Description

Description: The monoclonal antibody 3G6 recognizes human, mouse, and rat ZEB1. ZEB1, or zinc finger E-box binding homeobox 1, is also known as Transcription Factor 8 (TCF8), Negative Regulator of IL2, and AREB6. ZEB1 acts as a transcriptional repressor that inhibits interleukin-2 (IL-2) gene expression. ZEB1 also regulates expression of the genes E-cadherin, BCL6, ATP1A1, and RCOR1 through binding to multiple enhancer boxes (E-boxes). ZEB1 promotes epithelial mesenchymal transition (EMT) and invasion of various types of cancers, such as colorectal, breast, pancreatic, lung, and gallbladder. In normal tissues, ZEB1 is expressed in tissues undergoing differentiation such as T cell and skeletal differentiation. Mutations in ZEB1 have been associated with corneal dystrophy. Applications Reported: This 3G6 antibody has been reported for use in western blotting, and immunohistochemical staining of formalin-fixed paraffin embedded tissue sections. Applications Tested: This 3G6 antibody has been tested by immunohistochemistry on formalin-fixed paraffin embedded human tissue using high pH antigen retrieval and can be used at less than or equal to 10 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 µm post-manufacturing filtered.

Experimental details

Immunofluorescence analysis of ZEB1 was performed using 70% confluent log phase MDA-MB-231 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with ZEB1 Monoclonal Antibody (3G6), eBioscience (Product # 14-9741-80) at 0.5 µg/mL dilution in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32766), (1:2000 dilution), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b: Blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing predominantly nuclear localization. Panel e represents MCF7 cells with lower expression of ZEB1 (DOI: 10.1242/jcs.084194). Panel f represents control cells with no primary antibody to assess background. The images were captured at 60x magnification.

ZEB1 directly suppresses transcription of miR-141 and miR-200c. ( A ) Schematic of the genomic organization of hsa-miR-141 and hsa-miR-200c on chromosome 12p13.31, and alignment of the highly conserved Z- and E-boxes. The putative ZEB1 binding sites, the cloned promoter and spacer sequence, as well as the region amplified for ChIP, are indicated. All numbers are relative to the start of the hsa-miR-200c stem-loop sequence. ( B ) Left panel: stable ZEB1 knockdown in the indicated undifferentiated colorectal (SW480), breast (MDA-MB231) and pancreatic (Panc-1) cell clones enhances the activity of the putative promoter, but does not or only weakly enhances the activity of the spacer sequence. The mean values of the corresponding short hairpin control (shCtl) clones were set to 1. Middle panel: overexpression of ZEB1 and to a lesser extent that of Snai1 in HCT116 cells repress the activity of the promoter but not the spacer sequence in a dose-dependant manner. The absolute transcriptional activity of the promoter was 55-fold higher than the activity of the spacer sequence. Right panel: mutations (mut) of the Z-boxes render the promoter less sensitive to suppression by ZEB1. ( C ) Electromobility shift assay using recombinant DNA-binding domain of ZEB1 (left panel) or nuclear extracts from SW480 colorectal cancer cells (right panel) and the indicated labelled probes. Mutation of the two conserved Z-boxes (Z1, Z2) strongly reduced the specific binding complex (asterisk). Three diffe
