HER2 is colocalised and most of the time, coamplified with the gene GRB7, which is a proto-oncogene associated with breast, testicular germ cell, gastric, and esophageal tumours. HER2 proteins have been shown to form clusters in cell membranes that may play a role in tumorigenesis. [26] [27]
The cell line is a great model for breast cancer cells because the cells proliferate at a fast rate and is stimulated by androgens, but inhibited by progesterone, estrogen, and Her-2 receptors. The specific mutation that contributes to the cell cancer line is a glutamate to histidine change found on exon 7; more specifically, the amino acid 865.
Scientists study the behaviour of isolated cells grown in the laboratory for insights into how cells function in the body in health and disease. Experiments using cell culture are used for developing new diagnostic tests and new treatments for diseases. This is a list of major breast cancer cell lines that are primarily used in breast cancer ...
All four ErbB receptor family members are nearly same in the structure having single-chain of modular glycoproteins. [4] This structure is made up of an extracellular region or ectodomain or ligand binding region that contains approximately 620 amino acids, a single transmembrane-spanning region containing approximately 23 residues, and an intracellular cytoplasmic tyrosine kinase domain ...
SkBr3 cells were derived from a pleural effusion due to an adenocarcinoma originating in a 43-year-old caucasian female. [1] The cell line over-expresses the HER2 gene product, which has been implicated in several breast cancer proliferation pathways. The SkBr3 cell line is autologous (derived from the same patient) with the AU565 cell line. [2]
"I can't put into words how I felt − anger, sadness and worry," parent Dustin Reed said about the incident at a Cracker Barrel in Waldorf, Maryland.

The HER2 gene (also known as HER2/neu and ErbB2 gene) is amplified in 20–30% of early-stage breast cancers. [44] Trastuzumab is a monoclonal antibody targeting HER2, inducing an immune-mediated response that causes internalization and recycling of HER2. It may also upregulate cell cycle inhibitors such as p21 Waf1 and p27 Kip1. [58]
