Pancreastatin

Pancreastatin is a peptide derived from chromogranin A, an established biomarker used in the assessment and monitoring of neuroendocrine tumours (NETs). Produced by neuroendocrine cells, pancreastatin has shown potential as a blood-based biomarker for NET detection, monitoring and prognosis. It may also influence blood glucose regulation through its effects on insulin secretion and insulin resistance.

Pancreastatin

Why Pancreastatin matters

Pancreastatin levels can be elevated in patients with neuroendocrine tumours, and measurement may help support their diagnosis and monitoring. Unlike chromogranin A, pancreastatin levels are not affected by proton pump inhibitors, medicines commonly used to reduce stomach acid. This may make it a more reliable biomarker in some clinical situations. Elevated pancreastatin levels have also been reported in people with diabetes and may reflect metabolic stress associated with insulin resistance. However, its role in human diabetes is not yet fully understood and requires further investigation.
