New findings in obesity and aging research:
Weight-loss interventions improve insulin sensitivity, protect from obesity, and postpone age-associated diseases. The impact of weight-loss on stem cells and differentiation processes is little understood. Scientists of the Zwerschke Research Group at IBA recently found that weight-loss upregulates the tumor suppressor protein Sprouty1 in adipose stem cells of white adipose tissue of formerly obese people. They further showed that Sprouty1, an inhibitor of ras-MAPK signalling, acts as negative regulator of adipogenic differentiation in the adipose stem cells. This study contributes to the better understanding of obesity and stem cell aging.
