| Outline of Final Research Achievements |
To elucidate the molecular mechanisms for the pro-inflammatory effect of ABIN-3, an inhibitor for NF-κB activation, we established the stable transfectant constitutively expressing ABIN-3 by enforced expression in fibroblast-like synoviocyte cell line MH7A derived from rheumatoid arthritis patient designated as A3G. A3G showed the phenotypic changes as spindle-like appearance, growth retardation, decreased expression of MMPs and ALDH1A1, and down-regulated activity of Erk and Akt. We identified E3 ubiquitin ligase NEDD4L as a binding partner of ABIN-3 by mass-spectrometry and enforced expression.
