Effects of Tat on β-catenin-dependent signaling. U87MG were transfected with TOPflash and Renilla luciferase and transfected with Tat cDNA, backbone pcDNA vector, or left untreated. At 24 h post-treatment, dual luciferase activity was measured and normalized as relative light units (RLU) of TOPflash firefly luciferase activity/ Renilla luciferase activity. Data represent a minimum of three experiments. Error bars represent mean +/−standard deviation. Asterisks denote p≤0.05 in comparison to pcDNA transfected cultures
