Study shows brain cancer aligns with body clock to enhance growth

New research reveals that glioblastoma, a common and aggressive brain cancer, synchronizes its growth with the body's circadian rhythms. This allows the tumor to respond to daily hormone fluctuations, particularly cortisol, which aids its progression. Blocking these circadian signals significantly slowed tumor growth in both lab cells and animal models. The study suggests that the timing of treatments, such as the steroid dexamethasone, can influence tumor response, with evening doses potentially suppressing growth compared to morning doses. The findings highlight the importance of considering circadian rhythms in cancer treatment. Researchers aim to explore how timing can optimize therapies for glioblastoma and improve patient outcomes.
