THE IMPACT OF YOUR SUPPORT<br />

Hutch Holiday Gala<br />

Basic Sciences<br />

Endowment<br />

At <strong>Fred</strong> <strong>Hutchinson</strong> <strong>Cancer</strong> <strong>Research</strong> <strong>Center</strong>, our<br />

compassion drives us to seek a better future for<br />

those with cancer, HIV/AIDS and related diseases. At the<br />

heart of our research are the dedicated scientists of the<br />

Basic Sciences Division, who are continually pushing the<br />

boundaries to gain a fundamental understanding of how<br />

biology works. This exploration of life’s basic mechanisms is<br />

leading to remarkable discoveries and potentially lifesaving<br />

advances.<br />

Private support is crucial to the scientific foundations upon<br />

which new strategies to fight cancer and other diseases<br />

are built. At the 2011 Hutch Holiday Gala, attendees<br />

demonstrated their commitment to the <strong>Hutchinson</strong> <strong>Center</strong>’s<br />

mission and researchers once again, this time raising more<br />

than $6.2 million for a Basic Sciences Endowment, and<br />

bringing the lifetime Gala total to more than $81.4 million in<br />

the 36-year history of the event.<br />

In this report, we highlight two projects being led by Basic<br />

Sciences Division researchers that would not be possible<br />

without generous partners like you:<br />

• A breakthrough in understanding the evolutionary<br />

conflict between HIV-related viruses and their hosts’<br />

defense systems<br />

• A discovery into protein structure that is paving the way<br />

for corrective gene therapy that could cure multiple<br />

diseases<br />

Thank you for helping to fund projects such as these and<br />

joining the <strong>Hutchinson</strong> <strong>Center</strong> in its goal to improve the lives<br />

of those who battle cancer and related diseases.<br />

Evolutionary genetic arms race<br />

<strong>Hutchinson</strong> <strong>Center</strong> scientist Dr. Harmit Malik and his<br />

colleagues study the genetic tugs-of-war between viruses<br />

and their hosts, epic battles in which each side rapidly<br />

evolves to gain the upper hand over its opponent. A<br />

world leader in his field, Dr. Malik explores the history of<br />

these conflicts in order to improve our future chances of<br />

successfully treating deadly infections such as HIV.


THE IMPACT OF YOUR SUPPORT<br />

Recently, Dr. Malik and an interdisciplinary team of<br />

<strong>Hutchinson</strong> <strong>Center</strong> investigators traced, for the first time<br />

ever, the origin of one such evolutionary struggle. It pits two<br />

proteins against each other: a host protein that helps cells<br />

resist infection by HIV-related viruses and a protein made<br />

by some members of the HIV family that can degrade that<br />

defensive host protein. By piecing together a family tree of<br />

sorts for the viral protein, the researchers found that the<br />

most common form of the human virus, known as HIV-1, is<br />

part of a branch that never acquired the ability to counteract<br />

this host defense mechanism.<br />

If HIV-1 can’t break down the protective protein, then why,<br />

you may ask, is it so successful at infecting human cells?<br />

One possibility is that this supposed weakness in the virus<br />

has actually made it stronger, driving it to compensate by<br />

developing even more effective countermeasures. More<br />

research will need to be done before we know for sure, but<br />

already discoveries like Dr. Malik’s are giving scientists<br />

the answers they will need to design better vaccines and<br />

therapies to prevent and treat HIV infection.<br />

Paving the way for corrective therapy<br />

Dr. Barry Stoddard and colleagues have solved the threedimensional<br />

structure of a recently discovered type of<br />

gene-targeting protein called a TAL effector. These proteins<br />

have the potential to be extremely powerful tools for gene<br />

therapy and gene correction, offering the possibility of better<br />

treatments, and even cures, for disease.<br />

TAL effectors occur naturally in a type of bacteria that can<br />

infect certain plants, but, as Dr. Stoddard explains, “In<br />

biotechnology and medicine, TAL effectors can be used<br />

by scientists to seek out and bind to DNA targets in any<br />

organism of choice, including genes in humans that contain<br />

disease-causing mutations that we might want to correct.”<br />

Using sophisticated computational analyses and X-ray<br />

technology to study the arrangement of the protein’s<br />

individual atoms, the group determined that TAL effectors<br />

have a modular, LEGO-like architecture that allows them to<br />

be easily reshuffled and engineered for DNA targeting.<br />

Solving the structure of the TAL effector protein allows<br />

scientists to see exactly how the protein binds to its DNA<br />

target. With the form finally unveiled, scientists can now<br />

engineer the proteins to work more effectively in a variety of<br />

medical applications.<br />
