Gene Editing Could Help Tackle Cancer And Inherited Diseases

Gene editing techniques developed in the last five years could help in the battle against cancer and inherited diseases, a University of Exeter scientist says.

"There is always a risk with this kind of technology and fears about designer babies and we have started having discussions about that so we can understand the consequences and long-term risks," said Dr Westra, of the Environment and Sustainability Institute on the University of Exeter's Penryn Campus in Cornwall. "I think in the coming decades gene editing will become super important, and I think we will see it being used to cure some inherited diseases, to cure cancers, to restore sight to people by transplanting genes. I think it will definitely have massive importance."

On Tuesday, two highly influential academic bodies in the US shook up the scientific world with a report that, for the first time, acknowledged the medical potential of editing inherited genes. The National Academy of Sciences and National Academy of Medicine ruled that gene editing of the human "germline"—eggs, sperm and embryos—should not be seen as a red line in medical research.

Transforming our lives with laboratory-grown organs

With people living longer than ever, being able to replace bits of the human body as they wear out has become a new frontier in medicine.

Most babies born in 1900 died before the age of 50; 100 years later life expectancy in the UK now exceeds 80 years, with the number of over-65s expected to double by 2030. This trend is radically changing the age demographics of the population and creating a new set of challenges for engineers. One of the most significant of these is to give people a higher quality of life in their old age.

Significant progress has been made; 300,000 hip replacements are now performed annually worldwide, releasing people from pain, and extending the active period of their lives by 20 years or more. The success of these implants has led scientists to develop a new type of biomaterial that is promising to do for medicine what silicon did for computing.

Historically the function of biomaterials has been to replace diseased or damaged tissues. These biomaterials were selected to be as inert as possible while fulfilling mechanical roles such as teeth filling and hip replacement.
