Calcitriol 生物活性

描述

VDR (vitamin D receptor), as a member of the nuclear receptor superfamily, mediates the biological activity of 1,25-dihydroxyvitamin D3 (calcitriol) which is generated from vitamin D by successive hydroxylations in the liver and kidney. VDR can regulate a variety of illnesses in intestine, kidney, bone, skin, heart, and various other organs^[3]. Calcitriol, the most biologically active metabolite of vitamin D, is a non-selective VDR agonist with IC₅₀ of 0.4 nM. Calcitriol is a potent inhibitor of PHA (phytohemagglutinin)-induced lymphocyte proliferation, achieving 70% inhibition of tritiated thymidine incorporation after 72 h in culture. Furthermore, calcitriol suppresses interleukin-2 (IL-2) production by PHA-stimulated peripheral blood mononuclear cells in a concentration-dependent fashion^[4]. In HL-60 cells, a human myelomonocytic leukemia cell line, calcitriol arrests cells in G1; this effect is mediated through an increase in p27. Calcitriol mediated arrest in G0/G1 is also observed in human breastcancer lines. In vivo, a decrease in tumor volume induced by calcitriol correlates with a significant decrease in the intratumoral p21 expression^[5].

溶解方案

细胞实验：

DMSO: 105 mg/mL(252.02 mM)，配合低频超声助溶，注意：DMSO长时间开封后，会吸水并导致溶解能力下降，请避免使用长期开封的DMSO

无水乙醇: 100 mg/mL(240.02 mM)，配合低频超声助溶，注意：无水乙醇开封后，易挥发，也会吸收空气中的水分，导致溶解能力下降，请避免使用开封较久的乙醇

动物实验：请根据您的动物给药指南选择适当的溶解方案。
以下溶解方案都请先按照体外实验的方式配制澄清的储备液，再依次添加助溶剂：
——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议现用现配，当天使用；以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶
