The Growth Hormone Jungle

Growth hormone is a peptide hormone that stimulates growth, cell reproduction and cell regeneration in humans and other animals. As with all hormonal pathways the path concerning the promotion and secretion of growth hormone leads right into a dense jungle of interrelated secretions of life. But we must enter if we are to learn where growth transforms [...]

Fish Representatives

In most genetics research, Homo sapiens is represented by small fish like Danio rerio (zebrafish)  and Oryzias latipes (Japanese rice fish). Both are important model organisms, representing man in developmental genetics, neurophysiology and biomedicine. When we tinker with genes what happens to the fish is most likely to happen to us as well. If the [...]

Uppers & Downers

Hormones play a key role in growth as the chemical mediators with which the growth process is stimulated, or slowed down. Most hormones are controlled by a negative feedback inhibition loop. If we are to shrink the human species manipulation of this loop may represent one of the possible approaches.
Negative feedback was first implemented in mechanics [...]
