Abstract |
Here we describe a novel multicolor bioluminescent imaging platform that enables us to simultaneously investigate transcription factor nuclear factor-κB (NF-κB) signalling and apoptosis. We genetically modified the human breast cancer cell line MDA-MB-231 to express green, red, and blue light-emitting luciferases to monitor cell number and viability, NF-κB promoter activity, and to enable specific cell sorting and detection, respectively. Z-DEVD-animoluciferin, the pro-luciferin substrate, was used to determine apoptotic caspase 3/7 activity. We used this multicolored cell line for the in vitro evaluation of natural compounds and in vivo optical imaging of tumor necrosis factor (TNFα)-induced NF-κB activation (Mezzanotte et al., PLoS One 9:e85550, 2014). |
