cdna
▪

dna
▪

prostaglandin
▪

▪
These reports suggested that inhibition of prostaglandin synthesis was unlikely to be sole mechanism responsible for the gastric damage induced by indomethacin.
▪
Other investigators claim that endogenous prostaglandins may not be essential since gastric cytoprotection persists after pretreatment with prostaglandin synthesis inhibitors.
▪
Inhibition of prostaglandin synthesis by NSAIDs is the major established mechanism by which NSAIDs render the gastric mucosa vulnerable to mucosal injury.
▪
Another potentially useful system for laboratory study could well be the various steps in prostaglandin synthesis .
▪
Our data suggest that it is unlikely that the mechanism of this apparent synergy is enhanced depression of prostaglandin synthesis .
protein
▪
The inhibitors might therefore be causing amnesia not because they prevent protein synthesis but because of their effect on increasing amino acid levels.
▪
Addition of this phosphate group impairs the function of the essential protein , and viral protein synthesis fails to begin.
▪
But exactly how viral protein synthesis is selectively inhibited, leaving cellular protein synthesis relatively unaffected, is still not clear.
▪
Measuring the rate of protein synthesis then becomes a matter of measuring the rate at which amino acids are incorporated into proteins.
▪

▪
The increased synthesis of the metabolite is probably performed by the inflammatory cells that participate in this condition.
inhibit
