Circadian rhythms: Eyes of the clock
The daily light-dark cycle synchronizes the internal circadian clock with the outside world. Blind organisms maintain this light-induced entrainment, suggesting the existence of a non-visual phototransduction pathway. The photoreceptor is unknown, but several intriguing candidates have recently come to light.
متن کاملCircadian Rhythms: Hijacking the Cyanobacterial Clock
Using basic research to advance a practical application, a recent study demonstrates that the circadian clock in cyanobacteria can be 'reprogrammed' to improve yields of heterologous protein production - a green future surely beckons.
متن کاملCircadian Clock Proteins in Prokaryotes: Hidden Rhythms?
Circadian clock genes are vital features of eukaryotes that have evolved such that organisms can adapt to our planet's rotation in order to anticipate the coming day or night as well as unfavorable seasons. This circadian clock uses oscillation as a timekeeping element. However, circadian clock mechanisms exist also in prokaryotes. The circadian clock of Cyanobacteria is well studied. It is reg...
متن کاملCircadian Rhythms: Perturbing a Food-Entrained Clock
When food is scarce, a food-entrainable circadian clock coordinates mammalian activity rhythms with a predictable daily mealtime. Neural and molecular substrates of this circadian function have long eluded localization, but new studies suggest a critical role for a familiar circadian clock gene.
متن کاملCircadian rhythms: Mop up the clock!
All circadian clock genes discovered in Drosophila have mammalian counterparts with extensive sequence homology. Similarities and differences have been identified between insect and mammalian oscillators. Recent studies have shed new light on two mammalian clock components: Mop3 and Per2.
