Isabel Pérez-Castro obtained her PhD in chemistry at the University of Santiago de Compostela where she completed her thesis on the synthesis of non-natural nucleosides. She then moved to the UK where she has worked in tuberculosis drug discovery at the University of Cambridge, as well as in cancer drug research at Queen Mary, University of London and the Bart's Institute of Cancer. She is now focused on new drug discovery at Magnus Life Science, associated to the Wolfson Institute for Biomedical Research - UCL.

When we talk about nucleic acids we generally think of DNA and RNA that code for proteins, and when we talk about brain cells we tend to think of neurons and their nerve impulse transmission. However, it is not news […]

Cell signalling is the mechanism by which cells communicate with each other and with their environment. Stimuli, which are generally chemical, are transmitted via a signalling cascade to effector molecules that orchestrate the appropriate response. Signalling pathways are not isolated […]

15% of human cancers worldwide may be attributed to viruses,1 with both DNA and RNA viruses being capable of causing the disease. Epstein-Barr virus, human papilloma virus, hepatitis B virus, and human herpes virus-8 are the four DNA […]

The finding that modern humans coexisted and mated with Neanderthals 50000 years ago was a breakthrough when it was announced in 2010. As a result of interbreeding, the genomes of all modern Eurasians contain a small Neanderthal DNA load that […]

Photoreceptor degeneration is one of the most common causes of partial as well as total blindness. However, one of its “positive” -or at least, not so negative- characteristics is that, while light-sensing photoreceptor cells in the surface of the retina […]

Enantiomers are any two molecules that are mirror images of each other, in the same way that, within a same person, left and right hands are: both hands look exactly the same but indeed they are not, as they cannot […]

“In the beginning, there was simplicity”
Richard Dawkins, “The selfish gene”, chapter 2
The question of how life began on Earth is as old as the human race and has occupied the thoughts and time of scientists and philosophers for […]

Since its discovery in 2003, graphene has become one of the “materials of the future”, with applications ranging from tissue engineering to energy storage. Recently, a paper published in Oncotarget by researchers at the University of Manchester has shown its […]
