An oligogenic architecture underlying ecological and reproductive divergence in sympatric populations

eLife, 2023
The evolutionary trajectories and genetic architectures underlying ecological divergence with gene flow are poorly understood. Sympatric timing types of the intertidal insect Clunio marinus (Diptera) from Roscoff (France) differ in lunar reproductive ...

Circadian Clock Control of Translation Initiation Factor eIF2α Activity Requires eIF2γ-Dependent Recruitment of Rhythmic PPP-1 Phosphatase in Neurospora crassa

mBio, 2021
Circadian clock control of mRNA translation contributes to the daily cycling of a significant proportion of the cellular protein synthesis, but how this is accomplished is not understood.

Crosstalk between vrille transcripts, proteins, and regulatory elements controlling circadian rhythms and development in Drosophila

iScience, 2021
Summary: The vrille (vri) gene encodes a transcriptional repressor required for Drosophila development as well as circadian behavior in adults. Alternate first exons produce vri transcripts predicted to produce a short VRI isoform during development and ...

Cryptochrome 1 mediates light-dependent inclination magnetosensing in monarch butterflies

Nature Communications, 2021
Exactly how some animals use magnetic fields to navigate is a longstanding puzzle. A study using a new behavioural assay and transgenic butterflies finds the cryptochrome gene necessary for inclination-based magnetic sensing, and shows that both antennae

Biological clocks [PDF]

Proceedings of the National Academy of Sciences, 1999
Circadian rhythms describe biological phenomena that oscillate with an ≈24-hour cycle. These rhythms include blood pressure, body temperature, hormone levels, the number of immune cells in blood, and the sleep-wake cycle. In this paper, we will focus on common genes between species that are responsible for determining the circadian behavior ...

A chiming biological clock? [PDF]

Current Biology, 1997
Microscopists are in the unique position of being able to encapsulate great science with a single image. The data may be complex, but the visualization can be breathtaking.Now, Olympus has joined forces with Current Biology to offer a state-of-the-art digital camera for the best photomicrograph.

Assessing the Causal Association between Biological Aging Biomarkers and the Development of Cerebral Small Vessel Disease: A Mendelian Randomization Study

Biology, 2023
Biological aging biomarkers, such as leukocyte telomere length (LTL) and epigenetic clocks, have been associated with the risk of cerebral small vessel disease (CSVD) in several observational studies.

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.

Macrophage Meets the Circadian Clock: Implication of the Circadian Clock in the Role of Macrophages in Acute Lower Respiratory Tract Infection

Frontiers in Cellular and Infection Microbiology, 2022
The circadian rhythm is a biological system that creates daily variations of physiology and behavior with a 24-h cycle, which is precisely controlled by the molecular circadian clock.
