Two or three types are often presented in one tumor. The mechanisms to form the different histological types are not clear yet. To elucidate which molecules are related to morphological formation in gastric cancer, we performed microarray analysis of RNA from a formalin-fixed paraffin-embedded gastric cancer specimen which has both tubular adenocarcinoma and poorly differentiated adenocarcinoma. Several genes which showed different expression level between tubular adenocarcinoma and poorly differentiated adenocarcinoma by microarray were selected and confirmed the RNA expression level using qPCR. We focused on HRASLS2 (HRAS like suppressor 2) and created stable cell line expressing HRASLS2. Compare to the control, HRASLS2 expressing cell line showed different cell adhesion and cell growth pattern., 研究課題/領域番号:26860235, 研究期間(年度):2014-04-01 - 2016-03-31, 出典:研究課題「胃癌組織分化に関わる遺伝子の網羅的探索」課題番号26860235 (KAKEN:科学研究費助成事業データベース(国立情報学研究所)) (https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-26860235/26860235seika/)を加工して作成, 金沢大学医薬保健研究域医学系}, title = {胃癌組織分化に関わる遺伝子の網羅的探索}, year = {2016} }
