ING4
, as a novel candidate tumor suppressor gene, has been implicated in several human malignances by tumor growth inhibition and apoptosis enhancement. The mechanism of
ING4
remains largely unknown. The purpose of this study was to investigate the inhibitory tumor growth effects of
ING4
on lung adenocarcinoma, and its mechanism, by
ING4
cDNA transduction into A549 cells. Furthermore, the expression level of
ING4
in lung adenocarcinoma tissues was examined. The expression of
ING4
was markedly reduced in human lung adenocarcinoma tissues. Overexpression of
ING4
can induce growth inhibition in A549 cells both in vitro and in vivo, and also induce up-regulation of p27, down-regulation of cyclinD1, SKP2, and Cox2, and inactivation of the Wnt-1/beta-catenin pathway. Moreover, overexpression of
ING4
can enhance the sensitivity of A549 cells to radiotherapy and chemotherapy. Thus,
ING4
may play an inhibitory role on A549 cell proliferation and tumor growth in lung adenocarcinoma by up-regulation or down-regulation of cell proliferation-regulating proteins such as p27, cyclinD1, SKP2, and Cox2 by means of inactivation of Wnt-1/beta-catenin signaling.
