Abstract:
For both men and women, colorectal cancer (CRC) is the second leading cause of cancer death in the United States, primarily as a consequence of limited therapies for metastatic disease. The aryl hydrocarbon receptor (AhR) is a ligand-dependent transcription factor with diverse functions in detoxification of xenobiotics, inflammatory responses, and tissue homeostasis. Emerging evidence indicates that AhR also plays an important role in regulating intestinal cell proliferation and tumorigenesis. Here, we review both the pro- and anti-carcinogenic properties of AhR signaling and its potential role as a therapeutic target in CRC.
Insights
Colorectal cancer (CRC) remains a leading cause of death due to limited treatments for metastatic disease. This review explores the dual role of the aryl hydrocarbon receptor (AhR) in CRC and its potential as a therapeutic target.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Colorectal cancer (CRC) is a significant cause of cancer mortality in the US.
- Limited therapeutic options exist for metastatic CRC.
- The aryl hydrocarbon receptor (AhR) is a transcription factor involved in various cellular processes.
Purpose of the Study:
- To review the multifaceted roles of AhR signaling in colorectal cancer.
- To discuss the potential of AhR as a therapeutic target for CRC.
Main Methods:
- Literature review of existing studies on AhR signaling in CRC.
- Analysis of both pro- and anti-carcinogenic functions of AhR.
Main Results:
- AhR exhibits both tumor-promoting and tumor-suppressing activities in CRC.
- AhR signaling influences intestinal cell proliferation and tumorigenesis.
- Evidence suggests AhR's complex involvement in CRC development.
Conclusions:
- AhR signaling presents a complex landscape in colorectal cancer.
- Targeting AhR pathways may offer novel therapeutic strategies for CRC.
- Further research is needed to elucidate AhR's precise role and therapeutic potential in CRC.
