Where this comes from

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?
