Zhao Liu, Yan Yan, Sizhe Cao, Yi Chen
This study aimed to elucidate the roles of long non-coding RNA SNHG14 in gastric cancer development. LncRNA SNHG14 was markedly up-regulated in gastric cancer tissues and cells. Knockdown of SNHG14 significantly inhibited SGC-7901 cell viability, migration, invasion, and promoted cell apoptosis. In addition, miR-145 was negatively regulated by SNHG14 and the effects of SNHG14 knockdown on cell viability, apoptosis, migration, invasion, and the expression of apoptosis-related proteins and EMT-markers were reversed by inhibition of miR-145 at the same time...

Kita-Kyushu lung cancer antigen-1 (KK-LC-1) is a cancer/testis antigen (CTA) and predominant target for cancer immunotherapy. Our previous study indicated that KK-LC-1 was expressed in 82% of gastric cancers, and also in 79% of early stage of gastric cancers, with a correlation to Helicobacter pylori (H. pylori) infection. In addition, we found that KK-LC-1 was occasionally expressed at non-tumour sites of stomachs carrying tumours. Here, we investigated the characteristics of KK-LC-1 expression at non-tumour sites and the clinical utility of these phenomena...

NK cells are important in innate immunity for their capacity to kill infected or cancer cells. The killer cell immunoglobulin-like receptors (KIR) are a family of polymorphic genes with inhibitory and activating functions. The main driving force for gastric cancer (GC) development is a chronic response, which causes an increase of NK cells in the gastric mucosa. The aim of this work was to study polymorphisms in KIR genes in patients with either GC or non-atrophic gastritis (NAG). We studied 242 patients (130 with NAG and 112 with GC) and contrasted with 146 asymptomatic individuals...

A major challenge in cancer genomics is identifying "driver" mutations from the many neutral "passenger" mutations within a given tumor. To identify driver mutations that would otherwise be lost within mutational noise, we filtered genomic data by motifs that are critical for kinase activity. In the first step of our screen, we used data from the Cancer Cell Line Encyclopedia and The Cancer Genome Atlas to identify kinases with truncation mutations occurring within or before the kinase domain...

INTRODUCTION: Helicobacter pylori express a large array of antigens, each of which is duly responsible for successful colonization and pathogenesis. Here, we have studied host serum antibody responses to four of its immunodominant antigens in association with the infection status and the resulting clinical outcomes. METHODS: For this purpose, four individual H. pylori proteins (UreB, CagA, Tip-α and HP0175) were produced in recombinant forms. Serum antibody responses of 246 (75 GC and 171 NUD) patients, against the above antigens, were evaluated by multiplex immunoblotting...

As a member of the BamHI-A rightward transcripts family of the Epstein-Barr virus (EBV), RPMS1 expression has been confirmed in all EBV-associated tumors. However, few studies have investigated the single-nucleotide polymorphisms (SNPs) of RPMS1, and only one SNP site (g155391a) has been reported to be associated with nasopharyngeal carcinoma occurrence. The objective of this study was to investigate the polymorphism of RPMS1 in EBV-associated tumors (gastric carcinoma, nasopharyngeal carcinoma, and lymphoma)...

Transmembrane-4-L-six-family member-1 (TM4SF1), a tumor-associated antigen, is overexpressed in most epithelial cell carcinomas and a potential target for antibody-mediated therapy. However, the role of TM4SF1 in gastric cancer has not been elucidated. The aim of this study was to investigate the clinical significance of TM4SF1 expression in gastric carcinoma (GC) tissues using 152 GC tissue samples and matched adjacent nontumor tissue samples analyzed by immunohistochemistry, and 13 fresh GC tissue samples analyzed by Western blotting...

Although extensive efforts have been made in recent decades to treat advanced gastric cancer with comprehensive therapy based on chemotherapy, effective anti-gastric cancer therapeutics are still lacking in the clinics. Therefore, potent novel anti-gastric cancer ways are greatly needed. Here, we explored hyperbaric oxygen treatment as a novel and effective adjuvant treatment method which has anti-gastric cancer effects when used together with melatonin. When performed together with MLT, HBO effectively inhibited tumorigenicity of gastric cancer through selectively inducing a robust tumor suppressive apoptosis response...

Metformin is widely used for the management of type 2 diabetes mellitus (T2DM). Recently growing evidence has shown its anti-cancer effects. The results are mainly obtained from observational studies and thus, little information is available concerning the mechanisms of action. Adenosine monophosphate (AMP)-activated protein kinase (AMPK) plays an important role in the mechanism of action of metformin. The anti-cancer mechanisms of metformin include direct and indirect effects. The direct effects of metformin include AMPK-independent and AMPK-dependent effects, whereas the decrease in glucose level, hyperinsulinemia, and Insulin-like growth factor 1 (IGF-1) level was considered its indirect effects...

Protein ubiquitination is involved in many cellular processes, such as protein degradation, DNA repair, and signal transduction pathways. Ubiquitin-conjugating (E2) enzymes of the ubiquitination pathway are associated with various cancers, such as leukemia, lung cancer, and gastric cancer. However, to date, detection of E2 activities is not practicable for capturing the pathological conditions of cancers due to complications related to the enzymatic cascade reaction. To overcome this hurdle, we have recently investigated a novel strategy for measuring E2 activities...

The pressing need for improved therapeutic outcomes provides a good rationale for identifying effective strategies for alimentary tract (AT) cancer treatment. The potential re-sensitivity property to chemo- and immunotherapy of low-dose decitabine has been evident both preclinically and in previous phase I trials. We conducted a phase Ib/II trial evaluating low-dose decitabine primed chemo-immunotherapy in patients with drug-resistant relapsed/refractory esophageal, gastric or colorectal cancers. Forty-five patients received either the 5-day decitabine treatment with subsequent re-administration of the previously resistant chemotherapy (decitabine primed chemotherapy, D-C cohort) or the aforementioned regimen followed by cytokine-induced killer cells therapy (decitabine primed chemotherapy and CIK treatment, D-C+CIK cohort) based on their treatment history...
