Zinc finger E-box binding homeobox 1 (ZEB1) is a transcription factor that promotes tumor invasion and metastasis by inducing epithelial-mesenchymal transition (EMT) in carcinoma cells. EMT not only plays an important role in embryonic development and malignant progression, but is also implicated in . Diseases associated with ZEB1 include Corneal Dystrophy, Posterior Polymorphous, 3 and Corneal Dystrophy, Fuchs Endothelial, 6.Among its related pathways are ERK Signaling and Human Embryonic Stem Cell Pluripotency.Gene Ontology (GO) annotations related to this gene include nucleic acid binding and chromatin binding
Zinc finger E-box-binding homeobox 1 is a protein that in humans is encoded by the ZEB1 gene.. ZEB1 (previously known as TCF8) encodes a zinc finger and homeodomain transcription factor that represses T-lymphocyte-specific IL2 gene expression by binding to a negative regulatory domain 100 nucleotides 5-prime of the IL2 transcription start site. ZEB1 and its mammalian paralog ZEB2 belongs to. ZEB1 regulates E-cadherin expression that is a major cell-cell adhesion protein and also known to be a tumor suppressor protein . Downregulation of E-cadherin primes to the detachment of cancer cells, increased migration, invasion, and metastasis . Because of the crucial role of ZEB1 in E-cadherin regulation, ZEB1 is considered as a. ZEB1 facilitates the epigenetic silencing of E-cadherin by recruiting multiple chromatin enzymes of E-cadherin promoter, such as histone deacetylases (HDACs), DNA methyltransferase (DNMT) and ubiquitin ligase. Destruction of the connection between ZEB1 and these chromatin-modifying enzymes may represent an efficient for treating cancer In-vitro expansion of functional adult human β-cells is an attractive approach for generating insulin-producing cells for transplantation. However, human islet cell expansion in culture results in loss of β-cell phenotype and epithelial-mesenchymal. ZEB1 and ZEB2 contain two separate zinc-finger domains and a homeodomain (1). While ZEB proteins mainly function as transcriptional suppressors, they are able to activate transcription, dependent on DNA-context and cell type (1). One of the targets suppressed by ZEB proteins is E-cadherin. Downregulation of E-cadherin is one of the hallmarks of.
All Zeb1 iΔEC mice treated with anti-PD-1 mAb survived through the observation period (200 days from tumor implantation), compared with none of the isotype control-treated Zeb1 iΔEC mice (median survival, 62 days), the isotype control-treated Zeb1 WT mice (median survival, 32 days), or the anti-PD-1-treated Zeb1 WT mice (median. . Studies in mouse models reveal that Zeb1 mediates transforming growth factor β (TGFβ)-dependent expression of smooth muscle genes and is required for.
ZEB1 protein (also known as TCF8), encoded by the ZEB1 gene in humans, is a transcription factor characterized by the presence of two C2H2-type flanking zinc finger clusters, which are responsible for interaction with paired CACCT(G) E-box-like promoter elements on DNA, and a centrally located POU-like homeodomain, not binding DNA (Vandewalle. 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 ZEB1 was directly upregulated by progesterone at the ZEB1 promoter. During preterm labor in mice, there was an upregulation of Mirn200b/Mirn429, which downregulated Zeb1 and Zeb2, resulting in derepression of transcription of the contractility-associated proteins Zeb1 is critical for tumor invasion (42-45), and at P220, it is induced on AC cells at the tumor edge as they begin to invade surrounding lung parenchyma, alveolar space, and large airways, and consistent with EMT driven by this Zeb1 induction, the epithelial specification factor E-cadherin (Cdh1) is repressed and the mesenchymal marker.
ZEB1 is predominantly expressed in CD31 hi EMCN hi bone ECs. We scanned tissues that were collected from juvenile 3-week-old mice for ZEB1 protein expression. Interestingly, we found that ZEB1, as. . Using studies of mouse cells and live mice, computational analyses, and biopsies from obese patients, Gubelmann et al. show that ZEB1.

Recently, increasing evidence suggests that diverse RNA-binding proteins (RBP) are involved in cancer process. PTBP1 is a member of RBPs that interacts with regulatory RNAs t ZEB1 A gene on chromosome 10p11.22 that encodes a zinc finger transcription factor thought to play a role in transcriptional repression of IL-2. Molecular pathology ZEB1 mutations are associated with posterior polymorphous corneal dystrophy-3 and late-onset Fuchs endothelial corneal dystrophy
ZEB1 and AP-1 factor JUN co-occupy DNA-targets in human TNBC cells. ZEB1 directly interacts with AP-1 factors JUN and FOSL1. ZEB1 mediates dual transcriptional function, being repressive on its own, but trans-activating together with AP-1 and YAP. ZEB1, AP-1 and YAP correlate with worse survival in claudin-low aggressive breast cancer Strikingly, in E15.5 Zeb1-deficient embryos (Zeb1 del/del), the most severe defect was the shortening of long bones (Figure 2A and supplementary material, Figure S2A), which we hypothesized to result from premature osteoblastic differentiation ZEB1 is a master regulator of cell state transitions (CSTs), namely epithelial to mesenchymal (EMT) or the reverse process, mesenchymal to epithelial (MET). EMT is characterized by distinct molecular and morphologic changes in which epithelial cells lose an epithelial-associated gene expression profile, apicobasal polarity and intercellular.
ZEB1 - Explore an overview of ZEB1, with a histogram displaying coding mutations, full tabulated details of all associated variants, tissue distribution and any drug resistance data Objective Understand the role of ZEB1 in the tumour initiation and progression beyond inducing an epithelial-to-mesenchymal transition. Design Expression of the transcription factor ZEB1 associates with a worse prognosis in most cancers, including colorectal carcinomas (CRCs). The study uses survival analysis, in vivo mouse transgenic and xenograft models, gene expression arrays. Results ZEB1 was induced in the colonic epithelium of UC and of mouse models of colitis. Compared with wild-type counterparts, Zeb1 -deficient mice were partially protected from experimental colitis and, in a model of inflammatory CRC, they developed fewer tumours and exhibited lower levels of DNA damage (8-oxo-dG) and higher expression of MPG ZEB1 expression and pCR. The pCR rate of patients with high ZEB1 expression was 12.8%, whereas the pCR rate of patients with negative and low ZEB1 expression was 36.1% (Fig. 2).Univariate logistic regression (OR = 0.260, 95% CI 0.082-0.829, p = 0.023) and multivariate logistic regression (OR = 0.074, 95% CI 0.011-0.475, p = 0.006) showed that low expression of ZEB1 was an independent.

Synonyms AREB6, BZP, DELTAEF1, FECD6, NIL2A, PPCD3, TCF8, ZFHEP, ZFHX1A. Because TGF-β induces Zeb1(Nishimura et al., 2006), we suggest that induction of Zeb1 is a mechanism for TGF-β repression of E-cadherin, and this is likely to occur via recruitment of a Zeb1-CtBP repressor complex to the E-cadherin promoter. In contrast to E-cadherin,vimentin expression is induced by TGF-β
Emerging studies show that long noncoding RNAs (lncRNAs) play important roles in carcinogenesis and cancer progression. The lncRNA ZEB1 antisense 1 (ZEB1-AS1) derives from the promoter region of ZEB1 and we still know little about its expressions, roles and mechanisms. RACE was used to obtain the sequence of ZEB1-AS1. RNA interference was used to decrease ZEB1-AS1 expression Epithelial to mesenchymal transition (EMT) and wound vascularization are two critical interrelated processes that enable cutaneous wound healing. Zinc finger E-box binding homeobox 1 (ZEB1), primarily studied in the context of tumor biology, is a potent EMT activator. ZEB1 is also known to contribute to endothelial cell survival as well as stimulate tumor angiogenesis ZEB1 is an important transcription factor for epithelial to mesenchymal transition (EMT) and in the regulation of cell differentiation and transformation. In the cornea, ZEB1 presents in all three layers: the epithelium, the stroma and the endothelium. Mutations of ZEB1 have been linked to multiple corneal genetic defects, particularly to the corneal dystrophies including keratoconus (KD.
ZEB1 (zinc finger E-box-binding homeobox 1), as a member in zinc finger and homeodomain transcriptional factor family, plays a key role in metastasis of some epithelial carcinomas, such as colorectal cancer, breast cancer and NSCLC. We present that ZEB1, as a vital molecular in epithelial-mesenchymal transition, could be a promising marker in. encoding different isoforms have been described. (provided by RefSeq, Mar 2010) ZEB1 (zinc finger E-box binding homeobox 1) is a protein-coding gene. Diseases associated with ZEB1 include corneal dystrophy, fuchs endothelial, 6, and corneal dystrophy, posterior polymorphous, 3 Biological context of ZEB1. The TCF8 gene encodes a zinc finger protein (Nil-2-a) . Southern hybridization and somatic cell hybrids are used to demonstrate that the murine and human genomes contain related genes for Nil-2-a. TCF8 resides on human chromosome 10 . However, there are also differences between ZEB-1 and ZEB-2, both in activity.

ZEB1 expression is associated with a poor prognosis and might be an attractive target for the treatment of ICC. Background/Aim Intrahepatic cholangiocarcinoma (ICC) is one of the most aggressive malignant tumours, so the identification of molecular targets for ICC is an important issue. Zinc finger E-box binding homeobox 1 (ZEB1) is a key. Zinc finger E‑box‑binding homeobox 1 (Zeb1) is a promoter of epithelial‑mesenchymal transformation, which may serve an important role in morbidly adherent placenta (MAP). In the present study, the protein expression levels of Zeb1 were examined in the placenta tissues of 60 patients, including 20 patients with placenta accreta (PA) and 20 patients with placenta previa without PA (UPA.

Purpose: Carcinoma cells enhance their invasive capacity through dedifferentiation and dissolution of intercellular adhesions. A key activator of this process is the ZEB1 transcription factor, which is induced in invading cancer cells by canonical Wnt signaling (β-catenin/TCF4). Tumor invasiveness also entails proteolytic remodeling of the peritumoral stroma We further demonstrated that ZEB1 is directly up-regulated by the action of progesterone (P4)/PR at the ZEB1 promoter. Excitingly, we observed that ZEB1 and ZEB2 inhibit expression of the contraction-associated genes, oxytocin receptor and connexin-43, and block oxytocin-induced contractility in human myometrial cells ZEB1 protein level is negatively regulated by the miR-200 microRNA family, which includes five members (miR-200a, -b, -c, -141, and -429). A positive feedback loop has been described with ZEB1 being able to repress miR-200c and miR-141 expression (for a review see ). The transcriptiona
Epitheliomesenchymal transition (EMT) is the process where cancer cells attain fibroblastic features and are thus able to invade neighboring tissues. Transcriptional factors zeb1, snai1 and twist regulate EMT. We used immunohistochemistry to investigate the expression of zeb1, twist and snai1 in tumor and stromal compartments by in a large set of breast carcinomas ZEB1 (zinc finger E-box binding homeobox 1) Non-annotated gene.

ZEB1-mediated resistance requires ZEB1-suppresion of miR-200c, partially requires NOTCH1 expression, and is associated with EMT. Furthermore, the authors demonstrate that gefitinib resistance can be partially overcome with γ-secretase inhibitors, providing evidence for use of inhibitors of the NOTCH1 signaling pathway in the setting of EGFRi. Together with our demonstration in BrCa cell lines that ZEB1 is the driver of the de novo generation of CSCs from non-CSC cell populations, the high expression of ZEB1 in TN BrCa cells raises the possibility that the more aggressive nature of clinical TN-type BrCa compared to luminal-type BrCa may be in part attributable to the ability of TN.
Finally, ZEB1 siRNA rescued the DDR1 downregulation and mechanical allodynia induced by oxaliplatin. In conclusion, these results suggested that the ZEB1 recruited DNMT3b to the Ddr1 promoter, which induced the DDR1 downregulation and contributed to the oxaliplatin-induced chronic pain ZEB1 has intrinsic oncogenic functions that control the epithelial-to-mesenchymal transition (EMT) of cancer cells, impacting tumorigenesis from its earliest stages. By integrating microenvironment signals and being implicated in feedback regulatory loops, ZEB1 appears to be a central switch that determines EMT and metastasis of cancer cells Symbol: ZEB1 .

Os-teosarcoma mainly derives from mesenchymal tissues, and is frequently occurred in childre Expression of ZEB1 (AREB6, BZP, FECD6, NIL-2-A, PPCD3, TCF8, ZEB, Zfhep, Zfhx1a) in adipose tissue tissue. Antibody staining with HPA027524 and CAB058686 in immunohistochemistry ZEB1 upregulation in lung cancer could be controlled by cyclooxygenase-2 . The expression level of E-cadherin and ZEB1 is a useful indicator of cancer cell sensitive to target therapy including epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors, gefitinib, and erlotinib Zeb1 is expressed in the mesenchyme but not the epithelium during palatal shelf outgrowth (Liu et al., 2008; Shin et al., 2012). Zeb1 −/− palatal mesenchyme fails to express the mesenchymal marker vimentin but ectopically expresses the epithelial marker E-cadherin at E16.5 (Liu et al., 2016)
Zeb1 inhibits the in vivo induction of atrogenes upon immobilization. (A) Wild-type and Zeb1 (+/-) mice were subjected to unilateral hindlimb immobilization during 3 and 17 days and their immobilized and non-immobilized gastrocnemius were then examined for Fbxo32 mRNA expression by qRT-PCR with respect to Gapdh.Fbxo32 mRNA levels in the non-immobilized hindlimb at day 0 were arbitrarily set to. Zeb1 was a target of miR-200b involved in the protective role of TSC exosomes. Previous studies revealed that Zeb1 was a downstream target of miR-200b and exerted an antiapoptotic effect. Therefore, we examined Zeb1 expression in the abovementioned groups JASPAR is an open-access database of curated, non-redundant transcription factor (TF) binding profiles stored as position frequency matrices (PFMs) and TF flexible models (TFFMs) for TFs across multiple species in six taxonomic groups.

This is a Validated Antibody Database (VAD) review about human ZEB1, based on 65 published articles (read how Labome selects the articles), using ZEB1 antibody in all methods.It is aimed to help Labome visitors find the most suited ZEB1 antibody. Please note the number of articles fluctuates since newly identified citations are added and citations for discontinued catalog numbers are removed. ZEB1 expression in TE and MP subsets was examined using Western blot on protein lysates from LCMV-specific CD8+ T cells, and this confirmed MP cells contain more ZEB1 compared with the TE cells (Fig. 1 c). These data demonstrate that during an immune response, Zeb1 and Zeb2 are expressed in a reciproca
Importantly, expression of EMT activator Zeb1 was increased in IL-1β-induced spheres, indicating that there might be a close association between EMT and IL-1β-induced CSC self-renewal. Indeed, IL-1β treatment led to EMT of colon cancer cells with loss of E-cadherin, up-regulation of Zeb1, and gain of the mesenchymal phenotype The expression of miR-484 and SMAD2/ZEB1 in the tissues and cell lines demonstrated that miR-484 had negative correlation with SMAD2/ZEB1, and that SMAD2 had positive correlation with ZEB1 (Fig. 9b, c). This result further supported that SMAD2 is an upstream protein of ZEB1 and they are both regulated by miR-484 ZEB1 expression was raised in MYBsh-LA cells and significantly repressed in MYB-overexpressing MDA-MB-231 cells, which also showed reduced random migration and a shift from mesenchymal to epithelial colony morphology in two dimensional monolayer cultures. Finally, we detected binding of ZEB1 to MYB promoter in PMC42-ET cells, and ZEB1. But, Rb1 repression of Zeb1 provides the major impact of Rb1 on Ets1 expression. We link Rb1 repression of Zeb1 to induction of miR-200 family members, which in turn target Ets1 mRNA. These findings suggest that Ets1 and Zeb1 comprise an amplification loop that is dependent upon miR-200 and regulated by Rb1 ZEB1 is a zinc finger transcription factor located on human chromosome 10p11.22 and one of the most essential regulators during MET. 24 ZEB1 plays an important role in cancer metastasis. 25 ZEB1 overexpression induces the metastasis and invasion of OS. 26 By combining the results of previous and current studies, 14 we proposed that ZEB1 may be.

Mechanistically, SNHG3 knockdown suppressed cell proliferation and invasion by upregulation of miR-101 and downregulation of ZEB1 expression in breast cancer cells in vitro and in vivo ZEB1 and ZEB2 protein levels, but not mRNA levels, were decreased by knockdown of lncRNA XIST, and this decrease was abolished by inhibition of miR-200b-3p (Figure 4e and 4f). These data demonstrated that the regulation of ZEB1/2 by lncRNA XIST was dependent on the specific binding of miR-200b-3p As we know, Snail, Slug, ZEB1/2, and Twist are important upstream transcription regulators of EMT [12,13,14]. However, only ZEB1 expression decreased or increased with overexpression or silencing of ABCA8, respectively (Fig. 4d). This result was confirmed by qPCR (Additional file 6: Figure S5). To clarify the molecular mechanism by which ABCA8.
