Conversely, more than-expression of Flagtagged N-CoR in THP-1 cells brought about a down-regulation of Flt3 levels (Fig. 2E).BA/F3 cells transfected with either 2 mg of N-CoR siRNA or two mg of management siRNA by means of electroporation making use of the Amaxa Mobile line Nucleofector Package V (Amaxa, Cologne, Germany). Cells were allowed to recover in IL-3 that contains expansion medium for forty eight hrs to permit for Flt3 receptor expression. Cells were then washed in 16 PBS, and resuspended in IL-3 free culture medium or rm-Flt3 ligand (one hundred ng/ml) (R&D methods, MN, United states of america) supplemented media.
