Increased obese mRNA expression in omental fat cells from massively obese humans

Nature Medicine volume 1, pages 953–956 (1995)Cite this article

Abstract

Obesity presents a significant challenge to the general health of affluent nations in terms of the number of people affected, the serious associated maladies and the lack of effective treatments1–3. While common wisdom has held that obesity results from ‘gluttony and sloth’, a number of studies have indicated physiological causes underlying the pathogenesis of obesity2, with the degree of adiposity having a strong genetic component4,5. Recently, the obese gene in the ob/ob mouse was cloned, along with its human homologue6. The specific production of the obese protein by adipose tissue suggested that it may function in a feedback loop from fat tissue to the hypothalamus to control energy intake and/or energy expenditure, and that it may play a role in the pathogenesis of human obesity6–8. In this study we report that obese mRNA expression is elevated in ex vivo omental adipocytes isolated from massively obese humans in the absence of an identifiable mutation. Therefore, we speculate that this increased expression may suggest that the massively obese are insensitive to the putative regulatory function(s) of the obese gene product.
