(Press-News.org) Dr. Nikolaos Koundouros, a postdoctoral associate in the Department of Pharmacology at Weill Cornell Medicine, has been awarded a 2025 Tri-Institutional Breakout Award for Junior Investigators.
Weill Cornell Medicine, Memorial Sloan Kettering Cancer Center and The Rockefeller University present the awards to up to six exceptional investigators each year—at least one from each institution—who are recognized for their notable research achievements, impactful findings and high potential for success as independent investigators. Winners receive a $25,000 unrestricted prize.
“I certainly appreciate the honor and significance of this award and know how competitive it is,” said Dr. Koundouros, who is also a Charles H. Revson Fellow in the Sandra and Edward Meyer Cancer at Weill Cornell Medicine. “It will have a huge, positive impact on my career.”
Dr. Koundouros earned his doctorate at the Institute of Cancer Research in London, during which time he helped pioneer the use of a surgical tool called the iKnife that can detect cancer by analyzing tissue chemistry in real time. He also uses advanced tools and techniques to measure how cells break down sugars and fats. His work has fueled the creation of a potential cancer treatment that targets how cells detect nutrients.
Working in the lab of Dr. John Blenis, the Anna-Maria and Stephen Kellen Professor of Cancer Research in the Department of Pharmacology, Dr. Koundouros’ research delves into how cells detect and respond to dietary nutrients—specifically omega-6 and omega-3 fatty acids—to determine how they influence the development of breast cancer.
“The main aspect of my post-doc work that I’m most proud of is our discovery of a specific mechanism that links dietary omega-6 fat intake with a distinct breast cancer subtype,” Dr. Koundouros said. “This has future implications for better understanding how nutrition-based interventions can be implemented in a more personalized way for cancer patients.”
He was the first author of a study published in Science in March that identified a clear biological link between linoleic acid, an omega-6 fatty acid commonly found in seed oils, and the growth of triple-negative breast cancer, which is particularly difficult to treat. Along with Dr. Blenis and other colleagues, he found that linoleic acid drives tumor growth through a specific pathway involving the FABP5 protein and mTORC1 signaling, which are only active in triple-negative cancers. The findings could lead to more customized nutrition and treatment strategies, an aspect he noted has been largely missing from other research in the field.
“The biggest feature of our work is that it sheds light on how we can integrate nutrition and diet-based therapies into a cancer patient’s journey,” Dr. Koundouros said. “Our study adds a more personalized and patient-centric viewpoint.”
“I received a tremendous amount of support throughout this project, and I am especially thankful to Dr. John Blenis for his guidance and mentorship, along with all the lab members who helped get this research over the line,” he added. “I also want to acknowledge Dr. Eleni Andreopoulou and her team for their crucial input on the clinical implications of our findings.”
“Nikos’ passion, intuition and dedication to discovery science has led him to uncover how the essential fatty acid, linoleic acid, an omega-6 fatty acid, which is present at very high levels in seed oils and the western diet, promotes the growth on triple negative breast cancer (TNBC),” Dr. Blenis said. “Defining this mechanism led us to discover a novel biomarker, FABP5, as well as revealing insights into how we can therapeutically block this process in TNBC for which there are few targeted therapy options. Nikos is already investigating how omega-3 fatty acids, ‘the good fatty acids’ function, as well as the role of these lipids in aging-related metabolic diseases. His incredible talent and ability to assemble these biological puzzles will undoubtedly lead to many more important discoveries.”
In upcoming research, Dr. Koundouros plans to expand on efforts to understand how nutrition and diet affect chronic diseases such as obesity, type 2 diabetes and diseases associated with unhealthy aging. Optimally, he hopes his work will improve both quality of life and therapeutic outcomes for patients with cancer and other conditions.
Dr. Koundouros was honored with the other 2025 award winners, Dr. Veena Padmanaban of The Rockefeller University and Dr. Keunwoo Ryu of Memorial Sloan Kettering Cancer Center, on June 2 at the Tri-Institutional Breakout Prize Symposium, hosted at Rockefeller.

Low vs. High blood pressure avoidance in non-cardiac surgery: Neurocognitive outcomes unchanged
2025-06-03
A large international study has found that two different approaches to managing blood pressure in older adults undergoing non-cardiac surgery, one avoiding low blood pressure (hypotension) and the other high blood pressure (hypertension), lead to similar outcomes in terms of in-hospital delirium and cognitive changes one year after surgery.
The findings were published on June 3 in Annals of Internal Medicine.
The randomized controlled trial, a substudy of the POISE-3 trial, included 2,603 patients across 54 centres in 19 countries undergoing non-cardiac surgery. Participants were 70 years old on ...
Telehealth can improve care for cats with chronic health issues
2025-06-03
Caring for a cat with chronic health conditions can be challenging for all involved, from the process of getting to a veterinary clinic to the stress of being in a strange environment with new smells and animals.
Researchers at the University of California, Davis, worked with pet owners across the United States and Canada to determine whether video telehealth visits could help improve care and the home environment for cats with feline degenerative joint disease, commonly referred to as feline arthritis.
The findings, published in the journal Frontiers in Veterinary Science, show that video calls where pet owners can ask questions and get non-medical ...
Researchers develop innovative model to study sense of smell
2025-06-03
Using a newly devised, three-dimensional model to study the regeneration of nerve tissue in the nose, researchers at Tufts University School of Medicine and the Graduate School of Biomedical Sciences (GSBS) and colleagues have discovered that one type of stem cell thought to be dormant may play a more significant role in preserving the sense of smell than originally believed.
Unlike cells in the central nervous system, sensory neurons in the nasal cavity have a remarkable ability to regenerate throughout life despite near constant exposure to the outside ...

Bowie and Robert Dudley investigated whether birds that eat sugar-rich foods—like fruit and nectar—might regularly consume alcohol produced by natural fermentation. ...
Collaboration can unlock Australia’s energy transition without sacrificing natural capital
2025-06-03
Decarbonizing Australia’s economy and protecting the country’s most critical natural resources are both possible but will require significant collaboration between energy developers, state and local governments, landowners, and interest groups, according to new research led by Princeton and The University of Queensland.
The research, published May 29 in Nature Sustainability, demonstrates that Australia can fully decarbonize its domestic and energy export economies by 2060 while avoiding harm to important areas for biodiversity outcomes, safeguarding agricultural activities, and respecting Indigenous land rights.

A protein called PCSK9 determines how pancreatic cancer cells metastasize to different parts of the body.
Scientists at UC San Francisco have discovered how pancreatic cancer cells thrive in the lungs or liver, environments that are as distinct to cells as the ocean and desert are to animals. The spread of cancer cells to organs like these often produces the very first symptoms of pancreatic ...
Eating an array of smaller fish could be nutrient-dense solution to overfishing
2025-06-03
ITHACA, N.Y. - To satisfy the seafood needs of billions of people, offering them access to a more biodiverse array of fish creates opportunities to mix-and-match species to obtain better nutrition from smaller portions of fish.
The right combination of certain species can provide up to 60% more nutrients than if someone ate the same quantity of even a highly nutritious species, according to an analysis by Cornell University researchers.
“This research hopefully highlights the importance of biodiversity, not just because of a moral quandary that we’re causing a mass extinction on Earth, but also because biodiversity can lead to better outcomes ...
