Figure 2. miR-34a inhibits proliferation of osteosarcoma in vitro.

Figure 2

Every 24 h, MTT assay was performed on three groups of SOSP-9607 cells (Blank, SOSP-9607 cells; control, stable SOSP-9607 cells transfected with pcDNA3.1; miR-34a, stable SOSP-9607 cells transfected with pcDNA-miR34a) and SAOS-2 cells (pcDNA3.1, SAOS-2 cells transiently transfected with pcDNA3.1; pcDNA-miR34a, SAOS-2 cells transiently transfected with pcDNA-miR34a) respectively (A, B). The viable cell number was evaluated as the value of the absorbance at 490 nm with a reference wavelength of 630 nm. Values of optical density (OD) are expressed as means±SD. *P<0.05, ** p<0.01 (n = 3) are considered as accepted as statistically significant.
