Xenografts of A549-GpNLuc NSCLC and A549-LKB1-GpNLuc NSCLC cells, where LKB1 protein is a tumor suppressor, were subcutaneously injected into the rear and front flanks of NOD/SCID mice, which were then imaged with bioluminescence imaging (BLI) after i.p. injection of furimazine. This evidence concerns the gene STK11 and neoplasm.
