The 'RASor's' edge: Ras proteins and matrix destruction in arthritis.
The shared characteristics of rheumatoid arthritis (RA) and cancer, particularly their unchecked growth and invasive behaviors, have been apparent for some time. However, the molecular mechanisms underlying these similarities are not clear. In a recent issue of Arthritis Research & Therapy, Abreu and colleagues link a well-studied oncogene, Ras, with expression of matrix metalloproteinase-3 (MMP-3) in RA. Their study correlates expression of the Ras guanine nucleotide exchange factor RasGRF1 with MMP-3 expression in RA synovium. They elucidate a potential mechanism of regulation of MMP-3 expression in RA, suggesting a potential target for RA treatment.
