CRISPR Revolution: Moving Towards the Science of Future

On 7th June, ESCI-UPF held an online session about genome editing tool CRISPR with Dr Carme Cortina, Research Associate at Colorectal Cancer Laboratory Group of the IRB Barcelona; Dr Ana Janic, Principal Investigator at Cell and Molecular Biology Program at DCEXS-UPF; and Dr Alberto Meseguer, Academic Coordinator at ESCI-UPF Bachelor’s Degree in Bioinformatics. Dr Arnau Cordomí, the BDBI Academic Coordinator, was the round table moderator.
CRISPR is a revolutionary genome-editing system that acts as precise molecular scissors capable of cutting the DNA in a chosen genome location. This system’s importance lies in being much cheaper and easier to design than previous genome editing tools.
During the talk, the speakers discussed the origin of the system (and the fight over its patent between Charpentier/Doudna and Feng Zhang), the nowadays application of the technique in clinical trials –related to blood diseases and cancer immunotherapy–, and the practice conducted by first-year BDBI students using CRISPR to knock-out P53 tumour suppressor gene.
Afterwards, they spoke about the concerns of using this genome-editing tool. From the biological perspective, as a secondary effect, CRISPR can generate unwanted mutations by cutting other places of the genome rather than only the desired ones. From an ethical point of view, CRISPR opens a debate on the limits of scientific purposes. One of the best examples of this concern is the Nana and Lulu case, where Dr He Jiankui used CRISPR to modify their embryo genome to make them resistant to HIV.
At the end of the session, the speakers chatted about the future of the CRISPR tool, the world of possibilities it opens, and the direction toward genome editing systems are moving.
Two weeks ago, the professor and researcher of the UNESCO Chair in Life Cycle and Climate Change Ilija Sazdovski was invited to hold a lecture at the European Parliament about the role of innovation in shaping university curricula within the sustainability domain.
