Abstract: The great potential of nucleic acids as therapeutics has been recognized for a while but has experienced a tremendous attention with the recent development of RNA vaccines. In contrast to protein-targeting strategies, nucleic acid-based approaches often have the advantage that the required target selectivity is not realized via matching a specific structure, but plainly via the primary sequence of the applied RNA or DNA construct. This sequence is then either directly processed or comprises an additional unit capable of processing a target molecule. The latter is true for a number of DNA sequences, called DNAzymes, that are capable of both binding and processing a target with a high selectivity. While the mRNA technology has the inherent strength of bringing something into the system, RNA-processing DNA catalysts such as RNA-cleaving DNAzymes have the inherent strength of taking something out of the system. Consequently, the DNAzyme technology has the potential to emerge as counterpart to the mRNA technology. However, and in line with the endeavors that were required for the success of the mRNA technology, specific improvements need to be realized to unravel the full potential of RNA-processing DNAzymes. This review provides an overview of recent findings and remaining limitations.

The C. elegans heterochronic gene lin-4 encodes small RNAs with antisense complementarity to lin-14
TL;DR: Two small lin-4 transcripts of approximately 22 and 61 nt were identified in C. elegans and found to contain sequences complementary to a repeated sequence element in the 3' untranslated region (UTR) of lin-14 mRNA, suggesting that lin- 4 regulates lin- 14 translation via an antisense RNA-RNA interaction.

A species of small antisense RNA in posttranscriptional gene silencing in plants.
TL;DR: The 25-nucleotide antisense RNA detected in transgene-induced PTGS is likely synthesized from an RNA template and may represent the specificity determinant of PTGS.

TL;DR: It is proposed that the IVS portion of the RNA has several enzyme-like properties that enable it to break and reform phosphodiester bonds and that enzymes, small nuclear RNAs and folding of the pre-rRNA into an RNP are unnecessary for these reactions.

A General Purpose RNA-Cleaving DNA Enzyme
TL;DR: An in vitro selection procedure was used to develop a DNA enzyme that can be made to cleave almost any targeted RNA substrate under simulated physiological conditions, and its activity is dependent on the presence of Mg2+ ion.

A DNA enzyme that cleaves RNA
TL;DR: Using in vitro selection techniques, a DNA enzyme is obtained that catalyzes the Pb(2+)-dependent cleavage of an RNA phosphoester in a reaction that proceeds with rapid turnover, and compares favorably to that of known RNA enzymes.
