Precision Medicine will need to get out of the pharma silo that is based on symptoms


Welcome to the digital era of biology (and to this modest blog I started in early 2005).

To cure many diseases, like cancer or cystic fibrosis, we will need to target genes (mutations, for ex.), not organs! I am convinced that the future of replacement medicine (organ transplant) is genomics (the science of the human genome). In 10 years we will be replacing (modifying) genes; not organs!

After low-cost airlines (Ryanair, Easyjet ...) comes "low-cost" participatory medicine. Some of my readers have recently christened this long-lasting, clumsy attempt at e-writing of mine "THE LOW-COSTE INNOVATION BLOG". I am an
early adopter of scientific MOOCs. My name's Catherine Coste. I've earned myself four MIT digital diplomas: 7.00x, 7.28x1, 7.28.x2 and 7QBWx. Instructor of 7.00x: Eric Lander PhD.

Upcoming books: Doomsdare, a medical thriller (action taking place in Beijing) Fall 2016; Jesus CRISPR Superstar, a sci-fi -- French title: La Passion du CRISPR (2017). Special thanks to Prof. Emmanuel Lincot, lawyer David Kilgour and Isabelle Provost for their help.

I love Genomics. Would you rather donate your data, or... your vital organs?

"Engineering cells to repair the damage done by heart attacks."

"This micrograph, a winner in the Federation of American Societies for Experimental Biology’s 2013 BioArt Competition, shows cells that have been specially engineered to repair the damage done by heart attacks—which strike more than 700,000 Americans every year."

"Working with rat heart muscle cells grown in a lab dish, NIH-supported bioengineers at Harvard Medical School used transplant techniques to boost the number of tiny powerhouses, called mitochondria, within the cells. If you look closely at the image above, you’ll see the heart muscle cells are tagged in green, their nuclei in blue, and their mitochondria in red.
Why on earth would a heart need extra mitochondria? At least in rat experiments, it turns out that hearts that receive additional mitochondria after a heart attack are more effective at repairing tissue damage and regaining function. The extra mitochondria make this possible by boosting energy generation, which in turn ramps up production of proteins vital for forming blood vessels, spurring cell migration to damaged tissue, and preventing cell death.
This approach holds considerable appeal because mitochondria are relatively easy to harvest from liver cells, do not trigger immune reactions when transplanted into heart cells, and could be combined with drugs or other therapies. What’s not to love about that?" (Source)
