Research Abstract

A purpose of present study is to elucidate a molecular basis of morphological atypism. This study investigated the proteome modulated by oncogenic KRAS in immortalized airway epithelial cells. We here focused on CLIC4 to investigate its potential involvement in an induction of the morphologic atypism in lung cancers. CILC4 protein levels were reduced in some lung cancer cell lines. The knockdown of CLIC4 in an immortalized airway cell line modulated a cell shape as marked enlargement of cells and nuclei. CLIC4 protein levels tended to be lower in high-grade tumors. These results suggest that the alteration in CLIC4 could induce some morphological atypism of neoplastic cells and could be involved in carcinogenesis of the lung.
