Obesity is a pathology characterized by an excessive accumulation of adipose tissue and it is a condition associated with complex alterations affecting different organs and systems. Obesity has great influences on cardiovascular and respiratory morbidity and mortality, and impairs the multiple aspects of metabolism. Since micro-RNAs (miRNAs) are thought to play a role in the regulation of various pathological processes, in this complex framework, the investigation of these classes of noncoding regulatory RNA seems to be promising. Selected group of obese subjects was recruited. We analyzed the expression of seven miRNAs from obese adipose tissue supposed to have a role in the pathogenesis of cardiovascular and respiratory disease related to obesity and we compared it with the expression of the same miRNAs in a group of nonobese controls. In this study what emerged is miR-27b and miR-483 significant downregulation in subcutaneous adipose tissue from obese group compared with nonobese ones. For visceral adipose tissue, a significant decrease in miR-27b and miR-223 expression was observed in obese group. Moreover, a different expression of miR-26a and miR-338 in the obese group was found. Those findings could help the individuation of previously unknown key players in the development of different diseases usually associated with obesity, such as cardiovascular and pulmonary diseases.

Abstract

Obesity is a pathology characterized by an excessive accumulation of adipose tissue and it is a condition associated with complex alterations affecting different organs and systems. Obesity has great influences on cardiovascular and respiratory morbidity and mortality, and impairs the multiple aspects of metabolism. Since micro-RNAs (miRNAs) are thought to play a role in the regulation of various pathological processes, in this complex framework, the investigation of these classes of noncoding regulatory RNA seems to be promising. Selected group of obese subjects was recruited. We analyzed the expression of seven miRNAs from obese adipose tissue supposed to have a role in the pathogenesis of cardiovascular and respiratory disease related to obesity and we compared it with the expression of the same miRNAs in a group of nonobese controls. In this study what emerged is miR-27b and miR-483 significant downregulation in subcutaneous adipose tissue from obese group compared with nonobese ones. For visceral adipose tissue, a significant decrease in miR-27b and miR-223 expression was observed in obese group. Moreover, a different expression of miR-26a and miR-338 in the obese group was found. Those findings could help the individuation of previously unknown key players in the development of different diseases usually associated with obesity, such as cardiovascular and pulmonary diseases.
