Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Exploring the gut–kidney axis: possible connection between gastrointestinal and renal disorders in dromedary camels

open access: yesFrontiers in Veterinary Science
IntroductionGastrointestinal (GI) disorders and renal dysfunction are common and clinically significant conditions in dromedary camels (Camelus dromedarius). However, their interrelationship—representing the gut–renal axis—remains poorly understood. This

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Cryomicroneedle Arrays for Biotherapeutics Delivery

open access: yesSmall Science
Biotherapy offers a promising approach for treating a variety of diseases. However, the lack of advanced delivery systems remains a significant barrier to improve the efficacy, safety, and cost‐effectiveness of biotherapeutics.

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization

open access: yesFEBS Letters, EarlyView.
CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Metabolic regulation of regulatory T cells: mechanisms, heterogeneity, and implications in disease

open access: yesFrontiers in Immunology
Regulatory T (Treg) cells are essential for maintaining immune tolerance, preventing autoimmune responses, and supporting tissue repair. Tregs employ a flexible and diverse metabolic program that includes glycolysis, oxidative phosphorylation (OXPHOS ...
