Ethics board given green signal to monkey human gene experiment

An monkey human gene experiment conducted by Chinese and US scientists on improving monkeys’ cognitive function has been found to follow international animal rights standards, according to the Chinese research institute.

Ethics board given green signal to monkey human gene experiment

The study implanted 11 rhesus macaque monkeys with copies of the human MCPH1 gene, which scientists believe is crucial for humans’ brain development and evolution.

The project of monkey human gene experiment is led by researchers from the Kunming Institute of Zoology of the Chinese Academy of Sciences, who are working with researchers from the University of North Carolina.

The monkeys implanted with human genes developed better short-term memory and faster reaction times compared with the control group, according findings published March 27 in the China-based journal National Science Review.

The study also found that transgenic monkeys’ brains took longer to develop, in a similar fashion to humans.

The experiment of monkey human gene experiment has divided the scientific community however, with a number of Western scientists criticizing it as unethical, while some went as far to suggest, perhaps ironically, that it could lead to a Planet of the Apes-type scenario.

The Kunming Institute of Zoology told China Daily in a statement that the experiment was ethically approved in 2010.

In 2015 the animal rights committee of Kunming Biomed International, a research organization specializing in nonhuman primates, also declared the animals were being treated humanely in every step of the experiment, in accordance with domestic and international regulations, the statement said.

In 2017 the institute’s bioethics review committee again evaluated and approved the experiment before applying for National Natural Science Foundation of China funds, with the project gaining the foundation’s support.

“Experimenting on nonhuman primate models to research the brain’s cognitive function, development and related diseases have great scientific and medical values,” the statement said.

“For research purposes, there are precedents of scientists implanting human genes into lab animals such as mice, rats, and macaque monkeys, and these researchers have made great contributions to understanding life, disease mechanisms and clinical drug development.”

In 2008 US scientists implanted macaque monkeys with Huntington’s disease to further understand the condition and possibly identify a new form of treatment, with the project’s findings published in the journal Nature.

In 2009 Japanese scientists created the world’s first transgenic primates and bred monkeys with a gene that made the animals’ skin glow a fluorescent green.

Scientists said the research, also published in Nature, could open up new prospects for medical research.
