RNA interference is a process where the breakdown of RNA molecules into miRNA inhibits gene expression of specific host mRNA sequences. miRNA is produced within the cell starting from primary miRNA (pri-miRNA) in the nucleus. These long sequences are cleaved into smaller precursor miRNA (pre-miRNA), which are usually 70 nucleotides with a hairpin structure. Pri-miRNA are identif… WebJan 23, 2024 · Objectives: DROSHA and DICER have central roles in the biogenesis of microRNAs (miRNAs). However, we previously showed that in the murine system, DROSHA has an alternate function where it directly recognises and cleaves protein-coding messenger (m)RNAs and this is critical for safeguarding the pluripotency of haematopoietic stem …
