What is a VDR?

Virtual Data Rooms (VDRs) are secure and reliable ways to access confidential documents in business transactions. VDRs can be used to perform due diligence during mergers and acquisitions. They also assist companies organize important documents and share them with investors and other stakeholders. VDRs are also used to organize and store invoices, contracts, and other documents, for legal reasons, such as litigation or estate planning.

The active form of vitamin D, 1,25-dihydroxyvitamin D (1,25(OH)2D), binds to the vitamin D receptor (VDR) and retinoid X receptor (RXR) to form heterodimers that act on gene promoter regions known as vitamin D response elements. These genes control the production of proteins involved in a myriad of physiological processes.

The VDR can be located in the glial cells, and subsets of them that comprise the brain. In primary rat hippocampal cultures, immunoreactivity for the VDR was detected in oligodendrocytes. The VDR also appears to be present in human neuroblastoma and astrocytes. Treatment of HL-60 myeloblastleukemia cells with 1,25(OH)2D3 led to monocyte-like differentiation that was accompanied by increased VDR protein levels. This effect was prevented by inhibitors of PI3K and MAPK pathways. In addition, VDR expression was increased in oligodendrocytes treated with 12-O-tetradecanoylphorbol-13-acetate (TPA) to induce megakaryoblastic leukemia cell maturation.
