Alterations in the relative abundance of mRNA for bone morphogenetic proteins, Bmp2 and Bmp4 in the distal femur metaphysis. Relative mRNA expression of (a) Bmp2 and (b) Bmp4 was assessed in the distal femur metaphysis following 3 months of dietary treatment. Bars represent the mean fold change ± SE. Data points that do not share the same superscript letter are statistically different from each other, p < 0.05. Abbreviations: OVX, ovariectomized; Con, control diet; DP, dried plum; PP, polyphenol; K+, potassium; VitK, vitamin K; Combo, combination of PP, K+, and VitK.
