Gastric cancer cell-derived extracellular vesicles disrupt endothelial integrity and promote metastasis.

The endothelium is the critical barrier that controls transendothelial communications. Blood vessels in cancer tissue are poorly developed and highly permeable. However, it is poorly understood how circulating cancer cells released through these "leaky" vessels break the intact vasculature of remote organs to metastasize.

PARP1 as a prognostic biomarker for human cancers: a meta-analysis.

A comprehensive meta-analysis was carried out to evaluate the association between high PARP1 expression and clinical outcomes in diverse types of cancers. The electronic databases for all articles about PARP1 expression and cancers were searched. Additionally, bioinformatics analysis was utilized to validate the results of the meta-analysis.

Magnetostructural transformation and magnetocaloric effect of Sn-bonded MnFeNiFeSiGe composite.

Magnetostructural coupling in MnMX (M = Co or Ni, X = Si or Ge) system attracts considerable attention for the accompanied multi-magnetoresponsive effects. However, due to the large stress generated from the structural transformation, the alloys become shattered or powder-like, hindering the further investigation and their applications. The possible solution is to embed the MnMX powders into metal matrix.

Electric field control of the magnetocaloric effect.

Through strain-mediated magnetoelectric coupling, it is demonstrated that the magnetocaloric effect of a ferromagnetic shape-memory alloy can be controlled by an electric field. Large hysteresis and the limited operating temperature region are effectively overcome by applying an electric field on a laminate comprising a piezoelectric and the alloy. Accordingly, a model for an active magnetic refrigerator with high efficiency is proposed in principle.

Long-term expression of glial cell line-derived neurotrophic factor slows, but does not stop retinal degeneration in a model of retinitis pigmentosa.

Retinitis pigmentosa is a group of diseases in which one of hundreds of mutations causes death of rod photoreceptor cells and then cones gradually die from oxidative damage. As different mutations cause rod cell death by different mechanisms, mutation-specific treatments are needed. Another approach is to use a neurotrophic factor to promote photoreceptor survival regardless of the mechanism of cell death, and previous studies have demonstrated encouraging short-term results with gene transfer of glial cell line-derived neurotrophic factor (GDNF).

Suppression of GLUT1; a new strategy to prevent diabetic complications.

High blood glucose results in high glucose levels in retina, because GLUT1, the sole glucose transporter between blood and retina, transports more glucose when blood glucose is high. This is the ultimate cause of diabetic retinopathy. Knockdown of GLUT1 by intraocular injections of a pool of siRNAs directed against SLC2A1 mRNA which codes for GLUT1 significantly reduced mean retinal glucose levels in diabetic mice.

Valproic acid regulates antioxidant enzymes and prevents ischemia/reperfusion injury in the rat retina.

Purposes: To investigate whether valproic acid (VPA) has a neuroprotective effect against ischemia/reperfusion (I/R) injury in the rat retina, and to elucidate the potential antioxidant mechanisms involved.

Methods: Adult male Wistar rats were randomly divided into four groups: sham (group A), sham plus VPA (group B), I/R plus vehicle (group C), and I/R plus VPA (group D). Retinal I/R injury was produced by inducing an exceedingly high intraocular pressure (IOP).

RPE cells were randomized into normal control group (no hydrogen peroxide), model group (hydrogen peroxide), model plus serum group (hydrogen peroxide and 10% control serum), model plus low-dose LQHBG group (hydrogen peroxide and low-dose LQHBG-medicated serum) and model plus high-dose LQHBG group (hydrogen peroxide and high-dose LQHBG-medicated serum).

Valproic acid-mediated neuroprotection in retinal ischemia injury via histone deacetylase inhibition and transcriptional activation.

Retinal ischemia plays a central role in several retinal diseases. The pathogenesis of retinal ischemia involves changes in gene expression. Valproic acid (VPA), a broad-spectrum histone deacetylase inhibitor, is an anticonvulsant and mood-stabilizing drug with neuroprotective effects.

Valproate protects the retina from endoplasmic reticulum stress-induced apoptosis after ischemia-reperfusion injury.

Valproate (VPA) is commonly used in the treatment of bipolar disorder and epilepsy. The mechanism underlying its clinical efficacy is complicated, including its ability to inhibit histone deacetylase (HDAC). Here, we show that VPA promoted endoplasmic reticulum (ER) chaperone expression and attenuated ER-induced apoptosis after ischemia/reperfusion (I/R) injury in retina.
