HER2 activation results from heterodimerization with another ERBB member or by homodimerization when HER2 concentration are high, for instance in cancer. [8] Amplification or over-expression of this oncogene has been shown to play an important role in the development and progression of certain aggressive types of breast cancer.
EGFR signaling cascades Diagram of the EGF receptor highlighting important domains. Epidermal growth factor receptor (EGFR) is a transmembrane protein that is activated by binding of its specific ligands, including epidermal growth factor and transforming growth factor alpha (TGF-α). [7]
The Organizational-Activational Hypothesis states that steroid hormones permanently organize the nervous system during early development, which is reflected in adult male or female typical behaviors. [1] In adulthood, the same steroid hormones activate, modulate, and inhibit these behaviors.
HERC2 is a giant E3 ubiquitin protein ligase, implicated in DNA repair regulation, pigmentation and neurological disorders.It is encoded by a gene of the same name belonging to the HERC family, which typically encodes large protein products with C-terminal HECT domains and one or more RCC1-like (RLD) domains.
The main approach in overcoming endocrine resistance in those breast cancers that are both ER+ and HER2+ is by using a combination of endocrine and HER2-targeting agents. [22] In trials conducted with a combination of anti-HER2 agents and an aromatase inhibitor, significant clinical benefit and improved progression-free survival have been observed.
The chromosome theory of cancer is a long-standing idea originated from the work of Theodor Boveri, a German biologist, in the early 20th century. Boveri's studies on sea urchin eggs provided early evidence that abnormal chromosome numbers could lead to developmental defects, leading him to propose a connection between chromosomal abnormalities ...

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]
