Targeting Angiopoietin‑2/Tie2 to limit liver spread of pancreatic neuroendocrine tumors

Angiopoietin-2/Tie2 signaling regulation of liver metastasis in pancreatic neuroendocrine tumors

NIH-funded research Columbia University Health Sciences · NIH-11211625

The team is looking at whether blocking a blood‑vessel protein called Angiopoietin‑2 can reduce liver spread in people with pancreatic neuroendocrine tumors.

What this research studies

Scientists are studying how Angiopoietin‑2 and its receptor Tie2 make blood vessels leaky in pancreatic neuroendocrine tumors and how that helps cancer spread to the liver. In mouse models, blocking Angiopoietin‑2 reduced liver tumor growth and improved survival. The project will examine how these blood‑vessel changes keep immune cells out of tumors and make immunotherapy less effective, and test whether combining Angiopoietin‑2 blockade with immune approaches can improve outcomes. The goal is to identify strategies that could lead to new treatments to prevent or slow liver metastases.

Who could benefit from this research

Good fit: People with pancreatic neuroendocrine tumors, especially those with existing liver metastases or at high risk for liver spread, would be the most relevant candidates.

Not a fit: Patients with other types of pancreatic cancer or non‑neuroendocrine tumors are unlikely to benefit from Angiopoietin‑2‑targeted approaches.

Why it matters

Potential benefit: If successful, this work could lead to treatments that prevent or slow liver metastases and make immunotherapies work better for people with PanNETs.

How similar studies have performed: Prior preclinical studies link Angiopoietin‑2 to vascular instability and reduced metastasis when blocked in animal models, but benefit in people with PanNETs has not been proven.
