The team now hypothesizes that under broad-spectrum daylight conditions, these genes would be subsequently deactivated by wavelengths from a different part of the spectrum — but these additional wavelengths may be absent in fluorescent lighting.
The skin and brain of the three animals, as well as the liver of both fish models all exhibit, increased inflammation and immune responses; however, the mouse liver suppressed this reaction. Overall, the conserved nature of the genetic responses observed, among fishes and a mammal, suggest the presence of light responsive genetic circuitry that is deeply embedded in the vertebrate genome.
