Using daily body rhythms to improve glioblastoma treatment

Circadian interventions against glioblastoma

NIH-funded research Washington University · NIH-11247505

This project explores whether giving chemotherapy at specific times of day tied to the body's daily rhythms can help people with glioblastoma respond better to treatment.

What this research studies

From a patient's perspective, the team is studying how daily brain activity rhythms affect glioblastoma growth and treatment response. In the lab they use mice implanted with human or mouse glioblastoma cells that have been engineered to report their internal clock, and they can control the animals' daily neuronal activity, hormones, and sleep-wake patterns. They will test whether timing temozolomide and other treatments to these rhythms, or targeting clock-related pathways, slows tumor progression. The researchers will also look for sex differences in how circadian timing affects tumor growth and treatment benefit.

Who could benefit from this research

Good fit: People with glioblastoma, particularly those treated with temozolomide, would be the most likely candidates for any future clinical trials based on this work.

Not a fit: Patients with other types of brain tumors or tumors that do not respond to circadian-based approaches may not benefit from these findings.

Why it matters

Potential benefit: If successful, this work could lead to scheduling chemotherapy at times of day that make treatment more effective for glioblastoma patients.

How similar studies have performed: Chronotherapy has shown benefits in cancers like colorectal cancer and leukemia, and early laboratory data suggest temozolomide’s effectiveness varies by time of day, but clinical tests in brain tumors are still novel.
