Cholangiocarcinoma (CCA) is one of the most aggressive malignancies with increasing worldwide incidence and is characterized by unfavorable prognosis due to its early invasive characteristics and poor response to chemotherapy or radiotherapy. Accumulating evidence has indicated that aberrantly expressed circular RNAs (circRNAs) are involved in cancer development and progression. However, their clinical values and biological roles in CCA remain unclear. Hsa_circ_0001649, a novel cancer-related circRNA, has been previously reported to be downregulated in hepatocellular carcinoma and gastric cancer...

Gastric carcinoma (GC) is a common gastrointestinal malignancy with high incidence and mortality worldwide, and most patients are diagnosed in the late stages of disease. Palliative chemotherapy provides a survival benefit for patients with inoperable advanced GC. However, elderly patients who are unable to tolerate chemotherapy had worse prognosis due to lack of effective treatment. Herein we reported a Chinese elderly GC patient using next generation sequencing (NGS)-based tumor DNA analysis. Valuable gene variants of vascular endothelial growth factor (VEGF) A gene amplification were detected...

Post-transplant lymphoproliferative disorders (PTLDs) are life-threatening complications of solid-organ transplantation and bone marrow transplantation leading to a high mortality. PTLD represents a heterogeneous group of lymphoproliferative diseases. They become clinically relevant because of the expansion of transplantation medicine together with the development of potent immunosuppressive drugs associated now with long survival. The risk of PTLD is highest in the early post-transplant period, but the cumulative risk increases with time...

Signet-ring morphology is recognized throughout the gastrointestinal tract. However, this pattern may be observed in other primary sites giving rise to diagnostic challenges in the work-up of metastases. Relatively newer immunohistochemical markers have not been evaluated in this context. We assessed expression patterns of several common immunohistochemical markers in tumors with signet-ring morphology to delineate a pragmatic approach to this differential diagnosis. Primary breast and gastrointestinal carcinomas showing signet-ring features were reviewed...

A hybrid pharmacophore approach was adopted to design and synthesize new series of pyridone-thiazole hybrid compounds. The structures of the compounds were established by IR, 1H NMR, 13C NMR, and HRMS. All the newly prepared compounds (3a-3m) were in vitro evaluated for their antiproliferative activity against three human cancer cell lines, namely Colon cancer (HCT-116), gastric carcinoma (MGC803) and hepatocellular cancer (Huh7). Bioassay results demonstrated that most of the tested compounds showed potent anti-tumor activities against various cancer cells in vitro, and some compounds exhibited stronger effects than positive control 5-Fluorouracil (5-FU)...

BACKGROUND: Resveratrol is a natural polyphenolic compound and its anticancer effect has been receiving considerable attention. Previous studies showed that resveratrol could inhibited the growth of human gastric carcinoma cells and apoptosis induction was an important mechanism. However, whether mitochondrial pathway was involved in resveratrol-induced apoptosis in human gastric cancer was not very clear. METHODS: The cells were examined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay, Annexin V/PI staining assay, mitochondrial membrane depolarization, cell morphological assessment, cytochrome c release assay, and Western blotting assay...

Human DEAD-box RNA helicase gene DDX6 was cloned from B-cell lymphoma cell line RC-K8. Previously, we reported that DDX6 acts as oncogene in several cancers such as colorectal cancer and hepatocellular carcinoma. However, the detailed mechanism of DDX6 action in carcinogenesis is largely unknown. In this study, we examined the functions of DDX6 in clinical gastric cancer (GC) samples and GC cells. DDX6 protein expression levels of cancer samples were higher than those of the adjacent normal tissues in 25 clinical GC samples (median value: 1...

Helicobacter pylori (H.pylori), is a major causative agent of chronic gastritis, gastric carcinoma and duodenal ulcer. Remarkably, H.pylori carries cytotoxin-associated gene pathogenicity island (CagPAI) which encodes a type IV secretion system (T4SS). T4SS is capable of forming a syringe-like structure to deliver oncoprotein cytotoxin-associated Antigen (CagA) into gastric epithelial cells and resulting in a cascade of events in host cells, such as induction of pro-inflammatory cytokines, alteration of cellular gene expression and cytoskeletal rearrangements...
