If has been proposed that a spontaneous deletion in the nicotinamide nucleotide transhydrogenase (Nnt) gene eliminating exons 7-11 in C57BL/6J (B6J) mice is associated with reduced glucose-stimulated insulin secretion in vitro, impaired glucose tolerance, higher epigonadal fat mass and altered susceptibility to diet induced obesity (DIO) of male B6J mice. A potential implication for NNT in human adipose tissue distribution has not been investigated so far. We therefore analyzed NNT mRNA expression in paired human samples of visceral (vis) and subcutaneous (sc) adipose tissue from 221 subjects with a wide range of BMI, insulin sensitivity and glucose tolerance.
NNT mRNA expression is significantly higher in visceral fat of obese patients and correlates with body weight, BMI, % body fat, visceral and sc fat area, waist and hip circumference as well fasting plasma insulin. Multivariate linear regression analysis revealed visceral fat area, and % body fat, but not fasting plasma insulin and 2h OGTT glucose. In conclusion, our data suggest a functional relevance of NNT in the development of human obesity and visceral fat distribution.
