A Review of Evidence for the Involvement of the Circadian Clock Genes into Malignant Transformation of Thyroid Tissue [PDF]

open access: yesClocks & Sleep, 2023
(1) Background: In 2013, the results of a pioneer study on abnormalities in the levels and circadian rhythmicity of expression of circadian clock genes in cancerous thyroid nodules was published.

Barley Hv CIRCADIAN CLOCK ASSOCIATED 1 and Hv PHOTOPERIOD H1 Are Circadian Regulators That Can Affect Circadian Rhythms in Arabidopsis. [PDF]

open access: yesPLoS ONE, 2015
Circadian clocks regulate many aspects of plant physiology and development that contribute to essential agronomic traits. Circadian clocks contain transcriptional feedback loops that are thought to generate circadian timing.

The calcineurin-NFAT pathway controls activity-dependent circadian gene expression in slow skeletal muscle [PDF]

open access: yesMolecular Metabolism, 2015
Objective: Physical activity and circadian rhythms are well-established determinants of human health and disease, but the relationship between muscle activity and the circadian regulation of muscle genes is a relatively new area of research.

Research progress on the mutual regulatory mechanism of circadian clock genes and autophagy [PDF]

open access: yesFrontiers in Cell and Developmental Biology
Recent studies have highlighted the intricate relationship between the circadian rhythm, a natural biological process responsive to light and darkness, and autophagy, a mechanism crucial for maintaining cellular homeostasis.

Thyroxine differentially modulates the peripheral clock: lessons from the human hair follicle [PDF]

open access: yes, 2015
The human hair follicle (HF) exhibits peripheral clock activity, with knock-down of clock genes (BMAL1 and PER1) prolonging active hair growth (anagen) and increasing pigmentation.

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

open access: yesPLoS 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

Diurnal oscillations of soybean circadian clock and drought responsive genes. [PDF]

open access: yesPLoS ONE, 2014
Rhythms produced by the endogenous circadian clock play a critical role in allowing plants to respond and adapt to the environment. While there is a well-established regulatory link between the circadian clock and responses to abiotic stress in model ...

Comparative Analysis of Circadian Transcriptomes Reveals Circadian Characteristics between Arabidopsis and Soybean

open access: yesPlants, 2023
The circadian clock, an endogenous timing system, exists in nearly all organisms on Earth. The plant circadian clock has been found to be intricately linked with various essential biological activities. Extensive studies of the plant circadian clock have

Non-circadian expression masking clock-driven weak transcription rhythms in U2OS cells. [PDF]

open access: yesPLoS ONE, 2014
U2OS cells harbor a circadian clock but express only a few rhythmic genes in constant conditions. We identified 3040 binding sites of the circadian regulators BMAL1, CLOCK and CRY1 in the U2OS genome. Most binding sites even in promoters do not correlate

Circadian clock genes, ovarian development and diapause [PDF]

open access: yesBMC Biology, 2010
Insects, like most organisms, have an internal circadian clock that oscillates with a daily rhythmicity, and a timing mechanism that mediates seasonal events, including diapause. In research published in BMC Biology, Ikeno et al. show that downregulation of the circadian clock genes period and cycle affects expression of ovarian diapause in the insect ...
