Abstract:

With the use of genome-wide cDNA microarrays, we investigated the transcriptome profile of the human osteosarcoma Sa OS and U-2 OS cell lines. In all, 1,098 chip entries were differentially regulated in the two cell lines; of these, 796 entries corresponded to characterized mRNAs. The identified genes are mostly expressed in epithelial tissues and localize on chromosomes 1, 10, and 20. Furthermore, signaling cascades for cell cycle, glycolysis, and gluconeogenesis, the p53 pathway, cell communication, and focal adhesion were found to be differently regulated in the two cell lines. The transcriptome profiles reported here provide novel information about the considerable molecular differences between these two widely used human osteosarcoma cell lines. © 2010 Elsevier Inc.
