Summary
Glioblastoma growth is influenced by the body's internal clock. Timing medication like Dexamethasone can impact tumor progression, suggesting circadian rhythms are key in brain tumor treatment.
Area of Science:
- Neuro-oncology
- Chronobiology
- Molecular biology
Background:
- Glioblastoma (GBM) is an aggressive brain tumor with poor patient survival.
- Recent studies suggest time-of-day administration of chemotherapy may impact GBM outcomes.
- Circadian rhythms, the body’s natural 24-hour cycles, are increasingly recognized for their role in physiological processes.
Conclusions:
- Glioblastoma (GBM) entrains to the host’s circadian rhythm via brain signaling.
- Host circadian cues, particularly glucocorticoids, modulate GBM growth.
- Targeting circadian signaling pathways presents a potential therapeutic strategy for glioblastoma.

Circadian Rhythms and Gene Regulation
4.0K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Hypoglycemia and Glucagon
256
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
115
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...
