(Press-News.org) Tumor cells carry specific genetic mutations that actively drive the growth and spread of cancer. When mutations in particular genes are present, standard treatments such as chemotherapy or radiation often become significantly less effective, requiring more targeted therapeutic approaches instead. One of these genes is called KEAP1.
Mutations in the E3-ligase KEAP1 are the focus of a new research project at Julius-Maximilians-Universität of Würzburg (JMU). José Pedro Friedmann Angeli, Professor of Translational Cell Biology at the Rudolf Virchow Center – Center for Integrative and Translational Bioimaging, is responsible for the project. He has secured a proof-of-concept grant worth 150,000 euros from the European Research Council (ERC) for this project.
Attacking a metabolic weak point
“With the support of the proof-of-concept grant, we plan to develop a new therapy for the treatment of KEAP1-mutated lung cancer,” says Friedmann Angeli, describing the aim of the project. Together with his team, he is focusing on a recently identified transporter that is involved in the sulfite secretion of tumor cells where his group has identified a first of its kind inhibitor to be used to block this transporter. As a result, toxic sulfite accumulates in the tumor cells, especially in KEAP1-mutated cancer cells, thereby initiating their death.
“We believe that the grant funds will enable us to further develop our lead compound SulfExstatin-1 and convert this metabolic vulnerability into a potential targeted therapy,” says Friedmann Angeli. He hopes that this further development could then represent “a much-needed treatment option for this aggressive type of cancer with a poor prognosis.”
Proof of Concept Grant
Only scientists who have an ongoing ERC grant and now wish to exploit a research result from their project on a pre-commercial basis are eligible to apply for a Proof of Concept Grant.
The aim of a Proof of Concept project is to test the market potential of such an idea. The ERC thus funds measures for further development with a view to the application readiness, commercialization, or marketing of the idea.
Specialist in a specific form of cell death
At the end of 2023, Friedmann Angeli received a two-million-euro ERC Consolidator Grant, which was used to carry out the preliminary work. There, together with his team, he identified the transporter whose inhibition is now intended to initiate the death of cancer cells.
The award winner is a pioneer in the field of ferroptosis. This special form of cell death is triggered by the accumulation of oxidized lipids and is associated with many pathological conditions, including cancer and neurodegeneration. At the same time, inducing ferroptosis in many difficult-to-treat tumors can be an effective strategy to eliminate them.

Aiming to overcome barriers that prevent digital twins from delivering on their promise to improve manufacturing, the University of Michigan and Arizona State University are inviting industrial partners to participate in a new Center for Digital Twins in Manufacturing.
"Everyone's building digital twins, but we're trying to build the glue or connectivity that enables digital twins to work together—to be composable, ...
Colombia’s biofortified rice has untapped potential to improve nutrition. And consumers want it
2025-07-14
An effective measure to fight nutrient deficiency is to increase the nutrient content of food, particularly staples that are cheap to produce and widely consumed. Scientists do this by breeding crop varieties that are higher in iron, zinc, vitamins and other nutrients, a process called biofortification.
But many factors must align for biofortified crops to be successful. They need to grow at least as well as conventional varieties, seeds need to be produced and distributed at scale, and producers require incentives to adopt new varieties. Most importantly, consumers need to actually want to eat the new ...
Study shows pregnancy can significantly worsen risk of serious brain injury in women with arteriovenous malformations

NASHVILLE — At the Society of NeuroInterventional Surgery’s (SNIS) 22nd Annual Meeting today, researchers presented findings about how pregnancy can worsen the rupture risk for brain arteriovenous malformations, abnormal connections between arteries and veins whose rupture can result in serious brain injury or death.
During pregnancy, hormonal shifts and the increased demand ...
Mapping important infrastructure could aid emergency response after hurricanes
2025-07-14
In the fall of 2024, Hurricane Helene made landfall in the southeastern U.S., later downgrading to a tropical storm causing strong winds, flooding and major destruction throughout Appalachia. Now, researchers and public health officials in ACS’ Environmental Science & Technology Letters provide a debrief about how their mapping of key locations, including private wells, septic systems and service facilities, helped distribute disaster relief in North Carolina — a part of Appalachia hit particularly ...
Nighttime pistachio snacking may reshape gut microbiome in prediabetic adults
2025-07-14
UNIVERSITY PARK, Pa. — Prediabetes affects a third of people in the United States and most of them will develop Type 2 diabetes, yet effective dietary intervention strategies remain limited. Pistachios have shown promise in improving markers of diet quality, yet little is known about how they influence the gut microbiome — a key player in glucose regulation and inflammation.
A new study led by Kristina Petersen, associate professor of nutritional sciences at Penn State, determined that nighttime pistachio ...
Friendship promotes neural and behavioral similarity
2025-07-14
How does friendship affect the human brain and influence behavior? In a new JNeurosci paper, Jia Jin and colleagues, from Shanghai International Studies University, present their work examining how close relationships influence consumer behavior and neural activity. Through a combination of long-term behavioral experiments with 175 participants and neuroimaging data from 47 participants, the researchers shed light on how friendships promote neural and behavioral similarity.
Participants evaluated products more similarly to their friends than strangers. As friends grew closer over time, this similarity ...
Neural pathway for nicotine withdrawal symptoms
2025-07-14
Because unpleasant withdrawal symptoms fuel nicotine addiction’s high relapse rate, targeting their underlying mechanisms with treatments may promote continued abstinence from the drug. In a new JNeurosci paper, Alexis Monical and Daniel McGehee, from the University of Chicago, explored a neural pathway for nicotine withdrawal symptoms stemming from the interpeduncular nucleus (IPN) to the laterodorsal tegmentum (LDTg).
The researchers previously found that high doses of nicotine interact with the IPN to cause unpleasant effects that reduce intake of the drug in mice. Other researchers have linked the IPN to nicotine withdrawal symptoms. This nucleus inhibits ...
How your DNA reveals your true age with astonishing accuracy
2025-07-14
Researchers at the Hebrew University have developed an exceptionally accurate method for predicting chronological age from DNA, based on two short genomic regions. Using deep learning networks analyzing DNA methylation patterns at a single-molecule resolution, they achieve age predictions with a median error as low as 1.36 years in individuals under 50. The method is unaffected by smoking, BMI, and sex, and has potential applications in forensics, aging research, and personalized medicine.
A team of researchers at the Hebrew University of Jerusalem, led by Bracha Ochana and Daniel Nudelman, ...
