Our previous study demonstrated that the peritoneal stroma environment favors proliferation of tumor cells by serving as a rich source of growth factors and chemokines known to be involved in tumor metastasis. In this study, we investigated the interaction between gastric cancer cells and peritoneal mesothelial cells, and determined the effects of TGF-β1 in this processing. Human peritoneal tissues and peritoneal wash fluid were obtained, which examined by hematoxylin and eosin staining or ELISA for measurements of TGF-β1 levels...

Aberrant expression of Liver X receptor α (LXRα) has been frequently reported in various types of cancers excluding gastric cancer (GC). Moreover, the role of LXRα in human GC has not been previously reported. In this study, we investigated the effect of LXRα down-regulation on invasion and EMT of GC. The expression of LXRα in GC cell lines was detected by real-time PCR. The LXRα siRNA was transiently transfected into GC cells using Lipofectamine™ 2000 reagent. Subsequently, cell invasive ability was evaluated by Transwell assays...

Gastric cancer with pregnancy is rare and usually presents in late and advanced stage. Standard interventions in diagnosing, staging and treatment of cancer may be harmful for the fetus. The treatment of cancer in pregnancy should not differ significantly from the treatment in nonpregnant women. There have been case reports of open gastrectomy for gastric cancer in pregnancy. We present a case of early gastric cancer in a 37-year-old pregnant woman treated with laparoscopic distal gastrectomy with lymph node dissection with no postoperative complications...

Rufy3 is a RUN domain-containing protein that has been associated with gastric cancers; however, the role of Rufy3 in the progression of colorectal cancer (CRC) remains unknown. We demonstrated that Rufy3 expression was higher in 11/12 fresh CRC tissues than in adjacent normal tissues. Rufy3 induced elevated expression and transactivity of four major oncogenes in CRC. Moreover, siRNA-mediated repression of Rufy3 induced G0/G1 cell cycle arrest, and Rufy3 overexpression enhanced CRC cell proliferation in vitro and in vivo...

Certain cell types function as factories, secreting large quantities of one or more proteins that are central to the physiology of the respective organ. Examples include surfactant proteins in lung alveoli, albumin in liver parenchyma, and lipase in the stomach lining. Whole-genome sequencing analysis of lung adenocarcinomas revealed noncoding somatic mutational hotspots near VMP1/MIR21 and indel hotspots in surfactant protein genes (SFTPA1, SFTPB, and SFTPC). Extrapolation to other solid cancers demonstrated highly recurrent and tumor-type-specific indel hotspots targeting the noncoding regions of highly expressed genes defining certain secretory cellular lineages: albumin (ALB) in liver carcinoma, gastric lipase (LIPF) in stomach carcinoma, and thyroglobulin (TG) in thyroid carcinoma...

Helicobacter pylori infection is the major cause of gastric cancer, and removal of H. pylori infection from a population could theoretically decrease the number of cases by about 89%. However, in real-life settings, few studies have reported the effect of screening and treating this pathogen in population-based programs. This is mainly because of the lack of an adequate infrastructure for delivery of systematic screening services to asymptomatic individuals, the lack of standardization to ensure that each subject receives the correct diagnostic testing and antibiotic treatment, and limited resources...

BACKGROUND: Fibrinogen (FIB) is an important source of fibrin, which plays a crucial role in circulating tumor cells (CTCs) extravasation and distant metastasis development. We hypothesize it's stable final product, plasma D-dimer, may be associated with CTCs appearance and can reflect the metastatic phenotype in cancer patients. METHODS: We first verified our hypothesis in different murine gastric cancer metastasis models in vivo, plasma D-dimer and fibrinogen as well as its degradation products were directly examined in three metastasis immune-deficient mouse models and in controls...

Gastric cancer is the fifth (men) and sixth (women) most common cause of cancer-related death in Germany. Despite a declining incidence of distal gastric cancer, the prognosis remains dismal: the 5‑year survival rate ranges between 35% for women and 31% for men. The majority are adenocarcinomas, which occur sporadically, familial or hereditary. Adenomas and intraepithelial neoplasms are considered as precursor lesions. Recently, whole genome sequencing and comprehensive molecular profiling described four molecular subtypes of gastric cancer: Epstein-Barr virus (EBV) positive, microsatellite unstable, chromosomal unstable and genomically stable gastric cancer...
