  • Titill er á ensku Identification of miRNAs in a liver of a human fetus by a modified method
  • Október 2009
  • Útdráttur er á ensku

    BACKGROUND: miRNAs are 17-25 nucleotides long RNA molecules that have been found to regulate gene expression in human cells. There are studies showing that different groups of miRNAs are involved in development of different tissues. In hepatocytes there are reported particular types of miRNAs that regulate gene expression.
    METHODS: We established a human fetal liver cDNA library by a modified cloning protocol. Then plasmid isolation from the colonies was performed. After sequencing and database searching, the miRNAs were recognized. RT-PCR and sequencing were carried out to validate the miRNAs detected. Real-time PCR was used to analyze the expression of each miRNA.
    RESULTS: One novel miRNA was discovered, together with another 35 previously-known miRNAs in the fetal liver. Some of them existed in variants. The miRNAs identified were validated by RT-PCR and sequencing. Quantitative analysis showed that they have variable expression.
    CONCLUSION: Our results indicate that a special group of miRNAs may play an important role in fetal liver development in a synergistic manner.
