during the development of many organs in a wide variety of species. After binding its ligand, the Notch receptor is cleaved in its transmembrane domain, and the resulting intracellular domain dissociates from the membrane and translocates to the nucleus, where it is able to suppress the expression of lineage-specific genes by interacting with transcriptional repressors. The mN1A antibody reacts with the intracellular domain of mouse and human Notch1, but not with Notch2, 3, or 4. The mN1A antibody has a low affinity for the full-length (unprocessed or heterodimeric cell surface) forms of Notch1. In the mouse, Notch mRNA is expressed in mouse hematopoietic cells of the fetal liver and adult thymus and bone marrow. In the thymus, Notch1 protein is detected in CD4-CD8- (double-negative) and CD4-CD8+ (single-positive) thymocytes. Studies of Notch1-transgenic cells and Notch1-null mice indicate that the receptor is involved in the regulation of lymphopoiesis and myelopoiesis.

- Western blot was performed using Anti-NOTCH1 Monoclonal Antibody (mN1A), eBioscience™ (Product # 14-5785-81) and a 110 kDa band corresponding to NOTCH1 was observed across in MCF 10A and MOLT-4 in comparison to MDA-MB-231, MCF-7 and Jurkat which are reported to be negative . Whole cell extracts (30 µg lysate) of MCF 10A (Lane 1), MDA-MB-231 (Lane 2), MCF-7 (Lane 3), MOLT-4 (Lane 4) and Jurkat (Lane 5) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). Resolved proteins were then transferred onto a Nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:500 dilution) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

- Knockout of NOTCH1 was achieved by CRISPR-Cas9 genome editing using LentiArray™ Lentiviral sgRNA (Product # A32042, Assay ID CRISPR682588_LV) and LentiArray Cas9 Lentivirus (Product # A32064). Western blot analysis of NOTCH1 was performed by loading 50 µg of MDA-MB-231 wild type (Lane 1) and MDA-MB-231 NOTCH1 KO (Lane 2) whole cell extracts. The samples were electrophoresed using NuPAGE™ 3-8% Tris-Acetate Protein Gel (Product # EA0378BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with Anti-NOTCH1 Monoclonal Antibody (mN1A), eBioscience™ (Product # 14-5785-81, 1:500 dilution) and Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using SuperSignal™ West Dura Extended Duration Substrate (Product # 34076). Loss of signal upon CRISPR mediated knockout (KO) using the LentiArray™ CRISPR product line confirms that antibody is specific to NOTCH1.

- Figure 4 Expression of NOTCH1 NICD and NOTCH-specific target gene HES1 in melanoma cell lines. (A) mRNA of NOTCH1 NICD and HES1 was measured by RT-qPCR in NHEM, WM35 and A375 and A2058 melanoma cells. Melanocytes served as the control. WM35 showed a higher level of NOTCH1 NICD mRNA and HES1 mRNA than A375 and A2058 cells. (B) Protein level of NOTCH1 NICD and HES1 was measured by western blot analysis in WM35, A375 and A2058 melanoma cell lines. All of the melanoma cell lines positively expressed NOTCH1 NICD and HES1. (B-D) Effect of TGFbeta-1 treatment on NOTCH1 NICD , HES1 mRNA and protein levels in melanoma cell lines. Treatment with rhTGF-beta1 (5 ng/ml) for 48 h induced a higher increase of NOTCH1 NICD and HES1 mRNA and their own protein levels in WM35, A375 and A2058 melanoma cells. As an internal control, GAPDH was used for normalization. Data are shown as mean +- SD of three independent experiments. The comparison of mRNA NOTCH-1 and HES1 expression in multiple groups was performed by ANOVA and Tukey's test. HES1, hairy and enhancer of split 1; RT-qPCR, reverse transcription-quantitative polymerase chain reaction; TGF-beta, transforming growth factor-beta; rh, recombinant human; GAPDH, glyceraldehyde 3-phosphate dehydrogenase. ** P

- Figure 5 GSI effect on NOTCH1 NICD , NOTCH-specific target gene HES1 expression and on TGF-beta/Smad signaling in melanoma cell lines. (A) Inhibition of NOTCH1 NICD and NOTCH-specific target gene HES1 is illustrated after 72 h of 20 mu M GSI treatment in WM35, A375 and A2058 cells. Western blot analysis showed that GSI suppressed NOTCH1 NICD and HES1 protein levels and downregulated TGFbeta-1- induced NOTCH1 NICD , HES1 protein levels in melanoma cell lines. (B) GSI treatment consistently decreased pSMAD3 levels in all melanoma cell lines. GAPDH served as loading control. GSI, gamma-secretase inhibitor; HES1, hairy and enhancer of split 1; TGF-beta, transforming growth factor-beta; pSMAD3, phosphorylated Smad3; GAPDH, glyceraldehyde 3-phosphate dehydrogenase.
