The compound thymoquinone (TQ) selectively kills prostate cancer cells at advanced stages, according to a new study published in Oncogene. Led by researchers at Kanazawa University, the study reports that prostate cancer cells with a deletion of the SUCLA2 gene can be therapeutically targeted. SUCLA2-deficient prostate cancers represent a significant fraction of those resistant to hormone therapy or metastatic, and a new therapeutic option for this disease would have immense benefits for patients.
Hormone therapy is often chosen for the treatment of metastatic prostate cancer but nearly half of patients develop resistance to the treatment in as little as 2 years. A mutation in RB1, a tumor suppressor gene that keeps cell growth under control, has been pegged as a particularly strong driver of treatment resistance and predicts poor outcome in patients.
“Mutations in tumor suppressor genes are enough to induce initiation and malignant progression of prostate cancer, but
