Will be anonymous’ sperm donation a thing of the past? IVF people claims for their right to know

Thanks to DNA tests and the internet but mainly to the mobilization of IVF people to defend their right to know the identity of their biological parents, many persons could find their biological parents despite the fact that the law that protects the anonymity of gamete donor is...

CRISPR-mediated therapeutic editing corrects a genetic disease in mice’s fetuses. May it pave way in humans?

Researchers at the Children’s Hospital of Philadelphia Institute (CHOP) and the University of Pennsylvania have published the first proof-of-concept demonstrating the possibility of using CRISPR gene editing to cure diseases in utero (Nature Medicine). Using this strategy, they...

“Gene-edited babies” in China. What has said the coinventor of CRISPR technique, Jennifer Doudna?

Jennifer Doudna said, “It is a matter of when and where the gene editing technology will be used in human embryos”. As we commented HERE a Chinese scientist claimed he has used the CRISPR gene-editing science to produce two infants who will be resistant to HIV...

Cocaine effects and overdose successfully treated with CRISPR gene editing in mice

Researchers at the University of Chicago have used the CRISPR gene editing tool to treat cocaine addiction in mice, and suggest that it will be feasible to use this treatment in people. Methodology. Producing an artificial enzyme  The study, published in Nature Biomedical...

Current knowledge does not justify universal genetic tests for newborns, scientists and ethicists affirms

As discussed in an article in The Lancet, Francis Collins, director of the United States National Institutes of Health – NIH, said in 2014 that “over the course of the next few decades, the availability of cheap, efficient DNA technology will lead to a medical...

DNA methylation is a sophisticated biological mechanism with objective implications in biology and medicine

An article in Lancet approaches the DNA  methylation (the incorporation of molecular “marks” on the DNA) who constitutes a marking system that holds instructions on how and when the genetic information contained in the DNA should be read. Unlike the genomic structure, which is...

The first genetically modified babies in China

A number of media outlets have reported the news: Chinese scientists produce genetically edited babies for the first time (see HERE and HERE. According to He Jiankui, the Chinese scientist responsible, his team has managed to obtain the first babies genetically modified in the...

Fathered 200 children hoping that they would one day track one of them. Now he met a daughter

Worried he’d never have a family, Louis became a prolific sperm donor, hoping that his children would one day track him down.                                    ‘Louis’ with his daughter, Joyce Curiere, who traced him after getting a DNA test Louis used to cycle to the sperm...

CRISPR-Cas9 causes more damage in the genome than thought

At present CRISPR-Cas9  produces off-target effects See video below The CRISPR-Cas9 genome editing system causes more damage in the cellular DNA than previously believed, and this is not detected by standard tests, according to a study published in Nature Biotechnology. While it...

Gene drive used in mammals for the first time. Possible effects of the genome modification of entire species

Could we change natural design without mayors consequences?  Gene drive technology allows genome of entire species to be modified, has been used for the first time in mammals (mice). The article has not yet been published, but it can already be read on the online preprint server...
