UNC Lineberger Comprehensive Cancer Center has been awarded up to $28 million by the Advanced Research Projects Agency for Health (ARPA-H) to lead the development of a next-generation clinical trial for breast cancer that has spread to other parts of the body. The new trial design will adapt treatment plans in near real-time by analyzing changes in each patient’s cancer and matching it to the most promising therapy.
A recent review in eGastroenterology explores how key epigenetic changes—including DNA methylation, histone modifications, and noncoding RNAs—drive the development and progression of hepatocellular carcinoma (HCC). These mechanisms influence oncogene activation, tumor suppressor gene silencing, and contribute to therapy resistance. The paper highlights how DNA hypermethylation silences tumor suppressors, while histone modifications regulate gene transcription. Furthermore, dysregulated noncoding RNAs modulate signaling pathways critical to hepatocarcinogenesis. Importantly, emerging epigenetic therapies, including inhibitors and RNA-targeting agents, offer potential in precision oncology. These findings underscore the relevance of epigenetic research in improving HCC diagnosis, prognosis, and treatment.
An international team of scientists, co-led by researchers at Trinity College Dublin and the University of Florida, has cracked a decades-old mystery in human biology: how our bodies absorb a micronutrient that we rely on for everything from healthy brain function to guarding against cancer. Queuosine, a microscopic molecule first discovered in the 1970s, is a vitamin-like micronutrient that we can't make ourselves but can only get from food and our gut bacteria. It’s vital to our health, yet its importance went unnoticed for decades. Now, in a study published this week in leading international journal Proceedings of the National Academy of Sciences (PNAS), researchers have discovered the gene that allows queuosine to enter the cells, a discovery that opens the door for potential therapies to be created to leverage the micronutrient’s role in cancer suppression, memory and how the brain learns new information.
The American Society for Radiation Oncology (ASTRO), the leading organization for physicians who treat patients using radiation therapy, recently welcomed Karen Davis as its first Vice President of Business Development and Marketing. “Karen’s proven record of building high-impact partnerships and mobilizing resources for mission-driven organizations will help ASTRO accelerate initiatives that improve care for patients with cancer worldwide,” said ASTRO CEO Vivek S. Kavadi, MD, MBA, FASTRO.
Salk Assistant Professor Deepshika Ramanan has been named a Rita Allen Foundation Scholar. The award will help fund her research on how maternal immune cells support lactation and shape long-term health outcomes for both mother and child.
