Modeling the effects of cell cycle M-phase transcriptional inhibition on circadian oscillation. [PDF]
Circadian clocks are endogenous time-keeping systems that temporally organize biological processes. Gating of cell cycle events by a circadian clock is a universal observation that is currently considered a mechanism serving to protect DNA from diurnal ...

Thyroxine differentially modulates the peripheral clock: lessons from the human hair follicle [PDF]
The human hair follicle (HF) exhibits peripheral clock activity, with knock-down of clock genes (BMAL1 and PER1) prolonging active hair growth (anagen) and increasing pigmentation.

The Ink4a/Arf locus operates as a regulator of the circadian clock modulating RAS activity. [PDF]
The mammalian circadian clock and the cell cycle are two major biological oscillators whose coupling influences cell fate decisions. In the present study, we use a model-driven experimental approach to investigate the interplay between clock and cell ...

A detailed map of coupled circadian clock and cell cycle with qualitative dynamics validation
Background The temporal coordination of biological processes by the circadian clock is an important mechanism, and its disruption has negative health outcomes, including cancer.

Timing avian long-distance migration: from internal clock mechanisms to global flights [PDF]
Migratory birds regularly perform impressive long-distance flights, which are timed relative to the anticipated environmental resources at destination areas that can be several thousand kilometres away.

CLOCK stabilizes CYCLE to initiate clock function in Drosophila [PDF]
Significance The Drosophila circadian clock controls daily rhythms in physiology, metabolism, and behavior via ∼24-h transcriptional feedback loops. CLOCK requires its heterodimeric partner CYCLE to initiate clock function in canonical groups of brain neurons and peripheral tissues, but Clock

Copper nanowires (CuNWs) with a high aspect ratio of ~2600 have been successfully synthesized by using a facile hydrothermal method. The reductions of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) and methylene blue (MB) to leucomethylene blue (LMB) by ...

Overview of the Circadian Clock in the Hair Follicle Cycle
The circadian clock adapts to the light–dark cycle and autonomously generates physiological and metabolic rhythmicity. Its activity depends on the central suprachiasmatic pacemaker.

Clock gene expression in most organs of the living body exhibits a diurnal rhythm synchronized with the external 24 h light-dark (LD) cycle via circadian pacemaker suprachiasmatic nucleus (SCN).

Minimum criteria for DNA damage-induced phase advances in circadian rhythms. [PDF]
Robust oscillatory behaviors are common features of circadian and cell cycle rhythms. These cyclic processes, however, behave distinctively in terms of their periods and phases in response to external influences such as light, temperature, nutrients, etc.
