Scientists have been exploring the connection between tricyclic antidepressants and brain cancer since the early 2000s. There’s some evidence that the drugs can lower one’s risk for developing aggressive glioblastomas, but when given to patients after diagnosis in a small clinical trial, the antidepressants showed no effect as a treatment.
In a study appearing in Cancer Cell on September 24, Swiss researchers find that antidepressants work against brain cancer by excessively increasing tumor autophagy (a process that causes the Cancer Cells to eat themselves). The scientists next combined the antidepressants with blood thinners—also known to increase autophagy—as a treatment for mice with the first stages of human glioblastoma. Mouse lifespan doubled with the drug combination therapy, while either drug alone had no effect.
