Compugen Announces In-Vivo Results for Two Novel Peptide Agonists of MAS GPCR
News Feb 13, 2008
Compugen Ltd. has announced the positive in-vivo results for two novel peptide agonists of the MAS G-protein coupled receptor (GPCR), indicating cardio-protective effects and therapeutic potential for the treatment of various cardiovascular and other pathologies.
The two peptides – CGEN-856 and CGEN-857 – were identified using the Company’s previously announced GPCR ligand discovery platform. The in-vivo results will be presented at the VII International Symposium on Vasoactive Peptides to be held February 14-16, 2008 in Brazil.
In an in-vivo model of cardiac remodeling, CGEN-856 and CGEN-857 were shown to afford significant cardio protection, as manifested by reduction of both fibrosis and hypertrophy of cardiomyocytes. Moreover, picomolar concentrations of the peptides had an anti-arrhythmogenic effect in isolated rat hearts following ischemia-reperfusion, as demonstrated by a reduction in the incidence and duration of reperfusion arrhythmias.
In addition, sub-nanomolar concentrations of these peptides demonstrated significant dose-dependant relaxation of rat aorta. Through the reduction of cardiac remodeling and a unique vasodilatatory effect, these peptides could offer a novel approach to heart failure and other cardiovascular conditions. Heart failure is a major cause of morbidity and mortality worldwide. It affects millions of people in the US and, despite continued efforts, mortality remains very high.
Unlike most cells in the rest of our body, the DNA (the genome) in each of our brain cells varies from cell to cell, caused by somatic changes. But much remains unknown, including when these changes arise, their size and locations, and whether they are random or regulated. Now, researchers have developed new techniques allowing the detection of CNVs smaller than one million base pairs.
