Aim

To characterize the urinary metabolomic fingerprint and multi-metabolite signature associated with type 2 diabetes (T2D), and to classify the population into metabotypes related to T2D.

Methods

A metabolomics analysis using the 1H-NMR-based, non-targeted metabolomic approach was conducted to determine the urinary metabolomic fingerprint of T2D compared with non-T2D participants in the PREDIMED trial. The discriminant metabolite fingerprint was subjected to logistic regression analysis and ROC analyses to establish and to assess the multi-metabolite signature of T2D prevalence, respectively. Metabotypes associated with T2D were identified using the k-means algorithm.

Results

A total of 33 metabolites were significantly different (P < 0.05) between T2D and non-T2D participants. The multi-metabolite signature of T2D comprised high levels of methylsuccinate, alanine, dimethylglycine and guanidoacetate, and reduced levels of glutamine, methylguanidine, 3-hydroxymandelate and hippurate, and had a 96.4% AUC, which was higher than the metabolites on their own and glucose. Amino-acid and carbohydrate metabolism were the main metabolic alterations in T2D, and various metabotypes were identified in the studied population. Among T2D participants, those with a metabotype of higher levels of phenylalanine, phenylacetylglutamine, p-cresol and acetoacetate had significantly higher levels of plasma glucose.

Conclusion

The multi-metabolite signature of T2D highlights the altered metabolic fingerprint associated mainly with amino-acid, carbohydrate and microbiota metabolism. Metabotypes identified in this patient population could be related to higher risk of long-term cardiovascular events and therefore require further studies. Metabolomics is a useful tool for elucidating the metabolic complexity and interindividual variation in T2D towards the development of stratified precision nutrition and medicine.Trial registration at www.controlled-trials.com: ISRCTN35739639.  相似文献

Background: It is well-established that differences among ethnic groups in drug responses are primarily due to the genetic diversity of pharmacogenes. A number of genes or variants that play a crucial role in drug responses have been designated Very Important Pharmacogenes (VIP) by the PharmGKB database. Clarifying the polymorphic distribution of VIPs in different ethnic groups will aid in personalized medicine for specific populations. Methods: We sequenced 85 VIP variants in the Lhoba population based on the PharmGKB database. The polymorphic distribution of the 85 VIP variants in 100 Lhoba subjects was determined and compared with that of 11 major HapMap populations, including ASW, CEU, CHB, CHD, GIH, JPT, LWK, MEX, MKK, TSI, and YRI. We used χ2 tests to identify significantly different loci between these populations. We downloaded SNP allele frequencies from the ALlele FREquency Database to observe the global genetic variation distribution for these specific loci. And then we used Structure software to perform the genetic structure analysis of 12 populations. Results: Based on comparisons of selected available loci, we found that 23, 28, 16, 10, 20, 16, 24, 19, 22, 21 and 36 of the selected VIP variant genotype frequencies in the Lhoba population differed from those of the ASW, CEU, CHB, CHD, GIH, JPT, LWK, MEX, MKK, TSI, and YRI populations, respectively. In addition, Pairwise FST values and clustering analyses also showed the VIP variants in Lhoba exhibited a close genetic affinity with CHD, CHB and JPT populations. Conclusion: Our results complement pharmacogenomic data on the Lhoba ethnic group and may be helpful in the diagnosis of certain diseases in minorities.  相似文献

In the turkey, exogenous serotonin (5-hydroxytryptamine, 5-HT) increases prolactin (PRL) secretion by acting through the dopaminergic (DAergic) system. In the present study, infusion of the 5-HT2C receptor agonist, (R)(−)-DOI hydrochloride (DOI), into the third ventricle stimulates PRL secretion, whereas the 5-HT1A receptor agonist, (+/−)-8-OH-DPAT hydrobromide (DPAT), inhibits PRL secretion. Using the immediate-early gene, c-fos, as an indicator of neuronal activity, in situ hybridization histochemistry showed preferential c-fos co-localization within tyrosine hydroxylase immunoreactive neurons (the rate limiting enzyme in DA synthesis) in the areas of the nucleus preopticus medialis (POM) and the nucleus premammillaris (PMM), in response to DPAT and DOI, respectively. To clarify the involvement of 5-HT1A and 5-HT2C receptors in PRL regulation, their mRNA expression was determined on hypothalamic tissue sections from birds in different reproductive stages. A significant difference in 5-HT1A receptor was observed, with the POM of hypoprolactinemic short day and photorefractory birds showing the highest expression. 5-HT2C receptors mRNA did not change during the reproductive cycle. The data presented support the notion that DA neurons in the PMM and POM mediate the stimulatory and inhibitory effects of 5-HT, respectively, on PRL secretion and the 5-HTergic system can both stimulate and inhibit PRL secretion.  相似文献

Virtually every eukaryotic cell has an endogenous circadian clock and a biological sex. These cell-based clocks have been conceptualized as oscillators whose phase can be reset by internal signals such as hormones, and external cues such as light. The present review highlights the inter-relationship between circadian clocks and sex differences. In mammals, the suprachiasmatic nucleus (SCN) serves as a master clock synchronizing the phase of clocks throughout the body. Gonadal steroid receptors are expressed in almost every site that receives direct SCN input. Here we review sex differences in the circadian timing system in the hypothalamic–pituitary–gonadal axis (HPG), the hypothalamic–adrenal–pituitary (HPA) axis, and sleep–arousal systems. We also point to ways in which disruption of circadian rhythms within these systems differs in the sexes and is associated with dysfunction and disease. Understanding sex differentiated circadian timing systems can lead to improved treatment strategies for these conditions.  相似文献

目的:观察基于"脑-肠轴"学说组方的清开通灌肠液,对内毒素性发热兔的退热效应及VIP、IL-2在发热中的变化。方法:日本大耳白家兔60只,随机分成4组:正常组、模型组、清开灵组和清开通组。模型组、清开灵组及清开通组,各组经耳缘静脉注射无热源生理盐水稀释的内毒素,建立兔内毒素性发热模型。同时清开灵组、清开通组分别予以清开灵、清开通灌肠液灌肠。注射内毒素2h后,清开灵组、清开通组再予灌肠1次。4h后,各组动物随机抽取10只,采集脑、肠及外周血标本,用放射免疫法检测脑、肠及血浆中VIP、IL-2含量。持续观察每组另外5只动物体温变化情况,每间隔10min记录1次体温,连续测温12h。结果:清开灵组和清开通组动物的体温与模型组相比都有明显降低(P0.01),但清开通组降低比清开灵组更为显著(P0.05)。脑肠及血浆中VIP和IL-2的含量都显著低于模型组(P0.01),尤其清开通组较清开灵组降低幅度更大,二者有显著差异(P0.05)。结论:"清开"与"通腑"合治,较单一清开法在退热及提高机体免疫方面效果更著,VIP和IL-2在发热中起正调节作用。  相似文献
