ABSTRACT
AIM:
The purpose of the present study was to compare microarray gene-expression profiling data between primary central nervous system (CNS) lymphoma and non-CNS lymphomas. MATERIALS ANDMETHODS:
We performed whole-genomic cDNA-mediated annealing, selection and ligation assay with 177 formalin-fixed paraffin-embedded tumor samples.RESULTS:
We identified 20 differentially expressed genes out of which 5 were predominantly expressed in CNS DLBCL compared to non-CNS DLBCL (C16orf59, SLC16A9, HPDL, SPP1, and MAG). SLC16A9 may be involved in aerobic glycolysis of malignant tumors. The alteration in gene expression of SPP1 in primary CNS lymphoma is involved in biological activity, such as CNS tropism, B-cell migration, proliferation, and aggressive clinical behavior. MAG may be an important adhesion molecule that contributes to perineural cancer invasion.CONCLUSION:
Genomic differences between CNS and non-CNS DLBCL exist and the most prominent genes are SPP1 and MAG. SPP1 may play a key role in CNS tropism of primary CNS lymphoma.Palavras-chave
