Article Abstract
In the previous report, Meox1 was found to promote SMCs phenotypic modulation and injury-induced vascular remodeling by regulating the FAK-ERK1/2-autophagy signaling cascade (Wu et al., 2017) [1]. Here, we presented new original data on the involvement of Mesoderm/mesenchyme homeobox gene l (Meox1) in balloon-injury-induced neointima formation of rat. In rat carotid artery balloon injury model to induce vascular remodeling, Meox1 was induced in vascular smooth muscle cell (SMCs) of rat carotid arteries. Most proliferating cell nuclear antigen (PCNA)-positive cells also expressed Meox1. These data suggested that Meox1 may be involved in SMCs proliferation during injury-induced neointima formation. Furthermore, knocked down its expression in injured arteries by adenoviral delivery of Meox1 short hairpin RNA (shRNA) (shMeox1), neointima formation was significantly inhibited. Elastin staining also confirmed the reduction of neointima in Meox1 shRNA-transduced arteries. Moreover, knockdown of Meox1 decreased the collagen production/deposition that was significantly increased in neointima induced by balloon injury.

Restenosis following endovascular intervention in lower extremity arterial disease contributes to significant morbidity and mortality. This study investigates the role of formylpeptide receptor 2 (FPR2) in neointimal hyperplasia and evaluates the therapeutic potential of the selective FPR2 agonist BMS-986235 in mitigating restenosis. FPR2 expression was significantly reduced in the popliteal and anterior tibial arteries of male amputees with restenosis compared to healthy controls.

Pathological vascular remodeling and intimal hyperplasia after vascular injury are representative pathological processes in age-associated vascular diseases. Previous data from our laboratory have indicated that sterol regulatory element-binding protein (SREBP) cleavage-activating protein (SCAP) contributes to physiological angiogenesis during embryonic development. However, the role of SCAP in neointima formation is not fully understood.

As a widely used vascular access for hemodialysis patients, arteriovenous fistula (AVF) still faces high failure rates, in which local inflammatory response is an essential factor. In animal studies, chronic kidney disease (CKD) has been reported to aggravate local inflammation in AVFs, but the mechanisms are controversial. Here, spatial transcriptomics and single-cell RNA sequencing are used to explore the cellular changes during AVF remodeling in human and mouse.

Background: Whereas antiphospholipid syndrome (APS) is best known for increasing the risk of macrovascular thrombosis, APS vasculopathy is characterized by the abnormal proliferation of endothelial and smooth muscle cells, leading to occlusion of small blood vessels in the skin, kidneys, and heart, among other organs. The underlying mechanisms remain unclear, and targeted treatment options for patients with APS are lacking.
Methods: To identify and analyze APS microvascular endothelial cells (MVECs), skin biopsies of patients with APS complicated by livedo racemosa were characterized using single-cell RNA sequencing.

Background And Aims: Neointimal hyperplasia is a key pathology in Type 2 Diabetes Mellitus (T2DM) vascular complications. It involves phenotypic switching of vascular smooth muscle cells (VSMCs) triggered by hyperglycemia, though the exact mechanisms remain unclear.
Methods: We employed Twist1 vascular smooth muscle-specific knockout mice with carotid artery ligation in a T2DM model to study Twist1's role in diabetic neointimal hyperplasia.
