To determine if the six formin genes were biologically relevant targets of miR-335 in neuroblastoma cells, two cell lines CHP-212 (MYCN amplified) and SK-N-AS (MYCN non-amplified) were transfected with mature miR-335 mimics and the resultant alterations in formin gene expression were analysed by real-time qPCR 48 hours post-transfection. Here, MYCN is linked to neuroblastoma.
