Three Billion Base Pairs vs. One Powerful Computer

a stand of DNA

The human genome comprises roughly three billion base pairs and around 20,000 protein-coding genes, according to recent estimates. That’s a lot of information crammed into the tiny nucleus of a cell, and it doesn’t even include the many genes that do not produce a protein or the fact that most genes come in multiple flavors that vary in different individuals. Add to that the phenomenon of an identical gene being either more or less active in two different people and you can quickly end up with genomic datasets that would overload nearly any computer. Fortunately for IRP senior investigator Daniel Levy, M.D., the NIH IRP has one of the few computer systems in the world that can handle this mountain of information.

Epigenetics in Cancer Individualizes Environmental and Hereditary Risks

You may already know that diet, obesity, exposure to the sun, radiation, and hormones are just a few of the many risk factors associated with cancer diagnoses. But, do you know about other risk factors, especially those playing out through epigenetics, the molecular relationship between the environment and our DNA? Read more...

Breaking the Chains Forged in Life

In Charles Dickens’ 1843 classic, A Christmas Carol, Ebenezer Scrooge is visited by four ghosts who help him to see the error of his ways and embrace a life of service. Scrooge is then able to correct the actions that could have led to his demise. Researchers studying epigenetics take on a similar task.
