BARX2 expression was negatively correlated with DNMT (a marker for DNA methylation) expression in the gastric tissues. The BARX2 promoter fragment was hypermethylated in the GC cell lines. Overexpression of BARX2 significantly inhibited GC cell proliferation, clonal formation, and migration. Stable BARX2 transfection inhibited tumor formation in xenograft mice, which was correlated with decreased expression of E‑cadherin, proliferation markers, and matrix metalloproteinases. In conclusion, BARX2 expression is aberrantly reduced in GC, which is associated with increased DNA methylation of its promoter. BARX2 inhibits GC cell proliferation, migration, and tumor formation, suggesting that BARX2 acts as a tumor suppressor in gastric carcinogenesis.Hispidulin is a medicinal natural compound isolated from S. involucrata, which exhibits potent anticancer properties. However, there are few reports on its effects on lung cancer cells. Therefore, the current study investigated the effects of hispidulin on cell viability and apoptosis in human non‑small‑cell lung cancer (NSCLC) cell lines NCI‑H460 and A549 in vitro and in vivo. Methyl thiazolyl tetrazolium, colony formation assay, Hoechst 33342 staining, flow cytometry and western blotting were performed on Human NCI‑H460 and A549 cells. A mouse xenograft model was also established using NCI‑H460 cells. The results showed that the growth of NCI‑H460 and A549 cells was inhibited, while apoptosis was promoted by hispidulin via increased generation of reactive oxygen species (ROS) in a dose‑dependent manner. Furthermore, hispidulin triggered apoptosis in NSCLC cells through upregulating the expression of cleaved caspase‑3 and cleaved poly [ADP‑ribose] polymerase. All these effects were reversed upon pretreatment with glutathione, a selective ROS inhibitor. In addition, endoplasmic reticulum stress (ER stress) in NCI‑H460 cells was activated by hispidulin. Pretreatment with tauroursodeoxycholic acid, a specific ER stress inhibitor, effectively reduced the cell apoptosis induced by hispidulin. In conclusion, hispidulin induces ROS‑mediated apoptosis via activating the ER stress pathway. The current study provides theoretical basis for the antitumor effect of hispidulin in NSCLC.Ketamine is a widely used general anesthetic and has been reported to demonstrate neurotoxicity and neuroprotection. Investigation into the regulatory mechanism of ketamine on influencing neural development is of importance for a better and safer way of relieving pain. Reverse transcription‑quantitative polymerase chain reaction and western blotting were used to detect the critical neural associated gene expression, and flow cytometry to detect the neural differentiation effect. Hence, in the present study the underlying mechanism of ketamine (50 nM) on neural differentiation of the mouse embryonic stem cell (mESC) line 46C was investigated. The results demonstrated that a low dose of ketamine (50 nM) promoted the differentiation of mESCs to neural stem cells (NSCs) and activated mammalian target of rapamycin (mTOR) by upregulating the expression levels of phosphorylated (p)‑mTOR. Furthermore, inhibition of the mTOR signaling pathway by rapamycin or knockdown of mTOR suppressed neural differentiation. A rescue experiment further confirmed that downregulation of mTOR inhibited the promotion of neural differentiation induced by ketamine. Taken together, the present study indicated that a low level of ketamine upregulated p‑mTOR expression levels, promoting neural differentiation.Following the publication of this article, the authors have realized that an error was made with the description of the first and fourth listed affiliation addresses "North China University of Science and of Technology", should have been written as "North China University of Science and Technology".

Suberoylanilide hydroxamic acid (SAHA), a pan‑histone deacetylase inhibitor, has anti‑inflammatory effects and induces autophagy. To investigate whether SAHA ameliorates IRI and the mechanisms by which SAHA exerts its effects, an orthotopic liver transplantation (OLT) rat model was established after treatment with SAHA. The results showed that SAHA effectively ameliorated OLT‑induced IRI by reducing M1 polarization of KCs through inhibition of the AKT/glycogen synthase kinase (GSK)3β/NF‑κB signaling pathway. Furthermore, the present study found that SAHA upregulates autophagy 5 protein (ATG5)/LC3B in KCs through the AKT/mTOR signaling pathway and inhibition of autophagy by knockdown of ATG5 in KCs partly impaired the protective effect of SAHA on IR‑injured liver. Therefore, the current study demonstrated that SAHA reduces M1 polarization of KCs by inhibiting the AKT/GSK3β/NF‑κB pathway and upregulates autophagy in KCs through the AKT/mTOR signaling pathway, which both alleviate OLT‑induced IRI. The present study revealed that SAHA may be a novel treatment for the amelioration of OLT‑induced IRI.
