  • Fig. 3: PE3 and PE3b systems nick the non-edited strand to increase prime editing efficiency. (nature.com)
  • We also evaluate on-target efficiency prediction algorithms against available datasets. (biomedcentral.com)
  • Streptomyces-produced quinolone and coumarin antibiotics, such as novobiocin, interfere with a protein called gyrase that assists in the normal separation of double-stranded DNA during replication of DNA or transcription of messenger RNA. (icr.org)
  • RNA-catalyzed RNA replication is widely believed to have supported a primordial biology. (elifesciences.org)
  • To address this apparent paradox, we have re-examined the building blocks used for RNA replication. (elifesciences.org)
  • Triplet substrates thus resolve a central incongruity of RNA replication, and here allow the ribozyme to synthesise its own catalytic subunit '+' and '-' strands in segments and assemble them into a new active ribozyme. (elifesciences.org)
  • Several studies demonstrate important associations between differential expression of micro-RNAs (miRs) and the prognosis of CRC. (biorxiv.org)
  • According to co-author and phage expert Vivek Mutalik, a staff scientist in Berkeley Lab's Biosciences Area, these findings indicate that the CRISPR system can defend against diverse DNA-based phages by targeting their RNA after it has been converted from DNA by the bacteria's own enzymes prior to protein translation.

  • Fig. 4: Targeted insertions, deletions, and all 12 types of point mutation with PE3 at seven endogenous genomic loci in HEK293T cells. (nature.com)
  • RNA Sanger sequencing analysis was performed in AEG‑1‑deficient HT22 cells and wild‑type HT22 cells without knockout (KO). (spandidos-publications.com)
  • Targeted drug delivery to specific group of cells offers an attractive strategy to minimize the undesirable side effects and achieve the therapeutic effect with a lower dose. (biosyn.com)
  • To date, many strategies have been investigated to accomplish this goal, and some of these strategies rely on the differences between the cellular compositions of the targeted cells and those of the nontargeted cells. (biosyn.com)
  • Nonetheless, it appears that in order to cure aging we will need to target multiple types of cells and possibly address different types of molecular damage and malfunction. (senescence.info)
  • The results suggest that PRKRA functions in the nuage as an element of RNA silencing system and plays unknown role in the ectoplasmic specialization and at the tubulobulbar complexes of Sertoli cells attaching the head of late spermatids. (hindawi.com)
