An enzyme that is involved in the control of blood coagulation and fibrinolysis.  

Two viruses identified (so far) which cause acquired immune deficiency syndrome (AIDS). HIV-1 and HIV-2 show a preferential tropism (affinity) toward the helper T cells, although other immune system (and nervous system) cells are also infected. The GP120 envelope (surface) protein of HIV-1 and HIV-2 directly interacts (binds) with the CD4 proteins (receptors) on the…

A glycoprotein that is thought to possess a different oligosaccharide when it is produced by a (liver) tumor cell instead of a healthy cell. Thus, it is a possible early warning marker for liver cancer.  

A gene that appears to be directly related to human breast cancer mortality. The more copies of the HER-2 gene (in a patient’s breast tumor cells) the more dismal that patient’s prospects for survival.  

A second generation tissue plasminogen activator (tPA), which has the clot-sensitive activation of plasminogen with potentially greater selectivity and (clot) specificity.  

A human hormone. In 1986, Mark Bogart discovered that elevated levels of human chorionic gonadotropin in pregnant women are correlated with babies (later) born with Down Syndrome. Hormones produced by the placenta and detected in the urine and blood of a pregnant woman. The gonad stimulating hormone from the embryo. A hormone produced by the…

Chromosomes that have been synthesized (made) from chemicals that are identical to chromosomes within human cells.  

Sites in genes at which events, such as mutations, occur with unusually high frequency. An area on the surface of the skin that, when stimulated, causes a sensation of warmth. In the context of therapy technologists, the term “overlying treatment areas by two portal openings” is used to describe the process of exposing two portal…

The host is the organism into which a gene from another organism is transplanted. The guest gene is carried by a vector (i.e., a larger DNA molecule, such as a plasmid, or a virus into which that gene is inserted) which then propagates in the host.  

A cell whose metabolism is used for growth and reproduction by a virus. Also the cell into which a plasmid is introduced (in recombinant DNA experiments).
