Osteosarcoma (OS) is the most commonly diagnosed bone tumor in young adults under
the age of 20. Metastasis is considered an important factor underlying
cancer-associated morbidity and mortality, and, as a result, the survival rate of
patients with metastatic OS is low. In spite of this, the mechanisms underlying
metastasis in OS are currently not well understood. The present study compared
gene expression levels between five non-metastatic and four metastatic OS tumor
samples, using an Affymetrix microarray. A total of 282 genes were differentially
expressed in the metastatic samples, as compared with the non-metastatic samples.
Of these differentially expressed genes (DEGs), 212 were upregulated and 70 were
downregulated. The following DEGs were associated with metastasis: Homeobox only
protein; lysosomal-associated membrane protein-3; chemokine (C-C motif)
ligand-18; carcinoembryonic antigen-related cell adhesion molecule-6; keratin-19;
prostaglandin-endoperoxide synthase-2; clusterin; and nucleoside diphosphate
kinase-1. Subsequently, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and
Genomes (KEGG) enrichment pathway analyses were conducted, which identified 529
biological processes (P<0.01) and 10 KEGG pathways (P<0.05) that were
significantly over-represented in the metastatic samples, as compared with the
non-metastatic samples. Interaction networks for the DEGs were constructed using
the corresponding GO terms and KEGG pathways, and these identified numerous genes
that may contribute to OS metastasis. Among the enriched biological processes,
four DEGs were consistently over-represented: Jun proto-oncogene, caveolin-1,
nuclear factor-?B-inhibitor-? and integrin alpha-4; thus suggesting that they may
have key roles in OS metastasis, and may be considered potential therapeutic
targets in the treatment of patients with OS.
