Although OVX mice and sham-operated mice had different arthritis responses following DCA treatment, we did not find any difference between the OVX group and the sham group in regard to level of IL-6 (OVX: median 76 pg/mL, range 20 to 1,032 pg/mL versus sham: median 111.2 pg/mL, range 30 to 348.2 pg/mL) and anti-CII antibodies (optical density: OVX: median 0.91, range 0.37 to 1.32 versus sham: median 0.84, range 0.30 to 1.69). The gene discussed is IL6; the disease is Arthritis.
