Abstract
In order to investigate the chronic effects of basic amino acids (BAA) on β-cell metabolism and insulin secretion, INS-1 β-cells were randomly assigned to cultures in standard medium (Con), standard medium plus 10 mM L-Arginine (Arg), standard medium plus 10 mM L-Histidine (His) or standard medium plus 10 mM L-Lysine (Lys) for 24 h. Results showed that insulin secretion was decreased by the Arg treatment but was increased by the His treatment relative to the Con group (p < 0.05). Higher BAA concentrations reduced the high glucose-stimulated insulin secretions (p < 0.001), but only Lys treatment increased the intracellular insulin content than that in the Con group (p < 0.05). Compared with Arg and Lys, the His treatment increased the mitochondrial key enzyme gene expressions including Cs, mt-Atp6, mt-Nd4l and Ogdh, and caused a greater change in the metabolites profiling (p < 0.05). The most significant pathways affected by Arg, His and Lys were arginine and proline metabolism, aminoacyl-tRNA biosynthesis and pyrimidine metabolism, respectively. Regression analysis screened 7 genes and 9 metabolites associated with insulin releases during BAA stimulations (p < 0.05). Together, different BAAs exerted dissimilar effects on β-cell metabolism and insulin outputs.

Abstract
Neurotransmitters are signaling molecules secreted by neurons to coordinate communication and proper function among different sections in the central neural system (CNS) by binding with different receptors. Some neurotransmitters as well as their receptors are found in pancreatic islets and are involved in the regulation of glucose homeostasis. Neurotransmitters can act with their receptors in pancreatic islets to stimulate or inhibit the secretion of insulin (β cell), glucagon (α cell) or somatostatin (δ cell). Neurotransmitter receptors are either G-protein coupled receptors or ligand-gated channels, their effects on blood glucose are mainly decided by the number and location of them in islets. Dysfunction of neurotransmitters receptors in islets is involved in the development of β cell dysfunction and type 2 diabetes (T2D).Therapies targeting different transmitter systems have great potential in the prevention and treatment of T2D and other metabolic diseases.

Carnosine Attenuates the Development of both Type 2 Diabetes and Diabetic Nephropathy in BTBR ob/ob Mice. Sci Rep 2017; 7:44492.

Abstract
We previously demonstrated that polymorphisms in the carnosinase-1 gene (CNDP1) determine the risk of nephropathy in type 2 diabetic patients. Carnosine, the substrate of the enzyme encoded by this gene, is considered renoprotective and could possibly be used to treat diabetic nephropathy (DN). In this study, we examined the effect of carnosine treatment in vivo in BTBR (Black and Tan, BRachyuric) ob/ob mice, a type 2 diabetes model which develops a phenotype that closely resembles advanced human DN. Treatment of BTBR ob/ob mice with 4 mM carnosine for 18 weeks reduced plasma glucose and HbA1c, concomitant with elevated insulin and C-peptide levels. Also, albuminuria and kidney weights were reduced in carnosine-treated mice, which showed less glomerular hypertrophy due to a decrease in the surface area of Bowman's capsule and space. Carnosine treatment restored the glomerular ultrastructure without affecting podocyte number, resulted in a modified molecular composition of the expanded mesangial matrix and led to the formation of carnosine-acrolein adducts. Our results demonstrate that treatment with carnosine improves glucose metabolism, albuminuria and pathology in BTBR ob/ob mice. Hence, carnosine could be a novel therapeutic strategy to treat patients with DN and/or be used to prevent DN in patients with diabetes.

Abstract
OBJECTIVE AND DESIGN Human amniotic epithelial cells (HAEC) resemble stem cells in their ability to differentiate into all three germ layers: endoderm, mesoderm, and ectoderm. Histamine receptors are expressed on HAEC. We examined the influence of histamine, and H(1) and H(2) antagonists on the generation of pancreatic islet beta-like cells from HAEC. MATERIALS AND METHODS HAEC were isolated after term pregnancies (N = 12) and cultured for 14 days with nicotinamide (10 mM) in normoxia. Altogether, 72 cultures were established. Histamine (100 microM) effects were investigated with mepyramine (10 microM) or cimetidine (10 microM). After 7 and 14 days, the mean concentration of C-peptide (MCCP) in the culture medium was measured immunoenzymatically as a marker of pancreatic differentiation. RESULTS MCCP was approximately threefold higher on day 14, compared to day 7. Histamine significantly increased MCCP, and more evident differences were observed after 7 days of culture than after 14 days. The mean percent increase +/-SEM in MCCP amounted to 142.19 +/- 21.7 and 79.03 +/- 12.35 compared to the controls on day 7 and 14, respectively. H(2) blockade significantly reduced histamine-related increase in MCCP, both on day 7 and 14 by 88.7 +/- 14.3 and 39.2 +/- 12.4%, respectively. H(1) receptor antagonist did not affect MCPP. CONCLUSION Nicotinamide-induced pancreatic differentiation of HAEC into beta-like cells may be augmented, probably at its earlier stage, by histamine acting via H(2) receptors.

Abstract
OBJECTIVE AND DESIGN Considering the role of histaminergic pathway in the differentiation of stem cells, we compared expression patterns of H(1) and H(2) receptors in the human amniotic epithelial cells (HAEC) culture at different stages of nicotinamide-induced differentiation into PBLC with the control HAEC. MATERIAL AND METHODS HAEC isolated after term pregnancies (N = 12) were cultured in vitro. Altogether, 72 cultures were established. The culture medium in the studied group was supplemented on Day 5 with nicotinamide (10 mM). C-peptide concentration in the medium collected every 3 days for 15 days was determined immunoenzymatically as a marker of differentiation. At the same intervals the cultures were formalin-fixed and paraffinembedded for H(1) and H(2) receptors immunostaining. Quantitative immunohistochemistry was applied for evaluation of H(1) and H(2) expression. RESULTS C-peptide was detected on Day 6 and the levels were kept gradually increased until Day 12, then stayed at almost the same level, 3.7-fold higher than initially. Expression of H(2) was unchanged until Day 9 after nicotinamide addition, then was significantly (p < 0.05) decreased and amounted (mean % value for the measurements performed on Day 12 and Day 15, +/-SEM) 49.73 +/- 11.03 of the reference value obtained in control HAEC. CONCLUSION Variable expression of H(2) during nicotinamide-induced differentiation of HAEC into PBLC may define a time-point, indicating involvement of histamine at the earlier stages.

Abstract
Histamine has been proposed to be an important regulator of energy intake and expenditure. The aim of this study was to evaluate histamine regulation of glucose and lipid metabolism and development of nonalcoholic steatohepatitis (NASH) with a hyperlipidemic diet. Histamine regulation of glucose and lipid metabolism, adipocytokine production, and development of hyperlipidemia-induced hepatic injury were studied in histamine H1 (H1R(-/-)) and H2 (H2R(-/-)) receptor knockout and wild-type mice. H1R(-/-) mice showed mildly increased insulin resistance. In contrast, H2R(-/-) mice manifested profound insulin resistance and glucose intolerance. High-fat/high-cholesterol feeding enhanced insulin resistance and glucose intolerance. Studies with two-deoxy-2-[(18)F]-fluoro-d-glucose and positron emission tomography showed a brain glucose allocation in H1R(-/-) mice. In addition, severe NASH with hypoadiponectinemia as well as hepatic triglyceride and free cholesterol accumulation and increased blood hepatic enzymes were observed in H2R(-/-) mice. H1R(-/-) mice showed an obese phenotype with visceral adiposity, hyperleptinemia, and less severe hepatic steatosis and inflammation with increased hepatic triglyceride. These data suggest that H1R and H2R signaling may regulate glucose and lipid metabolism and development of hyperlipidemia-induced NASH.

Abstract
Histidine decarboxylase (HDC) and vesicular monoamine transporter 2 (v-MAT2) are involved in the biosynthesis and storage of histamine. DOPA decarboxylase (DDC) is involved in the biosynthesis of a variety of amines and shares a high degree of homology with HDC. HDC and v-MAT2 immunoreactivities (IR) have recently been detected in well-differentiated neuroendocrine tumors (WDNETs) and poorly differentiated neuroendocrine carcinomas (PDNECs) of various sites and have been proposed as general endocrine markers. We evaluated HDC and v-MAT2 IR in a series of 117 WDNETs and PDNECs from different sites. Western blotting analysis was performed to verify the specificity of anti-DDC and anti-HDC antibodies. Real-time RT-PCR was performed using specific probes for HDC and DDC on 42 cases, examined also for DDC IR. HDC and v-MAT2 IR were observed in the majority of WDNETs and PDNECs of all sites and HDC-IR cases were always also DDC-IR. In contrast, high levels of HDC mRNA were detected only in the gastroenteropancreatic WDNETs, which did not show increased DDC mRNA levels. On the other hand, bronchial carcinoids and lung PDNECs showed high DDC mRNA levels, but nearly undetectable HDC mRNA levels. Western blotting analysis showed a cross-reaction between anti-HDC and anti-DDC antibodies. HDC should not be considered as a general endocrine marker and HDC IR in bronchial carcinoids and PDNECs of the lung can probably be attributed to a cross-reaction with DDC.

Abstract
Histidine decarboxylase (HDC) is an enzyme for decarboxylating l-histidine to histamine and is expressed in various types of cells including neuroendocrine tumors. Recent findings have demonstrated a high percentage of HDC immunoreactivity in many neuroendocrine tumors, including carcinoid tumors, small cell carcinomas of the lung, pheochromocytomas, and medullary carcinomas of the thyroid. HDC immunostaining was applied to pancreatic islet cells and related tumors to explore possible expression of HDC as a wide spectrum marker for neuroendocrine differentiation. A total of 24 cases (22 pancreatic endocrine neoplasms, one small cell carcinoma of the pancreas, and one mixed exocrine-endocrine carcinoma) along with normal pancreatic tissue were immunostained with the anti-HDC antibody. In a normal pancreas, a double immunostaining revealed possible colocalization of HDC with glucagon- or insulin-positive cells in the islets. Seventeen of 22 pancreatic endocrine neoplasms (77%) were found to be positive for HDC, and no distinct relation to hormonal activity was observed. One small cell carcinoma was strongly positive to HDC. One non-functional tumor with mixed exocrine and endocrine components showed a diffuse positive immunostaining for HDC, and some neoplastic glucagon- or somatostatin (SRIF)-positive cells coexpressed HDC. In conclusion, we demonstrated that the majority of pancreatic endocrine tumors expressed HDC, and we suggest that HDC is a wider new marker for neuroendocrine differentiation.

Abstract
The uptake of monoamines into the secretory granules of monoamine-storing neuroendocrine cells is mediated by vesicular monoamine transporter protein 1 or 2 (VMAT1 or VMAT2). This study analyzed the expression of VMAT1 and VMAT2 in endocrine cells of normal human and monkey pancreas. The expression of VMAT1 and VMAT2 was also examined in infants with hyperinsulinemic hypoglycemia and in adults with pancreatic endocrine tumors (PETs). Using immunohistochemistry (IHC) and in situ hybridization (ISH), we demonstrated the mutually exclusive expression of VMAT1 in endocrine cells of the duct system and of VMAT2 in many cells of the islets of Langerhans. By confocal laser scanning microscopy, VMAT1-positive cells were identified as enterochromaffin (EC) cells and VMAT2-positive cells as beta-cells. In PETs, VMAT1 was found exclusively in all serotonin-containing tumors. In contrast, VMAT2 expression was lost in many insulinomas, independent of their biological behavior. VMAT2 was expressed by some non-insulin-producing tumors. The mutually exclusive expression of VMAT1 in EC cells and of VMAT2 in beta-cells suggests that both cell types store monoamines. Monoamine storage mediated by VMAT1 in EC cells is apparently maintained in EC cell tumors. In contrast, many insulinomas appear to lose their ability to accumulate monoamines via VMAT2.
