Genome editing CRISPR-Cas9 technique. Biomedical, ecological and ethical considerations

The real possibility of using this technique for genetic modification of the human germ line, which could have serious and unpredictable consequences in the individuals treated and their offspring; it could also definitively lead to the introduction of transhumanism in society....

Genetic selection of embryos: a technique that is clearly eugenic

Just 35 years ago, the world witnessed the birth of Louise Brown, the first test-tube baby. At the beginning of this month, just a few days before the anniversary of this event, a team at the University of Oxford announced at the European Society of Human Reproduction and...

Human embryo and its mother. Their dialogue extends to the genomic area

A key issue in the Masters in Bioethics taught at our Catholic University is the “biological status of the human embryo”, because demonstrating that the early human embryo (from the blastocyst phase) is a biological being of our species and not a uniform cluster of...

Do genes influence man’s liberty?

Debate is still raging in a philosophical-legal-scientific field, although it was back in 2009 that an Italian court reduced a murderer’s sentence by one year because experts identified that the person concerned had a gene called MAOA (monoamine oxidase A), which is...

New steps towards the production of human cell lines

In 2013, Mitalipov’s group published an impressive study (Cell 153; 1228-1238, 2013) in which they reported the production of human blastocysts, and how embryonic human cell lines could be derived from them, and from these, cells of various tissues. Regardless of the ethical...

Why monozygotic twins, birth with identical DNA, are different. Do epigenetic mechanisms influence gene expression?

Epigenetic mechanisms have a real influence on the expression of the genome Why monozygotic twins with identical DNA are different. Gene expression can be conditioned by epigenetic mechanisms arising from the genome’s interaction with the environment. These mechanisms influence...

The ethics of synthetic biology. The production of “new” organisms

It is a promising technology that raises new ethical and philosophical issues, but which may also open great new opportunities for improving human life The aim of synthetic biology is to produce new biological systems that can be used to improve those currently existing, or to...
