Abstract
It is commonly accepted that melatonin (N-acetyl-5-methoxytryptamine), the most relevant pineal secretory product, has oncostatic properties in a wide variety of tumors and, especially, in those identified as being hormone-dependent. The objective of the present article is to offer a global and integrative view of the mechanisms involved in the oncostatic actions of this indoleamine. Due to the wide spectrum of melatonins actions, the mechanisms that may be involved in its ability to counteract tumor growth are varied. These include: a) antioxidant effects; b) regulation of the estrogen receptor expression and transactivation; c) modulation of the enzymes involved in the local synthesis of estrogens; d) modulation of cell cycle and induction of apoptosis; e) inhibition of telomerase activity; f) inhibition of metastasis; g) prevention of circadian disruption; h) antiangiogenesis; i) epigenetic effects; j) stimulation of cell differentiation; and k) activation of the immune system. The data supporting each of these oncostatic actions of melatonin are summarized in this review. Moreover, the list of actions described may not be exhaustive in terms of how melatonin modulates tumor growth.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
