Accelerating Healthcare Solutions with David Lee

David Lee (1969) returned to MIT 40 years after graduation to develop low-cost, high-impact healthcare solutions. The work he has done in the 15 years since will have a tremendous impact on the treatment of patients with sepsis, transplants, and several forms of cancer. More immediately, it’s the topic of a presentation Lee will give as part of Tech Reunion 2019, to mark his 50th class reunion.  From old school skills to next generation devices, business to bedside, hear how Lee's MIT collaborations (and support from the Koch Institute Frontier Research Program) helped him begin a second career, found two businesses, and impact people’s lives for the better. He presents, “Accelerating healthcare solutions: Re-engaging in technology at MIT 40 years post-graduation,” on June 7, from 3-4:30 PM in the Koch Institute Auditorium. MIT alumni and Tech Reunion attendees welcome! more...

Better Breast Cancer Risk Prediction

A deep-learning model developed by KI member and Delta Electronics Professor Regina Barzilay can predict from a mammogram if a patient is likely to develop breast cancer within five years. Trained on mammograms and outcomes from more than 60,000 patients at Massachusetts General Hospital, the model learned to spot patterns in mammograms that are precursors to malignant tumors. Published in Radiologythe model performed significantly better than existing approaches, and could be used in the future to build personalized breast cancer screening plans. Read more.

At last month's SOLUTIONS with/in/sight, Barzilay was joined by her co-author, Harvard Medical School Professor and Director of Breast Imaging at Massachussetts General Hospital Constance Lehman, to talk about the new model and earlier work using deep-learning models to screen for dense breast tissue. Managing Director of The Boston Globe and STAT Linda Pizzuti Henry moderated the discussion, with an introduction from MIT president emerita and KI faculty member Susan Hockfield. Watch videomore...

Guiding Light

A new system developed by the laboratory of KI member and James Mason Crafts Professor Angela Belcher could pinpoint ovarian tumors during debulking surgery and improve survival rates for patients. Most ovarian cancers are diagnosed in advanced stages of the disease, after tumors—often quite small—have spread so abundantly throughout the abdomen that it is difficult for a surgeon to remove them all. In a mouse study led by Mazumdar-Shaw International Oncology Fellow Neelkanth Bardhan and published in ACS Nano, researchers identified tumors as small as 0.2 millimeters with a combination of near-infrared light and single-walled carbon nanotubule probes. Researchers are seeking approval for a FDA phase 1 clinical trial for the system and plan to adapt it for monitoring patients for recurrence of tumors and for early-stage diagnosis of ovarian cancer. The system was developed with support from the Koch Institute Frontier Research Program and later tested with support from the Bridge Project. more...

Your Summer Reading Is Here

Susan Hockfield's book, The Age of Living Machines has officially hit the bookshelves. Offering a glimpse into a possible future driven by the convergence of biology and engineering, Hockfield describes how researchers at the KI, MIT, and beyond are assembling the "biological parts list" developed from 20th-century revelations in molecular biology and genetics into a stunning array of "living machines" to solve some of the most important—and difficult—challenges of the 21st century. Get a sneak peek into this exciting new book at MIT News or on WGBH's Greater Boston. more...

 Aneuploidy in Prostate Cancer

Prostate cancers with higher levels of aneuploidy—an abnormal number of chromosomes—also come with higher lethality risk for patients, according to a new study from a Bridge Project team co-led by Angelika Amon, KI member and Kathleen and Curtis Marble Professor in Cancer Research, and Harvard T.H. Chan School of Public Health faculty member Lorelei Mucci. Using a collection of prostate cancer tumor samples, researchers extrapolated the degree of aneuploidy from each sample's genetic sequencing information and compared it to information about patient outcomes. Patients with a higher degree of aneuploidy were five times more likely to die from the disease. The findings, published in Proceedings of the National Academy of Sciencessuggest that aneuploidy could be used to more accurately predict patients' prognosis and to identify patients who might need more aggressive treatment.  more...

Alpaca Punch

In two studies appearing in Proceedings of the National Academy of Sciences, researchers from the laboratory of Richard Hynes, KI member and Daniel K. Ludwig Professor for Cancer Research, showed how tumors and metastases could be imaged and treated with lightweight antibodies (or, "nanobodies") derived from alpacas. The nanobodies target the extracellular matrix (ECM), which plays important roles in cancer cell survival, invasion, and development, and is more genetically stable, less heterogenous, and easier to access than cancer cells. 

The researchers, led by Mazumdar-Shaw International Oncology Fellow Noor Jailkhani, built a nanobody library for ECM proteins that were abundant in the tumor microenvironment, but absent from healthy tissues. In one study, researchers treated mouse cancer models with radioisotope-labled nanobodies. PET/CT imaging revealed clearly visible tumors and metastases. In the companion study, they used the same nanobodies to develop nanobody-based chimeric antigen receptor (CAR) T cells to target solid tumors.     more...

"And the Academy and awards go to..."

...Paula Hammond, Ed Boyden, and Aviv Regev, for their election to the National Academy of Sciences. Hammond, David H. Koch Professor in Engineering and head of MIT's Department of Chemical Engineering, is being honored for her work in nanomedicine, using biomaterials to enable targeted drug delivery and self-assembled materials systems for electrochemical energy devices.

Row, Row, Row Your Bot

Microrobots developed by Bhatia Lab researchers swim through the bloodstream with a payload of nanoparticles in their wake. Inspired by the flagella of bacteria, researchers equipped microbots with helical propellers and placed them in a fluidic model designed to simulate disease-like environments. When an external magnet is applied, the micropropellers rotate, generating flow disruptions that drag nanoparticles along with them. Researchers also conscripted the iron oxide-producing bacteria Magnetospirillum magneticum to generate the wake. Their findings, described in Science Advances, could help overcome the challenge of moving drug-carrying nanoparticles out of blood vessels and into tumors or other target tissues.  more...

What's On Your Plate?

Cancer cell metabolism—as well as tumor growth and drug sensitivity—is profoundly influenced by the nutrient profile of the surrounding microenvironment. However, according to new research from the laboratory of KI member Matthew Vander Heiden, the nutrient composition of tumor interstitial fluid is significantly different from the plasma that feeds normal cells. Research in mice also shows variation based on diet and tumor location and site of origin. The findings, published in eLife with former KI postdoc Alex Muir as co-senior author, suggest that model cancer cells grown in media that more closely replicate physiological nutrient levels might better predict which genes are essential to tumor metabolism. The research was funded in part by the MIT Center for Precision Cancer Medicine and the Ludwig Center for Molecular Oncologymore...
