Background: Fangjing decoction is a Traditional Chinese Medicine that exhibits anticonvulsive effects in treating febrile seizures (FS). Its action mechanism and the regulation on Akt/mammalian target of rapamycin (mTOR) pathway were revealed in the present study.Methods: FS model was established in Sprague–Dawley rats with or without Fangjing decoction treatment. On day 5, following initiation of drug treatment, seizures were monitored. Hippocampal neuron apoptosis was assessed using terminal dUTP nick end-labeling method. The levels of Bax, protein kinase B (Akt), phospho-Akt (p-Akt), mTOR, and p-mTOR proteins were analyzed using Western blotting. The content of hippocampal γ-aminobutyric acid (GABA) was measured by using ELISA assay.Results: Compared with the control group (n=8), Fangjing decoction effectively shortened escape latency and duration of FS and decreased the frequency of FS in rats (n=8). Concomitantly, the apoptosis of hippocampal neurons, as well as Bax protein levels were also decreased in FS rats which were treated with Fangjing decoction. In addition, the Akt/mTOR signaling was found to be activated in rat hippocampus following FS, as evidenced by increased p-Akt and p-mTOR, while Fangjing decoction could inhibit the activation of Akt/mTOR signaling. Furthermore, the low GABA content in rat hippocampus following FS was significantly elevated by Fangjing decoction treatment. More importantly, SC79, a specific activator for Akt, apparently attenuated the protective effects of Fangjing decoction on FS rats.Conclusion: These results suggest that Fangjing decoction protects the hippocampal neurons from apoptosis by inactivating Akt/mTOR pathway, which may contribute to mitigating FS-induced brain injury.
The association between ATP-binding cassette subfamily B member 1 (ABCB1) C3435T and C1236T polymorphisms and the risk for childhood acute lymphoblastic leukemia (ALL) is inconclusive. We conducted a meta-analysis of all published studies to determine the association of ABCB1 C3435T and C1236T polymorphisms and pediatric ALL risk. A systematic retrieval of relevant publications from the PubMed and Web of Science databases was performed. Data were calculated and statistical analysis was performed using STATA version 12.0 software. Metaanalysis results showed no significant association between C3435T polymorphism and pediatric ALL risk (TT vs. CC: odds ratio [OR] = 1.20, 95% confidence interval [CI] = 0.95-1.52; CT vs. CC: OR = 1.00, 95% CI = 0.82-1.23; the dominant model: OR = 1.07, 95% CI = 0.89-1.29; the recessive model: OR = 1.17, 95% CI = 0.84-1.62). Similarly, there was no association found for the C1236T polymorphism (TT vs. CC: OR = 1.18, 95% CI= 0.82-1.70; CT vs. CC: OR = 1.08, 95% CI = 0.80-1.45; the dominant model: OR = 1.10, 95% CI= 0.83-1.46; the recessive model: OR = 0.98, 95% CI = 0.61-1.58). Similar results were observed in the subgroup analyses on ethnicity and Hardy-Weinberg equilibrium. The present meta-analysis found no evidence for ABCB1 C3435T and C1236T polymorphisms as risk factors for pediatric ALL.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
