Chromogranin A and chromogranin B in pancreatic neuroendocrine tumors

Medical alphabet, 2020
For the first time in Russia a comparative study of chromogranin A (CgA) and chromogranin B (CgB) in neuroendocrine tumors (NETs) of the pancreas was performed. We examined 50 primary patients with pancreatic NETs and 42 healthy people. The determination of CgA and CgB was performed in blood serum using standard enzyme-linked immunoassay test-systems ...

Cellular distribution and amount of chromogranin A in bovine endocrine pancreas [PDF]

, 1988
We determined the cellular distribution and the amount of chromogranin A in endocrine cells of bovine pancreas using a polyclonal antibody against bovine adrenomedullary chromogranin A. The relative amounts of chromogranin A in the different cells of the

Digital Spatial Profiling Reveals Functional Shift of Enterochromaffin Cell in Patients With Ulcerative Colitis

Frontiers in Cell and Developmental Biology, 2022
As a major component of the enteroendocrine system, enterochromaffin (EC) cells play a key role in ulcerative colitis (UC). However, the scarcity of EC cells has limited the investigation of their function.

Immunological characterization of chromogranins A and B and secretogranin II in the bovine pancreatic islet [PDF]

, 1987
Antisera against chromogranin A and B and secretogranin II were used for analysing the bovine pancreas by immunoblotting and immunohistochemistry. All three antigens were found in extracts of fetal pancreas by one dimensional immunoblotting. A comparison

Effects of pH and Ca2+ on Heterodimer and Heterotetramer Formation by Chromogranin A and Chromogranin B [PDF]

Journal of Biological Chemistry, 1996
The two major proteins of the secretory vesicles of neuroendocrine cells, chromogranin A (CGA) and chromogranin B (CGB), have been shown to undergo pH- and Ca2+-dependent conformational changes and aggregation and have been suggested to play essential roles during secretory vesicle biogenesis in the trans-Golgi network.

Ca2+ binding to Chromaffin Vesicle Matrix Proteins [PDF]

, 1986
Recently we found that Ca2+ within chromaffin vesicles is largely bound [Bulenda, D., & Gratzl, M. (1985) Biochemistry 24, 7760-77651. In order to explore the nature of these bonds, we analyzed the binding of Ca2+ to the vesicle matrix proteins as well ...
