Eukaryogenesis From FECA to LECA: Radical Steps Along the Way

open access: yesBioEssays, EarlyView.
How did the last eukaryotic common ancestor (LECA) population evolve? Recent evidence shows an Asgard archaeon‐like organism acquiring a bacterium, the future mitochondrion, going from symbiosis to endosymbiosis. I postulate that almost all salient LECA characteristics could have resulted from the ensuing enhanced ATP generation and internal reactive ...

Exploring the potential association and experimental validation of disrupted circadian rhythms with polycystic ovary syndrome via meta-analysis and bioinformatics: a possible pathogenic mechanism

open access: yesFrontiers in Endocrinology
BackgroundPolycystic ovary syndrome (PCOS) has been extensively studied as a common female endocrine disease. In recent years, the relationship between circadian rhythm and PCOS has gradually drawn attention, although the precise nature of this ...

Genetics of Circadian Rhythms

open access: yesNeurologic Clinics, 2019
In mammals, genetic influences of circadian rhythms occur at many levels. A set of core "clock genes" have been identified that form a feedback loop of gene transcription and translation. The core genetic clockwork generates circadian rhythms in cells throughout the body.

Integrating Astrocytes in the Sleep–Wake Cycle: The Time Is Now

open access: yesBioEssays, EarlyView.
Astrocytes actively regulate sleep homeostatic and circadian rheostatic processes, underpinning the sleep–wake cycle. By acting as context‐dependent integrators of internal state and rhythmic environmental inputs, they modulate the encoding properties of neuronal circuitries and contribute to salient temporal representations in the brain.

Targeting Cryptochromes in Chronic Diseases

open access: yesCell Biology International, EarlyView.
ABSTRACT The circadian clock generates 24‐h molecular rhythms through transcription–translation negative feedback loops (TTFLs) and regulates daily physiological processes such as sleep–wake cycles, body temperature, hormone secretion, metabolism, and immune function.

Functional regression with intensively measured longitudinal outcomes: a new lens through data partitioning

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Modern longitudinal data from wearable devices consist of biological signals at high‐frequency time points. Distributed statistical methods have emerged as a powerful tool to overcome the computational burden of estimation and inference with large data, but methodology for distributed functional regression remains limited.

Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Food Effect of Bexicaserin in Healthy Participants: A First‐in‐Human Randomized, Double‐Blind, Placebo‐Controlled Single Ascending Dose Escalation Phase 1 Study

open access: yesClinical Pharmacology in Drug Development, EarlyView.
Abstract Bexicaserin (LP352) is a selective 5‐hydroxytryptamine 2C (5‐HT2C) superagonist in development for the treatment of seizures in developmental and epileptic encephalopathies (DEEs). This double‐blind, placebo‐controlled, single ascending dose (SAD) Phase 1 study aimed to assess the safety, tolerability, and pharmacokinetic (PK) and ...
