Researchers Identify Key Pathway in Aggressive Pediatric Brain Cancer

Researchers found that two members of the LIN28 family of genes were highly expressed in nearly 80% of samples from AT/RT patients and tumors themselves.

Working with cells taken from children with a very rare but ferocious form of brain cancer, Johns Hopkins Kimmel Cancer Center scientists have identified a genetic pathway that acts as a master regulator of thousands of other genes and may spur cancer cell growth and resistance to anticancer treatment.

Their experiments with cells from patients with atypical teratoid/rhabdoid tumor (AT/RT) also found that selumetinib, an experimental anticancer drug currently in clinical trials for other childhood brain cancers, can disrupt part of the molecular pathway regulated by one of these factors, according to a research team led by Eric Raabe, M.D., Ph.D., an assistant professor of oncology at the Johns Hopkins University School of Medicine.
