Vascular and renal telomere shortening in mice exposed to chronic intermittent hypoxia
Obstructive sleep apnea (OSA) is a chronic condition characterized by chronic intermittent hypoxia (IH) and is associated with cardiovascular (CVD) and chronic kidney diseases (CKD). There is increased biomarkers of aging, such as telomere shortening, in patients with OSA. We assessed telomere lengths in aortic and renal tissues from mice exposed to 8 weeks of IH using a PCR protocol, and demonstrate significant telomere shortening in both tissues. This data indicates that IH, a hallmark of OSA, can accelerate vascular and renal aging that may contribute to OSA-induced CVD and CKD
