A new druggable cancer target: RNA-binding proteins on the cell surface
In 2021, research led by Ryan Flynn, MD, PhD, and his mentor, Nobel laureate Carolyn Bertozzi, PhD, opened a new chapter in biology, characterizing a new kind of player on the cell surface: glycoRNAs. Extending this discovery recently in Cell, Flynn and colleagues showed that glycoRNAs form highly organized clusters with RNA-binding proteins on the ...

Forecasting the future for childhood cancer survivors
Children are much more likely to survive cancer today than 50 years ago. Unfortunately, as adults, many of them develop cardiovascular disease, secondary cancers, or both, believed to result from the toxic effects of chemotherapy and radiation. But the full risk picture for survivors hasn’t been clear. “Patients want to know how long they’ll live ... Read More about Forecasting the future for childhood cancer survivors
Pediatric high-grade gliomas: Research reveals effective targeting with avapritinib
Pediatric high-grade gliomas, particularly H3K27M diffuse midline gliomas (DMG), are aggressive malignant brain tumors with a poor prognosis. Previous research suggests that platelet-derived growth factor receptor alpha (PDGFRA) appears to play a multifaceted role in the pathogenesis of both adult and pediatric high-grade gliomas. Not only are genetic alterations of PDGFRA common in patients with ... Read More about Pediatric high-grade gliomas: Research reveals effective targeting with avapritinib
Blood across our lifetimes: An age-specific ‘atlas’ tells a dynamic story
The stem cells that form our blood, also known as hematopoietic stem cells (HSCs), are with us throughout our lives. A new study reveals how HSCs ramp up and pivot their activities depending on the body’s needs at the time, from before we’re born until old age. Researchers at Dana-Farber/Boston Children’s Cancer and Blood Disorders ... Read More about Blood across our lifetimes: An age-specific ‘atlas’ tells a dynamic story
Curbing blood cancers by teaching immune cells to kill mutant stem cells
Blood stem cells, which give rise to all of our blood cell types, undergo a quality assurance process after they’re born. As the lab of Leonard Zon, MD, director of the Stem Cell Research program at Boston Children’s, has documented, immune cells known as macrophages interact with each newly born cell. They engulf and eat ... Read More about Curbing blood cancers by teaching immune cells to kill mutant stem cells
A new anti-cancer strategy: Overriding tumor edits
Cancers are clever and often find ways to dodge people’s immune systems, making them hard to eradicate. Immunotherapies such as CAR-T cells and checkpoint inhibitors can sharpen the immune system’s attack and cure the cancer. But they don’t work for most solid tumors. We now know that tumors can edit their genes to evade immune ... Read More about A new anti-cancer strategy: Overriding tumor edits
Immunotherapy for children with primary liver carcinomas: Research offers new hope
Pediatric hepatocellular carcinoma (HCC) and fibrolamellar carcinoma are rare, aggressive forms of liver cancer that typically affect adolescents and young adults. Although some immunotherapy drugs are approved by the Food and Drug Administration as first-line treatments for HCC in adults, less is known about their effectiveness in treating pediatric liver carcinomas. Now, new research led ... Read More about Immunotherapy for children with primary liver carcinomas: Research offers new hope
After surgery for a brain tumor, Jenny is moving ahead — and giving back
“It might sound weird,” says Jenny Eckert, “but I’m very grateful that I got hit in the face with a soccer ball.” A year and a half ago, Jenny, then 9, was playing soccer when she accidentally took a hit to the head — twice. Concerned about a possible concussion, her parents, Vanessa and Scott, brought ... Read More about After surgery for a brain tumor, Jenny is moving ahead — and giving back
Boosting vaccines for the elderly with ‘hyperactivators’
As we age our immune systems start to flag, leaving us more susceptible to cancer and infections — and less responsive to vaccines and cancer immunotherapies. Going to the heart of the problem, Jonathan Kagan, PhD, a researcher in immunology at Boston Children’s Hospital, has identified a way to rejuvenate the elderly immune system. His ...

Exposing a tumor’s antigens to enhance immunotherapy
Successful immunotherapy for cancer involves activating a person’s own T cells to attack the tumor. But some tumors have a trick: They hide themselves from the immune system by preventing their antigens from being displayed, a necessary step in activating T cells. In new work published in Science, researchers in the Program in Cellular and ... Read More about Exposing a tumor’s antigens to enhance immunotherapy
