Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

CRISPR/Cas9 Genome Editing

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...

Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

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.

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...

Area of Science:

  • Biotechnology
  • Genetics
  • Medical Research

Background:

  • Gene or genome editing technologies present novel therapeutic possibilities for genetic diseases.
  • Cystic fibrosis (CF) is a genetic disorder caused by mutations in the CFTR gene.
  • Previous research demonstrated CRISPR/Cas9's potential to correct CFTR mutations in intestinal organoids.

Purpose of the Study:

  • To explore the potential of gene editing for treating cystic fibrosis.
  • To identify the key challenges and future directions for applying gene editing in CF therapy.

Main Methods:

  • Utilized CRISPR/Cas9 gene editing technology.
  • Employed intestinal organoid cultures with the common F508del CFTR mutation.
  • Investigated strategies applicable to the genetic heterogeneity of CF.

Main Results:

  • CRISPR/Cas9 successfully converted CFTR-deficient cells to functional cells in organoid models.
  • Highlighted the significant challenge posed by the genetic heterogeneity of CF, with approximately 2000 known CFTR mutations.
  • Identified efficiency, accuracy, and delivery as critical hurdles for clinical translation.

Conclusions:

  • Gene editing, particularly CRISPR/Cas9, shows significant promise as a therapeutic strategy for cystic fibrosis.
  • Overcoming challenges related to genetic diversity, editing efficiency, accuracy, and targeted delivery is crucial for successful clinical application.
