MicroRNAs: Synthesis, Gene Regulation and Osteoblast Differentiation

The central dogma of transfer of genetic information from DNA to protein via mRNA is now challenged by small fragment of non coding RNAs typically 19-25 nucleotides in length namely microRNAs (miRNAs). miRNAs regulate expression of the protein coding genes by interfering in their mRNAs and, thus, act as key regulators of diverge cellular activities. Osteoblast differentiation, a key step in skeletal development involves activation of several...
