Increased protein expression of nNOS in skeletal muscles from collagen-induced arthritis (CIA) mice and patients with rheumatoid arthritis (RA). The levels of eNOS, iNOS, nNOS in mouse muscles (A) and nNOS in human muscles (B) were determined by western blotting. iNOS was not detected in control (Ctrl) or CIA, but was detected in LPS-stimulated cells (positive control, PC). (C) Mean levels (±SEM) of NOS isoforms were quantified and normalised to the actin content. 4–7 muscles per group. *p<0.05; ***p<0.001 versus controls.
