miR-217 is downregulated in human osteosarcoma cell lines and tissues.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
(A) Relative expression of miR-217 in four human osteosarcoma cell lines (MG-63, U2OS, SOSP-9607, and SAOS-2) and one normal bone cell line (hFOB) was determined by qRT-PCR. Quantification of miR-217 was measured by qRT-PCR with specific primers for miR-217 and snRNA U6. (B) Relative expression of miR-217 in 60 primary osteosarcoma tissues compared with their pair-matched nontumor tissues. Data areshown as log10 of relative ratio change of osteosarcoma tissues relative tonormal tissues. (C) Relative miR-217expressionlevels in osteosarcoma tissues and adjacent normal regions; (D)The expression of miR-217 in the osteosarcoma tissues from the patients with metastases was lower than that in non-metastases tissues. All data uses t test and is shown as mean ±SEM.
