Meta-analysis., Data show that proto-oncogene protein HER-2 overexpression occurs in only 8% of patients with colorectal cancer (CRLM) but with 75% of cases proto-oncogene protein HER-3 is frequently overexpressed in CRLM., the EGFR and ErbB-3 heterodimerization, regarded as the origin of intracellular signaling pathways, was investigated., The aim of the study was to evaluate the prognostic ability of the transcriptional profiling of the HER family genes in early breast cancer., Dual blockade of EGFR and HER3 may enhance the targeted disruption of HER family signaling in these cancers both by blocking parallel and overlapping signaling pathways and potentially blocking the emergence of resistance., HER3/MUC4 oncogenic signaling aggravates the tumorigenic phenotypes of pancreatic cancer cells, findings show that the local 3D tumor microenvironment can trigger reprograming and switching of ErbB family members and thereby influence ErbB3-driven tumor growth, Heregulin-ErbB3-Driven Tumor Growth Persists in PI3 Kinase Mutant Cancer Cells, Expression of total HER2, total HER3 were significantly elevated in HPV(+) HNSCC., ERa-dependent expression of LRIG1 dampens ErbB3 signaling in luminal breast cancer cells, and by blocking ERa activity with fulvestrant, LRIG1 is decreased thus permitting ErbB3 accumulation, enhanced ErbB3 signaling to cell survival pathways, both ErbB-2 and ErbB-3 receptors are expressed in colon cancer stem cells and NRG-1beta plays an important role in sustaining proliferation of both wild-type and BRAF-V600E mutated cells, Data indicate that high heregulin mRNA and high HER3 protein levels are independently correlated with poor overall survival in patients with oropharyngeal squamous cell carcinoma., these studies support the rationale to target the NRG1-ErbB3-ErbB2 axis as a novel treatment strategy in a subset of cutaneous melanomas., SNP in HER2 codon 655 and investigation of HER2 and HER3 expression could be helpful to outline the prognosis for patients with lung adenocarcinoma., Findings suggest that triple therapy directed against BRAF/MEK/ErbB3 may be able to provide durable control of BRAF mutated metastatic melanoma., Data indicate that increased expression of erbB3 plays a pivotal role in activating downstream PI-3K/Akt pathway and promoting erbB2-driven mammary/breast tumorigenesis., neuregulin 1 promotes compensatory ErbB3 receptor signaling in mutant BRAF melanoma, Using a new pyrosequencing assay, this study uncovers an E332E mutation affecting HER3 in retroperitoneal leiomyosarcoma clinical samples., Data show that cotreatment with anti-ERBB3 proto-oncogene protein antibody seribantumab and letrozole had increased antitumor activity., ERBB3 Positively Correlates with Intestinal Stem Cell Markers but Marks a Distinct Non Proliferative Cell Population in Colorectal Cancer., Results demonstrate that acquired resistance of colorectal tumour cells to treatment with anti-EGFR mAb ICR62 is accompanied by an increased level of cell surface EGFR, and upregulation of phosphorylated HER-2 and HER-3 proteins., Authors show experimental evidence for an ErbB3 gain-of-function point mutation located in the C-lobe asymmetric dimerization interface, which shows enhanced phosphorylation at low ligand dose associated with increased kinase activity., critical pathophysiologic event in the evolution of HER2-amplified cancers is the loss of the input signals that normally drive TORC2 signaling, repositioning it under Akt dependency, and fundamentally altering the role of HER3, Study shows that ERBB3 is a novel regulator of beta-cell apoptosis and found rs2292239 strongly correlated with residual b-cell function and metabolic control in children with type 1 diabetes., findings newly identify a physiological function of the NRG1-ErbB2-ErbB3 axis in trophoblast survival during human placental development., BRCA1-associated DCIS did not express ER, PR or HER2, while most BRCA2-associated DCIS did express ER and PR. BRCA1- as well as BRCA2-associated DCIS had expression of HER3 and C-MET, our results suggest that HER3 over-expression may be associated with worse overall survival in gastric cancers, Data suggest that NDRG1 down-regulates expression and activation of HER1/EGFR, HER2/ERBB2, and HER3/ERBB3 in response to epidermal growth factor (EGF) ligand in pancreatic/colonic neoplasm cells., NRG1 promotes the proliferation and migration of coronary artery smooth muscle cells by enhancing the phosphorylation of ErbB2, ErbB3 and ErbB4., HER2/HER3 interaction and increased expression was linked to risk for poor outcome in lung cancer patients., ErbB3 nuclear translocation is a common event in proliferating tissues., High EGFR expression was an independent risk factor for shorter overall survival (OS), whereas high HER3 expression was associated with a borderline significant trend towards a longer OS., while transcript and protein levels of EGFR and ErbB2 were up-regulated or unaffected, respectively, hepatitis c virus induced a substantial reduction of ErbB3 and ErbB4 expression., HPV 16 E2 can modulate ErbB-3 by interacting with Nrdp-1, which is involved in the regulation of this receptor, via ubiquitination and degradation., Data indicate that clathrin-mediated endocytosis of proto-oncogene protein erbB-3 (ErbB3) is depending on epsin-1., measurements comprising the receptors EGFR, ERBB3 (HER3), and the cyclin-dependent kinase inhibitor p27 (CDKN1B) was found to accurately predict dependence on PI3K/AKT vs. MAPK/ERK signaling axes in HER2+ cancers, HER Family Protein Expression in a Greek Population with Gastric Cancer.

SP_COMMENT catalytic activity:ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate., disease:Defects in ERBB3 are the cause of lethal congenital contracture syndrome type 2 (LCCS2) [MIM:607598]; also called Israeli Bedouin multiple contracture syndrome type A. LCCS2 is an autosomal recessive neurogenic form of a neonatally lethal arthrogryposis that is associated with atrophy of the anterior horn of the spinal cord. The LCCS2 syndrome is characterized by multiple joint contractures, anterior horn atrophy in the spinal cord, and a unique feature of a markedly distended urinary bladder. The phenotype suggests a spinal cord neuropathic etiology., disease:Overexpressed in a subset of human mammary tumors., domain:The cytoplasmic part of the receptor may interact with the SH2 or SH3 domains of many signal-transducing proteins., function:Binds and is activated by neuregulins and NTAK., PTM:Ligand-binding increases phosphorylation on tyrosine residues and promotes its association with the p85 subunit of phosphatidylinositol 3-kinase., similarity:Belongs to the protein kinase superfamily. Tyr protein kinase family. EGF receptor subfamily., similarity:Contains 1 protein kinase domain., subunit:Heterodimer with each of the other ERBB receptors (Potential).
