The main enzyme for serotonin degradation, monoamine oxidase (MAO) A, has recently emerged as a key biological factor in the predisposition to impulsive aggression. Male carriers of low-activity variants of the main functional polymorphism of the MAOA gene (MAOA-uVNTR) have been shown to exhibit a greater proclivity to engage in violent acts. Thus, we hypothesized that low-activity MAOA-uVNTR alleles may be associated with a higher risk for criminal violence among male offenders.

Antibodies against the N-terminal (NT) but not the basic domain (BD), DNA binding regions of the largest subunit (S1) of RNA polymerase I (RNAPI) were detected in the sera of MRL-lpr/lpr lupus mice. Antibodies against both RNAPI(S1)-NT and -BD, as well as other systemic lupus erythematosus (SLE) autoantigens (La, ribosomal P proteins and Sm/RNP) were produced by rabbits immunized with anti-DNA antibodies that had been affinity purified from SLE patients. Immunization of nonautoimmune mice (Balb/c) with RNAPI(S1)-NT, RNAPI(S1)-BD, or La in the form of GST fusion proteins, induced production of anti-double-stranded (ds) DNA and anti-Sm/RNP.

Autoantibodies against RNA polymerase I (RNAPI), DNA, La and ribosomal P proteins were detected in the urine of systemic lupus erythematosus (SLE) patients, many with normal protein excretion rates. In a number of cases, the antibodies were detectable in the urine but not the serum sample of the same patient. The presence and relative concentrations of the urinary autoantibodies correlated with disease activity.
