| Objective: Susceptibility to diabetes-induced bone complication has been linked to Wnt signaling,
which plays an important role in bone development and remodeling. In this study, the effect of swim
training on Wnt pathway in T2DM was investigated.
Materials and methods: Forty male rats were assigned to groups: control (C), diabetic (D), exercised
control (E) and diabetic exercised (DE). One week after the induction of diabetes, animals were subjected
to swim. At the end of training, bone gene and protein levels of SOST, RUNX2 and RANKL/OPG
ratio were measured.
Results: Diabetes could significantly increase bone sclerostin expression levels, while decreased
RUNX2 mRNA and protein. Bone RANKL/OPG ratio was significantly lower in diabetic rats compared to
control group. Swim training significantly increased this ratio in DE compared to D group.
Conclusion: Swim training could partially compensate the diabetes-associated changes of Wnt
pathway possibly by moderating sclerostin or blood sugar. |
