Remembering David Baltimore

MIT Koch Institute

September 8, 2025

With sadness, the Koch Institute marks the passing of Professor David Baltimore. A founding faculty member and formative influence behind the MIT Center for Cancer Research, he was not only a ground-breaking researcher but also a compelling and thoughtful voice for science. 

His discovery of reverse transcriptase changed the prevailing scientific dogma, earned him a 1975 Nobel Prize, and directly enables work in life sciences and biomedical laboratories everywhere. His decades-long advocacy work impacted national policy debates on topics such as recombinant DNA research, the AIDS epidemic, and genome editing.

Culture Shock

MIT News

August 27, 2018

Let's dish about chromosomes, shall we? Researchers in the Amon Lab have uncovered evidence that cells dividing in culture or in the absence of tissue architecture have significantly higher levels of chromosome mis-segregation (a condition known as aneuploidy) than those that divide within their native environments. Their findings, published in Cell and profiled by HHMI, suggest that the hallmark aneuploidy found in more than 90% of solid human tumors may be influenced by disrupted tissue architecture, independent of gene expression and mutations, and has important implications for the widespread practice of studying cells in a dish. See this work in the KI Public Galleries.

Lead author and 2014 KI Images Award winner Kristin Knouse just won a 2018 NIH Director's Early Independence Award. Congratulations!

Set and Spike!

MIT News

August 10, 2018

A new two-step approach to treating gliomas could help clinicians set the ball by quickly identifying mutations, then drive it home by delivering mutation-targeted treatment, all during the course of tumor removal surgery. In a study published in PNAS, a team of researchers including KI research affiliate Giovanni Traverso and David H. Koch Institute Professor Robert Langer developed both a 30-minute test for IDH1/2 mutations, found in 20 to 25 percent of all gliomas, and microparticles that bypass the blood-brain barrier by implantation directly into the brain. The researchers are now developing tests for other common brain tumor mutations, and expect their approach to be applicable to tumors in other parts of the body. 

A Little "Light" Cancer Detection

Medium

August 8, 2018

She may not consider herself a "real biologist" but KI and Marble Center for Cancer Nanomedicine member Angela Belcher, recently nominated for XConomy's Innovation at the Intersection Award, is making real progress in the fight against ovarian cancer. NEO.LIFE explores how she is engineering viruses to bind to tumor cells and carbon nanotubes, with the goal of improving tumor-removal surgery cancer patient prognosis. 

Summer Backpacking with the Irvine Lab

MIT News

July 11, 2018

The Irvine Lab has summer backpacking down to a T (cell). New work, published in Nature Biotechnology, describes how this Marble Center for Cancer Nanomedicine team is using nanoparticle "backpacks" to improve efficacy and lower toxicity of adoptive T cell therapy against solid tumors. Their latest particles can carry 100-fold more drug than their predecessors and will release their cargo only when the immune cells carrying them reach the tumor and become activated. Senior author and principal investigator Darrell Irvine is a co-founder of startup company Torque, which is preparing to blaze a trail into the clinic later this year.

Slow Down, You Grow Too Fast

MIT News

July 2, 2018

Researchers in the laboratory of KI associate director and MIT Center for Precision Cancer Medicine member Matthew Vander Heiden are looking at aspartate as a limiting nutrient for cancer cells and feeling groovy. Their latest paper, published in Nature Cell Biology and further covered in Nature News & Views, explains how and why this amino acid is important for cell proliferation and argues that targeting aspartate production may reduce the growth of some tumors. 

The Unstoppable Nancy Hopkins

MIT News

June 25, 2018

KI member and MIT Professor Emerita Nancy Hopkins may be officially retired, but she is not slowing down. After co-authoing a review of the molecular mechanisms of the preventable causes of cancer in the United States for Genes & Development, she sat down with MIT News to share her perspective on the impact and potential of cancer prevention. On September 5, Hopkins will be honored with the 2018 Xconomy Lifetime Achievement Award for her contributions to genetics, cancer research, and gender equity in science.

Weight For It

MIT News

June 22, 2018

The KI's Vander Heiden Lab, in collaboration with researchers and clinicians at Dana-Farber Cancer Institute, is exploring the connections between pancreatic cancer and weight loss. As seen in Nature, the team looked at tissue wasting mechanisms in mice with early stage tumors and found that loss of pancreatic digestive enzymes can contribute to early weight loss in pancreatic cancer. They also examined blood samples and clinical data from more than 700 pancreatic cancer patients, determining that tissue loss does not necessarily correlate with lower survival rates and suggesting that detecting such tissue loss could lead to earlier diagnosis. The work was supported in part by the Koch Institute Frontier Research Program through the Kathy and Curt Marble Cancer Research Fund and the MIT Center for Precision Cancer Medicine.

Pushing BBBoundaries, Crossing BBBarriers

MIT News

June 4, 2018

Blood brain barrier getting in the way of brain cancer treatment? Na-no problem! A collaborative effort between the laboratories of Paula Hammond, a David H. Koch Professor in Engineering and head of MIT's Department of Chemical Engineering, Michael Yaffe, the David H. Koch Professor of Science and director of MIT's Center for Precision Cancer Medicine, and former Charles W. and Jennifer C. Johnson Clinical Investigator Scott Floyd has yielded a layered nanoparticle coated with a protein known as transferrin that can pass through the blood brain barrier to deliver a targeted one-two punch to glioblastoma tumor cells. Mice treated with these transferrin-coated nanoparticles survived for twice as long as mice that received other treatments. The work is described in Nature Communications and was supported in part by the Koch Institute Frontier Research Program, a KI Quinquennial Cancer Research Fellowship, and the Bridge Project.

Spreading Weinberg Wisdom

MIT Koch Institute

May 2, 2018

From shared insights to exciting new research — KI member and director of the Ludwig Center for Molecular Oncology at MIT, Robert Weinberg, has had his cancer research expertise on full display this spring. Take, for example, this characteristically frank comment on new claims linking coffee and cancer, or this overview of cancer and its prominence in modern life for The Guardian. Perhaps the most buzzworthy highlight from Weinberg this season, however, is new research on potential outcomes of breast cancer surgery. In April, he and his team published findings in Science Translational Medicine suggesting that surgery for breast cancer patients may trigger a systemic immune response that allows for early metastatic relapse during the healing process. However, the study also includes some good news, showing that taking a non-steroidal anti-inflammatory drug (NSAID) after breast cancer surgery may prevent such a relapse. This new understanding about the connections between post-surgical wound healing, inflammation, and metastasis could bring change to the standard of care for breast cancer patients. The work, also featured by STAT and WBUR, was supported in part by a TRANSCEND grant through the KI's alliance with Janssen Pharmaceuticals, Inc. Read more.
