Circadian clocks: It's time for chronobiology.

open access: yesPLoS Biology, 2023
Circadian clocks are everywhere, yet we still have not translated the vast knowledge gained in the past 20 years on the properties of circadian clocks into practical applications.

Adaptive Significance of Circadian Clocks

open access: yesChronobiology International, 2003
Circadian clocks are ubiquitous and are found in organisms ranging from bacteria to mammals. This ubiquity of occurrence implies adaptive significance, but to date there has been no rigorous empirical evidence to support this.

Hundreds of LncRNAs Display Circadian Rhythmicity in Zebrafish Larvae

open access: yesCells, 2021
Long noncoding RNAs (lncRNAs) have been shown to play crucial roles in various life processes, including circadian rhythms. Although next generation sequencing technologies have facilitated faster profiling of lncRNAs, the resulting datasets require ...

Computational Analysis Predicts Hundreds of Coding lncRNAs in Zebrafish

open access: yesBiology, 2021
Recent studies have demonstrated that numerous long noncoding RNAs (ncRNAs having more than 200 nucleotide base pairs (lncRNAs)) actually encode functional micropeptides, which likely represents the next regulatory biology frontier.

Real time, in vivo measurement of neuronal and peripheral clocks in Drosophila melanogaster

open access: yeseLife, 2022
Circadian clocks are highly conserved transcriptional regulators that control ~24 hr oscillations in gene expression, physiological function, and behavior.

A broken circadian clock: The emerging neuro-immune link connecting depression to cancer

open access: yesBrain, Behavior, & Immunity - Health, 2022
Circadian clocks orchestrate daily rhythms in many organisms and are essential for optimal health. Circadian rhythm disrupting events, such as jet-lag, shift-work, night-light exposure and clock gene alterations, give rise to pathologic conditions that ...

New Insights Into Cancer Chronotherapies

open access: yesFrontiers in Pharmacology, 2021
Circadian clocks participate in the coordination of various metabolic and biological activities to maintain homeostasis. Disturbances in the circadian rhythm and cancers are closely related.

Organoids as Model Systems to Investigate Circadian Clock-Related Diseases and Treatments

open access: yesFrontiers in Genetics, 2022
Circadian rhythms exist in most cell types in mammals regulating temporal organization of numerous cellular and physiological processes ranging from cell cycle to metabolism.

Balance equations can buffer noisy and sustained environmental perturbations of circadian clocks [PDF]

open access: yes, 2010
We present a new approach to understanding how regulatory networks such as circadian clocks might evolve robustness to environmental fluctuations. The approach is in terms of new balance equations that we derive.

Demyelination Regulates the Circadian Transcription Factor BMAL1 to Signal Adult Neural Stem Cells to Initiate Oligodendrogenesis

open access: yesCell Reports, 2020
Summary: Circadian clocks are endogenous oscillators that generate cell-autonomous rhythms that govern cellular processes and are synchronized by external cues in the local macro- and micro-environments.
