| abstractText | RA175, a new immunoglobulin superfamily member, is preferentially expressed during differentiation of P19 embryonic carcinoma (EC) cells induced by retinoic acid. In the present study, we isolated mouse RA175 cDNA in its entirety and showed that RA175 is the mouse ortholog of TSLC1, a tumor suppressor gene in human lung cancer. RA175/TSLC1 was localized in the adherent region of human lung squamous carcinoma cells and in the differentiated P19 EC cells. RA175/TSLC1 showed homophilic trans-interaction activity in a Ca(2+)-independent manner. RA175/TSLC1 was preferentially expressed in the polarized cells lining the lumen of developing mouse lung epithelium. This suggests that RA175/TSLC1 is a cell adhesion molecule that is acting as a tumor suppressor gene in the metastasis of lung tumors. RA175/TSLC1 may be necessary for cells to remain tightly associated in the epithelium, thereby suppressing metastasis. |
