Chinese scientists to carry out first human gene editing tri
Researchers in China will be testing the revolutionary CRISPR-Cas9 gene editing technique in a lung cancer trial. A team led by Dr. Lu You at Sichuan University’s West China Hospital in Chengdu received approval to carry out the trial from the hospital’s review board on July 6, in a process that took just half a year. CRISPR, which stands for clustered regularly interspaced short palindromic repeats, are repeats of base sequences in DNA. Scientists at Osaka University in Japan found CRISPR sequences in bacteria in 1987. Interestingly, CRISPR sequences are invariably followed by a group of genes encoding DNA-cutting enzymes, which are termed CRISPR-associated genes, or Cas for short.
