Conservative Site-specific Recombination and Phase Variation02:53

Conservative Site-specific Recombination and Phase Variation

6.9K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Homologous Recombination

The basic reaction of homologous recombination (HR) involves two chromatids that contain DNA sequences sharing a significant stretch of identity. One of these sequences uses a strand from another as a template to synthesize DNA in an enzyme-catalyzed reaction. The final product is a novel amalgamation of the two substrates. To ensure an accurate recombination of sequences, HR is restricted to the S and G2 phases of the cell cycle. At these stages, the DNA has been replicated already and the...

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

CRISPR/Cas9 Genome Editing

2.2K
The CRISPR-Cas system serves as a bacterial defense mechanism against invading genetic elements such as viruses and plasmids, forming the foundation for its adaptation as a powerful genome-editing tool. Originally discovered in prokaryotes, this system has been repurposed to revolutionize genetic engineering across a wide range of organisms, including plants, animals, and humans. The core component, Cas9, is an endonuclease derived from Streptococcus pyogenes, capable of introducing...

Summary

RNA activation (RNAa) is a newly discovered gene regulation pathway that, like RNA interference (RNAi), uses double-stranded RNA (dsRNA) to control gene expression. This mechanism offers new therapeutic potential for gene manipulation.

Background:

  • RNA interference (RNAi) is a well-established mechanism for gene silencing.
  • Recent discoveries reveal a complementary RNA-induced gene activation (RNAa) pathway.
  • Both RNAi and RNAa utilize sequence-specific double-stranded RNA (dsRNA) molecules.

Discussion:

  • RNAa shares mechanistic similarities with RNAi, suggesting a conserved regulatory system.
  • Small activating RNAs (saRNAs) are key effectors in RNAa, demonstrated across diverse species.
  • dsRNA-induced gene activation phenomena have been observed in various organisms, including plants.

Key Insights:

  • RNAa represents a novel mechanism for actively increasing gene expression.
  • The study highlights the potential of saRNAs and related molecules for therapeutic applications.
  • Understanding RNAa provides new avenues for gene function studies and biotechnological tools.

Outlook:
