Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Question: Does induction of CCL13 expression in synovial fibroblasts highlight a significant role of oncostatin M in rheumatoid arthritis?
Answer: In contrast to other prominent cytokines involved in the pathogenesis of RA, OSM can strongly up-regulate the expression of CCL13, a chemokine recently identified in the synovial fluid of patients with RA. Despite potent OSM-induced signal transduction in all types of fibroblasts analyzed, only synovial fibroblasts secreted CCL13, which might be indicative of tissue-specific imprinting of different fibroblasts during development.
yes
