Light at Night Disturbs the Circadian Rhythm

Caption

A normal circadian rhythm regulates the genes needed to form the signalling substance VEGF, which in turn is necessary for blood vessel growth (angiogenesis). When light at night disturbs the circadian rhythm, and VEGF cannot be produced –- blood vessel growth is inhibited, which can be seen in the microscope images at right.
