Abstract

The objective of this study was to identify genes involved in invasion and metastasis using a rat rhabdomyosarcoma model (SMF-A and RMS-B cell lines). The SMF-A cell line was established from a metastatic nodule of an induced rhabdomyosarcoma in syngeneic F344 rats. Two cell lines with defined metastatic potentials, SMF-Ai and SMF-Da, were cloned from the SMF-A line. The cell line SMF-Ai is tumorigenic, highly invasive and highly metastatic. On the other hand, the revertant line SMF-Da is less tumorigenic, non-invasive and non-metastatic. We have isolated from a SMF-Ai cDNA library eight cDNA clones which are differentially expressed by the metastatic SMF-Ai and the non-metastatic SMF-Da cell line using Northern blot analysis. Five of these clones, smf-4, smf-6, smf-41, smf-42 and smf-44, are overexpressed in the SMF-Da cell line and have homology with beta-2-microglobulin, lactate dehydrogenase, ribosomal protein L38, ribosomal protein S4 and acidic ribosomal phosphoprotein P1, respectively. The three other clones, smf-7, smf-40 and smf-61, are overexpressed in SMF-Ai. Clones smf-40 and smf-61 show significant homology with the human TB3-1 gene and the human fus gene respectively. The clone smf-7 has no significant homology wi...Continue Reading
