Rat/Mouse Obestatin RIA
Description:
Rat/Mouse Obestatin RIA
Background Information:
Obestatin is a relatively newly discovered peptide whose biological functions are not fully understood. Rat obestatin, a 23-amino acid peptide produced in the stomach, is coded by the same ghrelin gene and also derived from pre-pro-ghrelin. After differential modification, obestatin and ghrelin activate different receptors, resulting in opposite effects on appetite induction. Whereas ghrelin has an appetite-inducing effect, obestatin has been hypothesized to have an anorectic effect characterized by suppressed food intake, slower gastric emptying, inhibited jejunal motility and decreased body-weight gain. Consequently, obestatin and the ghrelin-to-obestatin ratio may play a significant role in the etiology and pathogenesis of obesity.
