The present study aimed to assess the role of urocortin II (UII) in the process of vascular calcification in vitro by using a calcification model, to detect the changes in the mRNA and protein levels of associated markers in rat adventitial fibroblasts (AFs) during their phenotypic transformation to osteoblast cellsto clarify the main signal transduction pathway of UII responsible for regulating vascular calcification and AF phenotypic transformation of osteoblast cells, and to prove that UII was an endogenous factor promoting vascular calcification, so as to provide an effective experimental basis for the clinical regulation of related diseases caused by vascular calcification. Finally, we successfully constructed the calcified cell model, found that UII was an endogenous substance regulating vascular calcification, regulated the vascular calcification by promoting apoptosis and inhibiting autophagy through up- and downregulated BAX and BCL-2/BECLIN 1 (BECN1) level, and the Wnt/β-catenin signaling pathway was involved.

Background: Calcification of the radial artery is one of the main causes of anastomotic stenosis in autogenous arteriovenous fistulas in uremic patients. However, the pathogenesis of calcification is still unknown. This study attempted to screen and validate the risk factors for vascular calcification in patients with uremia.

Background: Atherosclerotic calcification (AC) is a common feature of atherosclerotic cardiovascular disease. β-Hydroxybutyrate (BHB) has been identified as a molecule that influences cardiovascular disease. However, whether BHB can influence AC is still unknown.

Background: The impact of moderate-to-vigorous physical activity (MVPA) on all-cause mortality in type 2 diabetes (T2D) patients with severe abdominal aortic calcification (SAAC) remains unclear.
Methods: We analyzed data from the National Health and Nutrition Examination Survey (NHANES) 2013-2014, including T2D patients aged 40 years and older. AAC was assessed using the Kauppila scoring system, with SAAC defined as a score >6.

Aim: Microcalcification increases the vulnerability of plaques and has become an important driver of acute cardiovascular events in diabetic patients. However, the regulatory mechanisms remain unclear. DJ-1, a multifunctional protein, may play a potential role in the development of diabetic complications.
