Lead perturbs 1,25 dihydroxyvitamin D3 modulation of intracellular calcium metabolism in clonal rat osteoblastic (ROS 17/2.8) cells by Long, G J, Rosen, J F

“…1,25-Dihydroxyvitamin D3 (1,25(OH)2D3) is known to modulate Ca2+ metabolism in several cell types. 1,25(OH)2D3 causes an increase in Ca2+ influx and probably…”
