Human Diseases
Colorectal Cancer: CEA is the most widely used biomarker for colorectal cancer. Elevated levels are associated with disease progression and can be used for monitoring treatment response and detecting recurrence.
Lung Cancer: CEA is elevated in 40-50% of patients with non-small cell lung cancer and can be used as a prognostic marker.
Breast Cancer: CEA levels are elevated in 30-50% of breast cancer patients and correlate with disease stage.
Pancreatic Cancer: CEA is a useful marker for monitoring treatment response and detecting recurrence in pancreatic cancer patients.
Cellular Signaling Pathways
Cell Adhesion and Migration: CEA acts as a cell-cell adhesion molecule, influencing cell-cell interactions and cell migration processes.
Angiogenesis: CEA may play a role in promoting angiogenesis, the formation of new blood vessels, which is crucial for tumor growth and metastasis.
Immune Modulation: CEA can modulate immune responses by interacting with immune cells and affecting their activation and function.
Apoptosis: CEA may be involved in regulating apoptosis, or programmed cell death, which can contribute to tumor progression and metastasis.
