Endoscopic Ultrasound for the Management of Pancreatic Neuroendocrine Tumors: Diagnosis, Treatment, and Future Perspectives

Journal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Pancreatic neuroendocrine tumors (PanNETs) are increasingly diagnosed, reflecting greater clinical awareness, improved imaging, and revised classification. This review summarizes evidence on epidemiology, diagnostic workup, and endoscopic ultrasound (EUS)–guided management of PanNETs, encompassing diagnostic evaluation, tissue acquisition, and

Human prostate sphere-forming cells represent a subset of basal epithelial cells capable of glandular regeneration in vivo. [PDF]

, 2009
BackgroundProstate stem/progenitor cells function in glandular development and maintenance. They may be targets for tumor initiation, so characterization of these cells may have therapeutic implications.

Chromogranin A in the pancreatic islet [PDF]

, 1986
Chromogranin A (CGA) is the major soluble protein within secretory vesicles of chromaffin cells. A polyclonal antiserum was raised against bovine CGA and characterized in two-dimensional immunoblots. Cellular and subcellular distribution of CGA in bovine

Ca2+-Stimulated Catecholamine Release from alpha-Toxin Permeabilized PC12 Cells [PDF]

, 1987
Two possible cellular pathways of catecholamines from the chromaffin vesicles of PC 12 cells to the surrounding medium are explored in this study. The direct one circumventing the cytoplasm can be activated in a-toxin-permeabilized cells with micromolar ...

The organisation of the mouse chromogranin B (secretogranin I) gene

FEBS Letters, 1990
A cosmid clone containing the gene for mouse chromogranin B (secretogranin I), a secretory protein found in secretory granules of most endocrine cells and neurons, was isolated and sequenced. The chromogranin B protein was found to be encoded by 5 exons which correspond to the cleaved signal peptide, the short N‐terminal sequence preceding the ...
