BACKGROUND RNA interference using short hairpin RNA (shRNA) can mediate sequence-specific inhibition of gene expression in mammalian cells. A vector-based approach for synthesizing shRNA has been developed recently. Overexpression of P-glycoprotein (P-gp), the MDR1 gene product, confers multidrug resistance (MDR) to cancer cells. In this study, we reversed(More)
MicroRNAs (miRNAs) are small noncoding RNAs that participate in a variety of biological processes, and dysregulation of miRNAs is widely associated with cancer development and progression. MiR-378 is frequently downregulated in colorectal cancer (CRC) and colorectal cell lines; however, it has high serum levels. Bioinformatics analysis further deduced that(More)
Synovial sarcoma is a malignant mesenchymal neoplasm that is frequently misdiagnosed as a benign condition because of its small size, slow growth, and well-delineated appearance. Rapid spread and early death occur rarely. Here we report a case of synovial sarcoma of the buttocks presenting with a non-healing wound and rapid progression after local resection(More)
OBJECTIVE To explore the discrepancy proteins in gastric cancer by proteome analysis. METHODS Total proteins of gastric cancer tissues and matched normal gastric epithelial tissues were separated respectively by two-dimensional polyacrylamide gel electrophoresis (2-DE). Mass spectrometry was used to test the differentially expressed proteins. RESULTS(More)
OBJECTIVE To study the selective effect to tumor cells mediated by a recombinant adenoviral vector carrying E2F-1 promoter. METHODS The AdEasy-1 adenoviral vector system was used in this experiment. Several recombinant adenovirus with tumor-targeting E2F-1 promoter were constructed and then the E2F-1 promoter gene was checked by PCR and sequencing. The(More)
The aim of the present study was to investigate the mechanisms of long non-coding RNAs (lncRNAs) in a gastric cancer cell line treated with celecoxib. The human gastric carcinoma cell line NCI-N87 was treated with 15 µM celecoxib for 72 h (celecoxib group) and an equal volume of dimethylsulfoxide (control group), respectively. Libraries were constructed by(More)
