Circadian regulation of gene expression: at the crossroads of transcriptional and post-transcriptional regulatory networks
(Current Biology Ltd, 2014-08)
Gene expression programs activated in response to, or in anticipation of, environmental changes involve sequential steps, from transcription and RNA processing to nuclear export and translation. Here we review recent ...
(Too many) mathematical models of circadian clocks (?)
(Taylor & Francis Ltd, 2001-02)
Many mathematical models derived from the principles obtained from empirical observations in chronobiology have been proposed and explored. They cover several organisms and phenomena, and utilize quite different formal ...
Circadian chronotypes among wild-captured west Andean octodontids
(Sociedad de Biología de Chile, 2006)
Circadian-rhythm of the endopeptidase 22.19 (ec 3.4.22.19) in the rat-brain
(Marcel Dekker Inc, 1992-08-01)
The endopeptidase 22.19 (EC 3.4.22.19) has been associated with the metabolism of neuropeptides by its ability to convert small enkephalin-containing peptides (8 to 13 amino acids) into enkephalins. In addition, this enzyme ...
Circadian structural plasticity drives remodeling of E Cell Output
(Cell Press, 2020-12-21)
Behavioral outputs arise as a result of highly regulated yet flexible communication among neurons. The Drosophila circadian network includes 150 neurons that dictate the temporal organization of locomotor activity; under ...
Differential Thermoregulatory and Inflammatory Patterns in the Circadian Response to LPS-Induced Septic Shock
(Frontiers Media S.A., 2020-03)
Sepsis is caused by a dysregulated host response to infection, and characterized by uncontrolled inflammation together with immunosuppression, impaired innate immune functions of phagocytes and complement activation. Septic ...
N-nitrosomelatonin enhances photic synchronization of mammalian circadian rhythms
(Wiley, 2013-12)
Most physiological processes in mammals are synchronized to the daily light:dark cycle by a circadian clock located in the hypothalamic suprachiasmatic nucleus. Signal transduction of light-induced phase advances of the ...
Evolution of time-control mechanisms in subterranean organisms: cave fishes under light-dark cycles (Teleostei: Siluriformes, Characiformes)
(Taylor & Francis LTDAbingdon, 2013-08-02)
Subterranean organisms are excellent models for chronobiological studies, yet relatively few taxa have been investigated with this focus. Former results were interpreted as a pattern of regression of circadian locomotor ...
Contribution of non-circadian neurons to the temporal organization of locomotor activity
(Company of Biologists, 2019-01)
In the fruit fly, Drosophila melanogaster, the daily cycle of rest and activity is a rhythmic behavior that relies on the activity of a small number of neurons. The small ventral lateral neurons (sLNvs) are considered key ...
