Fresh insights into the light‐induced pineal gland circadian rhythm transmission mechanism derived from mRNA and miRNA profiling

Animal Research and One Health, EarlyView.
Mechanisms of light in regulating the chick pineal clock. Abstract The circadian clock significantly impacts animal health and productivity, with light playing a crucial role in regulating circadian rhythms. However, the mechanisms behind light‐induced circadian transmission remain unclear, particularly in light‐sensitive avian species.

Cryptochrome Interacts With Actin and Enhances Eye-Mediated Light Sensitivity of the Circadian Clock in Drosophila melanogaster

Frontiers in Molecular Neuroscience, 2018
Cryptochromes (CRYs) are a class of flavoproteins that sense blue light. In animals, CRYs are expressed in the eyes and in the clock neurons that control sleep/wake cycles and are implied in the generation and/or entrainment of circadian rhythmicity ...

The Application of Carbon Dots in Crops for Sustainable Agriculture

ChemistryEurope, EarlyView.
Carbon dots serve as versatile nanoagents across the crop life cycle. They promote plant growth and photosynthesis, enhance resilience to biotic and abiotic stresses, aid in postharvest preservation, and enable sensitive detection of contaminants.

Role of Cryptochrome-1 and Cryptochrome-2 in Aldosterone-Producing Adenomas and Adrenocortical Cells [PDF]

International Journal of Molecular Sciences, 2018
Mice lacking the core-clock components, cryptochrome-1 (CRY1) and cryptochrome-2 (CRY2) display a phenotype of hyperaldosteronism, due to the upregulation of type VI 3β-hydroxyl-steroid dehydrogenase (Hsd3b6), the murine counterpart to the human type I 3β-hydroxyl-steroid dehydrogenase (HSD3B1) gene.

Clock gene dysregulation in epilepsy: A systematic review

Epilepsia Open, EarlyView.
Abstract Objective Epileptic seizures show a rhythmic pattern, being more frequent at particular times of the day (e.g., only occurring during sleep), suggesting a role of the circadian rhythm. Clock genes regulate the circadian rhythm and might be involved in the pathophysiology of epilepsy.

Cloning, Identification, and Light Response Analysis of Two Circadian Clock Genes Cryptochrome and Period in Boring Giant Clam Tridacna crocea

Progress in Fishery Sciences
The circadian clock is an intrinsic timing mechanism that has evolved in organisms to adapt to the Earth's periodic diurnal changes. Cryptochrome and Period genes are pivotal in regulating the circadian system.

UV-visible absorption spectrum of FAD and its reduced forms embedded in a cryptochrome protein.

Physical Chemistry, Chemical Physics - PCCP, 2020
Cryptochromes are a class of flavoproteins proposed as candidates to explain magnetoreception of animals, plants and bacteria. The main hypothesis is that a biradical is formed upon blue-light absorption by flavin adenine dinucleotide (FAD). In a protein

Circadian Immunity and Vascular Inflammation in Cardiovascular Disease Chronotherapy Windows: Time for a Re‐Assessment

Med Research, EarlyView.
ABSTRACT Circadian rhythms orchestrate cardiovascular physiology by regulating immune and inflammatory pathways. Disruption of these rhythms profoundly alters vascular homeostasis, thereby promoting the onset and progression of cardiovascular diseases (CVD).

Identification of medaka magnetoreceptor and cryptochromes [PDF]

Science China Life Sciences, 2016
Magnetoreception is a hallmark ability of animals for orientation and migration via sensing and utilizing geomagnetic fields. Magnetoreceptor (MagR) and cryptochromes (Cry) have recently been identified as the basis for magnetoreception in Drosophila. However, it has remained unknown whether MagR and Cry have conserved roles in diverse animals. Here we

Vulnerability to helpless behavior is regulated by the circadian clock component CRYPTOCHROME in the mouse nucleus accumbens

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Depression is one of the most common, disabling, and expensive of all neuropsychiatric disorders. Emerging evidence implicates circadian rhythm abnormalities in the pathophysiology of depression. In particular, the nucleus accumbens (NAc), a
