Representational difference analysis in a lupus-prone mouse strain results in the identification of an unstable region of the genome on chromosome 11.

ABSTRACT: BXSB mice develop a lupus-like autoimmune syndrome. We have previously identified several intervals that were linked to disease and, in an attempt to characterise lupus susceptibility genes within these intervals, we have sought to isolate differentially expressed genes. Representational difference analysis was used to compare gene expression between BXSB and C57BL/10 mice using spleen and thymus as a source of mRNA. The majority of differentially expressed sequences identified were immunoglobulin and gp70-related sequences, overexpression of these being characteristic of the disease. Among other isolated sequences were a sialyltransferase gene, a mouse tumour virus superantigen gene (Mtv-3), and the virus-related sequence, hitchhiker. In BXSB the sialyltransferase gene not only overexpres
