(Press-News.org) Therapies that target the utilization of fat by tumors and activate a type of cell death dependent on fat molecules may be a promising avenue to treat cancer, according to new research by UTHealth Houston.
The findings were published today in Trends in Cancer and were co-led by Daniel E. Frigo, PhD, professor at The University of Texas MD Anderson Cancer Center and a faculty member at The University of Texas MD Anderson Cancer Center UTHealth Houston Graduate School of Biomedical Sciences.
Researchers came to the conclusion through a review of 121 outside studies that examined the relationship between lipid metabolism and progression of various types of carcinoma, a cancer that starts in the tissue lining of the skin.
“Lipids can make cancers more aggressive,” said co-principal investigator Mikhail Kolonin, PhD, director of the Center for Metabolic and Degenerative Diseases in The Brown Foundation Institute of Molecular Medicine for the Prevention of Human Diseases at McGovern Medical School at UTHealth Houston. “However, there is a lipid-dependent mechanism that can be activated to fight cancer.”
Lipids are the various types of fat molecules integral to a person’s health. As cancer cells and fat tissue, which temporarily store lipids, communicate with each other, tumors can use lipids to grow or spread. But while body fat can support cancer progression, it can also cause a type of cell death known as ferroptosis.
Ferroptosis occurs when lipid peroxides build up on cell membranes. Lipid peroxides are made through the body’s normal activities, but when too many accumulate, they can become toxic.
Common cancer treatments like chemotherapy and radiation kill cancer cells by forcing the cells to undergo a different type of cell death. However, certain types of cancers can become resistant to common treatments.
Understanding the interaction between lipids and tumors can pave the way for cancer therapies that target ferroptosis-inducing chemicals and suppress a tumor’s utilization of lipids, Kolonin said.
“The implication is that there are certain therapeutic approaches that could be potentially developed to target specific mechanisms responsible for lipid processing by the tumors,” said Kolonin, who is also the Harry E. Bovay, Jr. Distinguished University Chair in Metabolic Disease Research at McGovern Medical School.
Kolonin said the review also highlights the importance of work at the Center for Metabolic and Degenerative Diseases that seeks to determine the role of cell aging on cancer progression and cachexia, or unintentional weight loss that is induced by some types of tumors.
Additional authors with UTHealth Houston include Hong Anh Cao and Joseph Rupert, PhD. Kolonin is a faculty member at MD Anderson Cancer Center UTHealth Houston Graduate School of Biomedical Sciences.
The study was in part supported by the Bovay Foundation and the Levy-Longenbaugh Fund.

CHEST releases guideline on biologic management in severe asthma
2026-01-13
Glenview, Illinois –The American College of Chest Physicians® (CHEST) recently released a new clinical guideline on biologic management in severe asthma. Published in the journal CHEST®, the guideline contains seven evidence-based recommendations to provide a framework for pulmonologists, allergists, and immunologists to implement in their own practice.
Severe asthma affects 5% to 10% of patients with asthma, which is defined as patients who require high-dose ...
Scientists create a system for tracking underwater blackouts
2026-01-13
(Santa Barbara, Calif.) — Clouds, smoke and fog may darken the skies, but sediment, algae blooms and organic matter can turn day into night on the seafloor. That’s why an international team of scientists have created the first framework to identify and compare these marine blackouts. The study, published in Communications Earth & Environment, introduces the concept of a marine darkwave: a short-term but intense episode of underwater darkness that can severely impact kelp forests, seagrass beds and other light-dependent ...
Fruit fly pigmentation guides discovery of genes that control brain dopamine and sleep
2026-01-13
Dopamine in the brain influences movement, learning, motivation and sleep. In humans, problems with dopamine are linked to conditions like Parkinson’s disease, depression and sleep disorders. While scientists know a great deal about how dopamine works in the brain, they know less about how the body controls dopamine levels. Understanding this could help treat diseases where dopamine is disrupted.
In a new study published in iScience, researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Institute at Texas Children’s Hospital (Duncan NRI) worked with the laboratory fruit fly to find new genes involved in regulating dopamine ...

New mega-analysis reveals why memory declines with age
2026-01-13
A landmark international study that pooled brain scans and memory tests from thousands of adults has shed new light on how structural brain changes are tied to memory decline as people age.
The findings — based on more than 10,000 MRI scans and over 13,000 memory assessments from 3,700 cognitively healthy adults across 13 studies — show that the connection between shrinking brain tissue and declining memory is nonlinear, stronger in older adults, and not solely driven by known Alzheimer’s-associated genes like ...
Understanding ammonia energy’s tradeoffs around the world
2026-01-13
Many people are optimistic about ammonia’s potential as an energy source and carrier of hydrogen, and though large-scale adoption would require major changes to the way it is currently manufactured, ammonia does have a number of advantages. For one thing, ammonia is energy-dense and carbon-free. It is also already produced at scale and shipped around the world, primarily for use in fertilizer.
Though current manufacturing processes give ammonia an enormous carbon footprint, cleaner ways to make ammonia do exist. A better understanding of how to guide the ammonia fuel industry’s continued development ...
UTHealth Houston researchers map gene disruptions in sporadic early onset Alzheimer’s disease across key brain regions
2026-01-13
A new study led by researchers at UTHealth Houston investigated both gene expression and regulation at single cell levels to reveal disruptions in gene function in three brain regions of patients with sporadic early onset Alzheimer’s disease.
The findings were published in Science Advances.
Only about 5% to 10% of patients with Alzheimer’s disease are younger than 65. Of those patients, 10% have mutations in the APP, PSEN1, and PSEN2 genes, which are associated with Alzheimer’s disease. The other 90% of these cases are classified as sporadic early onset Alzheimer’s, a rare and aggressive form of the ...
Minimum wage increases are linked to safer pregnancies
2026-01-13
Increases to the minimum wage may do more than bolster household income, reduce inequality and enhance worker well-being: They may also help make pregnancies safer, according to new research from Rutgers University.
A study published online ahead of the Fe in the American Journal of Preventive Medicine finds that state-level increases in the minimum wage are associated with lower rates of hypertensive disorders of pregnancy, a leading cause of maternal mortality in the United States.
The study, led by Slawa Rokicki, an assistant professor at the Rutgers School of Public Health, ...
Left in the cold: Study finds most renters shut out of energy-saving upgrades
2026-01-13
As winter heating costs rise, new research from Binghamton University, State University of New York reveals a cold truth. Renters – who make up approximately ⅓ of the U.S. population – are missing out on energy efficiency improvements that could lower their bills, make their apartments more comfortable and improve their health.
This study, “Still muddling through: Local sustainability leaders and energy efficiency in rental units,” was published in Energy Research & Social Science. ...
