Paul Marks Prize medal

Memorial Sloan Kettering has named three winners of this year’s Paul Marks Prize for Cancer Research, an award that recognizes promising young investigators. The prize, given every other year to cancer investigators who are 45 or younger, recognizes contributions to the greater understanding of cancer.

  • The award honors former MSK President and CEO Paul Marks, who led the institution for 19 years.
  • This year’s winners are Bradley Bernstein, Howard Chang, and Daniel Durocher.
  • The winners will present their research at a symposium on December 3.
  • Since it was first presented in 2001, the biennial prize has recognized 25 young scientists.

Memorial Sloan Kettering has named three investigators as recipients of this year’s Paul Marks Prize for Cancer Research. The award recognizes promising investigators aged 45 or younger for their efforts in advancing cancer research.

The winners are Bradley Bernstein, 45, of Massachusetts General Hospital; Howard Chang, 43, of Stanford University; and Daniel Durocher, 44, of the Lunenfeld-Tanenbaum Research Institute. Each will receive an award of $50,000 and speak about his research at a scientific symposium on December 3.

The award was created to honor Paul Marks, President Emeritus of MSK, for his contributions as a scientist, teacher, and leader during the 19 years he led the organization.

“The Marks Prize was established to recognize the young scientists whose work is improving the understanding of cancer across many different fields in biological research,” says Craig B. Thompson, MSK President and CEO. “Because mentoring young talent was so important to Dr. Marks, the MSK Board felt this prize would be a fitting tribute to him.”

Since it was first presented in 2001, the biennial prize has recognized 25 young scientists and has awarded more than $1 million.

Bradley E. Bernstein

Dr. Bernstein is a professor of pathology at Massachusetts General Hospital and Harvard Medical School and an Institute Member of the Broad Institute of MIT and Harvard. He earned his MD degree and a PhD in biochemistry from the University of Washington School of Medicine.

Dr. Bernstein’s research is focused on epigenetics — changes in genes that are passed down from one generation of cells to another but are not encoded in the DNA sequence. Specifically, his lab studies how the protein scaffold called chromatin packages long strands of DNA in the nucleus of each cell, and how this packaging influences both normal development and cancer.

“Over the years my lab has developed ways to map and to modify the regulatory state of our DNA. For example, we’ve identified and modulated epigenetic switches that turn our genes ‘on’ or ‘off’ in different cell types,” Dr. Bernstein explains. “We’ve used these tools to identify epigenetic defects in cancer cells, and to understand how these defects contribute to the initiation and progression of tumors.”

His discoveries have implications for understanding many types of cancer — brain tumors and leukemia in particular. “Cancers tend to be very heterogeneous, meaning that the individual cells in a patient’s tumor can vary greatly in terms of their epigenetics,” he says. “Epigenetic variability between cancer cells is critical to tumor progression, and helps explain why some cells resist therapy, causing relapse.”

One of Dr. Bernstein’s goals is to translate the laboratory tools he’s developed into diagnostics that characterize a patient’s tumor at the molecular level. “The idea is to ensure that patients receive a drug regimen that eliminates all of the different types of cells in their tumor,” he says. He is also enthusiastic about emerging therapies that directly target the epigenetic machinery, and “is especially honored to receive this award given the pioneering work of Paul Marks in this area.”

Howard Y. Chang

Dr. Chang is a professor of dermatology at Stanford University and a faculty member of its cancer biology PhD and epithelial biology programs. He is also director of the Center for Personal Dynamic Regulomes at Stanford.

His lab studies how cells know where they’re located in the body. “It turns out that there’s a whole coordinate system, kind of like a GPS, that tells cells where they are,” he says. “Genetic changes that occur in cancer can make a cell think it belongs somewhere else, commandeering the system that allows tumor cells to spread. This process is called metastasis, and it’s one of the worst things that happens in cancer because it makes the disease very hard to treat.”

In his recent work, Dr. Chang discovered that genetic material called long noncoding RNAs (also called lncRNAs, pronounced “link” RNAs) helps cells sense where they are. These lncRNAs are part of what is sometimes called the “dark matter” of the genome — the 98 percent of genetic material that does not encode for proteins.

One of the first lncRNAs he discovered is called HOTAIR, which he found could be used to predict whether breast cancer will spread. “If a woman’s breast cancer has high levels of HOTAIR, she is two to three times more likely to die of the disease,” he says. “This lncRNA is actually causing metastasis in breast cancer and other types as well. It also showed a lncRNA can be used as a prognostic.” Many lncRNAs are now known to be intimately involved in many types of cancer, and the FDA has approved diagnostic tests to measure lncRNAs for certain forms of the disease.

Dr. Chang is also a practicing dermatologist. “Wanting to understand skin is what got me interested in this field of study,” he says. “I wanted to know how skin cells know where they are, so that skin on your scalp grows hair while skin on your palms does not.”

He earned his PhD degree in biology from the Massachusetts Institute of Technology and his MD degree from Harvard Medical School.

Daniel Durocher

Dr. Durocher is Assistant Director of the Lunenfeld-Tanenbaum Research Institute, part of Sinai Health System, in Toronto and a professor of molecular genetics at the University of Toronto.

He is being recognized for his research on how cells maintain the integrity of their genomes, and especially how they deal with a particular type of damage called the DNA double-strand break. “Double-strand breaks endanger the stability of our genome and can lead to chromosome rearrangements and mutations that cause cancer,” he explains.

DNA double-strand breaks can be caused by phenomena like ionizing radiation and exposure to certain chemicals, but they can also occur when cells undergo regular division. Dr. Durocher’s work is focused on two different aspects of this biological problem. “One question is how cells repair double-strand breaks,” he says. “The other is how cells respond when a break is detected. It turns out they send out a signal to coordinate the repair.”

Much of his recent research has focused on how the BRCA1 protein helps cells respond to DNA damage. (Mutations in the BRCA1 gene, and another gene called BRCA2, are linked to cancer of the breasts and ovaries, among others.) BRCA1 is a tumor suppressor, which means its function is to prevent tumors from forming.

“We’re trying to understand how this damage response is controlled,” Dr. Durocher explains. “For example, women with BRCA1 mutations with ovarian cancer respond very well at first to chemotherapy with platinum-based drugs, but then they develop resistance. Resistance can develop because cells reorganize how they deal with double-strand breaks. We hope that by understanding this control mechanism, we’ll be able to develop ways to intervene in the future.”

His lab is also looking at ways to apply laboratory techniques such as RNA interference and genome editing to better understand the response to DNA breaks. “It’s a technology-based expansion of our program and allows us to attack these questions with a lot more precision,” he notes.

He earned his PhD degree in experimental medicine at McGill University in Montreal.
