Aging, circadian disruption and neurodegeneration: Interesting interplay

Latest facts, Neurodegeneration /

The circadian system is an intricate molecular network of coordinating circadian clocks that organize the internal synchrony of the organism in response to the environment. These rhythms are maintained by genetically programmed positive and negative auto-regulated transcriptional and translational feedback loops that sustain 24-hour oscillations in mRNA and protein components of the endogenous circadian clock.

Circle(s) of Life: The Circadian Clock from Birth to Death

Latest facts /

Most lifeforms on earth use endogenous, so-called circadian clocks to adapt to 24-h cycles in environmental demands driven by the planet’s rotation around its axis. Interactions with the environment change over the course of a lifetime, and so does regulation of the circadian clock system. In this review, we summarize how circadian clocks develop in

Melatonin and Prostate Cancer: Anti-tumor Roles and Therapeutic Application

Cancer, Latest facts /

Melatonin is an endogenous indoleamine that has been shown to inhibit tumor growth in laboratory models of prostate cancer. Prostate cancer risk has additionally been associated with exogenous factors that interfere with normal pineal secretory activity, including aging, poor sleep, and artificial light at night. Therefore, we aim to expand on the important epidemiological evidence,

Can Melatonin Be a Potential “Silver Bullet” in Treating COVID-19 Patients?

Basic facts, Viral diseases /

The therapeutic potential of melatonin as a chronobiotic cytoprotective agent to counteract the consequences of COVID-19 infections has been advocated. Because of its wide-ranging effects as an antioxidant, anti-inflammatory, and immunomodulatory compound, melatonin could be unique in impairing the consequences of SARS-CoV-2 infection.

Melatonin: action as antioxidant and potential applications in human disease and aging.

Basic facts, Cancer, Cardiovascular system, Metabolism, Viral diseases /

This review aims at describing the beneficial properties of melatonin related to its antioxidant effects. Oxidative stress, i.e., an imbalance between the production of reactive oxygen species and antioxidant defences, is involved in several pathological conditions such as cardiovascular or neurological disease, and in aging. Therefore, research for antioxidants has developed. However, classical antioxidants often failed to exhibit beneficial effects, especially in metabolic diseases.
