Figure Lengend Snippet: GAS inhibits the expression of osteogenesis-specific markers induced by OM. (A) RT-qPCR results show that GAS can significantly inhibit the expression of specific markers of osteogenesis in OM-induced VICs (OMI, OM-induced VICs group; GAS 50 μM treatment group; GAS 100 μM treatment group; AGP 10 μM treatment group) (n = 3). (B) Western blot results show that GAS can significantly inhibit the expression of specific markers of osteogenesis in OM-induced VICs (n = 3); (C) Semi-quantitative statistics of the band thickness of the Western blot results in B; (D) In-cell Western blot results show GAS can significantly inhibit the expression of osteogenic specific markers in OM-induced VICs (n = 3); (E) Semi-quantitative statistics of the intensity of In-cell blotting results in (D) Statistical significance is indicated by # for OMI group vs control group and * for GAS or AGP group vs OMI group ( p ≤ 0.05).

Figure Lengend Snippet: Gene expression profiles of mRNA sequencing with gastrodin (GAS) treatment under the condition of osteogenic medium induction (OMI). (A,B) Volcano map of differentially expressed genes (DEGs) in OMI versus control (OMI/Con), upregulation: 823 and downregulation: 484; in GAS versus OMI (GAS/OMI), upregulation: 247 and downregulation: 305, |log2 (fold change) (FC)| > 1 and false discovery rate (FDR) < 0.001 was considered as DEGs; (C) Venn interaction of DEGs of OMI/Con and GAS/OMI; (D) GO enrichment of the common DEGs including biological process, cellular component and molecular function; (E) KEGG pathway enrichment; a lower Q value indicates a higher degree of enrichment.
