Signaling mechanism could be target for survival, growth of tumor cells in brain cancer

Researchers found that this mechanism — a type of signaling termed constitutive or non-canonical epidermal growth factor receptor (EGFR) signaling — is highly active in glioblastomas, the most common type of adult brain cancer and a devastating disease with a poor prognosis. When activated in cancer cells, it protects the tumor cells, making them more resistant to chemotherapy treatment. The pathway may also have implications for other types of lung and breast cancers where overexpression of EGFR is a factor. “Abnormal EGFR signaling, a common and key feature of human cancer, is of considerable interest both for a role in the growth of malignant cells and as a target for treatment,” said Dr…
