Outline of Final Research Achievements

Abnormllities in the GH1 gene, which codes growth hormone (GH), cause short stature in human. This research focus on inherited GH deficiency, and the researcher established humanized GH mice, namely, endogenous growth hormone genes in mice are exchanged into human GH1 genes in this research. In contrast to well-accepted hypothesis, this disease was turned out to be caused by totally novel mechanism. This is first in vivo study which uncovered a novel mechanism of GH deficiency.
