How does telomerase research relate to cancer today?
Telomerase is a key target in cancer research because about 90% of human cancers reactivate telomerase to achieve immortality. This makes it an attractive therapeutic target. For example, drugs that inhibit telomerase are being tested to limit tumor growth. However, it's a complex relationship—some cancer cells use alternative lengthening of telomeres, or ALT, a telomerase-independent pathway. My lab has studied how telomerase is regulated in cancer, showing that its activation often involves mutations in the TERT promoter, which controls the enzyme's production. This has led to diagnostic tools and potential treatments. But we must be cautious: inhibiting telomerase might also affect stem cells, causing side effects. The key is to follow the data—understanding the nuances of telomerase biology in different cancers will guide smarter therapies. Basic research remains essential for these advances.
