Alternative Splicing in Glioblastoma and its Clinical Implication in Outcome Prediction.

Background And Objective: Alternative splicing (AS) offers an important mechanism to form protein polymorphism. A growing body of evidence indicates the correlation between splicing abnormality and carcinoma. Nevertheless, an overall analysis of AS signatures in glioblastoma (GBM) is absent and urgently needed.

A Pan-Cancer Analysis of the Oncogenic Role of Methyltransferase-Like 1 in Human Tumors.

Background And Object: Although emerging cell- or animal-based evidence supports the relationship between methyltransferase-like 1 (METTL1) and cancers, no pan-cancer analysis is available.

Blood-Brain Barrier Dysfunction and the Potential Mechanisms in Chronic Cerebral Hypoperfusion Induced Cognitive Impairment.

Chronic cerebral hypoperfusion (CCH) is a major cause of vascular cognitive impairment and dementia (VCID). Although the underlying mechanisms have not been fully elucidated, the emerging data suggest that blood-brain barrier (BBB) dysfunction is one of the pivotal pathological changes in CCH. BBB dysfunction appears early in CCH, contributing to the deterioration of white matter and the development of cognitive impairment.

MRI-guided thrombolysis for lenticulostriate artery stroke within 12 h of symptom onset.

Stroke thrombolysis treatment is generally administered within 4.5 h, but a greater time window may be permitted depending upon the ischemic penumbra on neuroimaging.

Background: Dual antiplatelet therapy is considered beneficial in acute ischemic stroke (AIS) patients with intracranial artery stenosis (ICAS), with more bleeding events. Ginkgolide is shown to reduce platelet activation after infarction, which might be of benefit in AIS. We aimed to explore the effect of Ginkgolide in AIS patients with ICAS.

Isolation and neuronal apoptosis inhibitory property of bacoside-A3 via downregulation of β-amyloid induced inflammatory response.

Alzheimer's disease is one of the neurodegenerative disorders caused by neuronal degeneration and apoptosis in brain. Bacoside A and B isolated from the Bacopa monniera plant are responsible for cognitive effects. These compounds repair damaged neurons by promoting activity of kinases, synaptic activity restoration, and improvement of nerve transmission.

miR-433 Inhibits Neuronal Growth and Promotes Autophagy in Mouse Hippocampal HT-22 Cell Line.

MicroRNAs (miRNAs) have an increasing functional role in some neurodegenerative diseases. Autophagy, the degradation of bulk protein in the cytoplasm, is the quality control function of protein and has a protective role in the survival of neural cells. miR-433 may play a regulatory role in neurodegenerative diseases.

MicroRNA‑138 modulates glioma cell growth, apoptosis and invasion through the suppression of the AKT/mTOR signalling pathway by targeting CREB1.

Alterations in the expression of microRNA (miR)‑138 have been demonstrated to result in the development of several malignant tumours. However, the possible function of miR‑138 in human glioma cells remains unclear. The present study demonstrated that miR‑138 was significantly downregulated in 48 human glioma specimens by quantitative PCR analysis.

Quercetin, a natural antioxidant, has been recently shown to exert protective effects on endothelial function. However, the effects of quercetin on endothelial insulin resistance and its underlying mechanism are unclear.

Recombinant Tissue-Type Plasminogen Activator Study of Wake-Up Ischemic Strokes Guided by Rapid MRI.

Background: rt-PA intravenous thrombolytic therapy and its efficacy have been widely recognized and proved for strokes.
