MicroRNAs (miRNAs) are short non-coding RNA molecules playing regulatory roles by repressing translation or cleaving RNA transcripts. Dysregulated expression of miRNAs is associated with several diseases, including cancer. In this study, we report that the expression of microRNA-101 (miR-101) is down-regulated in gastric cancer tissues and cells, and(More)
BACKGROUND Several somatic mutation hotspots were recently identified in the telomerase reverse transcriptase (TERT) promoter region in human cancers. Large scale studies of these mutations in multiple tumour types are limited, in particular in Asian populations. This study aimed to: analyse TERT promoter mutations in multiple tumour types in a large(More)
Recent studies have shown that miR-199a-5p plays opposite roles in cancer initiation and progression of different cancer types, acting as oncogene for some cancer types but as tumor suppressor gene for others. However, the role and molecular mechanism of miR-199a-5p in gastric cancer are largely unknown. In this study, miR-199a-5p expression level in(More)
BACKGROUND Although a variety of tumor markers are available for diagnosis of pancreatic cancer, their sensitivity and specificity have not yet been ideal. The aims of this study was to detect a panel of serum tumor markers and to evaluate their significance in the diagnosis and prognosis of pancreatic cancer patients. METHODS Eight serum tumor markers(More)
BACKGROUND Recently, there have been a number of studies on the association between MDM2 (Murine Double Minute 2) 309 polymorphism and ovarian cancer risk. However, the results of previous reports remain controversial and ambiguous. Thus, we performed a meta-analysis to explore more precisely the association between MDM2 309 polymorphism and the risk of(More)
The aim of this study was to explore the clinical significance of neutrophil gelatinase-associated lipocalin (NGAL) in the development and prognosis of gastric cancer. NGAL tumor levels were determined in 333 GC patients by immunohistochemistry. NGAL in blood samples from 63 healthy donors and 60 gastric cancer patients were also determined by enzyme-linked(More)
Recent studies have shown that overexpression of regenerating gene family member 4 (REG4) is associated with the initiation and progression of pancreatic cancer. In our study, we explored the role of REG4 in the invasion of pancreatic cancer. Real-time PCR and Western blot analysis were used to determine REG4 expression in pancreatic cancer cell lines. An(More)
BACKGROUND This study aimed to summarize the potential diagnostic value of serum DKK1 levels in cancer detection. MATERIALS AND METHODS Serum DKK1 was measured using enzyme-linked immunosorbent assay in a case-control study. Then we performed a meta-analysis and the pooled sensitivity, specificity, diagnostic odds ratio, and summary receiver operating(More)
OBJECTIVE To study the effect of angiogenesis inhibitor SU6668 on the growth and metastasis of gastric cancer in SCID mice. METHODS Metastatic model was established by orthotopic implantation of histologically intact human tumor tissue into the gastric wall of SCID mice. Forty-eight mice were randomly divided into four groups, and saline, 5-FU, SU6668,(More)
