There are some 20 human trials in progress, mostly in China, involving the novel gene-editing technique which has the potential to revolutionize cancer treatment. But it doesn't stop there. Re- searchers are also using CRISPR in experiments aimed at creating mutant mosquitos bioengineered to resist malaria-causing parasites. Scientists are using CRISPR to in- sert the DNA of wooly mammoths into lab-grown elephants in order to bring the extinct prehistoric animals back to life. CRISPR is such a power tool that there are some people calling for caution on how scientists employ the gene-editing technique. CRISPR-Cas9, which enables scientists to edit the DNA of any species with extreme precision and efficiency, offers hope of deliver- ing an affordable way of targeting cancers with altered immune cells and treating other diseases such as leukemia and HIV/AIDS. Despite the technique's touted precision, a new study indicates cloud-connecting your pipette and notebook Page 8 validation of colorants in microchips for real-time Pcr ariadna Page 11 continued on page 2 continued on page 3 that mutations occur in the areas where DNA has been cut. A recent study in the titled Un- expected mutations after CRISPR- Cas9 editing in vivo which was published in the Nature Methods, said scientists investigated muta- tions which occurred in mice DNA that had undergone CRISPR gene editing. "The investigators were able to determine that CRISPR had suc- cessfully corrected a gene that causes blindness, but found that the genomes of two independent gene therapy recipients had sus- tained more than 1,500 single-nu- cleotide mutations and more than 100 larger deletions and insertions," the Genetic Engineering and Bio- technology News reported. "None of these DNA mutations were pre- dicted by computer algorithms that are widely used by researchers to look for off-target effects." Dr. Vinit Mahajan, a co-author of the study, remains hopeful for CRISPR. "We're still upbeat about CRISPR, we're physicians, and we know that every new therapy has some potential side effects – but we need to be aware of what they are," Mahajan was quoted in a BigThink. com article. CRISPR could alter regions of the genome which researchers are not targeting, according to Dr. J. Keith Joung of Massachusetts General Hospital, a report from StatNews. com said. At a recent American Society of Hematology workshop on genome- editing, Joung showed some 150 experts from industry and academia an example where CRISPR is sup- posed to edit the VEGFA gene on chromosome 6. VEGFA stimulates production of blood vessels, in- cluding those used by cancerous tumors. Joung said studies have shown that the CRISPR can hit genes on every one of the other 22 human chromosomes. The issue of off-target effects is important.
