Substance in the blood is found to increase as early as two years before diagnosis of pancreaticcancer
). Samples were balanced for sex ratio and were used to construct biomarker models at the time of diagnosis.Plasma samples were stored at −80°C before and between enzyme-linked immunoassay and multiplex biomarker assay measurements. Collagen IV and endostatin were analyzed using Serum Collagen IV EIA and Human Endostatin Quantikine ELISA kit , respectively. CA19-9 and CEA were measured using the multiplex bead kit WideScreen Human Cancer Panel 1 .
There were 39 individuals in the control group without PDAC that also contributed multiple NSHDS samples. These were used to control for individual fluctuations in marker expression independent of PDAC. The mean delta across all controls was subtracted from case deltas then divided by the standard deviation of all control deltas to provide a “Case vs. Control Z-score”. These values were plotted against time to diagnosis. Graphs were smoothed by a Savitzky–Golay filter.Conceptualization, P.N., H.

d-Amino Acids and Classical Neurotransmitters in Healthy and Type 2 Diabetes-Affected Human Pancreatic Islets of LangerhansThe pancreatic islets of Langerhans are clusters of cells that function as endocrine units synthesizing and releasing insulin and a range of additional peptide hormones. The structural and chemical characteristics of islets change during type 2 diabetes development. Although a range of metabolites including neurotransmitters has been reported in rodent islets, the involvement of these cell-to-cell signaling molecules within human pancreatic islets in the pathophysiology of type 2 diabetes is not well known, despite studies suggesting that these molecules impact intra- and inter-islet signaling pathways. We characterize the enigmatic cell-to-cell signaling molecules, d-serine (d-Ser) and d-aspartate (d-Asp), along with multiple classical neurotransmitters and related molecules, in healthy versus type 2 diabetes-affected human islets using capillary electrophoresis separations. Significantly reduced d-Ser percentage and gamma-aminobutyric acid (GABA) levels were found in type 2 diabetes-affected islets compared to healthy islets. In addition, the negative correlations of many of the signaling molecules, such as d-Ser percentage (r=−0.35), d-Asp (r=−0.32), serotonin (r=−0.42), and GABA (r=−0.39) levels, with hemoglobin A1c (HbA1c) levels and thus with the progression of type 2 diabetes further demonstrate the disruption in intra- or inter-islet signaling pathways and suggest that these cell-to-cell signaling molecules may be potential therapeutic targets.
