Circadian Regulation of the Na+/K+-Atpase Alpha Subunit in the Visual System Is Mediated by the Pacemaker and by Retina Photoreceptors in Drosophila Melanogaster
Figure 1
α5 immunolabeling of Na+/K+-ATPase α-subunit (ATPα) in the optic lobe of CantonS flies at specific time points under LD 12:12.
The intensity of immunofluorescence in the lamina differs at different time points: A – ZT1, B – ZT4, C – ZT13, D – ZT16. The fluorescence signal is maximal in the lamina and in the medulla neuropils.
