Co-transfection of a BAF60a sensor with miR-133 led to downregulation of luciferase expression compared with co-transfection with miR-140, an unrelated miRNA not predicted to target the 3′UTR. [score:7]

The function of miR-133 or miR-1/miR-206 was inhibited by injection of specific antagomirs into somites of HH14-15 embryos, which were analyzed after 24 h. Northern blots of pooled somites showed that antagomir-133 inhibited miR-133 expression (supplementary material Fig. S4A). [score:7]
Mouse BAF60a and BAF60b expression vectors (MRC Geneservice) and GFP plasmid were used for targeted misexpression in vivo at a ratio of 5:1.

To examine the regulation of endogenous BAF60a and BAF60b transcripts by miRNAs in a physiological context and in a different species we used mouse NIH3T3 cells, which express all BAF60 variants (supplementary material Fig. S3B), but do not express the myomiRs miR-133, miR-1 or miR-206. [score:6]
We identify the chromatin remo deling factor BAF60a as an important target for miR-133 and show that BAF60b is an important target for miR-1/206, not only in myogenic C2C12 cells (Goljanek-Whysall et al., 2012b) but also in embryonic myoblasts in developing somites. [score:5]

Expression of miR-133 is up-regulated in response to increased expression of myogenin, a myogenic transcription factor which transactivates miR-133 in the presence of exogenous IGF-1. Overexpression of miR-133 has important implications on the IGF-1R/PI3K/Akt signaling pathway due to its ability to block IGF-1R expression and sequentially decrease regulation of Akt phosphorylation, miR-1 overexpression gives rise to pronounced down-regulation of phospho-Akt supported by a generalized decrease in the IGF-1 signal transduction pathway.
