BACKGROUND: Microglia is responsible for neuroinflammation, which may aggravate brain injury in diseases like epilepsy. Mammalian target of rapamycin (mTOR) kinase is related to microglial activation with subsequent neuroinflammation. In the present study, rapamycin and everolimus, both as mTOR inhibitors, were investigated in models of kainic acid (KA)-induced seizure and lipopolysaccharide (LPS)-induced neuroinflammation. METHODS: In vitro, we treated BV2 cells with KA and LPS...

Glioma is one of the most common tumors in central nervous system. The median life expectancy for glioma patients is only 13-15 months. NIMA-related expressed kinase 2 (NEK2) is a kind of serine-threonine kinases and involves in carcinogenesis and progression of cancer, however, the specific roles in the glioma remains unknown. We found the high expression of NEK2 was positively correlated with deteriorated severity of glioma. Therefore, we sought to investigate the effects of NEK2 on U87 and U251 cells. To explore the expression of NEK2 and alteration of signaling pathway factors, qRT-PCR and Western blot analysis were performed...
