Associations between granins (secretogranin II (SgII) and chromogranin A and B (CgA and CgB)) and gonadotrophins (LH and FSH) have been reported in rodents and they may interact to facilitate differential storage and secretion of LH and FSH. This study investigated the relationship between granins and gonadotrophins in sheep at different stages of the oestrous cycle. Thirty-four cycling ewes ha...

AIM To explore Trichostatin A (TSA) effect on SGC-7901 gastric cancer cells. METHODS MTT, fluorescence microscopy, and flow cytometry were used to assess TSA effect on cell growth and apoptosis in SGC-7901. Immunocytochemistry was used to evaluate the expression of acetylated histone H4 in SGC-7901 cells.Gene expression profile was determined by microarray assays. Glycoprotein hormones alpha ...

Chromogranin A (CgA (CHGA)) is the major soluble protein co-stored and co-released with catecholamines and can function as a pro-hormone by giving rise to several bioactive peptides. This review summarizes the physiological functions, the pathogenic implications, and the recent use of these molecules as biomarkers in several pathological conditions. A thorough literature review of the electroni...

Adrenocortical carcinoma is an uncommon and aggressivemalignancy. Despite a high frequency of metastasis, cutaneousmetastasis of adrenocortical carcinoma is rare with only isolatedcase reports. Its diagnosis can be challenging based solely onhistopathological findings. Yet, the clinical history in combinationwith an immunohistochemical panel consisting of inhibin,vimentin, chromogranin, synapto...

Aggregation chaperones, consisting of secretory proteins that contain a hexa-histidine epitope tag, enhance the calcium-induced aggregation of regulated secretory proteins and their sorting to secretory granules. The goal of this study was to gain a better understanding of this unusual aggregation mechanism. Hexa-histidine-epitope-tagged secreted alkaline phosphatase, an aggregation chaperone, ...
