Figure Lengend Snippet: Figure 3. Effect of miR-423-5p target site overexpression on HSPCs. A, Vector structure. HDAd-GFP-miR-423 contains four miR-423-5p target sites in the 30UTR linked to the GFP gene. B, Mouse HSPCs (M; Lin cells from the bone marrow of CD46-transgenic mice) and human HSPCs (Hu; CD34þ cells) were infected with either HDAd-GFP or HDAd-GFP-miR423 at a multiplicity of infection of 500 or 3,000 vp/cell, respectively. Three days later, cell lysates were analyzed by Western blot analysis for CDKN1A. Blots were reprobed with anti-b-actin antibodies to adjust for loading differences. The right panel shows the quantification of CDKN1A signals normalized to b-actin signals. The signals from the corresponding mouse and human HDAd-GFP/mgmt samples were taken as 100%. C, Effect on progenitor colony formation. One day after HDAd infection, mouse Lin cells (2.5 103 cells per 35 mm dish) or human CD34þ cells (3 103 cells/dish) were plated for colony assays. Colonies were counted 12 days later (N ¼ 3; , P < 0.05). Statistical significance was calculated by two-sided Student t test (Microsoft Excel). [In agreement with previous studies (35, 36), infection of HSPCs at relatively high multiplicities of infection slightly reduced the colony forming capacity of HSPCs.] n.s., not significant.
