Circadian Clocks: The Tissue Is the Issue [PDF]

Current Biology, 2014
The circadian clock uses a widely expressed pair of clock activators to drive tissue-specific rhythms in target gene expression. A new study sheds light on this tissue specificity by showing that binding of clock activators and tissue-specific transcription factors to closely associated target sites enables cooperative activation of target genes in ...

Rapid and Noninvasive Early Detection of Lung Cancer by Integration of Machine Learning and Salivary Metabolic Fingerprints Using MS LOC Platform: A Large‐Scale Multicenter Study

Advanced Science, EarlyView.
Salivary metabolic signatures associated with lung cancer are systematically characterized through a self‐developed high‐throughput mass spectrometry Lab‐on‐a‐Chip platform. Utilizing these metabolic fingerprints, SalivaMLD, an integrated machine‐learning‐driven classification model is developed and demonstrates superior performance in detecting lung ...

Bacterial Capture‐Killing Capsules with Remodeling Bone Immune Microenvironment for the Effective Treatment of Osteomyelitis

Advanced Science, EarlyView.
The PC‐O@TOB capsules are designed to exhibit bactericidal effects, regulate the bone immune microenvironment by promoting M2 macrophage polarization, eliminate excessive ROS, and enhance bone regeneration, providing a novel multi‐dimensional approach for the treatment of osteomyelitis.

Circadian Clock, Cell Division, and Cancer: From Molecules to Organism

International Journal of Molecular Sciences, 2017
As a response to environmental changes driven by the Earth’s axial rotation, most organisms evolved an internal biological timer—the so called circadian clock—which regulates physiology and behavior in a rhythmic fashion.

CCDC80 Protects against Aortic Dissection and Rupture by Maintaining the Contractile Smooth Muscle Cell Phenotype

Advanced Science, EarlyView.
Aortic dissection (AD) is accompanied by a decrease in CCDC80 in vascular smooth muscle cells (VSMCs). CCDC80 can interact with JAK2, and VSMC‐specific CCDC80 deficiency accelerates the progression of AD by activating the JAK2/STAT3 pathway involved in regulating the phenotype switching and function of VSMCs.

Effect of H₂S on the circadian rhythm of mouse hepatocytes

Lipids in Health and Disease, 2012
Background Dysregulation of circadian rhythms can contribute to diseases of lipid metabolism. NAD-dependent deacetylase sirtuin-1(SIRT1) is an important hub which links lipid metabolism with circadian clock by its deacetylation activity depends on ...

Circadian clock and cardiovascular disease [PDF]

Journal of Cardiology, 2011
Both the physiological and pathological functions of cardiovascular organs are closely related to circadian rhythm, an endogenously driven 24-h cycle. Heart rate, blood pressure, and endothelial function show diurnal variations within a day. The onset of cardiovascular disorders such as acute coronary syndrome, atrial arrhythmia, and subarachinoid ...

A Touch Enabled Hemodynamic and Metabolic Monitor

Advanced Science, EarlyView.
This work presents a touch‐based hybrid platform for simultaneous monitoring of vital signs and sweat metabolites. With a simple tri‐finger touch of 4–6 min, users can concurrently get to know their glucose, uric acid, cortisol levels from fingertip sweat, along with blood pressure and heart rate.

Feeding period restriction alters the expression of peripheral circadian rhythm genes without changing body weight in mice. [PDF]

PLoS ONE, 2012
Accumulating evidence suggests that the circadian clock is closely associated with metabolic regulation. However, whether an impaired circadian clock is a direct cause of metabolic dysregulation such as body weight gain is not clearly understood. In this

Protein sequestration versus Hill-type repression in circadian clock models [PDF]

arXiv, 2016
Circadian (~24hr) clocks are self-sustained endogenous oscillators with which organisms keep track of daily and seasonal time. Circadian clocks frequently rely on interlocked transcriptional- translational feedback loops to generate rhythms that are robust against intrinsic and extrinsic perturbations.
