The PDGFRA gene provides instructions for making a protein called platelet-derived growth factor receptor alpha (PDGFRA), which is part of a family of proteins called receptor tyrosine kinases (RTKs). Receptor tyrosine kinases transmit signals from the cell surface into the cell through a process called signal transduction. The PDGFRA protein is found in the cell membrane of certain cell types where a specific protein, called platelet-derived growth factor, attaches (binds) to it. This binding turns on (activates) the PDGFRA protein, which then activates other proteins inside the cell by adding a cluster of oxygen and phosphorus atoms (a phosphate group) at specific positions (a process called phosphorylation). This process leads to the activation of a series of proteins in multiple signaling pathways.

The signaling pathways stimulated by the PDGFRA protein control many important cellular processes such as cell growth and division (proliferation) and cell survival. PDGFRA protein signaling is important for the development of many types of cells throughout the body.

Throat cancer
What is throat cancer. Throat cancer is a general term used to describe cancers of the throat. It is sometimes called laryngeal cancer (cancer of the larynx). It is a type of monoclonal antibody which means that it can recognise and bind to specific proteins (receptors) that are found in the cancer cellsThese proteins are epidermal growth factor.

Patient information leaflet
Breast cancer
Overall, about 7 in 10 breast cancers are oestrogen receptor positive. Treatment can block the oestrogen in these cancers (see below). Human epidermal growth factor (HER2) is a protein that can affect the growth of some cancer cells. It is found on the surface of normal breast cells. Some breast cancer cells have a very high number of HER2.

Polycythaemia rubra vera
Polycythaemia rubra vera (PRV) is a myeloproliferative disorder, which means the bone marrow makes too many blood cells. It is also sometimes just called polycythaemia (PV). There is an abnormally high number of red blood cells in your blood. You may also have an abnormally high number of platelets and white blood cells. What is normal blood made.

Peripheral vasodilators
Peripheral vasodilators are medicines that are used to treat conditions that affect blood vessels in outer (peripheral) parts of the body such as the arms and legs. For example, they are used to treat peripheral arterial disease and Raynaud's phenomenon. Cilostazol also improves circulation by keeping platelets in the blood from sticking together.

Typically, CML develops and progresses slowly - over months or years,. Who develops chronic myeloid leukaemia. CML is the rarest of the four main types of leukaemia. There are around 750 cases in the UK each year. It occurs mainly in adults and becomes more common with increasing age. The average age at diagnosis is 50 years. It is very rare in.

There are various causes. Too many platelets - this is called thrombocythaemia ( or thrombocytosis). This is due to disorders which affect cells in the bone marrow which make platelets. The FBC test provides a number of results that provide information about red and white blood cells and platelets. However haemoglobin, white blood cell and.
