WebAug 24, 2024 · 87 circadian clock-disrupted mice (previously backcrossed onto a C57BL/6J background for 10 generations). Per1/2-null 88 mice have an impaired TTFL clock (Transcription Translation Feedback Loop, which forms the molecular basis of the 89 classical circadian clock) and exhibit no TTFL-driven circadian rhythms in physiology or … WebA different approach to modulating the circadian clock is to target the repressive components of the core TTFL, which consists of the proteins CRY and PER . Inhibition of these proteins is predicted to prolong the transcriptional phase of the clock, whereas agonists would increase the length of the repressive phase.
