title: In Silico Analysis of Lanostanoids Characterized in Ganoderma Mushrooms (Agaricomycetes) as Potential Ligands of the Vitamin D Receptor.
abstract: The metabolism of vitamin D is a very important pathway involved in the regulation of sterols and maintenance of cell health. The physiological activity of the human hormone 1α,25-dihydroxyvitamin D3, or calcitriol, is mediated by the vitamin D receptor (VDR), an endocrine member of the nuclear receptor superfamily that inhibits cell growth and stimulates cell differentiation, suggesting a potential application in cancer chemoprevention. Since nonpolar extracts obtained from Ganoderma mushrooms have also been shown to exert an antiproliferative effect on several cancer cell lines, it was suggested that at least part of its activity might be mediated by VDR. The aim of this work was to identify possible VDR ligands from an extensive library of lanostanoids isolated from several Ganoderma mushrooms. Using an in silico approach, 30 lanostanoids were found to interact with the VDR ligand-binding pocket in the same way as calcitriol. The possible implications of using these compounds are discussed here.
