Wearable‐Derived Diurnal Alignment Between Physical Activity and Device Temperature Predicts Future Disease and Mortality Risk

Advanced Science, EarlyView.
Wearable‐derived diurnal alignment between physical activity and device temperature, decomposed into 24 h coupling strength (M24), phase deviation (D24), and 12 h harmonic magnitude (M12), is examined in approximately 90,000 UK Biobank participants.

Encapsulated Leptin‐Producing Cells Facilitate Entrainment of Circadian Rhythms in Rodents and Nonhuman Primates

Advanced Science, EarlyView.
A clinically translatable cell line can be engineered to produce leptin, encapsulated in biomaterial and safely implanted to produce and deliver the metabolic regulating protein within the body. Implantation of these encapsulated cells decreases the time it takes for mice and non‐human primates to adjust to circadian disruptions similar to those ...

Identification of the suprachiasmatic nucleus venous portal system in the mammalian brain

Nature Communications, 2021
The first known portal system in the mammalian brain was identified in 1933. Here the authors describe a new portal system between the capillary beds of the Suprachiasmatic Nucleus master clock and a circumventricular organ, enabling humoral signals to ...

UBE3A Dosage Imbalance as a Molecular Framework Linking Angelman Syndrome and Dup15q‐Associated Autism Phenotypes

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT UBE3A is a dosage‐sensitive HECT E3 ubiquitin ligase whose neuronal expression is shaped by genomic imprinting at the 15q11.2‐q13 locus. Opposite directions of UBE3A dosage imbalance contribute to distinct neurodevelopmental phenotypes: loss of maternal UBE3A underlies Angelman syndrome, whereas maternally derived 15q11.2‐q13 copy‐number gains,

Circadian rhythmicity and light sensitivity of the zebrafish brain [PDF]

, 2013
Light is important for entraining circadian rhythms, which regulate a wide range of biological processes. Zebrafish have directly light responsive tissues (Whitmore et al 2000) and are thus a useful vertebrate model for circadian rhythmicity and light ...

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

Arthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

The Role of TASK-3 Two-Pore Domain Potassium Channels in the Entrainment of Mammalian Circadian Rhythms [PDF]

, 2014
In mammals light is the principal timing cue for alignment of physiology to the external environment. Illumination from the unrelenting 24-hour day-night cycle enters the biological system and is communicated to the master pacemaker, the suprachiasmatic

FORMATION OF BIOLOGICAL RHYTHMS IN PRENATAL HUMAN ONTOGENESIS

Неонатологія, хірургія та перинатальна медицина, 2019
The formation of biological rhythms in prenatal period is associated with ontogenesis of suprachiasmatic nucleus of the hypothalamus and pineal gland, activity of micro-RNA and clock genes.

Rest‐activity patterns across development in two mouse models of autism and epilepsy

Epilepsia Open, EarlyView.
Abstract Objective Sleep disturbances are common in individuals with autism spectrum disorder (ASD) and epilepsy and are increasingly recognized as comorbidities that affect disease severity and quality of life. This study investigated rest‐activity patterns across development in two genetic mouse models relevant to ASD and epilepsy: synapsin 2 (Syn2 ...
