Perampanel is a highly selective and non-competitive α-amino-3-hydroxy-5 -methyl-4-isoxazole propionate (AMPA) receptor (AMPAR) antagonist, which has been licensed as an orally administered antiepileptic drug in more than 55 countries. Recently, perampanel was found to exert neuroprotective effects in hemorrhagic and ischemic stroke models. In this study, the protective effect of perampanel was investigated. The protective effect of perampanel was investigated in an in vitro traumatic neuronal injury (TNI) model in primary cultured cortical neurons. We found that perampanel significantly preserved morphological changes, attenuated lactate dehydrogenase (LDH) release and inhibited caspase-3 activation after TNI. The TNI-induced necroptosis, as evidenced by flow cytometry, was markedly reduced by perampanel treatment. The results of western blot showed that perampanel decreased the expression and phosphorylation of the necroptotic factors, receptor protein interacting kinase 1 (RIPK1) and RIPK3. In addition, treatment with perampanel increased the phosphorylation of Akt and GSK3β in a time-dependent manner up to 24 h after TNI. Treatment with the Akt inhibitor LY294002 partially reversed the protective effects of perampanel. Our present data suggest that necroptosis plays a key role in the pathogenesis of neuronal death after TNI, and that perampanel might have therapeutic potential for patients with traumatic brain injury (TBI).

G protein-coupled receptor 4 (GPR4) has been reported to play an essential role in regulating the proliferation, migration and angiogenesis of vascular endothelial cells. GPR4 is also suggested play roles in the growth and angiogenesis of ovarian cancer. To explore the function of GPR4 and transcription factor 7 (TCF7) in ovarian cancer. The expression levels of genes involved in Wnt signaling were validated by quantitative real-time-PCR (q-RT-PCR). The effects of GPR4 and TCF7 on ovarian cancer cell invasion and apoptosis were determined using soft agar, Transwell assay and flow cytometric assay. Protein levels of beta-catenin, MMP-2 and MMP-9 were evaluated by Western blotting. In this study, we found that GPR4 and TCF7 had the capacity to control cell division by altering cell cycle distribution, anchorage-independent growth, and directional cell motility of ovarian cancer cell, A2780. Also, we showed that knockdown of GPR4 and TCF7 in ovarian cancer cells A2780 induced significantly decreased cell growth and decreased invasion, as well as increased apoptosis. Down-regulation of TCF7 resulted in the decreased MMP-2 and MMP-9 level. The results implicate that GPR4 behaves like an oncogene and may function through WNT pathway molecule, TCF7. Downregulation of GPR4 and TCF7 essentially inhibited cell growth and invasion and enhanced apoptosis of ovarian cancer cells, which may lay the foundation of ovarian cancer treatment.

Radiation therapy is stressful for patient and family. After a child's cancer diagnosis, parents face the burden of dealing with fear, their children's needs and the unfamiliarity of radiotherapy procedure. The objective of this paper is to present methods in order to alleviate the total psychological stress those children and parents feel during radiation course. A literature search was performed until January 2020.
