Sulfur Dioxide Alleviates Aortic Dissection Through Inhibiting Vascular Smooth Muscle Cell Phenotype Switch, Migration, and Proliferation miR-184-3p/Cyp26b1 Axis.

Abnormal migration and proliferation of vascular smooth muscle cells (VSMCs) are considered early events in the onset of thoracic aortic dissection (TAD). Endogenous sulfur dioxide (SO), primarily produced by aspartate aminotransferase (AAT1) in mammals, has been reported to inhibit the migration and proliferation of VSMCs. However, the role of SO in the development of TAD remains unclear.

MiR-199a-5p Deficiency Promotes Artery Restenosis in Peripheral Artery Disease by Regulating ASMCs Function Targeting HIF-1α and E2F3.

Background: Restenosis (RS) poses a significant concern, leading to recurrent ischemia and the potential for amputation following intraluminal angioplasty in the treatment of Peripheral Artery Disease (PAD). Through microRNA microarray analysis, the study detected a significant downregulation of miR-199a-5p within arterial smooth muscle cells (ASMCs) associated with RS.

Objective: This research aims to explore the possible function and the underlying mechanisms of miR-199a-5p in the context of RS.

Upregulation of Long Noncoding RNA MAGOH-DT Mediates TNF-α and High Glucose-Induced Endothelial-Mesenchymal Transition in Arteriosclerosis Obliterans.

Arteriosclerosis obliterans (ASO) is characterized by arterial narrowing and blockage due to atherosclerosis, influenced by endothelial dysfunction and inflammation. This research focuses on exploring the role of MAGOH-DT, a long noncoding RNA, in mediating endothelial cell dysfunction through endothelial-mesenchymal transition (EndMT) under inflammatory and hyperglycemic stimuli, aiming to uncover potential therapeutic targets for ASO. Differential expression of lncRNAs, including MAGOH-DT, was initially identified in arterial tissues from ASO patients compared to healthy controls through lncRNA microarray analysis.

Gut microbial co-metabolite 2-methylbutyrylcarnitine exacerbates thrombosis via binding to and activating integrin α2β1.

Thrombosis represents the leading cause of death and disability upon major adverse cardiovascular events (MACEs). Numerous pathological conditions such as COVID-19 and metabolic disorders can lead to a heightened thrombotic risk; however, the underlying mechanisms remain poorly understood. Our study illustrates that 2-methylbutyrylcarnitine (2MBC), a branched-chain acylcarnitine, is accumulated in patients with COVID-19 and in patients with MACEs.

The feasibility and efficiency for constructing arteriovenous fistula with <2 mm vein-a systematic review and meta-analysis.
