Modulation of early human preadipocyte differentiation by glucocorticoids.
Glucocorticoids provide an adipogenic stimulus that is most obvious in the truncal obesity of patients with Cushing's syndrome. Glucocorticoid treatment also strongly potentiates the differentiation of human preadipocytes in culture. However, the molecular basis of these stimulatory effects remains to be defined. In this study, we provide a detailed analysis of the specific contribution of gluc...
متن کاملModulation of the human preadipocyte mitochondrial activity by beta-carotene.
Increased ROS generation by the overload by metabolic substrates mitochondria paralleled by decrease of antioxidant activity are typical events found in metabolic syndrome and diabetes type 2. Metabolites of beta-carotene (BC) such as retinoic acid (RA), as well as low concentration of reactive oxygen species (ROS) modify the mitochondrial bioenergetic function. The aim of the study was to inve...
متن کاملA human adenovirus enhances preadipocyte differentiation.
OBJECTIVE Adenovirus 36 (Ad-36) has been shown to increase adiposity in experimentally infected chickens, mice, and marmosets (nonhuman primates). Neutralizing antibodies to Ad-36 are associated with obesity in humans. The metabolic and molecular mechanisms responsible for Ad-36-induced adipogenesis are unknown. As a potential adipogenic mechanism, this study examined if Ad-36 enhanced differen...
متن کاملImpaired Preadipocyte Differentiation in Human Abdominal Obesity
OBJECTIVE We examined preadipocyte differentiation in obese and nonobese individuals and the effect of cytokines and wingless-type MMTV (mouse mammary tumor virus) integration site family, member 3A (Wnt3a) protein on preadipocyte differentiation and phenotype. RESEARCH DESIGN AND METHODS Abdominal subcutaneous adipose tissue biopsies were obtained from a total of 51 donors with varying BMI. ...
متن کاملSecretion of plasminogen activator by human polymorphonuclear leukocytes. Modulation by glucocorticoids and other effectors
Purified human PMNs secrete plasminogen activator. This secretion is stimulated by Con A and low concentrations of PMA, and is inhibited by low concentrations of glucocorticoids, and by cAMP, actinomycin D, and cycloheximide. In contrast, the release of granule-bound enzymes, such as elastase, is achieved only at higher concentrations of PMA, and is not affected by any of the inhibitors that bl...
