Laura and Isaac Perlmutter Cancer Center at NYU Langone and the Technion-Israel Institute of Technology Officially Launch Global Cancer Research Initiative

Published: Tuesday, Apr 26, 2016

(New York, NY and Haifa, Israel, April 21, 2016) – Drug-carrying “nanoghosts” that battle melanoma and new treatments for malignant mesothelioma will be the focus of the first joint research projects led by NYU Langone Medical Center and the Technion-Israel Institute of Technology under a groundbreaking research initiative supported by noted philanthropists and NYU Langone Trustees Laura and Isaac Perlmutter.

NYU Langone and its Perlmutter Cancer Center – which the Perlmutters named in 2014 with a separate gift of more than $50 million – and the Technion established the new partnership last year to advance global collaboration in cancer research and therapeutics. The joint program is positioned to attract additional, world-class support from institutions and individuals dedicated to eradicating cancer through focused and efficient research.

The first $3 million of the Perlmutters’ $9 million donation to the two institutions is earmarked to finance six joint research projects. Co-investigators on each project will receive a two-year, $500,000 grant—$250,000 for each site. The remaining $6 million is designated to establish a state-of-the-art research facility on the Technion campus in Israel to support these and other research projects, primarily in the emerging field of cancer metabolomics, the systematic study of the unique chemical fingerprints that cellular processes leave behind. These processes are both affected by, and can influence, a variety of human diseases, including cancer.

Examining a Novel Approach to Treat Metastatic Melanoma

In the first joint collaboration, NYU Langone and Technion researchers will test the ability of a nanotechnology based on stem cell “nanoghosts” to deliver to the brain a promising treatment for metastatic melanoma, skin cancer that has spread or metastasized, and is often incurable.

In earlier studies, researchers at the Technion took a stem cell, removed its contents, and then shaped a piece of the cell’s outer membrane into a vehicle to deliver treatments into the brain. The idea was to borrow the stem cell’s outer membrane ability to home in on cancer cells. As a fragment of the former stem cell’s membrane, the nanoghost encompasses particular mechanisms that slow it enough to traverse the barrier that filters blood flowing into the brain, and which keeps most drugs from entering.

The nanoghost’s cargo is a microRNA (miR), a stretch of genetic material that fine-tunes genetic messages by blocking the conversion of genes into proteins. First applied by NYU researchers to metastatic melanoma, miR-124a, in particular, blocks the expression of cancer-promoting genes. The joint team’s experiments will seek to determine the feasibility of encapsulating miR-124a in the nanoghost, and study how the vehicle reaches its target in mouse models of the disease.

“Our studies should provide important information on nanoghosts’ general value as drug and gene carriers to the brain, and create potential for new treatment approaches against brain tumors and metastases,” said Professor Marcelle Machluf, PhD, head of the Laboratory for Cancer Drug Delivery & Cell Based Technologies at the Technion, and inventor of the nanoghost with her colleagues there. “The difficulty of delivering agents to the brain represents a major impediment to improving outcomes in patients suffering from brain tumors. Our state-of-the-art nanovehicle promises safer, simpler and more clinically relevant treatments than existing vehicles, which are comprised of polymers or synthetic vesicles which largely lack the ability to enter the brain and to target evolving and changing pathologies.”

“It is much harder to secure funding for this type of high risk, high reward research,” said Eva Hernando-Monge, PhD, associate professor in the Department of Pathology at NYU Langone, a member of the Perlmutter Cancer Center, and leader of the NYU team that first identified miR-124 as a suppressor of the growth of brain metastases. “The Perlmutters’ generous gift gives us the ability to be bold.”

Like the stem cells they are based on, nanoghosts are invisible to the immune system, which means they could potentially be made from donated stem cells, expanded to large numbers in the lab, and not just from the patient’s own supply. In the future, this could enable the stockpiling of nanoghost treatments used off the shelf without fear of immune reactions to treatments based on “foreign” cells.

New Approach to Mesothelioma

The second joint project will investigate whether an enzyme called heparanase can be used to diagnose and treat mesothelioma, a rare cancer that develops in the mesothelium, the protective lining of the lungs and other internal organs of the body. Malignant pleural mesothelioma (MPM), the most common form of the disease, often occurs after exposure to asbestos and is resistant to most therapies.
