Abstract:
BackgroundPlatelet extracellular vesicles (Plt-EVs) expressing the damage-associated molecular pattern prototypic signal, high mobility group box 1 (HMGB1), accumulate in the blood of patients with systemic sclerosis (SSc) and per se promote autoimmunity, fibrosis and vascular inflammation [1, 2]. A poorly understood defect in critical players in sprouting angiogenesis, angiopoietins and the angiopoietin receptor, TIE2 is also an hallmark of SSc. Normal neutrophils respond to angiopoietin 1 and other stimuli by undergoing activation and upregulating the Tie2 expression [3].ObjectivesWe reasone

Abstract:
CD13 (Aminopeptidase N,APN) is a glycosylated ectopeptidase with diverse physiological functions including proliferation, differentiation, migration and angiogenesis1. CD13 is a marker for neoangiogenesis that is detected in tumor neovasculature, but not in the normal vasculature, contributing with tumor growth, invasion, and metastasis. In vitro studies have revealed association between CD13 various cancer types including human glioblastoma2 and prostate3 cancers. Thus, CD13 is an appealing target for the delivery of drugs in CD13-expressing tumors which can reduce tumor growth and progressio

Abstract:
AbstractRetinopathy of prematurity (ROP) is a retinal neovascularization (RNV) disease that is characterized by abnormal blood vessel development in the retina. Importantly, the etiology of ROP remains understudied. We re‐analyzed previously published single‐cell data and discovered a strong correlation between microglia and RNV diseases, particularly ROP. Subsequently, we found that reactive oxygen species reduced autophagy‐dependent protein degradation of absent in melanoma 2 (AIM2) in hypoxic BV2 cells, leading to increased AIM2 protein accumulation. Furthermore, we engineered AIM2 knockout

Abstract:
Background: VEGFR2 (KDR/Flk1) signaling in endothelial cells (ECs) plays a central role in angiogenesis. Copper (Cu) is essential micronutrient and has been implicated in angiogenesis. The P-type ATPase transporter ATP7A is key regulator of Cu homeostasis but its role in VEGFR2 signaling in ECs and post-ischemic neovascularization is entirely unknown. Results: Here we show that ATP7A expression was dramatically increased in the angiogenic ECs in mice hindlimb ischemia model. EC-specific ATP7A deficient mice or Cu transporter-dysfunctional ATP7A mut mice showed significant decrease in blood flo

AbstractVEGFR2 (KDR/Flk1) signaling in endothelial cells (ECs) plays a central role in angiogenesis. The P-type ATPase transporter ATP7A regulates copper homeostasis, and its role in VEGFR2 signaling and angiogenesis is entirely unknown. Here, we describe the unexpected crosstalk between the Copper transporter ATP7A, autophagy, and VEGFR2 degradation. The functional significance of this Copper transporter was demonstrated by the finding that inducible EC-specific ATP7A deficient mice or ATP7A-dysfunctional ATP7Amut mice showed impaired post-ischemic neovascularization.

Abstract:
Multiterritory perforator flap is an important plastic surgery technique, yet its efficacy can be limited by partial necrosis at the choke Ⅱ zone. Butylphthalide (NBP) has been used for many diseases but has not been studied in the multiterritory perforator flap. With the effect of NBP, we observed increasing in capillary density, inhibition of autophagy and oxidative stress, and a reduction in apoptosis of cells, all consistent with increased flap survival. However, the protective effect of NBP on multiterritory perforator flap was lost following administration of the autophagy agonist rapamy

Abstract: HuR (Human antigen R) is an RNA binding protein (RBP) that specifically binds to certain RNA sequences, influencing post-transcriptional regulation. HuR is primarily involved in tumor regulation, as well as cell growth, proliferation, inflammation, and angiogenesis. HuR is implicated in endothelial activation, smooth muscle proliferation, inflammatory response, macrophage apoptosis, lipid regulation, and autophagy, playing a crucial regulatory role in atherosclerosis. Accumulating evidence suggests that HuR has dual roles in AS. On the one hand, HuR expedites the development of AS by

Abstract:
Neovascularization in the eye contributes to visual loss in several ocular diseases, including proliferative diabetic retinopathy (PDR), neovascular glaucoma (NVG) and retinopathy of prematurity (ROP). In these diseases, the neovascular mechanisms originate from the retina, but some advanced stages of PDR or nG can lead to the development of rubeosis iridis (RI), a clinical manifestation characterized by iris angiogenesis. Vascular endothelial growth factors (VEGFs) and their receptor (VEGFRs) are the key promoters of angiogenesis, playing a crucial role in both physiological and pathological
