The Epstein-Barr virus (EBV) is a ubiquitous virus that infects most of the human population. EBV infection is associated with multiple human cancers, including Burkitt's lymphoma, Hodgkin's lymphoma, a subset of gastric carcinomas, and almost all undifferentiated non-keratinizing nasopharyngeal carcinoma. Intensive research has shown that EBV triggers a DNA damage response (DDR) during primary infection and lytic reactivation. The EBV-encoded viral proteins have been implicated in deregulating the DDR signaling pathways...

B-cell non-Hodgkin lymphoma (B-cell NHL) is the second commonest malignancy in the stomach. We determined the distribution of Helicobacter pylori outer membrane protein Q (HopQ) allelic type, cytotoxin-associated gene (cag)-pathogenicity activity island (cag-PAI) and vacuolation activating cytotoxin A (vacA) genes, respectively, in patients with B-cell NHL. We also compared them with their distribution in non-ulcer dyspepsia (NUD). H. pylori was cultured from gastric biopsy tissue obtained at endoscopy. Polymerase chain reaction was performed...

The primary gastrointestinal non-Hodgkin's lymphoma is a rare entity. Burkitt's lymphoma (BL) is an aggressive form of B-cell lymphoma which is endemic in Africa, while in rest of the world non-endemic cases has been reported. Primary gastric BL is extremely rare and only around 53 cases have been reported till now. Here we present the case of a middle-aged male, immunocompetent who presented with anorexia weight loss and diarrhea. His upper gastrointestinal endoscopy and biopsy revealed a large primary gastric Burkitt lymphoma...

The complex diversity of nonpathogenic microbes that colonize the human body, known as microbiota, exert considerable effects on physiological homeostasis, and immune regulation. Helicobacter pylori (H. pylori) is a bacterium that frequently colonizes human stomach and is a major pathogenic agent for peptic ulcer diseases, gastric cancer, and mucosa-associated lymphoid tissue (MALT) lymphoma. Due to its acidic pH and peristaltic movements, the stomach has been considered a hostile environment for most microorganisms, however various commensal microorganisms are capable of colonizing the stomach to form a stomach niche...

BACKGROUND: Non-Helicobacter pylori helicobacters (NHPHs) besides H. pylori infect human stomachs and cause chronic gastritis and mucosa-associated lymphoid tissue lymphoma. Cholesteryl-α-glucosides have been identified as unique glycolipids present in H. pylori and some Helicobacter species. Cholesterol-α-glucosyltransferase (αCgT), a key enzyme for the biosynthesis of cholesteryl-α-glucosides, plays crucial roles in the pathogenicity of H. pylori. Therefore, it is important to examine αCgTs of NHPHs...

A woman in her 70s was diagnosed with a protruding mucosa-associated lymphoid tissue (MALT) lymphoma during a secondary health examination. After eradication of Helicobacter pylori, a biopsy revealed gastric follicular lymphoma (FL) and the lesion was still protruding one year later. (18)F-fluorodeoxyglucose positron emission tomography showed focal nodular hypermetabolic activity, suggesting that FL may have transformed into a diffuse large B-cell lymphoma. Upper gastrointestinal endoscopy, colonoscopy, and capsule endoscopy showed no other lesions in the gastrointestinal tract, and bone marrow biopsy showed no permeation into the marrow...

Atractylenolide II (AT-II) exhibits several biological and pharmacological functions, especially anti-cancer activity as the major sesquiterpene lactones isolated from Atractylodes macrocephala (also named Baizhu in Chinese). However, the effects and mechanisms of AT-II on human gastric cancer remain unclear. Cell Counting Kit-8 (CCK-8) assay, morphological changes, flow cytometry, wound healing assay and Western blot analysis were used to investigate the effects of AT-II on cell proliferation, apoptosis and motility of human gastric carcinoma cell lines HGC-27 and AGS...

Lymphomas are solid tumors of the lymphatic system and these are divided into Hodgkin's and non-Hodgkin lymphoma. Non-Hodgkin tumors may originate from non-nodal tissues such as the gastrointestinal tract and they are considered primary when extranodal involvement is equal to or greater than 75% according to the nodal involvement. Extranodal gastrointestinal lymphomas represent 1% to 4% of tumors of the digestive tract, and 10 to 15% of all non-Hodgkin lymphomas. The stomach is the most common extranodal lymphomas site...

Epstein-Barr virus (EBV) is a causative agent of a variety of lymphomas, nasopharyngeal carcinoma (NPC) and ∼9% of gastric (GC) carcinomas. An important question is whether particular EBV variants are more oncogenic than others but conclusions are currently hampered by the lack of sequenced EBV genomes. Here we contribute to this question by mining whole genome sequences of 201 GCs to identify13 EBV-positive GCs, and assembling 13 new EBV genome sequences; almost doubling the number of available GC-derived EBV genome sequences and providing the first non-Asian EBV genome sequences from GC...

BACKGROUND: Helicobacter pylori is associated with inflammation of different areas, such as the duodenum and stomach, causing gastritis and gastric ulcers leading to lymphoma and cancer. Pathogenic islands are a type of clustered mobile elements ranging from 10-200 Kb contributing to the virulence of the respective pathogen coding for one or more virulence factors. Virulence factors are molecules expressed and secreted by pathogen and are responsible for causing disease in the host. Bacterial genes/virulence factors of the pathogenic islands represent a promising source for identifying novel drug targets...

A reddish depressed lesion was found in the corpus of the stomach of a 56-year-old man. Gastric biopsy showed no findings of MALT lymphoma, including lympho-epithelial lesions. A urea breath test, stool antigen test and serum IgG antibody to Helicobacter pylori test were negative. Magnifying endoscopy using narrow-band-imaging showed no malignant structures. Gastric biopsy specimens were subjected to immunohistochemistry and a PCR, which identified Helicobacter suis infection. Triple therapy with esomeprazole, metronidazole, and amoxicillin was administered for 10 days...

Long non-coding RNAs (lncRNAs) are a group of non-coding RNAs (ncRNAs) >200 nucleotides in length that govern diverse biological processes. Recent evidence suggests that lncRNAs are involved in cancer cell proliferation, apoptosis, invasion, migration, and metastasis. Dysregulation of lncRNAs has been observed in various tumors, and lncRNAs act as oncogenes or tumor suppressors in these malignancies. It has been revealed that lncRNA highly upregulated in liver cancer (HULC) is tightly correlated with a number of cancers such as hepatocellular carcinoma, gastric cancer, colorectal cancer, osteosarcoma, and diffuse large B-cell lymphoma...

Bakuchiol is extracted from Psoralea corylifolia, a member of the Leguminosae family, has been used in Indian Ayurvedic and Chinese traditional medicine, and it possesses an anticancer effect. The primary aim of the present study was to identify the molecular mechanisms underlying the anticancer effect of bakuchiol monoterpenes. Bakuchiol treatment significantly inhibited NUGC3 human gastric cancer cell viability in a concentration dependent manner. In addition, bakuchiol significantly increased the apoptotic cell population in the sub‑G1 phase, and Annexin‑V‑fluorescein isothiocyanate/propidium iodide double staining confirmed the increase in apoptosis...
