Background: vitamin d is an important steroid that can regulate bone metabolism including osteoclast (oc) differentiation. transient receptor potential cation channel subfamily v member 5 (trpv5), is a calcium channel protein involved in oc differentiation. however, the impact of vitamin d on trpv5 expression during oc differentiation is not clear. objectives: to determine if 1,25-dihydroxyvitamin d3 (1,25(oh)2d3) regulates the expression of trpv5 during oc differentiation. methods: bone marrow mononuclear macrophage (bmms) were induced to differentiate intoocwith or without treatment with 10 nm1,25(oh)2d3. the expression levels of vitamin d receptor (vdr) and trpv5 were examined. the expression of several oc markers, including tartrate resistant acid phosphatase (trap), carbonic anhydrase ii (ca ii), cathepsin k (ctsk), and vacuolar-type h+-atpase (v-atpase) were also detected. results:we found that thevdrwas expressed in murine bonemarrow-derived macrophages at the early stage of ocdifferentiation. trpv5 expression was increased during oc differentiation, which was down-regulated by 1,25(oh)2d3 after a prolonged exposure. the 1,25(oh)2d3 and trpv5 inhibitors inhibited oc differentiation. conclusions: 1,25(oh)2d3 can inhibit trpv5 expression as well as trpv5 inhibitors during oc differentiation. this suggests that 1,25(oh)2d3 may suppress oc differentiation by inhibiting trpv5 expression.
