Are inside these pathways and may very well be explored for diseases like RA. The specific genes which might be differentially methylated will not be necessarily the ones that should be the focus of drug development. As an alternative, more attractive proteins within the pathway that are a lot more amenable to inhibition or modulation could be chosen and accomplish the exact same result.Author information Department of Chemistry and Biochemistry, University of California San Diego, La Jolla, CA, USA. 2Ignyta, Inc., San Diego, CA, USA. 3Division of Rheumatology, Allergy and Immunology, UCSD College of Medicine, La Jolla, CA, USA.Received: 27 February 2013 Revised: 25 April 2013 Accepted: 30 April 2013 Published: 30 April 2013 References 1.
