Glycosyltransferases in different brain regions during chick embryo development
No full textGlycosphingolipids, in particular gangliosides, play a crucial role in neuronal development and are known to change dramatically in total content and distribution in different brain areas during embryogenesis. In the present work we analyzed the activity of enzymes involved in the metabolism of gangliosides, at different periods of functional maturation in different regions of chick embryo brain. Our data demonstrate differences in the enzymatic activities in the examined areas; these differences might be correlated with the functional lateralization occurring in the brain during development. Significative differences were found in glycosphingolipid composition between controlateral cerebral hemispheres and optic lobes; these results together with previous data we found, contribute to reinforce our hypothesis on the occurrence of biochemical lateralization during early brain development
Melatonin : circadian rhythm regulator, chronobiotic, antioxidant and beyond
No full textFor many years, melatonin has been known to interact with circadian rhythms. New evidence indicates that melatonin acts as a free radical scavenger and antioxidant. Moreover, melatonin prevents apoptosis in different types of cells, because it induces mRNA levels of several antioxidant enzymes. It is evident that melatonin is involved in the cellular bioenergetic system as a mechanism that counteracts the progression of Alzheimer''s disease
