Proteinuria: Excess protein in the urine. Some
protein is normal
in the urine. Too much means protein is leaking through the kidney,
most often through
the glomeruli. The main protein in human blood
and the key to the regulation of the osmotic pressure of blood is
Proteinuria is synonym...
Proteolipid protein: Abbreviation: PLP. Also called lipophilin. The most abundant protein of myelin, the covering and insulation around nerves. The gene PLP1 that codes for PLP is on the X chromosome.
Mutations in PLP cause Pelizaeus-Merzbacher disease (PMD), an X-linked recessive disorder characte...
Proteome: The complete set of proteins expressed and modified following their expression by the genome. The term "proteome" was coined from the PROTEin complement of the genOME in 1994 by Marc Wilkins, a graduate student at Macquarie University in Australia.
The analysis of the proteome is proteomi...
Proteomics: The study of the proteome, the complete set of proteins produced by a species, using the technologies of large-scale protein separation and identification. The term proteomics was coined in 1994 by Marc Wilkins who defined it as "the study of proteins, how they're modified, when and wher...
Proteus syndrome: A disturbance of cell growth including benign
tumors under the skin, overgrowth of the body, often more on one side than the other
(hemihypertrophy), and overgrowth of fingers (macrodactyly). The syndrome is named after
the Greek god Proteus the polymorphous who could change his ap...
Prothrombin: A coagulation (clotting) factor that is needed for the normal clotting of blood. A cascade of biochemical events leads to the formation of the final clot. In this cascade, prothrombin is a precursor to thrombin.
Prothrombin is also known as thrombinogen and, in medical jargon, as pro. ...

Prothrombin mutation G20210A
Prothrombin mutation G20210A: A common genetic risk factor for thrombosis (clots) including deep venous thrombosis (DVT). This mutation in the gene encoding the clotting factor prothrombin is found in about 1 in 50 persons in the US. It raises the risk of thrombosis significantly for both males and ...
Prothrombin time: A clotting test, the prothrombin time is done to test the integrity of part of the clotting scheme. The prothrombin time is commonly used as a method of monitoring the accuracy of blood thinning treatment (anticoagulation) with warfarin (Coumadin). Familiarly called the "pro time,"...
Proto-oncogene: A normal gene which, when altered by mutation, becomes an oncogene that can contribute to cancer. Proto-oncogenes may have many different functions in the cell. Some proto-oncogenes provide signals that lead to cell division. Other proto-oncogenes regulate programmed cell death (apop...

Protozoa: A single-cell organism that can only divide within a
host organism. Malaria is caused by a protozoa: Plasmodium. Other protozoan parasites
Giardia and Toxoplasma. ...
