ZEB1(6935)
Expression:
P37275 ZEB1_HUMAN:

Colocalizes with SMARCA4/BRG1 in E-cadherin-negative cells from established lines, and stroma of normal colon as well as in de-differentiated epithelial cells at the invasion front of colorectal carcinomas (at protein level). Expressed in heart and skeletal muscle, but not in liver, spleen, or pancreas.

Description:
This gene encodes a zinc finger transcription factor. The encoded protein likely plays a role in transcriptional repression of interleukin 2. Mutations in this gene have been associated with posterior polymorphous corneal dystrophy-3 and late-onset Fuchs endothelial corneal dystrophy. Alternatively spliced transcript variants encoding different isoforms have been described.

Research Backgrounds

Function:

Acts as a transcriptional repressor. Inhibits interleukin-2 (IL-2) gene expression. Enhances or represses the promoter activity of the ATP1A1 gene depending on the quantity of cDNA and on the cell type. Represses E-cadherin promoter and induces an epithelial-mesenchymal transition (EMT) by recruiting SMARCA4/BRG1. Represses BCL6 transcription in the presence of the corepressor CTBP1. Positively regulates neuronal differentiation. Represses RCOR1 transcription activation during neurogenesis. Represses transcription by binding to the E box (5'-CANNTG-3'). Promotes tumorigenicity by repressing stemness-inhibiting microRNAs.

Figure 3. A549/DDP and A549/PTX cells showed molecular and morphological changes that were consistent with EMT. (A) microscopy at x200 magnification was used to assess cell morphology. The A549 cells (parental cells) had an epithelioid, rounded cobblestone appearance and there was limited formation of pseudopodia. A549/PTX and A549/DDP cells exhibited a spindle-shaped morphology and an increased formation of pseudopodia, indicating a loss of cell polarity. (B) E-cadherin, β-catenin, vimentin, MMP-2 and MMP-9 which are EMT-related proteins, were assessed in terms of expression levels. EMT-related transcription factors (Snail, Slug, Twist and ZEB1) were measured in A549/PTX and A549/DDP cells using western blot analysis. (C) The expression changes were confirmed at the mRNA level by qRT-PCR. Expression was standardized to the expression of GAPDH and normalized to 1.0 in the parental cells (compared with the parental A549 cells, means ± SEM, n=3, * P<0.05)
