WebDe novo lipogenesis (DNL) in visceral adipose tissue (VAT) is associated with systemic insulin sensitivity. DNL in VAT is regulated through ChREBP activity and glucose uptake through Glut4 (encoded by Slc2a4). Slc2a4 expression, ChREBP activity, and DNL are decreased in obesity, the underlying cause however remains unidentified. We hypothesize … WebJun 1, 2016 · Resistin seems to affect insulin sensitivity in rodents (Bohler et al., 2010), and in these, there is a greater amount of it in visceral adipose tissue as opposed to its subcutaneous counterpart (ESHRE, 2006).
