| Research Abstract |
We identified 27 genes suppressed by blockade of AP-1, an oncogenic transcription factor, in lung cancer cells sensitive to the AP-1 blockade using microarray analysis. Among them, knockdown of MCM 4, a component of DNA replication licensing complex, by siRNA reduced cell growth in multiple lung cancer cells. Immunohistochemical analysis in surgically resected lung cancers demonstrated that MCM4 expression was correlated with proliferation markers including Ki-67. MCM4 may play an important role for growth of lung cancers and be a novel molecular target for lung cancer.
