...Lisa Wu; Akhilesh B. Reddy Circadian rhythms are a hallmark of living organisms, observable in all walks of life from primitive bacteria to highly complex humans. They are believed to have evolved to co-ordinate the timing of biological and behavioural processes to the changing environmental needs...

...John S. O'Neill; Akhilesh B. Reddy Approximately daily, or circadian, rhythms are ubiquitous across eukaryotes. They are manifest in the temporal co-ordination of metabolism, physiology and behaviour, thereby allowing organisms to anticipate and synchronize with daily environmental cycles. Although...

... of miR - 122 expression is also considered. cancer circadian rhythm hepatitis C virus liver microRNA (miRNA) miR - 122 Circadian rhythms are mechanisms by which an organism anticipates environmental rhythms and changes its physiological or behavioural state accordingly [ 29...

... and differences are reviewed on a molecular and anatomical level. circadian rhythm clock gene clock neuron Drosophila melanogaster pigment-dispersing factor The best-characterized clock protein is PER. So far, PER was isolated from several Dipterean [ 4 , 5 ] and Lepidopterean species [ 6 – 9...

...H.G. Nimmo Crassulacean acid metabolism (CAM) plants exhibit persistent circadian rhythms of CO 2 metabolism. These rhythms are driven by changes in the flux through phosphoenolpyruvate carboxylase, which is regulated by reversible phosphorylation in response to a circadian oscillator. This article...
