In February 2020, a US trial showed safe CRISPR gene editing on three cancer patients. [38] In October 2020, researchers Emmanuelle Charpentier and Jennifer Doudna were awarded the Nobel Prize in Chemistry for their work in this field. [39] [40] They made history as the first two women to share this award without a male contributor. [41] [5]
CRISPR/Cas9 is one technology that targets double strand breaks in the human genome, modifying genes and providing a quick way to treat genetic disorders. Gene treatment employing the CRISPR/Cas genome editing method is known as CRISPR/Cas-based gene therapy.
Developed from a natural defense mechanism found in bacteria, CRISPR-Cas9 is the most commonly used system. Gene editing with CRISPR-Cas9 involves a Cas9 nuclease and an engineered guide RNA, which come together to allow for the precise "cutting" of one or both strands of DNA at specific locations within the genome.

The researchers used tripronuclear (3PN) zygotes fertilized by two sperm and therefore non-viable, to investigate CRISPR/Cas9-mediated gene editing in human cells. The researchers found that while CRISPR/Cas9 could effectively cleave the β-globin gene ( HBB ) , the efficiency of homologous recombination directed repair of CRISPR/Cas9 was ...
The CRISPR process, a 2013 breakthrough in biology, provides a way of controlling the basic genetic processes of life. In addition, the film documentary considers several relevant questions including, How will this new gene-editing ability change our relationship with nature? and, What will this new gene-editing ability mean for human evolution ...
For the first time in history, a life has been saved by gene editing.After all conventional treatments failed to provide positive results, 1-year-old Layla and her family believed the girl would ...

The approach utilises the CRISPR-Cas9 gene editing system, coupled with libraries of single guide RNAs (sgRNAs), which are designed to target every gene in the genome. Over recent years, the genome-wide CRISPR screen has emerged as a powerful tool for performing large-scale loss-of-function screens, with low noise, high knockout efficiency and ...
