A deficient pancreatic β-cell mass increases the risk of type 2 diabetes mellitus. Here, we investigated the effects of testosterone on the development of pancreatic β-cell mass in male rats. The β-cell mass of male rats castrated at 6 weeks of age was reduced to ~30% of that of control rats at 16 weeks of age, and castration caused glucose intolerance. Loss of β-cell mass occurred due to decreases in islet density/pancreas and β-cell cluster size. Castration was negatively associated with the number of Ki67-positive β-cells and positively associated with the number of TUNEL-positive β-cells...

OBJECTIVES: The side population (SP) contains cells with stem cell/progenitor properties. Previously, we observed that the mouse pancreas SP expanded after pancreatic injury. We aimed to characterize the SP in human pancreas as a potential source of stem cells. METHODS: Human organ donor pancreata were fractionated into islets and exocrine tissue, enriched by tissue culture and dispersed into single cells. Cells were phenotyped by flow cytometry, and the SP was defined by efflux of fluorescent dye Hoechst 33342 visualized by ultraviolet excitation...

BACKGROUND: Hemoglobin is a lipid oxidation promoter in fish muscle. Phospholipase A2 (PLA2; EC 3.1.1.4), is linked to increased resistance to lipid oxidation of frozen-thawed cod fillets via an unknown mechanism. The aims of this study were to investigate the mechanism of hemoglobin-mediated lipid oxidation with a focus on ferryl hemoglobin and methemoglobin, the pro-oxidative hemoglobin species, and to examine how porcine pancreatic PLA2 inhibits hemoglobin-mediated lipid oxidation in washed cod muscle (WCM)...

Proinsulin is synthesized in the endoplasmic reticulum (ER) in pancreatic β cells and transported to the Golgi apparatus for proper processing and secretion into plasma. Defects in insulin biogenesis may cause diabetes. However, the underlying mechanisms for proinsulin transport are still not fully understood. We show that β cell-specific deletion of cTAGE5, also known as Mea6, leads to increased ER stress, reduced insulin biogenesis in the pancreas, and severe glucose intolerance in mice. We reveal that cTAGE5/MEA6 interacts with vesicle membrane soluble N-ethyl-maleimide sensitive factor attachment protein receptor Sec22b...

Human antigen R (ELAVL1, HuR) is perhaps the best-characterized RNA-binding protein. Through its overexpression in various tumor types, HuR promotes post-transcriptional regulation of target genes in multiple core signaling pathways associated with tumor progression. The role of HuR overexpression in pancreatic tumorigenesis is unknown and led us to explore the consequences of HuR overexpression using a novel transgenic mouse model that has a >2-fold elevation of pancreatic HuR expression. Histologically, HuR overexpressing pancreas displays a fibro-inflammatory response and other pathological features characteristic of chronic pancreatitis...
