Exposure to varied 50 nm wavebands allowed identification of waveband specific transcriptional modulation within gene sets representing discrete functional pat hways within Xiphophorus skin. For example, exposure to either 350-400 or 450-500 nm wavebands resulted in opposite transcriptional effects in necrosis and apoptosis gene sets that predict selective differential suppression or activation of these pathways (i.e., 350-400 nm; necrosis suppression, apo ptosis activation, and 450-500 nm; apoptosis suppression, necrosis activation). Further investigation of waveband specific transcription employing successive 10 nm waveband exposures within the genetically responsive 500-550 nm waveband show; (a) greater numbers of genes may be transcriptionally m odulated after 10 nm exposures, than observed for either 50 nm or FL exposures. (b) the 10 nm wavebands incite greater functional specificity than either 50 nm or FL exposures. (c)...
