The aim of the present study was to investigate the prognostic significance of stromal interaction molecule 1 (STIM1) expression in gastric cancer (GC) and examine the association between STIM1 and epithelial‑mesenchymal transition (EMT). Immunohistochemical staining was performed to detect STIM1, E‑cadherin, β‑catenin and matrix metalloproteinase‑9 (MMP‑9) in 170 GC and 35 adjacent healthy gastric tissue samples. Positive staining of STIM1, E‑cadherin, β‑catenin and MMP‑9 in GC tissues was significantly greater compared with adjacent healthy tissues (P<0...

PURPOSE: Gastric cancer (GC) is still one of the most common malignancies with the majority of the tumors being diagnosed at advanced stage. The need for identification of prognostic and early detection biomarkers is thus compulsory. E-cadherin is one of the emerging biomarkers that is currently evaluated in the literature in the frame of epithelial-mesenchymal transition (EMT). Our aim was to study the expression of E-cadherin in the various histological subtypes of GC and to evaluate its prognostic value...

MicroRNAs have emerged as essential regulators of various cellular processes. We identified the role and underlying mechanisms of miR-2392 in gastric cancer (GC) metastasis. miR-2392 was down-regulated in GC cell lines and tissues, and overexpression of miR-2392 significantly inhibited GC invasion and metastasis in vitro and in vivo We identified MAML3 and WHSC1 as novel targets of miR-2392, and knockdown of MAML3 and WHSC1 had the same antimetastatic effect as that of miR-2392 in GC cells. These effects were clinically relevant, as low miR-2392 expression was correlated with high MAML3 and WHSC1 expression and poor survival in patients with GC...

Epithelial-mesenchymal transition (EMT) is an important biological process that is characteristic of malignant tumor cells with metastatic potential. We investigated the role of miR-551b in EMT and metastasis in gastric cancer (GC). We found that low miR-551b levels were associated with EMT, metastasis and a poor prognosis in GC patients. Further, two GC cell lines, MNK45 and SGC7901, exhibited lower miR-551b levels than the GES normal stomach cell line. Exposing MNK45 and SGC7901 cells to TGF-β1 resulted in cell morphology changes characteristic of EMT, which was confirmed by western blot analysis demonstrating low E-Cadherin and high N-Cadherin and Vimentin levels...

Diallyl trisulfide (DATS), a natural agent derived from garlic, has been tested for its antigastric cancer activities in various preliminary studies. However, more systematic pharmacodymatic (PD) and mechanistic evaluations are clearly needed. The aim of this study was to investigate the antitumor effects of DATS in the treatment of human gastric cancer cell SGC-7901 both in vitro and in vivo using widely recommended study procedures. DATS suppressed cancer cells proliferation and induced cell cycle arrest accompanied by an increase in the expressions of cyclin A2 and cyclin B1 in SGC-7901 cancer cells...

β-catenin has two different cellular functions: intercellular adhesion and transcriptional activity. The E3 ubiquitin ligase Siah1 causes ubiquitin-mediated degradation of the cytosolic β-catenin and therefore, impairs nuclear translocation and oncogenic function of β-catenin. However, the effect of Siah1 on the cell membrane bound β-catenin has not been studied. In this study, we identified that the carcinogenic bacterium H. pylori increased ETS2 transcription factor-mediated Siah1 protein expression in gastric cancer cells (GCCs) MKN45, AGS and Kato III...

Bradykinin (BK) has been reported to be involved in the progression of diverse types of cancer. In the present study, we investigated the possible role of BK in cell proliferation, migration, invasion and tumor growth of gastric cancer (GC). Cell proliferation was evaluated by MTT assays. Cell migration and invasion were assessed by Transwell assays. Tumor growth of nude mice was detected by establishing subcutaneous xenograft tumor model. Silencing of bradykinin B1 receptor (B1R) and the bradykinin B2 receptor (B2R) was performed by transfecting cells with si-B1R and si-B2R, respectively...

BACKGROUND: Patients with hereditary diffuse gastric cancer (HDGC), a cancer predisposition syndrome associated with germline mutations of the CDH1 (E-cadherin) gene, have few effective treatment options. Despite marked differences in natural history, histopathology, and genetic profile to patients afflicted by sporadic gastric cancer, patients with HDGC receive, in large, identical systemic regimens. The lack of a robust preclinical in vitro system suitable for effective drug screening has been one of the obstacles to date which has hampered therapeutic advances in this rare disease...

The mechanism underlying the metastasis of gastric cancer (GC) cells remains elusive. REG3A is considered an oncogene in various cancers, but in GC its role is unclear. Here, we report that the expression of REG3A was significantly increased in the tumor tissues of patients with GC compared with the matched normal tissues. Knockdown of REG3A induced by specific small interfering RNA (siRNA) significantly repressed the proliferation of GC cells for 24 h or 48 h. Moreover, knockdown of REG3A significantly suppressed the migration, invasion, and adhesion of GC cells in vitro...

Helicobacter pylori is a highly successful human bacterium, which is exceptionally equipped to persistently inhabit the human stomach. Colonization by this pathogen is associated with gastric disorders ranging from chronic gastritis and peptic ulcers to cancer. Highly virulent H. pylori strains express the well-established adhesins BabA/B, SabA, AlpA/B, OipA, and HopQ, and a type IV secretion system (T4SS) encoded by the cag pathogenicity island (PAI). The adhesins ascertain intimate bacterial contact to gastric epithelial cells, while the T4SS represents an extracellular pilus-like structure for the translocation of the effector protein CagA...

Gastric cancer (GC) is the most common epithelial malignancy worldwide. Basic transcription factor 3 (BTF3) plays a crucial role in the regulation of various biological processes. We designed experiments to investigate the molecular mechanism underlying the role of BTF3 in GC cell proliferation and metastasis. We confirmed that BTF3 expression was decreased in GC tissues and several GC cell lines. Lentivirus-mediated downregualtion of BTF3 reduced cell proliferation, induced S and G2/M cell cycle arrest, and increased apoptosis...

The ubiquitin-conjugating enzyme 2C (UBE2C) is the key component in the ubiquitin proteasome system (UPS) by partnering with the anaphase‑promoting complex (APC/C). A high UBE2C protein expression level has been reported in various types of human tumors. However, little is known about the precise mechanism by which UBE2C expression is downregulated in gastric cancer. We found in MGC‑803 and SGC‑7901 gastric cancer cells UBE2C‑deficient G2/M phase arrest in the cell cycle and subsequently decreased gastric adenocarcinoma tumorigenesis...

BACKGROUND: The E-cadherin, N-cadherin, and Snail genes are epithelial-mesenchymal transition (EMT)-inducible genes. Previous studies demonstrated that the expression of EMT markers in the primary tumor sites of gastric cancer correlates with tumor progression and prognosis. However, the clinical significance of the expression of these EMT markers in metastatic lymph nodes remains unclear. In the present study, we investigated the expression of these EMT markers in the primary tumor sites and metastatic lymph nodes...
