They are used to research illnesses, make vaccinations, research organ systems, research hormones, produce proteins for deficient humans, make hardier, higher yielding crops and livestock, and have other possible applications. Such general uses of transgenic organisms are often widely referred to as genetic engineering. The levels of growth hormone in the serum of some of these mice were several hundred times higher than in control mice. The first step to make a transgenic organism is to make the transgene. The next step is to incorporate the transgene into a founder.
Transgenic technology has an enormous number of applications.
It is used in medical, toxicological, developmental genetic, and gene expression research. To study human diseases, transgenic animal models, usually mice, are developed to contain the disease causing gene and then studied. Cancer is one illness studied in this way. Supported by NIH WA42960. In recent research involving a number of collaborating laboratories, part of the human Huntington disease gene, including its promoter and the expanded triplet repeat sequence, was introduced into mice.
