Research Abstract

We developed a new detection system for anti-body against transcriptional factors in connective tissue diseases. Ninety six nuclear factors that involved in cell cycle and homeostasis were blotted on the DEAE paper and incubated with serum from the patients with connective tissue diseases including SLE, dermatomyositis, polyangitis. Anti-HMG1 antibody was detected in 2 patients with polyangitis. Antibody against PCNA was observed in 2 SLE but the serum reacted with a lot of nuclear factors irrelevant with organ specificity. Acetylation and methylation of nuclear factors did not affect on the result of detection of auto-antibody.
