RT‐qPCR displayed increased miR‐15b expression and decreased USP7 and KDM6B expression in osteoporosis mice injected with miR‐15b agomir, but reduced miR‐15b expression and elevated USP7 and KDM6B expression in osteoporosis mice injected with miR‐15b antagomir and expression vectors containing KDM6B (Figure 6A). Here, KDM6B is linked to osteoporosis.
