Anticancer activity of vitamin D – molecular mechanisms

Molecular mechanisms of anticancer activity of deoxyelephantopin in cancer cells

BACKGROUND Deoxyelephantopin (DOE) is a natural bioactive sesquiterpene lactone from Elephantopus scaber, a traditionally relevant herb in Chinese and Indian medicine. It has shown promising anticancer effects against a broad spectrum of cancers. METHODS We examined the effect of DOE on growth, autophagy, apoptosis, cell cycle progression, metastasis, and various molecular signaling pathways ...

Anticancer Molecular Mechanisms of Resveratrol

Resveratrol is a pleiotropic phytochemical belonging to the stilbene family. Though it is only significantly present in grape products, a huge amount of preclinical studies investigated its anticancer properties in a plethora of cellular and animal models. Molecular mechanisms of resveratrol involved signaling pathways related to extracellular growth factors and receptor tyrosine kinases; forma...

Molecular mechanisms of vitamin D hyporesponsiveness in renal failure.

Different molecular mechanisms of vitamin D(3) receptor antagonists.

Two structurally different antagonists of the nuclear hormone 1alpha,25-dihydroxyvitamin D(3) [1alpha,25(OH)(2)D(3)], the 25-carboxylic ester ZK159222 and the 26,23-lactone TEI-9647, have recently been described. In this study, the molecular mechanisms and the efficacy of both antagonists were compared. ZK159222 showed similar potency and sensitivity to 1alpha,25(OH)(2)D(3) in ligand-dependent ...

Vitamin D and cancer: a review of molecular mechanisms.

The population-based association between low vitamin D status and increased cancer risk can be inconsistent, but it is now generally accepted. These relationships link low serum 25OHD (25-hydroxyvitamin D) levels to cancer, whereas cell-based studies show that the metabolite 1,25(OH)2D (1,25-dihydroxyvitamin D) is a biologically active metabolite that works through vitamin D receptor to regulat...
