Abstract Background: Type 2 diabetes (T2DM) is a top risk factor for health in China. Gut microbiota, genetic factors and lipids metabolism play important role in development of T2DM. In this study, we investigated the relationship between the gut microbiota and omentin-1 gene polymorphism to explore the interaction between host gene and gut microbiota in Uyghur T2DM. Methods: A total of 98 newly diagnosed Uyghur T2DM patients and 99 healthy normal controls (NC) enrolled into this study according to inclusion criteria. The total DNAs was extracted from the fecal microbiota. Abundance of the Lactobacillus genus, Bacteroides thetaiotaomicron and Clostridium in the gut microbiota was determined with 16S rDNA gene Real-time fluorescence quantitative PCR amplification. PCR-PFLP was applied to determine the genotypes of Val109Asp variant (rs2274907) in the Omentin-1 gene. And the relationship between rs2274907 and gut microbiota was assessed. Results: There were no significant differences of the Val109Asp variant (rs2274907) between T2DM and NC group. The abundance of Lactobacillus genus and Clostridium genus was lower in newly diagnosed T2DM group than in the NC group (P<0.05). Serum insulin, LDL-C, the abundances of Lactobacillus genus and Clostridium genus were the risk factors of T2DM. (OR=1.094 95%CI 1.014-1.180), (OR=3.868 95%CI 1.250-11.971), (OR=0.288 95%CI 0.145-0.571), (OR=0.044 95%CI 0.012-0.154). Conclusions: The abundance of Lactobacillus and Clostridium genus may be related to the pathogenesis of new-onset T2DM in Uyghur population, the mechanism of which needs to be further studied. The interactive relationship between the gut microbiota and omentin-1 gene polymorphism in newly diagnosed T2DM was not observed in this study.

AbstractGut microbiota and its metabolites have been shown to influence multiple physiological mechanisms related to human health. Among microbial metabolites, short-chain fatty acids (SCFA) are modulators of different metabolic pathways. On the other hand, several studies suggested that diet might influence gut microbiota composition and activity thus modulating the risk of metabolic disease, i.e. obesity, insulin resistance and type 2 diabetes. Among dietary component, dietary fibre may play a pivotal role by virtue of its prebiotic effect on fibre-fermenting bacteria, that may increase SCFA production. The aim of this review was to summarize and discuss current knowledge on the impact of dietary fibre as modulator of the relationship between glucose metabolism and microbiota composition in humans. More specifically, we analysed evidence from observational studies and randomized nutritional intervention investigating the relationship between gut microbiota, short-chain fatty acids and glucose metabolism. The possible mechanisms behind this association were also discussed.

The aim of this study was to investigate the relationship between serum 25-hydroxy vitamin D (25-OHD) and insulin sensitivity andβ-cell function in newly diagnosed type 2 diabetes. 395 newly diagnosed type 2 diabetes patients were enrolled in this study. Venous blood samples were collected at 0 min, 30 min, and 120 min of OGTT to measure serum glucose and insulin. Matsuda ISI and HOMA-IR were used to determine insulin sensitivity. The ratio of 0–120 min area under curve of insulin to glucose (insulin release index, INSR) was calculated as surrogate index ofβ-cell insulin secretion function. The products of insulin secretion indices multiplied by Matsuda insulin sensitivity index were used as disposition indices. Patients were divided into three groups according to tertiles (T1, T2, and T3) of 25-OHD concentration. There was significant difference among three groups for HOMA-IR, Matsuda ISI, and INSR. HOMA-IR, Matsuda ISI, INSR, and DI were undifferentiated among three groups in male patients. But HOMA-IR, Matsuda ISI, and INSR were significantly different among three groups in female patients after being adjusted by confounding factors. In conclusion, serum 25-OHD is associated with insulin sensitivity andβ-cell function for female newly diagnosed type 2 diabetes patients, and the association is ambiguous in males.

Type 2 diabetes mellitus (T2DM) remains one of the most problematic and economic consumer disorders worldwide, with growing prevalence and incidence. Over the last years, substantial research has highlighted the intricate relationship among gut microbiota, dysbiosis and metabolic syndromes development. Changes in the gut microbiome composition lead to an imbalanced gastrointestinal habitat which promotes abnormal production of metabolites, inflammatory status, glucose metabolism alteration and even insulin resistance (IR). Short-chain fatty acids (SCFAs), trimethylamine N-oxide (TMAO), lipopolysaccharide, aromatic amino acids and their affiliated metabolites, contribute to T2DM via different metabolic and immunologic pathways. In this narrative review, we discuss the immunopathogenic mechanism behind gut dysbiosis, T2DM development and the major known diabetic microvascular complications (retinopathy, neuropathy and nephropathy), the beneficial use of pre- and pro-biotics and fecal microbiota transplantation in T2DM management and new findings and future perspectives in this field.

Introduction: Non-alcoholic fatty liver disease (NAFLD) remains an important health issue worldwide. The increasing prevalence of NAFLD is linked to type 2 diabetes (T2D). The gut microbiota is associated with the development of NAFLD and T2D. However, the relationship between gut microbiota and NAFLD severity has remained unclear in T2D patients. The aim of this study was to evaluate the relationship of gut microbiota with the severity of NAFLD in T2D patients. Methods: This cross-sectional study used transient elastography (FibroScan) to evaluate the severity of hepatic steatosis. We utilized qPCR to measure the abundance of Bacteroidetes, Firmicutes, Faecalibacterium prausnitzii, Clostridium leptum group, Bacteroides, Bifidobacterium, Akkermansia muciniphila, and Escherichia coli. Results: Of 163 T2D patients, 83 with moderate to severe NAFLD had higher abundance of bacteria of the phylum Firmicutes with respect to 80 patients without NAFLD or with mild NAFLD. High abundance of the phylum Firmicutes increased the severity of NAFLD in T2D patients. A positive correlation between NAFLD severity and the phylum Firmicutes was found in T2D male patients with body mass index ≥24 kg/m2 and glycated hemoglobin <7.5%. Conclusion: Enrichment of the fecal microbiota with the phylum Firmicutes is significantly and positively associated with NAFLD severity in T2D patients. The gut microbiota is a potential predictor of NAFLD severity in T2D patients.

Abstract Background: Several studies have shown the association of polymorphisms in the MTNR1B gene with type 2 diabetes mellitus (T2DM). However, there is no evidence about the impacts of its genetic polymorphism on the therapeutic efficacy of nateglinide. Therefore, this prospective case-control study was designed to investigate the effect of MTNR1B rs10830963 gene polymorphism on the therapeutic efficacy of nateglinide in treating T2DM. Methods: We genotyped 200 healthy subjects using the method of the high resolution of melting curve (HRM). A total of 60 newly diagnosed T2DM patients were enrolled and given nateglinide (360 mg/d) for 8 weeks orally who had the same genotypes CYP2C9*1 and SLCO1B1 521TT respectively. The outcome was measured by collecting the venous blood samples before and at the 8th week of the treatment. Also, anthropometric measurements, glucose, and lipid metabolism were determined before and after the nateglinide treatment. Result: It was found that the risk G allelic frequency of MTNR1B rs10830963 was higher in T2DM patients when compared with the healthy subjects (P<0.05). A total of 60 newly diagnosed patients with type 2 diabetes after completing the eight weeks treatment came for the follow-up visit and showed a less reduction in fasting plasma glucose (FPG) levels with a less increase in homeostasis model assessment for β cell HOMA-β in the carriers of G allele at rs10830963, when compared with the wild-type CC (P <0.05). Conclusion: Thus, it was found that the MTNR1B rs10830963 polymorphism was associated with the therapeutic efficacy of nateglinide in T2DM patients. Also, the CC homozygotes had a better effect than G allele carriers.

Underlying Mechanisms

Gut microbiota has attracted widespread attention due to its crucial role in disease pathophysiology, including type 2 diabetes mellitus (T2DM). Metabolites and bacterial components of gut microbiota affect the initiation and progression of T2DM by regulating inflammation, immunity, and metabolism. Short-chain fatty acids, secondary bile acid, imidazole propionate, branched-chain amino acids, and lipopolysaccharide are the main molecules related to T2DM. Many studies have investigated the role of gut microbiota in T2DM, particularly those butyrate-producing bacteria. Increasing evidence has demonstrated that fecal microbiota transplantation and probiotic capsules are useful strategies in preventing diabetes. In this review, we aim to elucidate the complex association between gut microbiota and T2DM inflammation, metabolism, and immune disorders, the underlying mechanisms, and translational applications of gut microbiota. This review will provide novel insight into developing individualized therapy for T2DM patients based on gut microbiota immunometabolism.
