Figure Lengend Snippet: Transactivation activity and downstream target gene expression of p53 protein. (A) Reporter assay of p53 protein. Top panel: sequences of WT and mutated p53 responsive elements in response element (RE; upper) and disrupted response element (dRE; lower) reporter plasmids are indicated. Bottom panel: relative luciferase (Luc) activities in acute lymphoblastic leukemia parental cells (left) and the subline (right) cultured in the presence (+) or absence (−) of 5 μM nutlin‐3a for 6 h. Luminescence produced by Renilla luciferase was used as an internal standard. Error bars indicate SD in triplicate analyses. BAS, basic; CTL, pGL3‐control; dRE, pGL3‐dRE; RE, pGL3‐RE. (B) Changes in the gene expression levels of CDKN2A (upper panel) and PUMA (lower panel). Real‐time RT‐PCR analysis was carried out in parental cells (left) and the subline (right) cultured in the presence or absence of nutlin‐3a at 5 μM for the indicated periods using the ACTB gene expression level as an internal control. Error bars indicate SD in triplicate analyses.
Article Snippet: Renilla luciferase reporter plasmid pTK‐RL (E2231; Promega) was cotransfected as the internal standard.
