Blue Light Receptor PHR2‐Mediated Spectrum Antiviral Immunity

open access: yesAdvanced Science, EarlyView.
Blue light suppresses RBSDV through the blue‐light receptor ZmPHR2, which interacts with ZmISP in chloroplasts to trigger ROS burst and antiviral defense. The viral effector P6 enhances ZmPHR2–ZmISP interaction, alters their distribution, and suppresses ROS.

Circadian Rhythm Disruption Exacerbates Autoimmune Uveitis: The Essential Role of PER1 in Treg Cell Metabolic Support for Stability and Function

open access: yesAdvanced Science
Circadian rhythm plays a critical role in the progression of autoimmune diseases. While our previous study demonstrated the therapeutic effects of melatonin in experimental autoimmune uveitis, the involvement of circadian rhythm remained unclear. Using a

Understanding Biological Mechanisms: Using Illustrations from Circadian Rhythm Research [PDF]

open access: yes, 2012
In many fields of biology, researchers explain a phenomenon by characterizing the responsible mechanism. This requires identifying the candidate mechanism, decomposing it into its parts and operations, recomposing it so as to understand how it is ...

Melatonin Mitigates Doxorubicin‐Induced Cardiotoxicity by Targeting the USP18/PKM2 Axis Without Compromising Antitumor Efficacy

open access: yesAdvanced Science, EarlyView.
Melatonin engages MT1/MT2 receptors to suppress STAT1‐driven USP18 upregulation, thereby redirecting PKM2 ubiquitination from K33‐linked autophagic degradation toward K27‐linked nuclear translocation. This prevents PKM2‐mediated proinflammatory gene expression in the heart, alleviating doxorubicin‐induced cardiotoxicity without compromising antitumor ...

Chronotype and Peripheral Clock Genes: Association With Frailty and Insomnia in Mexican Older Adults

open access: yesAGING MEDICINE, EarlyView.
Chronotype, insomnia, frailty, and peripheral clock gene expression were evaluated in community‐dwelling older adults. Extreme morning chronotype was associated with lower odds of insomnia, whereas women showed higher odds of insomnia. Pre‐frail and frail participants exhibited lower peripheral clock gene expression patterns than robust individuals ...

Automating AI Discovery for Biomedicine Through Knowledge Graphs and Large Language Models Agents

open access: yesAdvanced Intelligent Discovery, EarlyView.
This work proposes a novel framework that automates biomedical discovery by integrating knowledge graphs with multiagent large language models. A biologically aligned graph exploration strategy identifies hidden pathways between biomedical entities, and specialized agents use this pathway to iteratively design AI predictors and wet‐lab validation ...

Impact of Lactobacillus johnsonii on glycemic control and lipid metabolism in type 2 diabetes with circadian disruption

open access: yesScientific Reports
Although most patients with type 2 diabetes mellitus (T2DM) and circadian rhythm disruption have poor blood glucose control, a fraction of patients with T2DM and circadian rhythm disruption who still have good blood glucose control. Previous studies have

The Prognostic Significance of Sleep and Circadian Rhythm for Myocardial Infarction Outcomes: Case-Control Study

open access: yesJournal of Medical Internet Research
BackgroundMyocardial infarction (MI) is a medical emergency resulting from coronary artery occlusion. Patients with acute MI often experience disturbed sleep and circadian rhythm. Most previous studies assessed the premorbid sleep

Metals and Circadian Rhythms [PDF]

open access: yes, 2017
Circadian rhythms describe the behavioral and physiological changes that occur in living organisms in order to attune to a 24 hour cycle of day and night. The most striking aspect of circadian function is the sleep-wake cycle, however many other physiological processes are regulated in 24 hour oscillations, including blood pressure, body temperature ...

Initial Stay Time and Work‐Rest Scheduling During Consecutive Heavy‐Intensity Workdays in Hot Environments in Young and Older Males

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction This study examined initial stay times (IST), defined as the duration of uninterrupted work before core temperature approaches recommended safety limits (38.0°C, ~1.0°C above baseline), and the efficacy of work‐rest cycles during repeated heavy work across consecutive workdays in young and older males.
