Abstract

Abstract: Objective To investigate the expression of transient receptor potential vanilloid receptor V(TRPV5)during the differentiation of osteoclasts mediated by intermittent tensile stress. Methods Murine osteoclasts were divided into 4 groups and mediated by different loading stress: group A(1 000 με), group B(3 000 με), group C(5 000 με), and group D(0 με). The mRNA expression of TRPV5 in the 4 groups was detected with fluorescence quantitative PCR before and after the differentiation. Results Compared with group D, the other 3 groups had higher mRNA expression of TRPV5(P<0.001). Pairwise comparison results showed that there was no statistical difference between group B and C(P>0.05),there was statistical difference between any other two groups(P<0.05). Conclusion Intermittent tensile stress promotes the expression of TRPV5 channel gene in osteoclasts within a certain range.
