WebMammalian telomeres are guanine-rich sequences which cap the ends of linear chromosomes. While recognized as sites sensitive to oxidative stress, studies on the consequences of oxidative damage to telomeres have been primarily limited to experimental conditions which cause oxidative damage throughou … WebThe naked mole rat (NMR), a long-lived and cancer-resistant rodent, is highly resistant to hypoxia. Here, using robust cellular models wherein the mouse telomeric protein TRF1 is substituted by NMR TRF1 or its mutant forms, we show that TRF1 supports maximal glycolytic capacity under low oxygen, shows increased nuclear localization and … WebTelomeric Repeat Factor 1 (TRF1) is a protein that binds at telomere ends. To measure the concentrations of TRF1 and the relationships among telomere length, telomerase activity, … switch my wig make him feel like he cheating
