Figure 7From: MLN51and GM-CSF involvement in the proliferation of fibroblast-like synoviocytes in the pathogenesis of rheumatoid arthritisMLN51 expression in dendritic cells (DCs) and its effect on the proliferation of immature DCs. (a) MLN51 expression is upregulated only in immature bone marrow-derived dendritic cells (BmDCs) in contrast with bone marrow progenitor cells or mature BmDCs. Total RNA was extracted from each sample with Trizol reagent. RT-PCR was performed with mouse MLN51 primers. (b) BC-1 cells (106) were transfected with 4 μg of mMLN51 siRNA (siRNA(+)) or control siRNA (siRNA(-)). The transfected cells were harvested every day and assessed for their proliferation over a period of 4 days. The results are means ± SD obtained from single experiments performed in triplicate cultures. (c) Total RNA was extracted each day from the transfected BC-1 cell cultures. mMLN51 was assessed in each sample by RT-PCR as described previously with primers. Results in (a) and (c) are representative of three separate experiments.Back to article page
