Abstract
Aims To evaluate the correlation of nesfatin-1, GSH and SOD levels with β-cell insulin secretion and their influence on insulin secretion in the development of type 2 diabetes mellitus (T2DM). Materials and methods 75 patients with T2DM, 67 with prediabetes and 37 heathy participants were recruited in this study. Serum levels of nesfatin-1, GSH and SOD were quantified and statistically analyzed. Results The levels of nesfatin-1, GSH and SOD in T2DM were significantly decreased (P < 0.001) compared to either in prediabetes or in healthy control, and significant reduction of these biomarkers was also observed in prediabetes when compared to the control (P < 0.001). Circulating nesfatin-1, GSH and SOD were not only strongly correlated with β-cell insulin secretion, but also exerted remarkable influence on the secretion. Conclusion Serum nesfatin-1, GSH and SOD are important factors involving insulin secretion in the development of T2DM, which may help provide new ideas for forthcoming investigations on the roles of these factors in pathogenesis of T2DM, as well as for active prediction and prevention of prediabetes before it develops into overt T2DM.

Hypothalamic Nesfatin-1 Resistance May Underlie the Development of Type 2 Diabetes Mellitus in Maternally Undernourished Non-obese Rats. Front Neurosci 2022; 16:828571. [PMID: 35386592 PMCID: PMC8978526 DOI: 10.3389/fnins.2022.828571] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Accepted: 02/08/2022] [Indexed: 11/13/2022] Open
Abstract
Intrauterine growth retardation (IUGR) poses a high risk for developing late-onset, non-obese type 2 diabetes (T2DM). The exact mechanism underlying this phenomenon is unknown, although the contribution of the central nervous system is recognized. The main hypothalamic nuclei involved in the homeostatic regulation express nesfatin-1, an anorexigenic neuropeptide and identified regulator of blood glucose level. Using intrauterine protein restricted rat model (PR) of IUGR, we investigated, whether IUGR alters the function of nesfatin-1. We show that PR rats develop fat preference and impaired glucose homeostasis by adulthood, while the body composition and caloric intake of normal nourished (NN) and PR rats are similar. Plasma nesfatin-1 levels are unaffected by IUGR in both neonates and adults, but pro-nesfatin-1 mRNA expression is upregulated in the hypothalamus of adult PR animals. We find that centrally injected nesfatin-1 inhibits the fasting induced neuronal activation in the hypothalamic arcuate nucleus in adult NN rats. This effect of nesfatin-1 is not seen in PR rats. The anorexigenic effect of centrally injected nesfatin-1 is also reduced in adult PR rats. Moreover, chronic central nesfatin-1 administration improves the glucose tolerance and insulin sensitivity in NN rats but not in PR animals. Birth dating of nesfatin-1 cells by bromodeoxyuridine (BrDU) reveals that formation of nesfatin-1 cells in the hypothalamus of PR rats is disturbed. Our results suggest that adult PR rats acquire hypothalamic nesfatin-1-resistance, probably due to the altered development of the hypothalamic nesfatin-1 cells. Hypothalamic nesfatin-1-resistance, in turn, may contribute to the development of non-obese type T2DM.

Abstract
Nesfatin-1 is a hypothalamic anorexigenic peptide processed from nucleobindin 2 (NUCB2). Central and peripheral administration of NUCB2/nesfatin-1 enhances glucose metabolism and insulin release. NUCB2/nesfatin-1 is also localized in pancreatic islets, while its function remains unknown. To explore the role of pancreatic β-cell-produced NUCB2/nesfatin-1, we developed pancreatic β-cell-specific NUCB2 knockout (βNUCB2 KO) mice and NUCB2 gene knockdown (shNUCB2) MIN6 β-cell line. In βNUCB2 KO mice, casual blood glucose was elevated from 12 weeks of age. In a glucose tolerance test at 12 weeks, insulin secretion at 15 min was reduced and blood glucose at 2 h increased in βNUCB2 KO mice fasted 8 h. In islets isolated from βNUCB2 KO mice, high glucose-stimulated insulin secretion (GSIS) was impaired. In shNUCB2 MIN6 cells, GSIS was reduced and UCP-2 mRNA expression was elevated. These results show impaired GSIS possibly associated with UCP-2 overexpression in NUCB2-silenced β-cells, suggesting that β-cell-produced NUCB2/nesfatin-1 maintains GSIS and thereby glycemia.

Abstract
The role of nesfatin-1 in glucose homeostasis has been investigated previously. However, although numerous studies have examined the relationships between circulating nesfatin-1 levels and type 2 diabetes, the conclusions are contradictory. We aimed to probe the relationship between circulating nesfatin-1 levels and type 2 diabetes by meta-analysis. Seven studies including 328 type 2 diabetes patients and 294 control subjects were included. Although there was no obvious difference in circulating nesfatin-1 levels between patients with type 2 diabetes and the control group (MD = -0.04; 95% CI = -0.32 to -0.23), subgroup analysis showed higher nesfatin-1 levels in newly diagnosed type 2 diabetes patients (MD = 0.59; 95% CI = 0.45 to 0.74) and significantly lower nesfatin-1 levels in type 2 diabetes patients receiving antidiabetic treatment (MD = -0.26; 95% CI = -0.33 to -0.20). In conclusion, the analysis supports a relationship between circulating nesfatin-1 levels and type 2 diabetes, where newly diagnosed type 2 diabetes was associated with an elevated Nesfatin-1 level, and type 2 diabetes patients receiving antidiabetic treatment showed lower circulating nesfatin-1 levels.

[PMID: 26950482 PMCID: PMC4817075 DOI: 10.1038/nutd.2015.42] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2015] [Revised: 10/26/2015] [Accepted: 11/15/2015] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Nesfatin/Nucleobindin-2 (Nesf/NUCB2), a precursor of nesfatin-1, an anorexigenic protein, is ubiquitously expressed in peripheral tissues in addition to the hypothalamus. However, the role of intracellular Nesf/NUCB2 has not been established in the periphery. METHODS Nesf/NUCB2-transgenic (Tg) mice were generated, and chronological changes of body weight and daily food intake were measured in Nesf/NUCB2-Tg mice fed normal laboratory chow or 45% high-fat diet (HFD). In addition, changes of metabolic markers were evaluated in those mice. RESULTS No differences were observed in daily food intake and body weight between Nesf/NUCB2-Tg mice (n=11) and their non-Tg littermates (n=11) fed normal chow. Nesf/NUCB2-Tg mice showed increased mRNA expression of oxytocin and corticotropin-releasing hormone and decreased mRNA expression of cocaine- and amphetamine-related transcript in the hypothalamus. Nesf/NUCB2-Tg mice fed 45% HFD (n=6) showed significantly higher increase in body weight than their non-Tg littermates fed the same diet (n=8); however, no difference was observed in daily food intake between these two groups. Further, Nesf/NUCB2-Tg mice fed 45% HFD showed a significant increase in the weight of the liver, subcutaneous fat, and brown adipose tissue and decrease in the expression of uncoupling protein-1 in the subcutaneous fat. Blood glucose levels of Nesf/NUCB2-Tg mice fed 45% HFD were not different from those of their non-Tg littermates fed the same diet. Insulin levels of these Tg mice were significantly higher than those of their non-Tg littermates. Histological analysis showed marked fat deposition in the hepatocytes surrounding the hepatic central veins in Nesf/NUCB2-Tg mice fed 45% HFD. CONCLUSIONS Overexpression of Nesf/NUCB2 did not change food intake, but increased body weight only in Nesf/NUCB2-Tg mice fed HFD. The results of this study indicate that Nesf/NUCB2 was involved in the development of insulin resistance and fat deposition in the liver, independent of the modulation of energy intake.
