Original Description (Extracted from the article) ... As shown in Fig. 3A, GFP levels are reduced in RGC-5 cells only upon the co-transfection of mir-23 and mir-214. In contrast, the GFP::3b-3'UTR construct is down-regulated by mir-23, mir-214 or a combination of both in the ND7 neuroblastoma cell line.// ...

We have previously shown that the Brn-3b transcription factor is subjected to post-transcriptional gene regulation by specific microRNAs (mir-23 and mir-214) in the ND7 and SHSY-5Y neuronal cell lines (Calissano et al., 2007). As Brn-3b plays an essential role in the survival of retinal ganglion cells in the rat (Erkman et al., 1996; Gan et al., 1996; Gan et al., 1999; Erkman et al., 2000), we wanted to investigate whether mir-23 and mir-214 are expressed and target Brn-3b mRNA in a retinal ganglion cell line (RGC-5) thus potentially killing the cells expressing it. Here we show that, possibly due to its pro-survival role, Brn-3b is protected from degradation by microRNAs in RGC-5 cells in contrast to its fate in other cell types. This seems to be accomplished by i) the lack of expression of one of the two microRNAs targeting its 3'UTR and by ii) the requirement of at least two distinct microRNAs to mediate its down-regulation in retinal ganglion cells. We speculate that this mechanism could have a widespread role in the regulation of mRNAs encoding for essential proteins.
