Decreased cell adhesion promotes angiogenesis in a Pyk2-dependent manner

Decreased cell adhesion promotes angiogenesis in a Pyk2-dependent manner.

Angiogenesis is regulated by both soluble growth factors and cellular interactions with the extracellular matrix (ECM). While cell adhesion via integrins has been shown to be required for angiogenesis, the effects of quantitative changes in cell adhesion and spreading against the ECM remain less clear. Here, we show that angiogenic sprouting in natural and engineered three-dimensional matrices ...

Decreased WWOX expression promotes angiogenesis in osteosarcoma

WWOX (WW domain-containing oxidoreductase) is known to be an important tumor suppressor in cancer. In this study, we used samples from 201 osteosarcoma patients to investigate the effects of WWOX on angiogenesis and invasion. WWOX levels were negatively correlated with RUNX2 and VEGF levels, but were not correlated with OPN levels. Among the clinicopathological characteristics examined, WWOX wa...

Mouse β-defensin 14 (Defb14) promotes tumor growth by inducing angiogenesis in a CCR6-dependent manner.

β-Defensins are known for their antimicrobial activity and belong to the molecular barrier of the innate immune system against invading pathogens. In addition, it has been shown that some members of the β-defensin superfamily have the capacity to promote local innate inflammatory and systemic adaptive immune responses, mediated in part by the interaction with CCR6. We found that mouse β-defensi...

Mouse b-Defensin 14 (Defb14) Promotes Tumor Growth by Inducing Angiogenesis in a CCR6-Dependent Manner

HGF promotes adhesion of ATP-depleted renal tubular epithelial cells in a MAPK-dependent manner.

Hepatocyte growth factor (HGF) has been shown to enhance recovery from renal tubular ischemia. We investigated the possibility that HGF improves recovery by preventing ischemia-induced loss of cell adhesion. Murine inner medullary collecting duct-3 (mIMCD-3) cells subjected to 90% ATP depletion demonstrated a 55% decrease in adhesion, an effect that was completely reversed by the addition of HG...
