Vitamin D₃ initiated rapid extracellular signal-related kinase (ERK) phosphorylation, but the contribution of vitamin D receptor (VDR) to this event is unclear. We investigated the use of RNA interference (RNAi) to knockdown VDR. RNAi downregulated VDR as well as its targeted gene expression, but vitamin D₃ dependent ERK phosphorylation remained. Thus VDR might not be involved in ERK phosphorylation by vitamin D₃.
