Research Abstract

Rheumatoid Arthritis(RA) is a chronic inflammatory joint disease and characterized by synovial hyperplasia. We previously cloned E3 ubiquitin ligase, Synoviolin, as a regulatory factor of cell proliferation and suggested that endoplasmic reticulum(ER) associated degradation system via Synoviolin has important roles for overgrowth of synoviocytes. Meanwhile, Peptidyl-Arginine Deiminases 4(PADI4) is identified as the RA-susceptible gene. However functions of citrulinated proteins with PADI are unclear. In this study, I hypothesize that the accumulation of citrullinated proteins in RA synoviocytes could associate for ER stress and explore the crosstalk of ubiquitination and citrullination.
