BACKGROUND Common single-nucleotide polymorphisms (SNPs) in microRNAs (miRNA) have been shown to be associated with susceptibility to several human cancers. We evaluated the associations of three SNPs (rs11614913, rs2910164, and rs3746444) in pre-miRNAs (miR-196a2, miR-146a, and miR-499) with the risk of gastric cancer (GC) and peptic ulcer diseases, and(More)
BACKGROUND Common single-nucleotide polymorphisms (SNPs) in microRNAs (miRNA) have been shown to be associated with susceptibility to several human diseases. We evaluated the associations of three SNPs (rs11614913, rs2910164, and rs3746444) in pre-miRNAs (miR-196a2, miR-146a, and miR-499) with the risk of ulcerative colitis (UC) in a Japanese population.

Interleukin-17A (IL-17A) and IL-17F play a role in tissue inflammation by inducing release of proinflammatory and neutrophil-mobilizing cytokines. We investigated the associations between gastric cancer and polymorphisms of IL-17A (rs2275913, G-197A) and -17F (rs763780, 7488 T/C) genes. The study was performed in 811 subjects (524 without gastric cancer and(More)
Colorectal cancer is one of the leading causes of cancer-related death worldwide. Previous studies have shown that miR-92a has an oncogenic function in several cancers and that its up-regulation is correlated with malignant clinicopathologic behaviors of colorectal cancer. It also has been suggested that circulating miR-92a in patients' plasma can be a(More)
We investigated the association between ulcerative colitis (UC) and polymorphisms of IL-17A (rs2275913, G-197A) and IL-17F (rs763780, 7488T/C) genes. We employed the multiplex PCR-SSCP method to detect gene polymorphisms. Both the numbers of -197A (IL-17A) and 7488T (IL-17F) alleles were significantly correlated to the development of UC. The frequencies of(More)
We examined the expression levels of microRNAs (miRNAs (miRs)) in colorectal tumors (63 cancer specimens and 65 adenoma specimens) and paired non-tumorous tissues. Decreased expression of miR-143 and -145 was frequently observed in the adenomas and cancers tested, compared with miR-34a downregulation and miR-21 upregulation. Expression profiles of miR-143(More)
Effects of rectally injected prostaglandin E2 (PGE2) in rats with dextran sodium sulphate (DSS)-induced colitis were investigated in terms of histopathology, local myeloperoxidase (MPO) activity, local mRNA expression of interleukin-1beta (IL-1beta), tumour necrosis factor-alpha (TNF-alpha) and growth-regulated gene produced/cytokine-induced neutrophil(More)
The RCK gene is a target of the t(11;14)(q23;q32) chromosomal translocation observed in human B-cell lymphoma, and the overexpression of its protein (rck/p54) by the translocation was shown to cause malignant transformation. The rck/p54 protein belongs to the DEAD box protein/RNA helicase family, which has a variety of functions such as translation(More)
Expression of the EP4 receptor, a prostaglandin (PG)E2 receptor subtype, as well as disease suppression by the administration of a selective EP4 agonist (ONO-AE1-329) was investigated in the colorectal mucosa of rats with dextran sodium sulphate (DSS)-induced colitis. Rats were given drinking water containing 3% DSS for 2 weeks. Expression of EP4 receptor(More)
BACKGROUND/AIMS Hyperammonemia causes dysfunction of multiple organs in patients with cirrhosis, including hepatic encephalopathy. Blood ammonia concentrations are monitored with respect to disease progression and efficacy of treatment. Fetor hepaticus, the characteristic breath odor in hepatic encephalopathy has called little quantitative attention to(More)
