The V325 study showed that docetaxel, cisplatin, and fluorouracil (DCF) prolonged overall survival (OS) of patients with advanced gastric cancer, but with a high incidence of dose-limiting toxicities. We investigated the efficacy and safety of a modified DCF (mDCF) regimen for Chinese patients with advanced gastric cancer. Untreated advanced gastric cancer(More)
AIM To explore the molecular events taking place during human colon cancer development and progression through high-throughput tissue microarray analysis. METHODS We constructed two separate tissue microarrays containing 1.0 mm or 1.5 mm cylindrical samples acquired from 112 formalin-fixed and paraffin-embedded blocks, including carcinomas (n = 85),(More)
BACKGROUND AND AIMS Runx family transcription factors are integral components of transforming growth factor-beta signaling pathways and have been implicated in cell cycle regulation, differentiation, apoptosis, and malignant transformation. The silencing of tumor suppressor genes by aberrant hypermethylation occurs frequently in human cancer. It has been(More)
Ras-association domain family 1A (RASSF1A), a candidate tumor suppressor gene, is frequently silenced and inactivated by hypermethylation of its promoter region in several human tumors. However, the association between RASSF1A promoter methylation and gastric cancer risk remains conflicting. The aim of this study was to assess the association of RASSF1A(More)
Single nucleotide polymorphisms (SNPs) in putative microRNA (miRNA) target sites (miRSNPs) could affect the binding of miRNA with the target and contribute to the susceptibility of human cancers. However, the role of miRSNPs in gastric cancer susceptibility remains largely unknown. Since the over-expression of B7-H1 protein has been reported to be closely(More)
Inhibitory costimulatory molecule CD274 expresses in various cancers and contributes to cancer immune evasion by inhibiting T cell activation and proliferation, yet the regulatory mechanisms for CD274 overexpression in cancers are poorly understood. In this study, we discovered a novel mechanism of CD274 expression regulated by miR-570. A(More)
Spinal cord injury (SCI) is a common outcome of traffic accidents and trauma with severe consequences. There has been no cure for such a condition. We performed experiments to evaluate the feasibility of implanting a chitosan tube filled with semifluid type I collagen into the site of surgically induced SCI to facilitate functional recovery. After a segment(More)
AIM To study the expression of survivin, a novel member of inhibitors of apoptosis protein (IAP) and its significance in colorectal carcinoma. METHODS Survivin mRNA expression was evaluated by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR) in 52 colorectal carcinoma samples and 48 adjacent normal colorectal tissue samples. PCR(More)
AIM To evaluate the diagnostic value of endoscopy in patients with gastrointestinal graft-versus-host disease (GI GVHD). METHODS We identified 8 patients with GI GVHD following allogeneic hematopoietic stem cell trans-plantation (HSCT). GVHD was defined histologically as the presence of gland apoptosis, not explained by other inflammatory or infectious(More)
A gastric cancer cell line, AGS has high-level expression of CD40. CD40 is present on the surfaces of a large variety of cells, including B cells, endothelial cells, dendritic cells and some carcinoma cells, and delivers signals regulating diverse cellular responses, such as proliferation, differentiation, growth suppression, cell death. In this research,(More)
