Abstract
MicroRNAs (miRNAs) are noncoding RNAs that control gene expression either by degradation of mRNAs or inhibition of protein translation. miR-148a has been reported to have the impacts on tumor progression. Here, a quantitative proteomics combined with stable isotope labeling was applied to identify the global profile of miR-148a-regulated downstream proteins. The data have been deposited to the ProteomeXchange with identifier PXD000190. A total of 2938 proteins were quantified, and 55 proteins were considered to be regulated by miR-148a. We found that not only proteins associated with cancer progression but also molecules involved in neural development were regulated by miR-148a. This study is the first to identify the function of miR-148a in neural development by using a proteomic approach. Analysis of a public clinical database also showed that the patients with neural diseases could display abnormal expression of miR-148a. Moreover, silencing of miR-148a led to the abnormal morphology and decreased expression of neuron-related markers in the developing brain of zebrafish. These results provided important insight into the regulation of neurological development elicited by miR-148a. ? 2013 American Chemical Society.
