Histochemical examination of the effects of high-dose 1,25(OH)2D3 on bone remodeling in young growing rats

841 views | Feb 13 2018

Sun J et al. suggested that long-term use of physiologically-high dose calcitriol may result in bone loss through RANKL/RANK/osteoprotegerin and EphrinB2-EphB4 signaling pathways, and that these negative effects could continue after drug withdrawal. Therefore, optimal limits for vitamin D administration need to be established for children and adolescents. [Read the Full Post]
