Human Meningiomas Reveal No Evidence of Neuroendocrine Differentiation. [PDF]

APMIS
ABSTRACT Meningiomas are heterogeneous tumors and studies suggest that meningiomas might be part of MEN1 syndrome. The tumors express somatostatin receptors (SSTRs) comparable to that seen in neuroendocrine neoplasms. We aimed to explore neuroendocrine differentiation in meningiomas by investigating the following neuroendocrine markers: neural cell ...

The role of chromogranins in the secretory pathway

Biomolecular Concepts, 2013
Chromogranins (Cgs) are acidic proteins implicated in several physiological processes, including the biogenesis and sorting of secretory vesicles, the generation of bioactive peptides, and the accumulation of soluble species inside large dense core ...

Chromogranin A in neurons of the rat cerebellum and spinal cord: quantification and sites of expression [PDF]

, 1992
Chromogranin A (CGA) is an abundant protein of dense-cored secretory vesicles in endocrine and neuronal cells. The present study, for the first time, compares CGA of neurons of the central nervous system with the CGA of adrenal origin.

Synaptophysin and synaptoporin expression in the developing rat olfactory system [PDF]

, 1993
The expressions of two closely related synaptic vesicle antigens synaptophysin and synaptoporin were examined in the olfactory system of the adult rat and during pre- and postnatal development.

Chromogranin/secretogranin proteins in murine heart: myocardial production of chromogranin A fragment catestatin (Chga364–384) [PDF]

, 2010
In the heart, the secretory granules containing the atrial natriuretic peptides (ANP) and B-type myocardial natriuretic peptide (BNP) provide the basis for the endocrine function of this organ.

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 ...

Faecal secretogranin and chromogranin levels persist over time and are unrelated to disease history and outcome in patients with ulcerative colitis

Cogent Medicine, 2018
Objectives: Chromogranins (Cg) and secretogranins (Sg) are expressed by endocrine cells and may be important for the pathophysiology of ulcerative colitis (UC).

Matrix-free calcium in isolated chromaffin vesicles [PDF]

, 1985
Isolated secretory vesicles from bovine adrenal medulla contain 80 nmol of Ca2+ and 25 nmol of Mg2+ per milligram of protein. As determined with a Ca2+-selective electrode, a further accumulation of about 160 nmol of Ca2+/mg of protein can be attained ...

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 ...
