Article Abstract:

This article discusses circadian rhythms in fruit fly Drosophila. The data reveal that the circadian clock is composed of multiple feedback loops within the circadian oscillator and involvement of proteins in transmitting environmental cues.

Cycling vrille expression is required for a functional Drosophila clock

Article Abstract:

Results demonstrate that transcription factor vrille is expressed in brain circadian pacemaker cells and cycling of vrille is involved in the function of Drosophila clock. Data also show that vrille regulates the clock's overt functioning by regulating the production of neuroactive peptide hormone pigment dispensing factor.
