Figure 1 It was shown by qRT-PCR tests of miR-30c that its expression was significantly different between the normal and osteosarcoma cells (4.62±1.12 vs 1.37±0.42, P<0.01).

Abbreviation: qRT-PCR, quantitative reverse transcriptase-PCR.

Figure 2 In situ hybridization tests showed that the relative expression level of miR-30c was significantly higher in the bone tissue than in osteosarcoma tissue (3.92±0.94 vs 1.23±0.45, P<0.001, scale bar: 100 µm, magnification: ×200), which is similar to that of qRT-PCR analysis.

Figure 5 The proliferation capacity of cells was significantly lower in the experimental group than in the control group at 72, 96 and 120 hours after transfection (*P<0.05).

Figure 6 There was no significant difference between the blank control group and the control group (P>0.05, one-way ANOVA), but there were significant differences between the experimental group and other groups (P<0.01, one-way ANOVA).

Figure 7 After transfecting U2OS cells with miR-30c mimics, their migration and invasiveness were found to be significantly haltered inhibited.

Notes: (A) There are less U2OS cells in each visual field in the experimental group than the control and blank control groups. Quantitative analysis in (B) shows that the difference of U2OS cells are significant between the experimental and blank control groups (P<0.05).
