Development of CRISPR detection | EDITGENE

CRISPR detection technology is a gene editing technology based on the CRISPR-Cas system for precise editing and detection in the genome.

The development of CRISPR detection technology can be divided into the following stages:

Initial discovery stage: In the 1980s, scientists discovered the CRISPR-Cas system. This discovery laid the foundation for subsequent gene editing technology.

Technology development stage: In the early 21st century, with the development of genomics and molecular biology, scientists began to study how to use the CRISPR-Cas system for gene editing. After a series of research and exploration, the CRISPR-Cas9 system was finally developed, a powerful gene editing tool that can achieve precise editing and detection in the genome.

Application stage: As the CRISPR-Cas9 system continues to be improved and optimized, its application scope is becoming more and more extensive. At present, CRISPR detection technology has been widely used in basic research, biotechnology, medicine, agriculture, and other fields.

For example, in the medical field, CRISPR technology can be used to treat genetic diseases and cancer; in the agricultural field, it can be used to cultivate crops with excellent traits such as disease resistance, insect resistance, and stress resistance.


Although CRISPR detection technology has many advantages, it also has some challenges and limitations.

First of all, the Cas nuclease in the CRISPR-Cas system is a key factor in achieving gene editing and detection, but its accuracy and specificity in cutting DNA still need to be further improved. It has been discovered that Cas nuclease may cause off-target phenomena when cutting DNA, that is, mistakenly cutting non-target sequences, which may lead to adverse reactions such as gene mutation and cytotoxicity. Therefore, the design and screening of Cas nucleases need to be continuously optimized to improve their cutting accuracy and specificity.

Secondly, CRISPR detection technology requires the guidance of guide RNA to specifically recognize the target DNA sequence. However, guiding RNA design and synthesis remains a challenge. At present, the design of guide RNA mainly relies on experience and practice, requiring a large amount of experimental verification and optimization. In addition, designing effective guide RNA may be more difficult for certain complex genomic regions.

In addition, CRISPR detection technology usually needs to be performed in cells or tissues, which may be affected by factors such as cell type, cell proliferation status, and tissue structure. In some cases, issues such as cytotoxicity and immune response may also limit the application of CRISPR technology. Therefore, these factors need to be fully considered during the application and safety assessment conducted.

In addition, although CRISPR detection technology can achieve high-precision and efficient editing and detection of target DNA sequences, its sensitivity and specificity may still be insufficient for certain gene mutations or complex diseases. Therefore, CRISPR detection technology needs to be further improved and perfected to increase its application scope and accuracy.

[Research Frontier] New Trends in Prime Editing: Point Mutated Cells for Preclinical Gene Therapy

Image
  Prime editing is an improved gene editing technology based on the CRISPR/Cas system to achieve precise fragment insertion, deletion, and arbitrary substitution of bases at the target site of the genome, with higher accuracy and lower error rate. When it came out, it attracted widespread attention from many scientific researchers, and extensive research was conducted on the treatment of hereditary diseases, gene mutation diseases, and cancers. For example, correcting the mutant genes to treat genetic diseases or editing oncogenes in cancer cell genomes to prevent them from growing and spreading. The following three articles are about the clinical treatment of Prime Editing, bringing you the latest research trends.   Prime editing helps in the treatment of β - thalassemia, and no off-target  effect was detected         β - thalassemia is a hematopoietic system disease caused by a single gene mutation in the hemoglobin (HGB) subunit beta gene (HBB), res...

Prime editing 101：what is prime editing? | EDITGENE

Image
Prime editing is an   advanced   gene editing technology proposed by David R. Liu's team in 2019. It can mediate targeted insertions, deletions, and twelve base substitutions without DSBs and donor DNA templates to achieve precise gene editing. Prime editing has developed rapidly in the past 4   years and has shown great potential in various fields.   Prime Editing  mechanism The prime editing system consists of Prime editing guide RNA (pegRNA) and nCas9. PegRNA can be divided into a guide RNA at the 5' end, a Cas9 binding region in the middle, and a PBS (Prime-binding site) at the 3' end; nCas9 is a Cas9 nickase with single-stranded cleavage activity and fused with M-MLV reverse transcriptase. The complex recognizes PAM under the g uidance of pegRNA   and binds to the target DNA strand complementary to the guide RNA. Cas9 enzyme cuts the 3rd and 4th nucleotides of the original spacer sequence upstream of PAM to generate a nick; the broken DNA single strand...
