Differential expression of cysteine dioxygenase 1 in complex karyotype liposarcomas.

ABSTRACT: Altered cysteine dioxygenase 1 (CDO1) gene expression has been observed in several cancers but has not yet been investigated in liposarcomas. The aim of this study was to evaluate CDO1 expression in a cohort of liposarcomas and to determine its association with clinicopathological features. Existing microarray data indicated variable CDO1 expression in liposarcoma subtypes. CDO1 mRNA from a larger cohort of liposarcomas was quantified by real time-PCR, and CDO1 protein expression was determined by immunohistochemistry (IHC) in more than 300 tumor specimens. Well-differentiated liposarcomas (WDLSs) had significantly higher CDO1 gene expression and protein levels than dedifferentiated liposarcomas (DDLSs) (P < 0.001). Location of the tumor was not predictive of the expression level of CDO1 m
