Two children have been cancer-free for up to 18 months after receiving a controversial gene-editing therapy

A new cancer treatment helped two children with leukemia be disease-free for up to 18 months, new research reveals. Researchers from Great Ormond Street Hospital in London investigated a new cancer treatment in two infants with an aggressive form of leukemia. The youngsters received an immune-boosting treatment alongside a gene-editing technique, known as TALENS, that altered their DNA. TALENS is a form of gene editing that causes specific immune cells, known as T cells, to express proteins that target tumors. The youngsters had previously been treated with chemotherapy and received stem cell transplants.The researchers made four DNA alterations on immune cells from donors and infused the cells into the patients. Results revealed that both youngsters have been cancer-free for 16 and 18 months, respectively.
The findings were published in the journal Science Transnational Medicine.

  1. I have never heard of TALENS, only have been hearing about CRISPR recently. But, it is cool to see another type of gene editing technology help patients with a deadly disease such as leukemia. I wonder if maybe gene editing technology could be the next competition between medical technology companies.
