Phosphorylation and circadian molecular timing

Brenna, Andrea ; Albrecht, Urs

In: Frontiers in Physiology, 2020, vol. 11, p. -

Endogenous circadian rhythms are biological processes generated by an internal body clock. They are self-sustaining, and they govern biochemical and physiological processes. However, circadian rhythms are influenced by many external stimuli to reprogram the phase in response to environmental change. Through their adaptability to environmental changes, they synchronize physiological responses...

Circadian and genetic modulation of visually-guided navigation in Drosophila larvae

Asirim, Ece Z. ; Humberg, Tim-Henning ; Maier, G. Larisa ; Sprecher, Simon G.

In: Scientific Reports, 2020, vol. 10, no. 1, p. 2752

Organisms possess an endogenous molecular clock which enables them to adapt to environmental rhythms and to synchronize their metabolism and behavior accordingly. Circadian rhythms govern daily oscillations in numerous physiological processes, and the underlying molecular components have been extensively described from fruit flies to mammals. Drosophila larvae have relatively simple nervous...
