Euscaphic acid protected vascular endothelial cells against hypoxia-induced apoptosis via ERK1/2 signaling pathway, and tormentic acid brought its efficacy into full play via PI3K/AKT and ERK1/2 signaling pathways.
The authors summarize how sirtuin 1 and other sirtuins may contribute to endothelial cell function and how presence of diseased conditions may alter their expressions to cause endothelial dysfunction.
The authors found SNHG1 was upregulated in TNF-α-treated HUVECs. They silenced SNHG1 and found it inhibited vascular endothelial cell proliferation and angiogenesis.

Hutchison China MediTech Limited announced that the FDA has granted two Fast Track Designations for the development of surufatinib, for the treatment of both advanced and progressive pancreatic neuroendocrine tumors (NET) and extra-pancreatic NET in patients who are not amenable for surgery.

The authors demonstrated endothelial cell involvement across vascular beds of different organs in a series of patients with COVID-19.
Researchers investigated whether S-phase kinase-associated protein-2 plays a role in the regulation of endothelial progenitor cell senescence, which is closely associated with aging-related vasculopathy.
By challenging mouse models representing different steps in VEGFA/VEGF receptor 2 (VEGFR2)-induced vascular permeability, researchers showed that targeting signaling downstream of VEGFR2 pY949 limited vascular permeability in retinopathy induced by high oxygen or by laser-wounding.
Gene Ontology (GO) analysis of far infrared radiation (FIR) up-regulated genes indicated that the pathways enriched in FIR-responsive endothelial colony forming cells were involved in cell viability, angiogenesis and transcription.
Scientists identified a critical role for NOTCH3 signaling in the differentiation of perivascular and sublining fibroblasts that expressed CD90. Using single-cell RNA sequencing and synovial tissue organoids, they found that NOTCH3 signaling drove both transcriptional and spatial gradients—emanating from vascular endothelial cells outwards—in fibroblasts.
Investigators demonstrated that mixed-lineage kinase domain-like protein (MLKL) promoted vascular inflammation by regulating the expression of adhesion molecules ICAM1, VCAM1, and E-selectin in endothelial cells.

Scientists explored the inherent mechanism of lncRNA OIP5-AS1 -AS1 in hepatocellular carcinoma (HCC). In the first place, qRT-PCR found that OIP5-AS1 and VEGFA expressions were significantly increased while miR-3163 was obviously reduced in HCC cells and tissues.
