Rheumatoid arthritis. The two faces of Rsk2 in hyperplastic disease

Nat Rev Rheumatol. 2015 Apr;11(4):203-5. doi: 10.1038/nrrheum.2015.1. Epub 2015 Jan 27.

Abstract

Given the established role of 90 kDa ribosomal S6 kinases (Rsk) in oncogenesis, and the promise of new Rsk-blocking cancer treatments, it is perhaps surprising that Rsk2-mediated inhibition of hyperplasia has now been demonstrated to occur in the arthritic synovium. Does this functional duality make Rsk2 a risky target for the treatment of rheumatoid arthritis?
