Glioblastoma Drug Resistance Pathway Identified

Researchers identified a key signaling pathway, PI3K-beta, responsible for chemotherapy resistance in glioblastoma. Blocking this pathway makes tumor cells more sensitive to temozolomide, a standard chemotherapy drug. This discovery offers a potential new approach to treating glioblastoma, a deadly brain cancer, by overcoming drug resistance and improving patient outcomes.
