The authors found SNHG1 was upregulated in TNF-α-treated HUVECs. They silenced SNHG1 and found it inhibited vascular endothelial cell proliferation and angiogenesis.

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.

Using acute myeloid leukemia (AML) mouse models, scientists showed AML blasts released inflammatory mediators that upregulated endothelial niche E-selectin expression.
Adverum Biotechnologies, Inc. announced that the first patient was dosed in Cohort 4 of the ongoing OPTIC Phase I clinical trial for ADVM-022 for the treatment of wet age-related macular degeneration (AMD).
