Identification of new central nervous system specific mouse microRNAs.
MicroRNAs (miRNAs) are small regulatory molecules suppressing mRNA activity in metazoans. Here we describe two new miRNAs cloned from brain tissue of mouse embryos. These miRNAs are expressed mainly during embryogenesis and specifically in the central nervous system. We also established the expression patterns of three recently identified miRNAs that were found in our short RNA library. All of them were expressed in the brain and spinal chord but while miR-410 and miR-431 were central nervous system specific, miR-500 was also expressed in limb buds. In addition, the expression of miR-500 in limb buds showed very strong asymmetry in favour of the left hand side.
