Date of issue: 
MicroRNA (miRNA) is a group of small, 2123-nucleotide-long, non-encoding RNA particles, which in the mature form regulate gene expression at the post-transcription level. Presently, over 3000 miRNAs are known, described in vertebrates and insects, but also in plants, fungi, unicellular organism and viruses. In the human genome, so far over 470 miRNAs have been discovered, although it is assumed that there are about 1000. Assumed that they play a role in many processes, such as differentiation of stem cells of the hematopoetic system, embryogenesis, apoptosis, regulation of the xenobiotics' metabolism, immunity, inflammations, viral and bacterial infections, as well as neurological diseases.
