Description

Ioanna Tsea and co-authors test a drug that may weaken the hardest form of a childhood brain tumour, in a 2024 paper. Medulloblastoma is the most common high-grade brain tumour in children, and its group 3 form has the worst outlook. Many group 3 tumours overproduce MYC, a growth-driving protein that drugs have failed to block directly. The team instead blocked an enzyme the tumour needs to build DNA parts.

The drug, brequinar, jams that enzyme, called DHODH. The authors first found the enzyme running high in group 3 and a second tumour subgroup, where it tracked with MYC and poor survival. They then tested the drug on seven tumour cell lines in dishes. Finally, they built a new zebrafish model carrying the tumour to watch the drug's effect and safety in a living body, a step toward trials in children.
