Article Title: Vitamin C Activates Osteoblastogenesis and Inhibits Osteoclastogenesis via Wnt/β-Catenin/ATF4 Signaling Pathways

doi: 10.3390/nu11030506

Figure Lengend Snippet: Expression of both osteoblast- and osteoclast-regulated proteins in vitamin C-treated rat tibias. ( A ) Western blot image of Wnt3a, β-catenin, and ATF4 and quantitative assay of Wnt3a, β-catenin, and ATF4 protein expression in vitamin C-treated rat tibias. ( B ) Western blot image of p-AKT, p-ERK, p-p38, and p-JNK and quantitative assay of p-AKT, p-ERK, p-p38, and p-JNK protein expression in vitamin C-treated rat tibias. Expression was quantified using ImageJ software relative to that of β-actin. Values represent the mean ± standard deviation. Values with different letters were significantly different according to Duncan’s multiple range test ( P < 0.05).
