World CRISPR Day – October 20, 2025

We celebrate World CRISPR Day on October 20 every year. It is a day to discuss the technological implications and practical application of the technology that is revolutionizing the treatment of genetic conditions. CRISPR, short for Clustered Regularly Interspaced Short Palindromic Repeat, is a technology that edits genes by finding specific bits of DNA inside a cell. Once the DNA is identified, it proceeds to alter a piece of it or to turn genes on or off. The holiday started in 2020 when the leaders in genome engineering were brought under one virtual roof.

History of World CRISPR Day

George Church, Jennifer Doudna, Emmanuelle Charpentier, and Feng Zhang, harnessed the power of CRISPR-Cas9 to alter the targeted regions of genomes, a technology that has the potential to revolutionize gene editing and was dubbed the greatest scientific breakthrough of the year 2015. For their work, Jennifer Doudna and Emmanuelle Charpentier were awarded the Nobel Prize for the year 2020, but CRISPR dates back a few years.

Dr. Yoshizumi and his team of Japanese scientists first identified CRISPRs in E. coli in 1987. They accidentally cloned a weird series of repeated sequences scattered among spacer sequences while analyzing a gene, but the monumental functions of this DNA sequence data remained unknown due to a lack of data. In 1993, researchers led by J.D. Van Embden in the Netherlands were able to shed some more light on the data. Further breakthroughs came in 2000 when a team discovered the adaptive immunity of CRISPRs. CRISPR-Cas systems can function as a defense unit to stop repeated infections by the same virus.

Further research continued, and CRISPR became a hot topic in the scientific world. The application is very broad and could change the way we see microbiology. Countries such as China have even attempted to produce results in human tests, but these attempts faced backlash from the international scientific community for ethical reasons. CRISPR is still in a premature stage and is not yet ready for full-scale human trials. Technology can benefit the future generation in ways we cannot yet predict.

World CRISPR Day FAQs

Why is CRISPR important?

CRISPR can provide scientists with tools to rewrite the genetic code of almost any organism. It is simple, cheap, and efficient compared to gene-editing techniques that were available before it.

Is CRISPR legal?

CRISPR is legal in the U.S. Many hospitals and biotech companies are currently pursuing clinical trials regulated by the FDA.

Which diseases are suitable targets for genome editing?

These include viral infections, cardiovascular diseases, metabolic disorders, defects of the immune system, hemophilia, muscular dystrophy among others.
