Molecular cellular mechanisms of peptide regulation of melatonin synthesis in pinealocyte culture
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
This study in rat pinealocyte culture examined the molecular and cellular mechanisms by which the peptides epithalone and vilone regulate melatonin synthesis, focusing on the enzyme arylalkylamine-N-acetyltransferase (AANAT) and the transcription protein pCREB. The abstract reports that epithalone stimulated AANAT and pCREB synthesis and increased melatonin levels in the culture medium, and that adding norepinephrine together with the peptides potentiated AANAT and pCREB expression.
Abstract
The effects of epithalone and vilone peptides on the synthesis of melatonin and factors involved in this process, arylalkylamine-N-acetyltransferase (AANAT) enzyme and pCREB transcription protein, were studied in rat pinealocyte culture. Epithalone stimulated AANAT and pCREB synthesis and increased melatonin level in culture medium. Simultaneous addition of norepinephrine and peptides into the culture potentiated the expression of AANAT and pCREB.
