Pediatric diffuse midline gliomas (DMGs) are highly aggressive brain tumors with a universally fatal prognosis, often taking the lives of children within a year of diagnosis. Despite extensive efforts, radiation therapy remains the only treatment that can extend survival, but tumor progression is inevitable. Recent advances in adult cancer research have revealed that a biological process called cellular senescence plays a significant role in how cancers develop, resist treatment, and recur.

Brain tumors are a major cause of cancer-related deaths in children, with high-grade gliomas (HGG) being particularly lethal. These tumors often have mutations in histone genes, occurring in a specific pattern during childhood development. Our research focuses on a subset called DHG-H3G34, marked by H3G34RV mutations. Our initial data reveal that these tumors have a cell population resembling interneurons in the brain, with altered gene expression and communication patterns. In experiments, DHG-H3G34 cells exhibited features associated with tumor invasion and resistance.

Ewing sarcoma is a group of bone and soft tissue cancers that can occur in children, adolescents, and young adults. The high response rates to DNA-damaging chemotherapy suggest that there may be defects in DNA damage repair pathways that make Ewing sarcoma cells susceptible to chemotherapy-induced DNA damage. However, despite these high response rates, there is still an urgent need for new treatment options for Ewing sarcoma, particularly for patients with relapsed and/or refractory disease.
