Melatonin administration for sleep disorders in traumatic brain injury: A review of the literature

open access: yesThe Journal of the International Society of Physical and Rehabilitation Medicine, 2022
Melatonin is a neurohormone that acts at the suprachiasmatic nucleus to diminish the wake-promoting signal of the circadian clock and induce sleepiness. Exogenous melatonin is available as an over-the-counter supplement to induce sleepiness with 1.3% of ...

Melatonin, Melatonin Receptors and Melanophores: A Moving Story [PDF]

open access: yesPigment Cell Research, 2004
Melatonin (5‐methoxy N‐acetyltryptamine) is a hormone synthesized and released from the pineal gland at night, which acts on specific high affinity G‐protein coupled receptors to regulate various aspects of physiology and behaviour, including circadian and seasonal responses, and some retinal, cardiovascular and immunological functions.

Regulation of L1 expression and retrotransposition by melatonin and its receptor: implications for cancer risk associated with light exposure at night. [PDF]

open access: yes, 2014
Expression of long interspersed element-1 (L1) is upregulated in many human malignancies. L1 can introduce genomic instability via insertional mutagenesis and DNA double-strand breaks, both of which may promote cancer. Light exposure at night, a recently

Recent advances on the mechanisms regulating cholangiocyte proliferation and the significance of the neuroendocrine regulation of cholangiocyte pathophysiology [PDF]

open access: yes, 2013
Cholangiocytes are epithelial cells lining the biliary epithelium. Cholangiocytes play several key roles in the modification of ductal bile and are also the target cells in chronic cholestatic liver diseases (i.e., cholangiopathies) such as PSC, PBC ...

Circadian clocks and breast cancer [PDF]

open access: yes, 2016
Circadian clocks respond to environmental time cues to coordinate 24-hour oscillations in almost every tissue of the body. In the breast, circadian clocks regulate the rhythmic expression of numerous genes.
