miR-34a specifically inhibits proliferation of proneural glioma cells.

<p><b>A</b>) aCGH analyses of cell lines used. Proneural TS543 and TS667 cells both harbor PDGFRA amplification on chromosome 4, and mesenchymal TS600 cells harbor EGFR amplification on chromosome 7. <b>B</b>) Cells were transiently transfected with miR-34a mimics or control oligonucleotides and for assayed cell numbers over 3–8 days by MTT assay.
