Circadian disturbances are early features of neurodegenerative diseases, including Huntington's disease (HD). Emerging evidence suggests that circadian decline feeds into neurodegenerative symptoms, exacerbating them.

Circadian rhythms and post-transcriptional regulation in higher plants [PDF]
The circadian clock of plants allows them to cope with daily changes in their environment. This is accomplished by the rhythmic regulation of gene expression, in a process that involves many regulatory steps.

Circadian rhythmicity by autocatalysis. [PDF]
The temperature compensated in vitro oscillation of cyanobacterial KaiC phosphorylation, the first example of a thermodynamically closed system showing circadian rhythmicity, only involves the three Kai proteins (KaiA, KaiB, and KaiC) and ATP.

Orchestrated transcription of biological processes in the marine picoeukaryote Ostreococcus exposed to light/dark cycles [PDF]
Background: Picoeukaryotes represent an important, yet poorly characterized component of marine phytoplankton. The recent genome availability for two species of Ostreococcus and Micromonas has led to the emergence of picophytoplankton comparative ...

Nuclear Envelope Protein MAN1 Regulates the Drosophila Circadian Clock via Period
Almost all organisms exhibit ~24-h rhythms, or circadian rhythms, in a plentitude of biological processes. These rhythms are driven by endogenous molecular clocks consisting of a series of transcriptional and translational feedback loops. Previously, we have shown that the inner nuclear membrane protein MAN1 regulates this clock and thus the locomotor ...

Codon usage affects the structure and function of the Drosophila circadian clock protein PERIOD [PDF]
Codon usage bias is a universal feature of all genomes, but its in vivo biological functions in animal systems are not clear. To investigate the in vivo role of codon usage in animals, we took advantage of the sensitivity and robustness of the Drosophila circadian system.

The functions of closely related Myb‐like repressor and Myb‐like activator proteins within the plant circadian oscillator have been well‐studied as separate groups, but the genetic interactions between them are less clear.

Analysis of DNA-Damage Response to ionizing radiation in serum-shock synchronized human fibroblasts. [PDF]
Many aspects of cellular physiology, including cellular response to genotoxic stress, are related to the circadian rhythmicity induced by the molecular clock.

Solving the mystery of human sleep schedules one mutation at a time. [PDF]
Sleep behavior remains one of the most enigmatic areas of life. The unanswered questions range from "why do we sleep?" to "how we can improve sleep in today's society?" Identification of mutations responsible for altered circadian regulation of human ...
