Journal ArticleDOI

Expression of nitric oxide synthases in subcutaneous adipose tissue of nonobese and obese humans.

TL;DR: It is speculated that increased NO production, preferably by eNOS, and decreased HSL levels may cause decreased subcutaneous adipose tissue lipolysis in obesity.
Journal ArticleDOI

Increased fat cell size: a major phenotype of subcutaneous white adipose tissue in non-obese individuals with type 2 diabetes

TL;DR: A major phenotype of white adipose tissue in non-obese individuals with type 2 diabetes is adipocyte hypertrophy, which may be mediated by an impaired adipogenic capacity in progenitor cells, which could have an impact on adiposes tissue inflammation, release of fatty acids, ectopic fat deposition and insulin sensitivity.
Journal ArticleDOI

NF-kappaB is important for TNF-alpha-induced lipolysis in human adipocytes.

TL;DR: It is concluded that in the presence of NF-kappaB inhibition, TNF-alpha-mediated lipolysis is reduced, which suggests that NF- kappaB is essential for retained human fat celllipolysis.
Journal ArticleDOI

Evidence for a functional β3‐adrenoceptor in man

TL;DR: It is suggested that human white fat cells express an atypical β‐adrenoceptor in addition to β1‐ and β2‐ adrenoceptors and is poorly sensitive to blockade by selective β1- andβ2‐antagonists.
