Circadian rhythms of proliferation events in two mouse carcinomas [PDF]

open access: yes, 2015
We studied the index of DNA synthesis (DNAs) of two cellular carcinomas: the hepatocellular ES12a and the mammary TN60 of mice, throughout one circadian cycle.

Analysis of DNA-Damage Response to ionizing radiation in serum-shock synchronized human fibroblasts. [PDF]

open access: yes, 2017
Many aspects of cellular physiology, including cellular response to genotoxic stress, are related to the circadian rhythmicity induced by the molecular clock.

Evaluation of QT Liability for PF‐05251749 in the Presence of Potential Circadian Rhythm Modification

open access: yesCPT: Pharmacometrics & Systems Pharmacology, 2020
PF‐05251749 is a dual inhibitor of casein kinase 1 δ/ε, key regulators of circadian rhythm. As a result of its mechanism of action, PF‐05251749 may also change the heart rate corrected QT (QTc) circadian rhythm, which may confound detection of drug ...

Krüppel-like factor 7 deficiency causes autistic-like behavior in mice via regulating Clock gene

open access: yesCell & Bioscience, 2022
Background Krüppel-like factor 7 (klf7), a transcription factor in the nervous system to regulate cell proliferation and differentiation, has been recently identified as a causal gene for autism spectrum disorder (ASD), but the mechanism behind remains ...

Nerve growth factor, brain-derived neurotrophic factor, and the chronobiology of mood: a new insight into the "neurotrophic hypothesis" [PDF]

open access: yes, 2015
The light information pathways and their relationship with the body rhythms have generated a new insight into the neurobiology and the neurobehavioral sciences, as well as into the clinical approaches to human diseases associated with disruption of ...

DEC1 and DEC2 Crosstalk between Circadian Rhythm and Tumor Progression

open access: yesJournal of Cancer, 2016
Clock genes, major regulators of circadian rhythm, are involved in tumor progression. We have shown that clock genes basic helix-loop-helix (BHLH) transcription factors, differentiated embryonic chondrocyte gene 1 (DEC1/BHLHE40/Sharp2/Stra13) and DEC2 ...

The influence of timeshift on ciradian rhythm of sensitivity to X-irradiation in mice [PDF]

open access: yes, 1984
For two groups of male C3H mice an eastbound transmeridional flight was simulated by inducing a time shift of the L:D schedule of 8 hr. The assumed flight brought about a maxima) reduction of the daily light and dark span, respectively.

Research progress on correlation between circadian rhythm disturbance and work-related musculoskeletal disorders

open access: yes环境与职业医学
Circadian rhythm refers to the 24-hour periodic changes in behavior, physiology, and molecular processes in the human body. Disruptions to the circadian rhythm not only affect mental health but are also associated with various metabolic disorders ...
