Background. Paeoniflorin has been reported to exert antitumor effects on human cancers. However, the role of paeoniflorin in gastric cancer and the underlying molecular mechanism are unelucidated. Therefore, we determined whether paeoniflorin could exhibit anticancer activity in gastric cancer cells. Methods. MTT was used to measure the viability of cells after paeoniflorin treatment. FACS was performed to examine cell apoptosis. Wound healing and transwell invasion assays were conducted to examine cell migratory and invasive activities. Western blotting was used to explore the mechanism by which paeoniflorin exerted tumor suppressive effects. Results. We found that paeoniflorin suppressed cell growth, enhanced apoptosis, and reduced cell invasion. Notably, we showed that paeoniflorin inhibited the expression of TAZ in gastric cancer cells. The overexpression of TAZ abrogated the antitumor activity of paeoniflorin in gastric cancer cells. In contrast, the downregulation of TAZ promoted the tumor suppressive effects of paeoniflorin treatment. Conclusion. Hence, targeting TAZ with paeoniflorin could be a novel approach for the treatment of human gastric cancer.

Abstract AimGastric cancer is one of the most common malignant tumors.Chrysophanol has been reported to have antitumor effects on a variety of cancers, but the role of chrysophanol in gastric cancer remains unclear. The aim of this study was to investigate the effects of chrysophanol on proliferation, pyroptosis, migration and invasion of gastric cancer cells.MethodsMKN 28 and AGS cells were treatde with different concentrations of chrysophanol, then cell proliferation, migration,invasion and pyroptosis were decteed by CCK-8, Colony-forming assay, Wound Healing assay, Transwell and flow cytometry, respectively.Subsequently, NLRP3 siRNA was transfected into MKN 28 cells, cell proliferation pyroptosis, migration and invasion were reassessed in these transfected cells. The expression of caspase-1 and IL-1β in the downstream of NLRP3 was detected by qRT PCR and Western blot.ResultsChrysophanol significantly inhibited the proliferation of GC cells, promoted pyroptosis, inhibited cell migration and invasion, and up-regulated the expression level of NLRP3 inflammasome in GC cells. Silencing NLRP3 inhibited the effects of chrysophanol on proliferation, pyroptosis, migration and invasion of MKN 28 cells. Chrysophanol plays an anti-cancer role through high expression of NLRP3.CoclusionsChrysophanol can inhibit the proliferation, migration and invasion of gastric cancer cells by regulating NLRP3, promote the death of gastric cancer cells, and play an anti-tumor role,which is a clinical strategy with great potential for the treatment of gastric cancer.

Abstract PAX8 is identified as a regulator in the pathogenesis of human tumors and an indicator of the prognosis for patients. However, the role of PAX8 on proliferation in gastric cancer have not been studied. This study was aimed to explore the expression pattern of PAX8 in gastric cancer, and investigate the effect of PAX8 on the proliferation of gastric cancer cells. PAX8 and SOX13 were identified to be synchronously upregulated in primary gastric cancer in human gastric cancer tissues and the gastric cancer datasets of TCGA, and gastric cancer patients of combined high PAX8 and SOX13 expression showed poor prognosis. Furthermore, SOX13 can mediate PAX8 and its targeted genes, Aurora B and Cyclin B1, expression in AGS and MGC803 cell lines. Flow cytometry and EdU incorporation assays showed that silencing PAX8 can block the cell cycle of gastric cancer cell in G1 phase and SOX13 expression can rescue the arrested proliferative process induced by PAX8 silenced in CCK8 and colony formation assays. Thus, combined SOX13 and PAX8 expression regulate the proliferation of gastric cancer cells, and both SOX13 and PAX8 play an oncogene function in gastric cancer.

Abstract Background Gastric cancer is a highly aggressive malignant tumor with heterogeneity and is still a global health problem. The present study aimed to investigate the role of Cyclin I-like (CCNI2) in the regulation of phenotype and tumorigenesis, as well as its underlying mechanisms. Method The expression profile of CCNI2 in gastric cancer was determined based on The Cancer Genome Atlas (TCGA) database and immunohistochemical staining. The effects of altered CCNI2 expression on the biological phenotypes such as proliferation, clone formation, apoptosis and migration of gastric cancer cell lines BGC-823 and SGC-7901 were investigated. Mice xenograft models were established to reveal the role of CCNI2 knockdown on tumorigenesis. The potential mechanism of CCNI2 regulating gastric cancer was preliminarily determined by RNA sequencing. Result CCNI2 was abundantly expressed in gastric cancer and was positively correlated with pathological stage. Knockdown of CCNI2 slowed down the malignant progression of gastric cancer by inhibiting tumor cell proliferation, increasing the susceptibility to apoptosis and suppressing migration. Moreover, downregulation of CCNI2 attenuated the ability of gastric cancer cells to form tumors in mice. Additionally, there was an interaction between CCNI2 and transcription factor hepatoma-derived growth factor (HDGF) in SGC-7901 cells. Knockdown of CCNI2 alleviated the promoting effects of HDGF overexpression in gastric cancer cells. Conclusions CCNI2 promoted the progression of human gastric cancer through HDGF, which drew further interest regarding its clinical application as a potential therapeutic target.
