mating is initiated by the swarming of males at dusk followed by females flying into the swarm. Here, we show that mosquito swarming and mating are coordinately guided by clock genes, light, and temperature. Transcriptome analysis shows up-regulation of the clock genes () and () in the head of field-caught swarming males. Knockdown of and expression affects and male mating in the laboratory, and it reduces male swarming and mating under semifield conditions. Light and temperature affect mosquito mating, possibly by modulating and/or expression. Moreover, the desaturase gene is up-regulated and rhythmically expressed in the heads of swarming males and regulates the production of cuticular hydrocarbons, including heptacosane, which stimulates mating activity.

Golden camellia species are endangered species with great ecological significance and economic value in the section Chrysantha of the genus Camellia of the family Theaceae. Literature shows that more than 50 species of golden camellia have been found all over the world, but the exact number remains undetermined due to the complex phylogenetic background, the non-uniform classification criteria, and the presence of various synonyms and homonyms; and phylogenetic relationships among golden camellia species at the gene level are yet to be disclosed. Therefore, it is necessary to investigate the divergence time and phylogenetic relationships between all golden camellia species at the gene level to improve their classification system and achieve accurate identification of them.

The abundance and behaviour of all hematopoietic components display daily oscillations, supporting the involvement of circadian clock mechanisms. The daily variations of immune cell functions, such as trafficking between blood and tissues, differentiation, proliferation, and effector capabilities are regulated by complex intrinsic (cell-based) and extrinsic (neuro-hormonal, organism-based) mechanisms. While the role of the transcriptional/translational molecular machinery, driven by a set of well-conserved genes (Clock genes), in nucleated immune cells is increasingly recognized and understood, the presence of non-transcriptional mechanisms remains almost entirely unexplored.

Obesity is a contributing factor that increases the likelihood of developing chronic kidney disease. In recent years, studies have found that light pollution worldwide promoted obesity, which was known to be a consequence of circadian rhythm disruption. Nevertheless, the impact of light pollution on kidney disease associated with obesity remains mostly unknown, and potential processes have been minimally investigated.

Background: Prolonged exposure to LED-light has been associated with impaired sleep quality and pathogenesis of various diseases, including Alzheimer's Disease (AD). Red light therapy has been indicated as a non-invasive way of reducing anxiety, mood and sleep optimization in neurodegenerative disorders but its endogenous mechanisms are insufficiently comprehended. Hence, we assessed the effects of scheduled red-light exposure on clock genes-Bmal1 and Per 1 expression, feacal boli frequency, and anxiety-like responses in prolonged LED-light exposed rats.

Background: Alcohol Use Disorder (AUD) affects over 15 million individuals in the United States, contributing to oxidative stress, neuroinflammation, and elevating the risk of neurodegeneration. Despite this, the connection between AUD and aging conditions, particularly Alzheimer's disease (AD), remains unclear. AD, with a heritability of 60-80%, is genetically linked, necessitating an exploration of the molecular implications of AUD and genetic susceptibility to AD.
