Overexpression of receptor tyrosine kinases (RTK), including members of the HER family, has prognostic and therapeutic significance in invasive esophagogastric carcinoma. RTK expression in premalignant gastroesophageal lesions has not been extensively explored. Formalin-fixed paraffin-embedded tissue samples of esophageal biopsy specimens from 73 patients with Barrett's esophagus with either lo...
چکیده مقدمه: امروزه سرطان پستان شایعترین سرطان در بین زنان و در عین حال مهمترین بیماریها در سراسر جهان میباشد. تحقیقات گستردهای در جهت پیشگیری و درمان سرطان صورت میگیرد. HER3 یکی از پروتئینهای متصل به غشا میباشد که توسط ژن ErbB3 کدگذاری میشود و تنها پس از هترودایمر شدن با دیگر اعضای خانواده میتواند فسفریله و فعال شود. هدف از این مطالعه بررسی بیانHER3 به عنوان یک فاکتور احتمالی دخیل ...
Among the four human EGF receptor (HER) family members (EGFR, HER2, HER3, HER4), HER3 is of particular interest as it interacts with HER2 and EGFR via heterodimerization and is a key link to the phosphoinositide 3-kinase (PI3K)/AKT signal transduction axis. Recent studies indicate that HER3 plays a critical role in mediating resistance to agents that target EGFR or HER2. As HER3 lacks significa...
Abstract Background Leptomeningeal disease (LMD) occurs in ~5% of patients with breast cancer (BC) and has a median survival 2-4 months. We found loss the anti-HER2 anti-HER3 CD4 Th1 immune responses BC patients. In pre-clinical clinical trials administration class II HER2 peptide-pulsed dendritic cell vaccine (HER2-DCV) partially restores pathologic complete HER2+ Here, we examined intrathecal...
Novel HER3/MUC4 oncogenic signaling aggravates the tumorigenic phenotypes of pancreatic cancer cells
Several studies have demonstrated that MUC4 is involved in progression and metastasis of pancreatic cancer (PC). Here, we report that HER3/MUC4 interaction in HER2 low cells is critical in driving pancreatic tumorigenesis. Upon HER2 knockdown, we observed elevated expression of HER3 and MUC4 and their interactions, which was confirmed by immunoprecipitation and bioinformatics analyses. In paire...
The EGFR monoclonal antibody cetuximab is the only approved targeted agent for treating head and neck squamous cell carcinoma (HNSCC). Yet resistance to cetuximab has hindered its activity in this disease. Intrinsic or compensatory HER3 signaling may contribute to cetuximab resistance. To investigate the therapeutic benefit of combining MM-121/SAR256212, an anti-HER3 monoclonal antibody, with c...
Author manuscripts have been peer reviewed and accepted for publication but have not yet been edited. Translational Relevance As a member of the EGFR receptor tyrosine kinases family, HER3 pseudo-kinase was shown to play a crucial role in regulation of oncogenic processes. Dysregulation of this receptor is associated with the progression of different human cancers including those of the breast ...
BACKGROUND HER3 (erbB-3) is a member of the epidermal growth factor receptor (EGFR) family. After dimerization with other members of the EGFR family several signal transduction cascades can be activated, including phosphoinosite 3'-kinase (PI3-K)/Akt and extracellular signal-regulated kinase (ERK1/2). Here, we studied a possible association between HER3 expression and prognosis in patients with...
HER3 (also known as c-Erb-b3) is a type I receptor tyrosine kinase similar in sequence to the epidermal growth factor (EGF) receptor. The extracellular segment of this transmembrane receptor contains four domains. Domains I and II are similar in sequence to domains III and IV, respectively, and domains II and IV are cysteine-rich. We show that the EGF-like domain of heregulin (hrg) binds to dom...
PURPOSE Tumors with oncogenic dependencies on the HER family of receptor tyrosine kinases (RTKs) often respond well to targeted inhibition. Our previous work suggested that many cell lines derived from squamous cell carcinomas of the head and neck (SCCHNs) depend on autocrine signaling driven by HER2/3 dimerization and high-level co-expression of HRG. Additionally, results from a Phase I trial ...
