Abstract
Calcitriol (1, 25-dihydroxyvitamin D3) is the most biologically active metabolite derived from the secosteroid hormone vitamin D. Apart from its calcium homeostatic effects, epidemiological studies have shown that reduced serum calcitriol levels are associated with an increased risk of some types of cancer. Numerous recent epidemiological and experimental studies have reported that it elicits anti-proliferative, apoptotic and differentiation effects in several malignant cell types. The inhibition of calcitriol results in reduced effects of anticancer drugs. Results from a number of clinical trials revealed that sufficient dosing and exposure to calcitriol is critical for achieving antitumor effects during intermittent regimens. This review summarizes the role of calcitriol in anticancer therapy and the progress in understanding its mechanism.
Keywords: Anti-proliferative, apoptosis, calcitriol, cancer prevention, chemotherapeutic agents, clinical trial, differentiation, retinoblastoma, signaling pathways, VDR.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
