Overview:
This article discusses how circadian rhythms impact various biological processes, including cancer cell behavior. The review focuses on how the circadian clock influences the tumor microenvironment (TME) throughout the metastatic process, covering aspects such as:
- Remodeling at the invasive edge
- Intravasation and circulation
- Extravasation and colonization
Key mechanisms explored include:
- Extracellular matrix (ECM) turnover
- Cancer-associated fibroblasts (CAFs)
- Tumor-associated macrophages (TAMs)
- Immune suppression
- Angiogenesis
- Circulating tumor cells (CTCs)
- Endothelial adhesion
- Exosomes
- Cell-cycle progression
The authors propose that disruptions in circadian rhythms may lead to vulnerabilities within metastatic niches. They suggest that chronotherapy, or timing treatments to align with biological rhythms, could enhance the effectiveness of existing cancer therapies.
