ERBB is abbreviated from erythroblastic oncogene B, a gene originally isolated from the avian genome. The human protein is also frequently referred to as HER2 (human epidermal growth factor receptor 2) or CD340 (cluster of differentiation 340). [5] [6] [7] HER2 is a member of the human epidermal growth factor receptor (HER/EGFR/ERBB) family ...
The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR (ErbB-1), HER2/neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). In many cancer types, mutations affecting EGFR expression or activity could result in cancer. [6]
The human ERBB3 gene is located on the long arm of chromosome 12 (12q13). It is encoded by 23,651 base pairs and translates into 1342 amino acids. [5]During human development, ERBB3 is expressed in skin, bone, muscle, nervous system, heart, lungs, and intestinal epithelium. [6]
neuregulin-2 (NRG2) neuregulin-3 (NRG3) neuregulin-4 (NRG4). All family members contain one or more repeats of the conserved amino acid sequence: CX 7 CX 4-5 CX 10-13 CXCX 8 GXRC. Where C is cysteine, G is glycine, R is arginine, and X represents any amino acid. [16] This sequence contains six cysteine residues that form three intramolecular ...
Trastuzumab downregulates neuregulin-1 (NRG-1), which is essential for the activation of cell survival pathways in cardiomyocytes and the maintenance of cardiac function. NRG-1 activates the MAPK pathway and the PI3K/AKT pathway as well as focal adhesion kinases (FAK). These are all significant for the function and structure of cardiomyocytes.
December 7, 2024 at 1:32 AM Catherine, Princess of Wales, offered a rare reflection on her cancer journey during an interaction at her annual carol service, “Together At Christmas.”
Well, that’s exactly what the winning head coach of the annual Duke’s Mayo Bowl receives as a “reward” for winning the game at Bank of America Stadium, a tradition born in 2021 as Duke’s ...
[4] [5] [6] The ability of FXII to bind to negatively charged surfaces and activate coagulation forms the basis of the aPTT test, in which artificial materials act as a surface for contact activation. This test is used to measure the contact activation pathway (intrinsic pathway) and the common pathway of clotting. [7]
