Association of miRNA expression with extent of predicted effect upon target mRNA expression in adult murine retina. Expression of those miRNAs with a significant effect (p < 0.1) upon target gene expression ('low' group) was significantly higher than that of those miRNAs with no predicted effects ('background' group). Microarray data from Loscher et al  was available for two strains of mouse, C57 (A) and 129 (B), and both showed a similar result.
