Furthermore, IL‑33 inhibited the apoptosis of GC cells and regulated the expression of apoptosis‑associated proteins. In addition, IL‑33 stimulated the invasion and migration of GC cells. However, the transfection of ST2 small interfering (si)RNA attenuated the effects of IL‑33. Finally, IL‑33 stimulation increased the phosphorylation levels of ERK1/2, JNK and p38. buy GSK484 The transfection of ST2 siRNA could significantly inhibit the IL‑33‑induced ERK1/2, JNK and p38 activation. In conclusion, it was found that ST2 was highly expressed in GC tissues. IL‑33/ST2 promoted the malignant progression of GC cells by inducing the activation of ERK1/2, JNK and p38.It is well known that hydrostatic pressure (HP) is a physical parameter that is now regarded as an important variable for life. High hydrostatic pressure (HHP) technology has influenced biological systems for more than 100 years. Food and bioscience researchers have shown great interest in HHP technology over the past few decades. The development of knowledge related to this area can better facilitate the application of HHP in the life sciences. Furthermore, new applications for HHP may come from these current studies, particularly in tumor vaccines. Currently, cancer recurrence and metastasis continue to pose a serious threat to human health. The limited efficacy of conventional treatments has led to the need for breakthroughs in immunotherapy and other related areas. Research into tumor vaccines is providing new insights for cancer treatment. The purpose of this review is to present the main findings reported thus far in the relevant scientific literature, focusing on knowledge related to HHP technology and tumor vaccines, and to demonstrate the potential of applying HHP technology to tumor vaccine development.Advanced and recurrent ovarian cancer has a poor prognosis and is frequently resistant to numerous therapeutics; thus, safe and effective drugs are needed to combat this disease. Previous studies have demonstrated that triptolide (TPL) exhibits anticancer and sensitization effects against cisplatin (DDP)‑resistant ovarian cancer both in vitro and in vivo by inducing apoptosis; however, the involvement of autophagy induced by TPL in resistant ovarian carcinoma remains unclear. In the present study, the results revealed that TPL induced autophagy to facilitate SKOV3/DDP ovarian cancer cell death. The xenograft experiment revealed that the autophagy inhibitor CQ significantly reduced TPL‑mediated chemosensitization and tumor growth inhibition. Mechanically, TPL‑induced autophagy in SKOV3/DDP cells was associated with the induction of ROS generation and inhibition of the Janus kinase 2 (JAK2)/signal transducer and activator of transcription‑3 (STAT3) pathway. The inhibitory effect of TPL on the JAK2/STAT3 pathway could be restored in the presence of the antioxidant NAC. Furthermore, it was further determined that TPL disrupted the interaction between Mcl‑1 and Beclin1, which was prevented by the JAK2/STAT3 signaling activator IL‑6. Overall, the present results revealed a novel molecular mechanism whereby TPL induced lethal autophagy through the ROS‑JAK2/STAT3 signaling cascade in SKOV3/DDP cells. The present study has provided the groundwork for future application of TPL in the treatment of ovarian cancer.The present study investigated the role of electrical stimulation of the vagus nerve in the acute lung injury (ALI) inflammatory response induced by lipopolysaccharide (LPS) in rats. A rat model of ALI was established using LPS and by connecting an electrode to the left vagus nerve proximal to the heart in order to provide continuous electrical stimulation (1 mA; 1 msec; 10 Hz). After 120 min, the rat lung tissue was stained with hematoxylin and eosin and the expression of inflammatory factors was evaluated by reverse transcription‑quantitative PCR and western blot analysis. The change in apoptosis rate in cells from bronchoalveolar lavage fluid (BALF) was analyzed using flow cytometry. The results of the present study demonstrated that inflammatory cell infiltration, alveolar wall and interstitial thickening, and lung hyperemia in rats with LPS‑induced ALI were decreased following electrical stimulation of the vagus nerve. Electrical stimulation inhibited the expression levels of IL‑1, IL‑6, IL‑10, IL-8 and TNF‑α at both the mRNA and protein levels and decreased early and late apoptosis rates in inflammatory cells from BALF. The results indicated that vagus nerve stimulation can reverse the inflammatory response in lung injury, thereby exerting a pulmonary protective effect.Long non‑coding RNAs (lncRNAs) have been implicated in the development and progression of tumors. However, the roles and underlying mechanisms of long intergenic non‑protein coding RNA 1116 (LINC01116), a member of the lncRNA family, in glioma progression are largely unclear. The expression of LINC01116 and microRNA (miR)‑744‑5p in glioma tissues and cells was detected by reverse transcription‑quantitative PCR. The influences of LINC01116 or miR‑744‑5p on cell proliferation and invasion were evaluated by Cell Counting Kit‑8, colony formation and Transwell assays, and western blotting was used to detect the expression of p53 pathway proteins. A dual‑luciferase reporter system was used to locate common binding sites between miR‑744‑5p and LINC01116 or the 3' untranslated region of E3 ubiquitin‑protein ligase Mdm2 (MDM2). RNA immunoprecipitation was used to determine the interactions between RNAs and proteins. Moreover, a xenograft mouse model was constructed to investigate the effects of LINC01116 in vivo, followed by a TdT‑mediated dUTP nick end labeling assay to determine the degree of apoptosis in nude mouse tumors. LINC01116 was found to be highly expressed in glioma tissues, which was associated with a malignant phenotype. LINC01116 promoted the proliferation and invasiveness of glioma cells, and inhibited the p53 pathway by preserving the expression of MDM2 mRNA via miR‑744‑5p sponging. Furthermore, a low degree of miR‑744‑5p expression was observed in glioma tissues, which was negatively associated with the expression of LINC01116. Overexpression of miR‑744‑5p inhibited the proliferation and invasiveness of glioma cells, which was rescued by LINC01116. Finally, LINC01116 knockdown inhibited tumor growth in nude mice. In conclusion, LINC01116 is aberrantly expressed and promotes the progression of glioma by regulating the miR‑744‑5p‑MDM2‑p53 pathway. In future, targeting LINC01116 may therefore be a potential therapeutic approach for patients with glioma.
