Terasaki Institute researchers reveal vagus nerve modulation as key to combating cancer-associated cachexia featured in cell

2025-08-14
(Press-News.org) Los Angeles, CA – August 14, 2025 – The Terasaki Institute for Biomedical Innovation announces a significant advancement in addressing the fight against cancer-associated cachexia (CAC), a life-threatening syndrome responsible for over one-third of cancer-related deaths. Published in Cell, the study led by Dr. Aliesha O’Raw, Principal Investigator at the Institute, demonstrates that modulating the vagus nerve can effectively halt the progression of cachexia, enhance chemotherapy outcomes, and improve survival in preclinical models.

The study, titled “Vagal Blockade of the Brain-Liver Axis Deters Cancer-Associated Cachexia,” uncovers how cancer-induced systemic inflammation disrupts vagal tone, impairing communication along the brain-liver axis. This dysregulation leads to the depletion of HNF4α, a crucial transcription factor governing liver protein metabolism. The resulting hepatic dysfunction amplifies systemic inflammation, driving the cachectic symptoms that afflict many cancer patients.

By targeting the right cervical vagus nerve through surgical, chemical, electrical, or non-invasive transcutaneous stimulation methods, the research team successfully restored vagal function. This intervention reestablished normal liver metabolism, reduced systemic inflammation, and alleviated cachexia's clinical manifestations. Importantly, combining vagus nerve modulation with chemotherapy yielded synergistic effects, significantly improving health and survival outcomes in mouse models.

“This research addresses a critical unmet need in oncology,” said Dr. Ali Khademhosseini, Director and CEO of the Terasaki Institute for Biomedical Innovation. “Cachexia has long been a devastating complication for cancer patients. Dr. O’Raw’s work not only uncovers the biological mechanisms at play but also presents a tangible intervention strategy with real potential to transform patient care.”

Dr. Aliesha O’Raw, Principal Investigator of the study, added, “This research demonstrates how neuromodulation can reshape systemic metabolism and control inflammation. Targeting the vagus nerve is a promising therapeutic approach that could be translated into non-invasive treatments to alleviate cachexia and enhance cancer therapy outcomes.”

The study reveals the essential role of the brain-liver axis in cancer-associated cachexia and presents vagus nerve modulation as a practical, patient-accessible therapeutic strategy. This innovation paves the way for future clinical trials and could redefine cachexia management in oncology.

AI also assesses Dutch mammograms better than radiologists

2025-08-14
AI is detecting tumors more often and earlier in the Dutch breast cancer screening program. Those tumors can then be treated at an earlier stage. This has been demonstrated by researchers led by Radboud university medical center in a study published in The Lancet Digital Health. The use of AI could reduce workload and save millions of euros annually. Previous research in Sweden had already shown that AI detects breast cancer on mammograms more frequently than radiologists. Moreover, AI can reduce the workload for radiologists. Now, it appears that AI can also replace the second radiologist in the Dutch breast cancer screening program. This ...

High triglycerides drive life-threatening aortic aneurysms, study in mice finds

2025-08-14
High levels of triglycerides, the most common type of fat in the body and the foods we eat, directly cause abdominal aortic aneurysms, according to a study in mouse models led by Michigan Medicine. Researchers identified triglyceride-rich lipoproteins and proteins that regulate triglyceride metabolism, including APOC3 and ANGPTL3, as causal drivers of abdominal aortic aneurysm. The study challenges the longstanding belief that triglycerides are merely biomarkers of vascular disease and instead demonstrates that they play a direct and pathogenic role in aneurysm development, ...

Minimally invasive procedure relieves painful symptoms of knee osteoarthritis

2025-08-14
A procedure performed under mild sedation in less than two hours by an interventional radiologist relieves chronic knee pain caused by osteoarthritis, an NYU Langone Health study shows. As they gradually break down, knee joints in people with osteoarthritis are known to become inflamed, which triggers the growth of small blood vessels (angiogenesis) and increased blood flow to joints. The study procedure, called genicular artery embolization, kept this abnormal blood flow from ferrying in immune cells that cause the inflammation and related pain.  For the new study, the researchers delivered chemical beads (biocompatible hydrogels) ...

New research reveals the spark that ignites Mediterranean marine heatwaves

2025-08-14
The Mediterranean Sea is particularly susceptible to marine heatwaves – such as the record breaking 2022 heatwave which was characterized by anomalously high sea surface temperatures – due to the interplay of air-sea heat fluxes and local oceanographic processes, leading to significant impacts on marine ecosystems and coastal communities.  A new study, led by CMCC, brings the scientific community one step closer to identifying the driving forces behind these events. Analyzing over hundreds of marine heatwave events identified through advanced satellite data and clustering analysis, the study shows that persistent ...

It performs real-time frequency domain computation for tasks like radio signal decoding, radar target tracking and digital data processing, ...

Teens with higher blood levels of PFAS regain more weight after bariatric surgery, study finds

2025-08-14
Adolescents who undergo bariatric surgery face a higher risk of weight regain, which can undermine treatment success and long-term health, if they have elevated blood levels of per- and polyfluoroalkyl substances (PFAS) prior to the procedure, according to new USC research. PFAS are manufactured chemicals used in consumer products that accumulate in the body over time and are increasingly linked to a range of health concerns, including kidney problems, liver damage and various ...

Discovery of ‘weird looking’ otter poo reveals how these animals shape nearby ecologies

2025-08-14
North American river otters have lived for a long time in Chesapeake Bay, yet relatively little is known about how their surroundings impact them. So what does daily life for river otters on the Atlantic coast of the US look like? What do they eat? Where do they socialize? Where do they go to poo? Researchers in Maryland decided to investigate and have now published their findings in Frontiers in Mammal Science. “River otters in the Chesapeake Bay eat a wide range of animals, including those that live in the water and on land. Parasites, ...

River otters unfazed by feces and parasites while eating… and that’s good for ecosystems

2025-08-14
North American river otters have terrible hygiene when it comes to their food. They eat, play and defecate in the same place. But their unhealthy habits make them ideal for detecting future health threats in the environment, according to scientists. In a new study published Aug. 14, Smithsonian scientists analyzed the otters’ diets and “latrine” habitats in the Chesapeake Bay for the first time. They discovered river otters often eat food riddled with parasites—and that may not be a bad thing for the larger ecosystem. “River otters are impressive apex predators that play a vital role in ecosystems,” ...

Back from the brink of extinction

2025-08-14
Kyoto, Japan -- For many endangered species, population decline to the brink of extinction leads to inbreeding, exposing a species to deleterious recessive mutations that severely limit its potential to recover. But the red-headed wood pigeon, endemic to the Ogasawara Islands in Japan, followed a different trajectory. Although this pigeon population fell to below 80 individuals in the 2000s, it began to increase markedly after the removal of an introduced predator, the feral cat. Such a remarkable recovery raised questions regarding inbreeding, and why harmful mutations that could cause inbreeding depression, ...
