A Lavandula angustifolia flower extract and dipeptide‐4 blend modulates oxidative, glycative, autophagic and circadian pathways in human skin models

open access: yesInternational Journal of Cosmetic Science, Volume 48, Issue 3, Page 477-488, June 2026.
The blend enhanced antioxidation, anti‐glycation, autophagy and circadian regulation in cell and skin models. Key markers included mitochondrial ROS, γ‐H2AX, AGEs, ATP, melatonin, LC3 and SOD. Significant improvements were visualized via fluorescence and quantified with statistical markers.

Cholecystokinin receptor type A are involved in the circadian rhythm of the mouse retina

open access: yesHeliyon
The retina is the only organ projecting external light to the suprachiasmatic nucleus. Cholecystokinin receptor type A (Cckar/Cckar) is one of the essential factors for light reception in retinal cells. As there was a lack of literature on the matter, we

Identification of sex hormone-binding globulin in the human hypothalamus [PDF]

open access: yes, 2005
Gonadal steroids are known to influence hypothalamic functions through both genomic and non-genomic pathways. Sex hormone-binding globulin ( SHBG) may act by a non-genomic mechanism independent of classical steroid receptors.

Excitatory Actions of GABA in the Suprachiasmatic Nucleus [PDF]

open access: yesThe Journal of Neuroscience, 2008
Neurons in the suprachiasmatic nucleus (SCN) are responsible for the generation of circadian oscillations, and understanding how these neurons communicate to form a functional circuit is a critical issue. The neurotransmitter GABA and its receptors are widely expressed in the SCN where they mediate cell-to-cell communication.

Circadian Deregulation in Multiple Myeloma: BMAL1/CLOCK Expression Patterns and Diagnostic Performance

open access: yesInternational Journal of Laboratory Hematology, EarlyView.
ABSTRACT Background Circadian clock disruption has emerged as a relevant axis in cancer; however, the expression patterns and diagnostic relevance of BMAL1 and CLOCK in multiple myeloma (MM) remain insufficiently defined. Methods BMAL1 and CLOCK mRNA expression was quantified by RT‐qPCR in bone marrow samples from 46 newly diagnosed MM patients and 13 ...

Identification of novel light-induced genes in the suprachiasmatic nucleus

open access: yesBMC Neuroscience, 2007
Background The transmission of information about the photic environment to the circadian clock involves a complex array of neurotransmitters, receptors, and second messenger systems.

Blue Light Exposure During Sleep in Type 1 Diabetes: Impacts on Glycemic Control and Psychosocial Health

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Light exposure at night is linked to increased risk for obesity and insulin resistance in the general population. While sleep health is recognized as a key component of diabetes management, there has been less emphasis on nighttime light exposure. This study aimed to investigate the effects of blue and white light exposure immediately prior to

Loss of ZBTB20 impairs circadian output and leads to unimodal behavioral rhythms

open access: yeseLife, 2016
Many animals display morning and evening bimodal activities in the day/night cycle. However, little is known regarding the potential components involved in the regulation of bimodal behavioral rhythms in mammals.

The VIP-VPAC2 neuropeptidergic axis is a cellular pacemaking hub of the suprachiasmatic nucleus circadian circuit

open access: yesNature Communications, 2020
Circadian activity modulation in the suprachiasmatic nucleus (SCN) is a network-level emergent property that requires neuropeptide VIP signaling, yet the precise cellular mechanisms are unknown. Patton et al.

Prolonged exposure to artificial light and carcinogenesis: A systematic review of oncostatic mechanisms associated with melatonin pathways

open access: yesPhotochemistry and Photobiology, EarlyView.
Exposure to artificial light at night (ALAN), particularly at blue wavelengths, disrupts circadian rhythms by suppressing melatonin, thereby increasing cancer susceptibility. This systematic review consolidates evidence linking prolonged ALAN exposure to an elevated risk of breast and prostate tumors.
