Depletion of the TRF1 telomere-binding protein leads to leaner mice with altered metabolic profiles

TRF1, a component of the telomere shelterin complex, plays crucial roles in telomere protection, telomere length regulation, and stemness. Here, we describe a previously unknown connection between TRF1 and metabolism. Telomere attrition has been linked to obesity. Our study reveals that Trf1-deficie...

Sumario:TRF1, a component of the telomere shelterin complex, plays crucial roles in telomere protection, telomere length regulation, and stemness. Here, we describe a previously unknown connection between TRF1 and metabolism. Telomere attrition has been linked to obesity. Our study reveals that Trf1-deficient mice exhibit a leaner phenotype, reduced adiposity, and improved glucose tolerance, even when subjected to a high-fat diet, independently of telomere shortening. These findings uncover a previously unknown role of TRF1 in regulating metabolism
