Regulation of Cancer Metastasis by TRAIL/Death Receptor Signaling
1Department of Hematology and Medical Oncology, Emory University School of Medicine and Winship Cancer Institute, Atlanta, GA 30322, USA.
Abstract:
Death ligands such as tumor necrosis factor-related apoptosis-inducing ligand (TRAIL; TNFSF10) and their corresponding death receptors (e.g., DR5) not only initiate apoptosis through activation of the extrinsic apoptotic pathway but also exert non-apoptotic biological functions such as regulation of inflammation and cancer metastasis. The involvement of the TRAIL/death receptor signaling pathway in the regulation of cancer invasion and metastasis is complex as both positive and negative roles have been reported. The underlying molecular mechanisms are even more complicated. This review will focus on discussing current knowledge in our understanding of the involvement of TRAIL/death receptor-mediated signaling in the regulation of cancer cell invasion and metastasis.
Insights
The TRAIL/death receptor pathway regulates cancer metastasis through complex mechanisms. This review explores its dual role in cancer cell invasion and spread.
Area of Science:
- Molecular Biology
- Oncology
- Cellular Signaling
Background:
- Death ligands, like tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), and their receptors initiate apoptosis.
- TRAIL/death receptor signaling also influences non-apoptotic functions, including inflammation and cancer metastasis.
- The role of TRAIL/death receptor signaling in cancer invasion and metastasis is complex, with reported positive and negative effects.
Purpose of the Study:
- To review the current understanding of TRAIL/death receptor signaling in regulating cancer cell invasion and metastasis.
- To elucidate the complex molecular mechanisms underlying the involvement of this pathway in cancer progression.
Main Methods:
- Literature review of studies on TRAIL/death receptor signaling.
- Analysis of research on the pathway's role in cancer cell invasion and metastasis.
- Synthesis of current knowledge on molecular mechanisms.
Main Results:
- The TRAIL/death receptor pathway has a multifaceted role in cancer metastasis.
- Both pro-metastatic and anti-metastatic functions have been attributed to this signaling pathway.
- Complex molecular mechanisms mediate these opposing effects.
Conclusions:
- The TRAIL/death receptor pathway is a critical regulator of cancer cell invasion and metastasis.
