YANG Xiao-li~1, LI Bin~1, LI Da-jin~1, et al. Effect of Gengnianchun Decoction on Bone Metabolism-Related Genes Expression in bone marrow microenvironment[J]. Chinese journal of experimental traditional medical formulae, 2009, 15(2): 26-29. DOI: 10.13422/j.cnki.syfjx.2009.02.011.
Objiective:To observe the effect of Gengnianchun Decoction(GNC) on the mRNA expression of osteoprotegerin(OPG)
osteoclast differentiation factor(RANKL) and macrophage colony stimulating factor(M-CSF) in bone marrow microenvironment of ovariectomized rats
and investigate the possible pathway of GNC in preventing and treating postmenopausal osteoporosis.Methods:Forty-two healthy adult SD rats were randomly divided into sham operation group(S group)
saline group(N group)
Different concentrations of GNC groups: high
moderate and low level groups(H
M
and L group)and nilestriol group(E group).All rats were ovariectomized except those in the sham operation group.After feding with medicines for three days
the total RNA was extracted from the lumbar vertebra to examine mRNA expression of RANKL
OPG and M-CSF by real-time PCR.Results:H group up-regulated the expression of OPG of the ovarietomized rat
whereas down-regulated the expression of M-CSF and decreased RANKL∶OPG ratio.Conclusion:The effect of GNC in treating postmenopausal osteoporosis is closely correlated with the regulation of OPG and M-CSF expressions and RANKL/OPG.
