Human growth hormone increases apo(a) expression in transgenic mice.
Levels of Lp(a), an atherogenic lipoprotein that circulates in human plasma, are increased by the administration of growth hormone (GH). Many of the physiological effects of GH are mediated through insulin-like growth factor-1 (IGF-1), but ironically, IGF-1 treatment of humans is associated with a fall in plasma Lp(a) levels. To glean insight into the mechanism responsible for the GH-associated...
متن کاملTissue-specific expression and dietary regulation of a chimeric phosphoenolpyruvate carboxykinase/bovine growth hormone gene in transgenic mice.
A series of transgenic mice was produced by microinjection of a segment of DNA, containing 460 base pairs of the phosphoenolpyruvate (P-enolpyruvate) carboxykinase promoter-regulatory region ligated to the bovine growth hormone structural gene, into the male pronucleus of fertilized mouse eggs. Founder animals which contained the gene were selected for further analysis and for breeding. The con...
متن کاملTransgenic mice containing growth hormone fusion genes.
New genes composed of the mouse metallothionein I promoter-regulator and the rat or human growth hormone structural gene have been introduced into mice. A large proportion of mice containing these genes express them, and some animals grow to be up to twice as large as controls. The technique has been used in part to correct the genetic defect that results in the small stature of the mutant litt...
متن کاملEndothelial dysfunction in growth hormone transgenic mice.
Acromegaly [overproduction of GH (growth hormone)] is associated with cardiovascular disease. Transgenic mice overexpressing bGH (bovine GH) develop hypertension and hypercholesterolaemia and could be a model for cardiovascular disease in acromegaly. The aims of the present study were to investigate the effects of excess GH on vascular function and to test whether oxidative stress affects endot...
متن کاملExpression of growth hormone gene during early development of Siberian sturgeon (Acipenser baerii)
The mRNA expression of growth hormone (GH) gene in early development stages of Siberian sturgeon was investigated using RT-PCR method. Samples were collected from unfertilized eggs up to 50 days post hatched (dph) larvae in 11 different times. Ribosomal protein L6 (RPL6) transcripts were used as the internal standard during quantification of GH mRNA expression. The results showed that the GH mR...
