MicroRNAs (miRNAs) são pequenas moléculas de RNA com aproximadamente 22 nucleotídeos incapazes de codificar proteínas e que apresentam função na regulação pós-transcricional da expressão gênica. Vários estudos vêm demonstrando o importante papel dos miRNAs na regulação do desenvolvimento embrionário de diferentes espécies, desde o controle da expressão de RNAs mensageiros durante o desenvolvimento inicial embrionário até a determinação de linhagens celulares durante a organogênese. Esta revisão irá abordar os principais miRNAs e seu papel na biologia reprodutiva, com ênfase no desenvolvimento embrionário de mamíferos.
MicroRNAs (miRNAs) are small RNA molecules with around 22 nucleotides that are unable to encode proteins and play a key role on post-transcription regulation process. Several studies have demonstrated the relevant role of miRNAs on the regulation of embryonic development on different species, from the control of gene expression during the early embryo development to determination of cellular lineages over the organogenesis. This review will present the miRNAs and its role on reproductive biology focusing on the mammalian embryo development.
