Myeloid ALX/FPR2 Regulates Vascularization Following Tissue Injury

Mechanistically, RNA sequencing revealed that resolvin D1 induced a transcriptional program in macrophages characteristic of a pro-revascularization phenotype. Vascularization of ischemic skeletal muscle, as well as cutaneous wounds, was impaired in mice with myeloid-specific deficiency of Alx/Fpr2, and this was associated with altered expression of pro-revascularization genes in skeletal muscle and macrophages isolated from skeletal muscle.

Euscaphic Acid and Tormentic Acid Protect Vascular Endothelial Cells against Hypoxia-Induced Apoptosis via PI3K/AKT or ERK 1/2 Signaling Pathway

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.

LncRNA OIP5-AS1 Promotes Cell Proliferation and Migration and Induces Angiogenesis via Regulating miR-3163/VEGFA in Hepatocellular Carcinoma

Scientists explored the inherent mechanism of lncRNA OIP5-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.

Endothelial E-Selectin Inhibition Improves Acute Myeloid leukemia Therapy by Disrupting Vascular Niche-Mediated Chemoresistance

Using acute myeloid leukemia (AML) mouse models, scientists showed AML blasts released inflammatory mediators that upregulated endothelial niche E-selectin expression.
