Breast receptors
WebThe breast cancer cells have receptors (proteins) that attach to estrogen and progesterone, which helps them grow. Treatments that stop these hormones from attaching to these receptors are called hormone or endocrine therapy. Hormone therapy can reach cancer cells almost anywhere in the body and not just in the breast. WebBIOLOGY OF HER2+ BREAST CANCER. The ErbB family of receptor tyrosine kinases is comprised of four cell-surface receptors, HER1 (epidermal growth factor receptor [EGFR]), HER2, HER3, and HER4. Upon receptor dimerization an intracellular signaling cascade is activated, resulting in cell proliferation, survival, invasion, and angiogenesis (Figure 1).
