It has previously been demonstrated that miRNA (miR)‑647 exhibits an important role in various cancers, and is aberrantly expressed in gastric cancer (GC). However, the exact role of miR‑647 in GC still remains unclear. The present study aimed to investigate the functional significance of miR‑647 and its target gene in GC. TargetScan and Miranda databases were used to predict the putative targets, and the prediction was validated by Dual‑luciferase Reporter Assays. To investigate whether miR‑647 affects GC cell behavior, a stable miR‑647‑overexpression/low‑expression cell line was generated by transfection with miR‑647 mimic/inhibitor...

Pectolinarigenin (PEC), a natural flavonoid present in Cirsium chanroenicum and in some species of Citrus fruits, has various pharmacological benefits such as anti-inflammatory and anti-cancer activities. In the present study, we investigated the anti-cancer mechanism of PEC induced cell death caused by autophagy and apoptosis in AGS and MKN28 human gastric cancer cells. The PEC treatment significantly inhibited the AGS and MKN28 cell growth in a dose-dependent manner. Further, PEC significantly elevated sub-G1 phase in AGS cells and G2/M phase cell cycle arrest in both AGS and MKN28 cells...

The combination approach is now a well-established treatment for cancer. The present study evaluated the potential of curcumin and resveratrol on p53 post-translational modifications during gastric cancer. We segregated rats into five groups that included normal controls, dimethylhydrazine (DMH) treated, DMH + curcumin treated, DMH + resveratrol treated, and DMH + curcumin + resveratrol treated. Morphological analyses of tumor nodules confirmed carcinogenesis in rats after 25 weeks of DMH administration. The DMH treatment significantly induced carcinogenesis, as evidenced by high tumor burden in DMH-treated rats compared with controls...

Gastric cancer is a common cancer of the gastrointestinal tract and the second most prevalent cause of cancer-associated mortality globally. Gastric cancer-associated mortality is increased in China compared with that in other countries. Key contributors to the poor prognosis of gastric cancer include late clinical presentation and genetic heterogeneity. Treatment based on the subtype of gastric cancer is important for effective therapy. The overexpression of the erb-b2 receptor tyrosine kinase 2 (ERBB2) gene and protein is associated with gastric cancer in humans...

The optimal management of patients with resection line involvement after endoscopic or surgical treatment for gastric cancer is debated. In contrast to previous reports, we examined both the experience of endoscopists and surgeons in early-stage lesions and the wide variation in treatments proposed for advanced disease in case of infiltration of resection margins. A PubMed search for papers using the key words: gastric or stomach cancer, or Carcinoma; gastrectomy and positive margins; surgical margins or resection line or endoscopic margin involvement; and R1 resection, from January 2000 to July 2015 was undertaken...

BACKGROUND: For cancers of the distal gastroesophageal junction or the proximal stomach, proximal gastrectomy can be performed. It is associated with several perioperative benefits compared with total gastrectomy. The use of laparoscopic proximal gastrectomy (LPG) has become an increasingly popular approach for select tumors. METHODS: We describe our method of LPG, including the preoperative work-up, illustrated depictions of the key steps of the surgery, and our postoperative pathway...

Obtaining detailed individual-level data on both exposure and cancer outcomes is challenging, and it is difficult to understand and characterize how temporal aspects of exposures translate into cancer risk. We show that, in lieu of individual-level information, population-level data on cancer incidence and etiologic agent prevalence can be leveraged to investigate cancer mechanisms and to better characterize and predict cancer trends. We use mechanistic carcinogenesis models [multistage clonal expansion (MSCE) models] and data on smoking, Helicobacter pylori ( H...

Human Ataxin-3 protein was first identified as a transcript from patients with Machado-Joseph disease (MJD), also known as spinocerebellar ataxia type 3 (SCA3). Recent studies have demonstrated that Ataxin-3 is involved in gastric cancer and lung cancer. However, the role of Ataxin-3 in testicular cancer (TC) remains poorly understood. This study aims to explore the significance of Ataxin-3 expression in TC. Firstly, we investigated 53 paired TC and para-tumor tissues and found that Ataxin-3 was overexpressed in TC tissues, and this overexpression of Ataxin-3 was correlated with tumor stages...

Current studies aiming at identifying single immune markers with prognostic value have limitations in the context of complex antitumor immunity and cancer immune evasion. Here, we show how the integration of several immune markers influences the predictions of prognosis of gastric cancer (GC) patients. We analyzed Tissue Microarray (TMA) by multiplex immunohistochemistry and measured the expression of immune checkpoint molecule PD-L1 together with antitumor CD8 T cells and immune suppressive FOXP3 Treg cells in a cohort of GC patients...

The well-studied catalytic role of urease, the Ni-dependent conversion of urea into carbon dioxide and ammonia, has been shown to protect Helicobacter pylori against the low pH environment of the stomach lumen. We hypothesized that the abundantly expressed urease protein can play another, non-catalytic role in combating oxidative stress via Met-residue mediated quenching of harmful oxidants. Three catalytically inactive urease mutant strains were constructed by single substitutions of Ni binding residues. The mutant versions synthesize normal levels of urease and the altered versions retain all methionine residues...

Identification of early-stage tumor and monitoring therapeutic efficacy and recurrence or metastasis of colorectal cancer (CRC) are urgently warranted for improving the outcome of CRC patients and reducing the disease-related mortality. In this study, we evaluated the diagnostic value of cell-free circulating methylated SEPT9 (mSEPT9) for CRC and beyond CRC and examined the potentiality of mSEPT9 in assessing therapeutic efficacy and monitoring recurrence of CRC. Our results confirmed the favorable diagnostic value of plasma mSEPT9 for CRC, with a sensitivity of 61...

To be able to survive, Helicobacter pylori must adhere to the gastric epithelial cells of its human host. For this purpose, the bacterium employs an array of adhesins, for example, AlpA. The adhesin AlpA has been proposed as a major adhesin because of its critical role in human stomach colonization. Therefore, understanding how AlpA evolved could be important for the development of new diagnostic strategies. However, the genetic variation and microevolutionary patterns of alpA have not been described in Colombia...
