3-bromopyruvate increased the cytotoxicity of E7-specific T in vitro. Luciferase-expressing TC-1 tumor cells were seeded in 24-well plates (5 × 104 cells/well). The following day, the medium was replaced with fresh medium containing 3-BrPA. 24 h later, the media was replaced again, removing 3-BrPA, and 1 × 106 E7-specific CTLs were added to each well. The degree of CTL-mediated killing of the tumor cells is indicated by the decrease of luminescence activity and measured with the IVIS Luminescence Imaging System Series 200 (bioluminescence signals were acquired for 3 mins). Data is represented by mean ± SD of three independent experiments (*p < 0.05)
