Abstract

This study investigated the mechanistic intersection between aging, diabetes mellitus (DM), and prelamin A accumulation in vascular calcification (VC) progression in patients with peripheral arterial disease (PAD) undergoing lower limb amputation. Arterial segments were collected from amputated PAD patients with (PAD + DM, n = 10) and without DM (PAD, n = 8), as well as from non-vascular amputated patients (CTRL, n = 3). Additional in vivo and

Research summary

The paper claims that prelamin A accumulation regulates vascular smooth muscle cell mineralization in the context of diabetes mellitus and vascular calcification. This study is relevant as it explores the mechanistic links between aging-related processes, diabetes, and vascular health, potentially addressing underlying causes of age-related vascular diseases.
