Summary: The study identified day-night variations in the cerebellar proteome of mice fed during daytime or nighttime, showing changes in proteins related to heat-shock proteins, enzymes, and neuronal activity in daytime food-restricted mice. Additionally, a significant feeding x time-of-day interaction was found for changes in the intensity of 20 spots.

Summary: Artificial Light At Night (ALAN) disrupts the daily rhythm of oysters by increasing valve activity and eliminating day/night differences in gene expression. The effects of ALAN start at environmentally realistic intensities and can have severe physiological and ecological consequences for oysters.

Summary: The study reveals that ecologically relevant ALAN intensities can affect cricket behavioral patterns, potentially leading to individual level decoupling of locomotion and stridulation behaviors, as well as loss of synchronization at the population level.

Summary: This study demonstrates that cellular triglyceride accumulation exhibits diurnal variations, with differences observed among different cell types. The expression of clock genes and lipid metabolism-related genes also exhibit circadian rhythms. The cellular clock regulates lipid metabolism-related genes to control the circadian rhythms of triglyceride accumulation in each cell type.

Summary: This prospective cohort study suggests that night shift work is associated with incident hypertension, and this association is modified by genetic susceptibility to hypertension. The findings of this study indicate a joint effect of night shift work and genetic risk on hypertension.

Summary: Studies have shown that night shift work has adverse health effects, but the molecular mechanisms behind these effects are not well understood. This study aimed to investigate the association between night shift work and genome-wide DNA methylation changes. Women who worked night shifts exhibited differences in methylation at specific CpG sites compared to non-shift working women. Pathway analysis revealed involvement of circadian rhythm and cellular senescence pathways. Short-term night shift workers showed increased age acceleration, possibly due to adaptation or the healthy worker effect. In conclusion, DNA methylation changes are associated with night shift work, particularly in women.

Summary: The circadian clock plays a crucial role in regulating bone metabolism, including bone loss. Clock-related genes control signaling pathways and transcription factors in osteoblasts and osteoclasts, while also regulating osteocytes and endothelial cells. Furthermore, the regulation of circadian clock genes by novel modulators presents a potential strategy for preventing and treating bone diseases.

Summary: Circadian rhythms play a crucial role in regulating the body's homeostasis, and circadian rhythm disorders can have detrimental effects on metabolic and immune functions. However, the relationship between circadian rhythm disorders and periodontitis has not been well studied. This research aimed to investigate the role of the circadian rhythm control gene BMAL1 in periodontitis. The results showed that downregulation of BMAL1 in circadian rhythm disorder-induced periodontitis led to significant alveolar bone resorption, increased osteoclast differentiation, upregulation of the inflammatory signaling molecule NF-kappa B, elevated apoptosis and oxidative stress levels in periodontal tissues. This study suggests that BMAL1 is a key regulator in periodontitis exacerbated by circadian rhythm disorders, highlighting a potential avenue for periodontitis treatment.

Summary: In organisms with circadian clocks, the post-translational modifications of clock proteins, particularly phosphorylation, play a crucial role in controlling circadian rhythms. Protein phosphatase 4 (PPP4) and its regulatory subunit PPP4R2 have been identified as critical components in mammals and Drosophila, affecting the circadian system by regulating phosphorylation and transactivation activity of CLOCK/BMAL1.

Summary: Mammalian body cells have cell-autonomous and self-sustained circadian oscillators relying on delayed negative feedback loops in gene expression. Transcriptional activation and repression, as well as post-translational mechanisms like phosphorylation and dephosphorylation, play crucial roles in setting the pace of these timekeepers. The study by Klemz and colleagues in Genes & Development demonstrates how dephosphorylation of BMAL1 by protein phosphatase 4 (PPP4) participates in the modulation of circadian timing.

Summary: Regulation of circadian behavior and physiology by the Drosophila brain clock requires communication from central clock neurons to downstream output regions. Morning and evening clock neurons have time-of-day-dependent connectivity to the pars intercerebralis, which is regulated by specific peptides and fast neurotransmitters. This study provides insights into mechanisms by which clock neurons signal to nonclock cells to drive rhythms of behavior.

Summary: Night shift work is associated with an increased risk of cardiovascular and cerebrovascular disease, possibly due to the promotion of hypertension. This study conducted an analysis comparing blood pressure and clock gene expression in internists working day and night shifts. The results showed that night shift work significantly increased night blood pressure and heart rate and disrupted circadian rhythm. The findings suggest that night shifts contribute to higher blood pressure and circadian rhythm misalignment.
