HER2överuttryck
HER2överuttryck, also known as HER2 overexpression, refers to a condition where a specific protein called Human Epidermal growth factor Receptor 2 (HER2) is present in unusually high amounts on the surface of certain cells. This protein plays a role in cell growth and division. In some types of cancer, particularly breast cancer, HER2överuttryck can lead to more aggressive tumor growth and a poorer prognosis.
The HER2 gene provides the instructions for making the HER2 protein. When the HER2 gene is amplified
Diagnosing HER2överuttryck is crucial for guiding treatment decisions. It is typically assessed through laboratory tests performed
The identification of HER2överuttryck has revolutionized the treatment of HER2-positive cancers. Targeted therapies, such as trastuzumab
