The measurement of its concentrations is also used to monitor pancreatic carcinoma therapy and to predict the recurrence of pancreatic tumors. Insulin helps the cells to take in glucose. Only a few PP-cells or some secretion granules of PP-cells are immunoreac- tive for CGA (arrows in A and B). Background. Pancreatic polypeptide also functions as a hepatic glucose regulator. It regulates pancreatic secretion activities, and also impacts liver glycogen storage and gastrointestinal secretion. The measurement of pancreatic polypeptide is also used to monitor pancreatic carcinoma therapy and to predict the recurrence of pancreatic tumors. One of the functions of the pancreas is to produce two hormones: insulin and pancreatic polypeptide. anti-Pancreatic Polypeptide (PP) rabbit polyclonal, serum.
