Na-K-ATPase/GLT-1 interaction participates in EGCG protection against cerebral ischemia-reperfusion injury in rats.

Background: In China, stroke is the primary cause of adult death and disability. Because of the increased rate of blood vessel reperfusion, it is important to prevent cerebral ischemia-reperfusion injury, in which glutamate (Glu) excitotoxicity plays a critical role. The most important Glu transporter, GLT-1, is essential for the regulation of Glu, which is dependent on Na-K-ATPase (NKA)-induced ion concentration gradient differences.

Identification of Immune-Related Genes for Risk Stratification in Multiple Myeloma Based on Whole Bone Marrow Gene Expression Profiling.

Multiple myeloma (MM) is characterized by abnormal proliferation of bone marrow clonal plasma cells. Tumor immunotherapy, a new therapy that has emerged in recent years, offers hope to patients, and studying the expression characteristics of immune-related genes (IRGs) based on whole bone marrow gene expression profiling (GEP) in MM patients can help guide personalized immunotherapy. In this study, we explored the potential prognostic value of IRGs in MM by combining GEP and clinical data from the GEO database.

Na , K -ATPase participates in the protective mechanism of rat cerebral ischemia-reperfusion through the interaction with glutamate transporter-1.

Glutamate excitotoxicity in cerebral ischemia/reperfusion is an important cause of neurological damage. The aim of this study was to investigate the mechanism of Na+, K+-ATPase (NKA) involved in l ow concentration of ouabain (Oua, activating NKA)-induced protection of rat cerebral ischemia-reperfusion injury. The 2,3,5-triphenyltetrazolium chloride (TTC) staining and neurological deficit scores (NDS) were performed to evaluate rat cerebral injury degree respectively at 2 h, 6 h, 1 d and 3 d after reperfusion of middle cerebral artery occlusion (MCAO) 2 h in rats.
