靶點詳情

  • 功能：
    Ligand for members of the frizzled family of seven transmembrane receptors. Functions in the canonical Wnt/beta-catenin signaling pathway. Plays a redundant role in embryonic lung development.

    1. Wnt2B co-operates with Frizzled7 to mediate mesenchymal to epithelial transition in colorectal cancer. PMID: 28560804
    2. Altered WNT2B expression in bladder wall fibroblasts alters expression of the apoptosis inductor TNFSF10. PMID: 29131138
    3. we identified two independent SNPs (i.e., WNT2B rs1175649 G>T and BTRC rs61873997 G>A) that showed a predictive role in CM-specific survival, with an effect-allele-attributed hazards ratio (adjusted hazards ratio) of 1.99 (95% confidence interval = 1.41-2.81, P = 8.10 x 10(-5)) and 0.61 (0.46-0.80, 3.12x10(-4)), respectively. PMID: 28499756
    4. A549-Luc-positive cells showed cytotoxicity following exposure to the Ad-shWnt2B vector. The percentage of viable cells was significantly lower in A549-Luc cells treated with Ad-shWnt2B than with Ad-scramble (p<0.01 versus control or Ad-scramble, respectively). PMID: 27793913
    5. ACSL5 mediates antiproliferative activities via Wnt2B palmitoylation with diminished Wnt activity. The molecular pathway is probably relevant for intestinal homeostasis, overwhelmed by other pathways in carcinogenesis. PMID: 25356045
    6. these results indicate that the high-expression levels of Gli1 and Wnt2B might play a pivotal role during tumorigenesis of pancreatic cancer PMID: 25120849
    7. Results showed that miR-185-3p contributs to radioresistance of nasopharyngeal carcinoma via modulation of WNT2B expression. PMID: 25297925
    8. secretion of WNT2B and WNT9B and stabilization of beta-catenin (CTNNB1) upon virus infection negatively regulate expression of representative inducible genes IFNB1, IFIT1 and TNF in a CTNNB1-dependent effector mechanism PMID: 23785285
    9. High Wnt2B overexpression is associated with ovarian cancer metastasis and drug resistance. PMID: 22635028
    10. This is the first report on differential regulation of WNT2 and WNT2B mRNAs in human cancer cell lines. PMID: 11712082
    11. Wnt-2b mRNA is expressed in human ovarian cancer cells PMID: 12072409
    12. REVIEW: Anti-WNT2B monoclonal antibodies, WNT2B RNAi compounds, or small molecule WNT2B inhibitors could be developed as novel therapeutic agents for gastric cancer and esophageal cancer in the field of clinical oncology. PMID: 16273293
    13. in addition to alternative promoters and RNA splicing, an alternative translation start in Wnt13B and Wnt13C mRNAs increases the complexity of both human wnt13 expression and functions PMID: 16407296
    14. Heplipin induced KG-1 cell apoptosis is related with Wntl3 and ATPase3. PMID: 17649721
    15. Hedgehog signals and bHLH transcription factors are involved in WNT2B upregulation, which is counteracted by BMP, WNT and Notch signals. PMID: 19360354
