| Abstract |
We describe a multifluorescence labeling technique for simultaneous detection of mRNA, nuclear DNA, and apoptosis in cultured cells. Digoxigenin-labeled cRNA probes were used to study proto-oncogene expression in rat pleural mesothelial cells undergoing apoptosis following exposure to crocidolite asbestos or hydrogen peroxide (H2O2). Hybridized cRNA probe was detected by immunolocalization with an anti-digoxigenin monoclonal primary and fluorophore-conjugated anti-mouse secondary antibody. Cells undergoing apoptosis were simultaneously identified by the TdT-mediated biotin-dUTP nick-end labeling (TUNEL) method and a streptavidin-conjugated far-red fluorophore, and nuclear DNA was stained with oxazole yellow dimer (YOYO-1). With confocal scanning laser microscopy, we demonstrated increased c-jun mRNA expression within the cytoplasm of both TUNEL-positive and non-apoptotic cells following exposure to either crocidolite asbestos or H2O2. Thus, this technique represents a useful in vivo approach for evaluating apoptosis-associated gene expression with confocal scanning laser microscopy.
