OBJECTIVE: Gastric carcinoma (GC) is one of the most common malignant tumors around the world. It is featured as high morbidity, poor prognosis, and short survival, thus seriously threats to the quality of life. The mechanism of GC is still unclear, leading to a difficulty in the treatment. CD44V6 plays an important role in tumorigenesis and progression, while its role in GC still needs further elucidation. PATIENTS AND METHODS: GC tissue and para-carcinoma tissue were collected from patients in different tumor-mode-metastasis (TNM) stages...

OBJECTIVE: In recent years, microRNAs have been identified to participate in tumor genesis and progression of different tumors including gastric cancer. However, the role of miR-377 played in gastric cancer (GC), and its mechanisms have not been demonstrated. PATIENTS AND METHODS: We detected miR-377 expression level in 86 GC and adjacent normal tissue samples by quantitative reverse transcription PCR (qRT-PCR) as well as in GC cell lines. The relationship between miR-377 and clinical pathological features was analyzed...

Background and study aims Localized approaches are being increasingly used in the management of early gastric adenocarcinoma; however, there are limited data on lymph node metastasis in the US population. This study examined the incidence and predictors of lymph node involvement for early-stage gastric adenocarcinomas in the USA. Patients and methods Data were abstracted from the national SEER database from 2004 to 2013. Exclusion criteria included: cases with unknown tumor characteristics, unknown patient characteristics, metastatic disease, neoadjuvant radiation, and lack of surgical resection or lymph node evaluation...

Zuotin-related factor 1 (ZRF1) is a recently characterized epigenetic factor involved in transcriptional regulation and is highly overexpressed in several malignancies, but it is not known whether it plays a role in gastric cancer (GC). In this study, we investigated whether ZRF1 acts as a cancer-promoting gene through its activation/overexpression in GC. We analyzed five GC cell lines and 133 primary tumors, which had been curatively resected in our hospital between 2001 and 2003. Overexpression of ZRF1 was detected in GC cell lines (four out of five lines, 80...

BACKGROUND: The aim of this study was to investigate the survival of patients with signet ring cell carcinoma (SRCC) based on primary tumor location. METHODS: Patient data were obtained from the Surveillance, Epidemiology, and End Results database (1988-2012) with ≥200 cases per tumor location. Cox regression analysis was used to investigate prognostic factors of cause-specific survival (CSS). RESULTS: We identified 24,171 patients. Of the patients, 63...

This study aims to explore effects of neutrophil gelatinase-associated lipocalin (NGAL) gene silencing on the proliferation and apoptosis of human gastric cancer MGC-803 and SGC-7901 cells. NGAL-siRNA was designed, synthesized and randomly divided into NGAL-siRNA and control-siRNA groups. Gastric cancer cells MGC-803 and SGC-7901 were grouped into blank, NGAL-OE, and control-OE groups. Expression of NGAL and apoptosis-related proteins were detected by qRT-PCR and Western blotting. Cell cycle and apoptosis were tested by flow cytometry, and cell proliferation by water soluble tetrazolium-1 (WST-1) assay...

Gastric cancer ranks as the second leading cause of malignancy-related death worldwide, and always diagnosed at advanced stage. MicroRNA-222-3p (miR-222-3p) is aberrantly upregulated in various malignant tumors including gastric cancer, but its role and underlying molecular mechanisms in gastric cancer remain largely unknown. Helicobacter pylori (H. pylori) infection acts as a trigger in the development of gastric cancer, and increasing evidence suggests that H. pylori affects microRNA expression. In this study, gastric cancer tissue samples were divided into H...

AIM: To evaluate the prognostic role of interim analysis of 18F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT) volumetric parameters in patients with recurrent or metastatic advanced gastric cancer (AGC) treated with fluoropyrimidine-based palliative chemotherapy. METHODS: Forty-four patients who underwent baseline and interim PET/CT scanning during palliative chemotherapy were analyzed retrospectively. Initial and change of metabolic parameters (MP) - metabolic tumor volume (MTV), tumor lesion glycolysis (TLG) and maximum and mean standardized uptake values (SUV) were measured with PET/CT...

BACKGROUND/AIMS: Human leukocyte antigen-G (HLA-G) plays an important role in inhibiting natural killer (NK) cell function and promoting immune escape. However, the specific mechanism of HLA-G on NK in gastric cancer (GC) remains not well understood. This study investigated the expression of HLA-G in GC and the role of HLA-G-effected NK cells in GC progression. METHODS: HLA-G expression in GC tissues obtained from 49 patients with GC was analyzed by immunohistochemistry and western blot...

AIMS: Evidence shows that aberrant expression of long non-coding RNA (lncRNA) is closely associated with tumor development and progression. However, the role of lncRNA in environmental carcinogen induced gastric tumorigenesis remains largely unknown. This study aimed at investigating the function role of lncRNA in N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) induce malignantly transformed human gastric epithelial cells. MAIN METHODS: In this study, high-throughput sequencing and qRT-PCR assay revealed marked downregulation of lncRNA LOC101927497 in the malignant transformed gastric epithelial cells induced by MNNG (GES-1-T cells), gain-of-function and loss-of-function assays showed that LOC101927497 can suppress the proliferation and migration of GES-1-T cells in vitro...

BACKGROUND: In recent reports, re-irradiation with stereotactic body radiotherapy for lung tumors in patients previously treated with thoracic radiation therapy resulted in several serious toxicities. Serious non-lung toxicities were observed mostly in patients with central tumors, but we experienced a case of fatal gastric perforation after a second stereotactic body radiotherapy in a patient with a peripheral lung tumor. CASE PRESENTATION: An 83-year-old Asian man was diagnosed with T2N0M0 lung cancer in the form of squamous cell carcinoma in the lower lobe of his left lung...

We generated a novel mouse strain expressing transgenic human interleukin-15 (IL-15) using the severe immunodeficient NOD/Shi-scid-IL-2Rγ null (NOG) mouse genetic background (NOG-IL-15 Tg). Human natural killer (NK) cells, purified from the peripheral blood (hu-PB-NK) of normal healthy donors, proliferated when transferred into NOG-IL-15 Tg mice. In addition, the cell number increased, and the hu-PB-NK cells persisted for 3 months without signs of xenogeneic graft versus host diseases (xGVHD). These in vivo-expanded hu-PB-NK cells maintained the original expression patterns of various surface antigens, including NK receptors and killer cell immunoglobulin-like receptor (KIR) molecules...

MicroRNAs (miRs) have been demonstrated to play promoting or tumor suppressive roles in various human cancers, but the regulatory mechanism of miR-29b underlying gastric cancer development and progression still remains largely unclear. In the present study, we found that miR-29b was significantly downregulated in gastric cancer tissues and cell lines. Low expression of miR-29b was significantly associated with DNA methylation, and treatment with DNA methyltransferase inhibitor 5-Aza-20-deoxycytidine upregulated miR-29b in gastric cancer cells...

Traditional Chinese medication is increasingly used to treat a wide range of human chronic diseases like cardiovascular diseases and cancers. This study was designed to explore whether ka-sai-ping (KSP), a novel traditional Chinese medicine developed by us, prevents gastric cancer growths and to investigate the underlying mechanism. The xenograft model of mouse gastric cancer was established by injecting MFCs into nude mouse subcutaneously. Cell autophagy was assessed by MDC staining. Lysosome and mitochondria were detected by Lyso-Tracker Red and Mito-Traker Green staining...

MicroRNAs (miRNAs) are important regulators of pathobiological processes in various cancer. In the present study, we demonstrated that miR-93 expression was significantly up-regulated in gastric cancer tissues compared with that in matched normal mucosal tissues. High expression of miR-93 was significantly associated with lymph node metastasis and tumor-node-metastasis (TNM) stage. Functionally, ectopic expression of miR-93 promoted cell proliferation, migration, invasion, EMT phenotypes, and repressed apoptosis and G1 cell cycle arrest in vitro, and promoted tumor formation in vivo...
