FLOWERING LOCUS C -dependent and -independent regulation of the circadian clock by the autonomous and vernalization pathways [PDF]
, 2006 Background The circadian system drives pervasive biological rhythms in plants. Circadian clocks integrate endogenous timing information with environmental signals, in order to match rhythmic outputs to the local day/night cycle.

PPAR Research, 2009 In nature, hibernating animals encounter fasting, cold temperature and short day seasonally. Torpor is a state of decreased physiological activity in an animal, usually characterized by a reduced body temperature and rate of metabolism to adapt such a ...

A Targeted Epigenetic Clock for the Prediction of Biological Age
Cells, 2022 Epigenetic clocks were initially developed to track chronological age, but accumulating evidence indicates that they can also predict biological age.

Evaluation of pediatric epigenetic clocks across multiple tissues
Clinical Epigenetics, 2023 Background Epigenetic clocks are promising tools for assessing biological age. We assessed the accuracy of pediatric epigenetic clocks in gestational and chronological age determination.

Rhythms of Locomotion Expressed by Limulus polyphemus, the American Horseshoe Crab: II. Relationship to Circadian Rhythms of Visual Sensitivity [PDF]
, 2008 In the laboratory, horseshoe crabs express a circadian rhythm of visual sensitivity as well as daily and circatidal rhythms of locomotion. The major goal of this investigation was to determine whether the circadian clock underlying changes in visual ...

Identification of the Molecular Clockwork of the Oyster Crassostrea gigas. [PDF]
PLoS ONE, 2017 Molecular clock system constitutes the origin of biological rhythms that allow organisms to anticipate cyclic environmental changes and adapt their behavior and physiology.

A Biological Clock in Drosophila
Cold Spring Harbor Symposia on Quantitative Biology, 1985 The per locus plays a central role in the organization and function of the Drosophila biological clock. The gene has been mapped to a 7-kb DNA segment by physically locating the breakpoints of several chromosomal rearrangements that disrupt per function. This DNA contains a single transcription unit which produces a 4.5-kb poly(A)+ RNA.

Biological clocks in theory and experiments [PDF]
BMC Bioinformatics, 2005 Eukaryotes and some prokaryotes have adapted to the 24 h day/night cycle by evolving circadian clocks. The circadian clock now controls 24-hour rhythms in very many aspects of metabolism, physiology and behaviour. Day-length (photoperiod) measurement depends on the circadian clock, so the 24 h clock mechanism also governs seasonal rhythms, such as ...
