zymogen/obesity

In the present work, we induced obesity in rats with high-energy-starch diet and studied exocrine pancreas response. The zymogen granule (ZG) or purified plasma membrane (PM) from the exocrine pancreas was used for the isolation of the detergent-resistant membranes (DRMs). Based on high content of

Mutations in the PCSK1 gene encoding prohormone convertase 1/3 (PC1/3) are strongly associated with obesity in humans. The PC1/3(N222D) mutant mouse thus far represents the only mouse model that mimics the PC1/3 obesity phenotype in humans. The present investigation addresses the cell biology of the

Type 2 diabetes mellitus (T2DM) is caused by the failure of the pancreatic beta-cell to secrete sufficient insulin to compensate a decreased response of peripheral tissues to insulin action. The pathological events causing beta-cell dysfunctions are only poorly understood and early markers that

Blue honeysuckle (BH, Lonicera caerulea) is used as a traditional medicine in Russia, Japan and China, but is not commonly considered as an edible berry in Europe, USA or Korea. BH has been revealed to decrease serum cholesterol and triacylglycerol (triglyceride or TG) levels through the activation

Proopiomelanocortin (POMC) is a precursor to various, bioactive peptides including ACTH, beta LPH, alpha MSH, and beta endorphin (beta END). Processing of POMC at dibasic residues is tissue-specific and is performed by either PC1 alone (resulting in ACTH and beta LPH, anterior pituitary

Compound-induced pancreatic injury is a serious liability in preclinical toxicity studies. However, its relevance to humans should be cautiously evaluated because of interspecies variations. To highlight such variations, we evaluated the species- and dose-specific pancreatic responses and

BACKGROUND Proprotein convertase 1/3 (PC1/3) is one of the endoproteases initiating the proteolytic activation of prohormones and proneuropeptides in the secretory pathway. It is produced as a zymogen that is subsequently modified by activity-determining cleavages at the amino and the carboxyl

PC1/3 is a neuroendocrine-specific member of the mammalian subtilisin-like proprotein convertase family. This seven-member family is involved in the endoproteolytic cleavage of a large number of precursor proteins including prohormones, proneuropeptides, zymogens, and proreceptors. PC1/3 is

Studies initiated 30 years ago emphasized that dilute blood clot lysis time was longer in obese diabetic patients than in normal weight diabetics. It was also later reported that when compared to obese women with gluteal and femoral adiposity, the age matched men with abdominal obesity displayed a

The localization of the protein-disulfide interchange enzyme, glutathione-insulin transhydrogenase (GIT), in rat and mouse pancreas was studied by protein A-gold immunocytochemistry, immunodiffusion, and assay of enzymatic activity. Immunocytochemistry on tissue sections using antibody to GIT and

The major components of tea may be significantly influenced according to the type of fermentation, and consequently the effects of different teas will differ. We examined whether green tea fermented with Aquilariae Lignum (fGT) shows a stronger anti-diabetic effect than unfermented green tea (GT) on
