Research Abstract

Lung cancer easily metastasizes to multiple organs, such as bone, lung, brain, liver, and adrenal gland. We applied microarray analysis to find the gene expression influencing organotropism of lung cancer metastasis. Human lung adenocarcinoma cell lines were used. Cell were cultured on the fresh tissue slice of athymic mouse. After that, proliferated cancer cells were collected from the surface of organ slice and cultured in the flask again. Then the conditioned cells from each organ were obtained. Microarray analysis was applied to these cells including original cells in order to detect specific gene alteration in each organ. Gene expressions of conditioned cells obtained from each organ were compared with original cells. Organ specific alterations were checked using unpaired t-test. We detected 76 genes as adrenal metastasis specific alterations, 22 genes with lung, 212 with liver, 25 with kidney, 141 with bone, and 27 with muscle.
