OBJECTIVES To investigate the association of a non-synonymous single-nucleotide polymorphism (SNP) in DNASEI with susceptibility to systemic lupus erythematosus (SLE) and the production of autoantibodies to nuclear antigens. METHODS The Gln244Arg (rs1053874) SNP was studied in 276 SLE patients and in 368 healthy controls of Spanish ancestry. Its(More)
Poly(ADP-ribose) polymerase-1 (PARP-1) is a nuclear DNA-binding protein that participates in the regulation of DNA repair and maintenance of genomic integrity. In addition, PARP-1 has a role in several models of inflammation disease, where its absence or inactivation confers protection. The aim of this study was to analyze the impact of selective PARP-1(More)
OBJECTIVES To investigate the effect of poly(ADP-ribose) polymerase (PARP) inhibition on the production of inflammatory mediators and proliferation in tumour necrosis factor (TNF)-stimulated fibroblast-like synoviocytes (FLS) from patients with rheumatoid arthritis (RA). METHODS Cultured FLS from patients with RA were treated with two PARP inhibitors,(More)
