Daily stress hormones may support glioblastoma growth and align its daily rhythms with the body

Updated

Abstract

Administering Temozolomide in the morning is associated with a 6-month increase in overall survival for glioblastoma patients.

  • Daily Dexamethasone can either promote or suppress glioblastoma growth depending on the time of administration and specific clock genes.
  • Blocking circadian signals, such as vasoactive intestinal peptide (VIP) or glucocorticoids, significantly slows glioblastoma growth and disease progression.
  • Both mouse and human glioblastoma models exhibit intrinsic circadian rhythms in clock gene expression that align with host signaling via glucocorticoids.
  • Glioblastoma appears to synchronize with the circadian cycle of the brain, which influences its growth through clock-controlled mechanisms.
