@techreport{oai:kanazawa-u.repo.nii.ac.jp:00048210, month = {May}, note = {本研究ではNeural EFGL like (NELL)の乳癌における発現および機能解析を行った。乳腺組織ではNELL2は筋上皮細胞, NELL2のレセプターであるRoundabout Guidance Receptor 3 (ROBO3)は乳管上皮および乳癌細胞で発現していた。NELL2とレセプターの反発作用による細胞の住み分けを想定し、in vitroでの細胞移動阻害を確認したところ全長NELL2およびC末欠損型NELL2が乳癌細胞の移動を抑制した。乳癌細胞表面へのNELLの結合は、TSPドメインが関与していた。, In this study, we demonstrated the expression and function of Neural EGFL like (NELL), which is a secretory protein in breast tissues. NELL2 was expressed in the myoepithelial cells, and Roundabout Guidance Receptor 3 (ROBO3), which is one of the receptors of NELL2, was expressed in the luminal epithelial cells and breast cancer cells. From the breast ductal structure that composed inside of the luminal epithelial cells and outside of the myoepithelial cells, we suspected the distribution of these cells by ligand (NELL2)-receptor (ROBO3) repulsion. N-terminal thrombospondin-like (TSP) domain contained constructs were bound the surface of breast cancer cell lines. Full-length NELL2 and c-terminal deleted NELL2 construct suppressed the breast cancer cell migration in vitro, however, TSP domain alone was increased migrated cells. It might be suggested that TSP domain of NELL2 related to the binding on the surface of breast cancer cells, but not enough for the cell repulsive signal., 研究課題/領域番号:16K07165, 研究期間(年度):2016-04-01 - 2019-03-31, 出典:研究課題「癌細胞浸潤を阻害抑制する因子の解明」課題番号16K07165 (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-16K07165/16K07165seika/)を加工して作成}, title = {癌細胞浸潤を阻害抑制する因子の解明}, year = {2019} }
