Research Abstract

ヒト胃印環細胞癌株であるKATO-III細胞は、抑制性神経伝達物質であるγ-アミノ酪酸(GABA)の産生酵素であるグルタミン酸脱炭酸酵素(GAD)およびGABA A受容体を発現していた。今回の検討ではGABAがKATO-III細胞の増殖能および浸潤能に及ぼす影響を調べた。(1) GABAおよびGABA A受容体アゴニストの投与によりKATO-III細胞の増殖能の亢進がみられた。またGABAの投与は、MAP kinaseのうちERK1/2のリン酸化の増強およびサイクリンD1の発現増強がみられた。一方、GABAはKATO-III細胞の浸潤能に対して影響は及ぼさなかった。またmatrix metalloprotease-2,9の産生能に対しても影響を与えなかった。
