Mount Sinai Receives More Than $10 Million in Grant Funding for Brain Tumor Research

The Department of Neurosurgery at the Icahn School of Medicine at Mount Sinai has received more than $10 million in federal funding for several projects focusing on brain tumor research. The newest grant focuses on the use of magnetic hyperthermia therapy (MHT), a powerful nanotechnology-based treatment that may enhance the effects of radiation therapy and chemotherapy on glioblastoma tumors. The lead investigator is Constantinos Hadjipanayis, MD, PhD, Director of Neurosurgical Oncology at the Mount Sinai Health System and Chair of Neurosurgery at Mount Sinai-Union Square.

“Our neurosurgeons are at the forefront of clinical care and scientific research with the goal of translating research findings into new therapies that will improve patient outcomes,” said Joshua Bederson, MD, the Leonard I. Malis, MD / Corinne and Joseph Graber Professor of Neurosurgery at the Icahn School of Medicine at Mount Sinai, and Chair of Neurosurgery for the Mount Sinai Health System.

Dr. Hadjipanayis is the lead investigator in the $3.4 million National Institutes of Health (NIH)-funded study to examine the effects of MHT when used in conjunction with chemoradiation to treat glioblastoma, a devastating brain cancer that almost always relapses because therapy-resistant cancer cells infiltrate the body at the tumor’s margin. The study is expected to last five years and will be conducted in close partnership with Robert Ivkov, PhD, MSc, and his team at Johns Hopkins University, who developed the novel magnetic nanoparticles the studies will use. The grant involves a pilot study at Johns Hopkins treating dogs that have spontaneously developed glioblastoma tumors.

“These are powerful magnetic nanoparticles that we deliver directly into glioblastoma tumors by convection-enhanced delivery,” said Dr. Hadjipanayis. “We then apply a safe, alternating external magnetic field that oscillates the nanoparticles, which generates heat that destroys the tumor. Multiple treatments can be performed since the nanoparticles persist in glioblastoma tumors. When used in conjunction with radiation and chemotherapy, we expect this treatment will lead to improved outcomes.” 

•    Glioma Dormancy, Stem Cell Niche, and Tumor Microenvironment

Hongyan Zou, MD, PhD, Professor of Neurosurgery, and Neuroscience, at the Icahn School of Medicine at Mount Sinai, has received a $3 million NIH-funded grant to study tumor cell dormancy in glioblastoma models. The project’s goal is to dissect governing factors in the tumor microenvironment that influence tumor cell behaviors and therapy resistance. The study is expected to last five years.  

“Tumor cell dormancy is a major root for glioblastoma relapse,” said Dr. Zou. “Our team of vascular biologists, bioengineers, and neuroscientists are employing a 3D vascular glioblastoma organoid model to understand governing factors in the tumor microenvironment that promote tumor stem cell dormancy, therapy resistance, and tumor re-propagating capacity.”

•    Crosstalk between EGFR and TEAD Activity Directs Migration in Human Glioblastoma

A better understanding of the mechanisms by which glioblastoma cells infiltrate deep into the brain, evading surgical resection and chemotherapy, is needed in order to prevent tumor progression. Nadejda Tsankova, MD, PhD, Associate Professor of Pathology, and Neuroscience, at the Icahn School of Medicine at Mount Sinai, is the Principal Investigator on two studies that examine the biology of migration in glioblastoma cells. The first NIH-funded study aims to define the epigenetic landscape (nongenetic influences on gene expression) and transcriptional networks that drive properties of growth and migration in human glioblastoma cells. The second study focuses on the role of one specific transcription factor, the transcriptional enhanced associate domain (TEAD) as driver of the migratory tumor cell state, and explores its relationship to epidermal growth factor receptor (EGFR) signaling, using CRISPR-knockout and pharmacological inhibition in primary patient-derived glioblastoma cells and in immunocompetent and xenograft mouse glioma models. Dr. Tsankova has received nearly $275,000 for the first study and more than $1.8 million in funding for the second, five-year study.

“We have uncovered TEAD1 as an important driver of tumor migration,” said Dr. Tsankova. “Through our studies, we aim to gain deeper mechanistic insight into the biology of tumor migration as well as to test the therapeutic efficacy of pharmacological inhibitors of TEAD1 activity in pre-clinical mouse glioma models.”

•    Molecular and cellular mechanisms of glioma invasion 

Roland H. Friedel, PhD, Associate Professor of Neuroscience, and Neurosurgery, at the Icahn School of Medicine at Mount Sinai, is the Principal Investigator of an NIH-funded project ($1.8 million for a five-year period) to study signaling pathways that promote the migratory potential of glioblastoma invasion. 

“Infiltrative growth of glioblastoma cells is a major determinant of high lethality of glioblastoma,” said Dr. Friedel. “We have been studying novel signaling pathways that drive tumor invasion. The ultimate goal is to develop novel therapies in combination with conventional chemo radiation to curb glioblastoma progression.”

Mount Sinai's vision is to produce the safest care, the highest quality, the highest satisfaction, the best access and the best value of any health system in the nation. The Health System includes approximately 7,480 primary and specialty care physicians; 11 joint-venture ambulatory surgery centers; more than 410 ambulatory practices throughout the five boroughs of New York City, Westchester, Long Island, and Florida; and 31 affiliated community health centers. The Icahn School of Medicine is one of three medical schools that have earned distinction by multiple indicators: ranked in the top 20 by U.S. News & World Report's "Best Medical Schools", aligned with a U.S. News & World Report's "Honor Roll" Hospital, No. 12 in the nation for National Institutes of Health funding, and among the top 10 most innovative research institutions as ranked by the journal Nature in its Nature Innovation Index. This reflects a special level of excellence in education, clinical practice, and research. The Mount Sinai Hospital is ranked No. 14 on U.S. News & World Report's "Honor Roll" of top U.S. hospitals; it is one of the nation's top 20 hospitals in Cardiology/Heart Surgery, Diabetes/Endocrinology, Gastroenterology/GI Surgery, Geriatrics, Gynecology, Nephrology, Neurology/Neurosurgery, and Orthopedics in the 2019-2020 "Best Hospitals" issue. Mount Sinai's Kravis Children's Hospital also is ranked nationally in five out of ten pediatric specialties by U.S. News & World Report. The New York Eye and Ear Infirmary of Mount Sinai is ranked 12th nationally for Ophthalmology, Mount Sinai St. Luke’s and Mount Sinai West are ranked 23rd nationally for Nephrology and 25th for Diabetes/Endocrinology, and Mount Sinai South Nassau is ranked 35th nationally for Urology.
