          <datacite:description descriptionType="Abstract">研究成果の概要(和文): 胃癌患者の癌化した胃粘膜組織では、ヘリコバクター・ピロリ(H. pylori)感染が高い部位でproteinase-activated receptor-1(PAR1)発現量が増加している傾向が見られ、H.pylori感染による胃癌の発生や進行にとPAR1発現増加が関与する可能性が考えられた。一方、H.pyloriのもつプロテーゼについて種々の細胞を用いて反応性を検討した結果、PAR1、PAR2、PAR4を活性化するプロテアーゼの存在は認められなかった。      研究成果の概要(英文) : In the cancer area of gastric mucosal epithelium from gastric cancer patients, we found a tendency that expression of proteinase-activated ceptor-1(PAR1) was positively correlated with infection levels of Helicobacter pylori (H. pylori), suggesting involvement of increased expression of PAR1 in the development of H. pylori-related gastric cancer. We also determined if H. pylori might possess PAR-activating proteinases in various cell lines. However, we did not find any proteinases that activate PAR1, PAR2 or PAR4, in the H. pylori extracts.</datacite:description>
