Inside the former case, since the mRNA expression of the targets does not any change, transcriptomics approach, such as expression array, cannot identify the targets. Recent studies shed light on Retroperitoneal lymph node dissection the fine tuning mechanism of miRNAs in myriad biological processes including growth, tumorigenesis and inflammation. We have recognized enhancement of mir 146a expression in rheumatoid arthritis synoviocyte and macrophages, whilst suppression of them in osteoarthritis. Another group also have identified the enhancement of mir 146a and mir 155 in response to bacterial pathogen such as lipopolysaccaride.

Recently, mice lacking of mir 155 are resistant to collagen induced arthritis, whilst administration of mir 146a complexed with aterocollagen into joint attenuates pathological compare peptide companies issue of CIA. These results indicate that mir 146a and mir 155 plays an important role for developing arthritis and inflammation. However, the targets of both two miRNAs and their molecular mechanisms are not still fully identified. In this study, in order to identify the targets of them in translational level, we established gain of function models using adenovirus and CMV promoter mediated overexpression in several culture models and performed liquid chromatography tandem mass spectrometry based shotgun proteomics in these models.
