Transcriptional profiling of diabetic peripheral neuropathy patients, diabetic patients, and healthy participants

ABSTRACT: Diabetic peripheral neuropathy (DPN) is a common complication of diabetes mellitus (DM). It is not diagnosed or managed properly in the majority of patients, because its pathogenesis remains controversial. In this study, using microarray-based genome-wide expression analyses, we sought to identify both common and distinct mechanisms underlying the pathogenesis of DM and DPN. The results demonstrated that down-regulation of the neurotrophin-MAPK signaling pathway may be the major mechanism of DPN pathogenesis, thus providing a potential approach for DPN treatment.

Analysis of altered miRNA expression profiles in the streptozotocin-induced diabetic rats compared to normal SD rats

Project description:Diabetes mellitus (DM) is one of the most common chronic diseases around the world, and diabetic peripheral neuropathy (DPN) is one of the most common complications of DM. We used microarrays to identify the differentially expressed miRNAs in dorsal root ganglia (DRG) tissues from streptozotocin (STZ)-induced diabetic rats, taking normal SD rats as controls, and tried to find out the related genes which may be involved in the development of DPN.

The expression of mRNA and lncRNA in peripheral blood mononuclear cells (PBMCs) of diabetes mellitus, diabetic retinopathy (DR), diabetic peripheral neuropathy (DPN) and diabetic nephropathy (DN) patients

Project description:DR, DPN and DN are common complications in diabetes, and the differentially expressed mRNAs and lncRNAs in these diabetic complications may help to identify the molecular markers for the onset and progression of diseases. In our study, high-throughput sequencing technique was used to analyze the expression profile of mRNA and lncRNA in the peripheral blood of health control, T2DM, DR, DPN and DN patients, in order to determine the differentially expressed transcriptomic profiles changes in diabetic complications and identify the shared and specific biological signaling pathways related to DR, DPN and DN.

Gene expression profiles of diabetic kidney disease and neuropathy in eNOS knockout mice: predictors of pathology and RAAS blockade effects

Project description:Diabetic kidney disease (DKD) and diabetic peripheral neuropathy (DPN) are two common diabetic complications. However, their pathogenesis remains elusive and current therapies are only modestly effective. We evaluated genome-wide expression to identify pathways involved in DKD and DPN progression in db/db eNOS -/- mice receiving renin-angiotensin-aldosterone system (RAAS) blocking drugs to mimic the current standard of care for DKD patients. Diabetes and eNOS deletion worsened DKD, which improved with RAAS treatment. Diabetes also induced DPN, which was not affected by eNOS deletion or RAAS blockade. Given the multiple factors affecting DKD and the graded differences in disease severity across mouse groups, an automatic data-analysis method, SOM or self-organizing map was used to elucidate glomerular transcriptional changes associated with DKD, whereas pairwise bioinformatics analysis was used for DPN. These analyses revealed that enhanced gene expression in several pro-inflammatory networks and reduced expression of development genes correlated with worsening DKD. Although RAAS treatment ameliorated the nephropathy phenotype, it did not alter the more abnormal gene expression changes in kidney. Moreover, RAAS exacerbated expression of genes related to inflammation and oxidant generation in peripheral nerves. The graded increase in inflammatory gene expression and decrease in development gene expression with DKD progression underline the potentially important role of these pathways in DKD pathogenesis. Since RAAS blockers worsened this gene expression pattern in both DKD and DPN, it may partly explain the inadequate therapeutic efficacy of such blockers.

Sarm1 knockout prevents type 1 diabetic bone disease in females independent of neuropathy

Project description:Diabetic patients have a high risk of developing skeletal diseases accompanied by diabetic peripheral neuropathy (DPN). In this study, we isolated the role of DPN in skeletal disease with global and conditional knockout models of sterile-α and TIR-motif-containing protein-1 (Sarm1). SARM1, an NADase highly expressed in the nervous system, regulates axon degeneration upon a range of insults, including DPN. Global knockout of Sarm1 prevented DPN, but not skeletal disease, in male mice with type 1 diabetes (T1D). Female wild type mice also developed diabetic bone disease, but without DPN. Unexpectedly, global Sarm1 knockout completely protected female mice from T1D-associated bone suppression and skeletal fragility despite comparable muscle atrophy and hyperglycemia. Global Sarm1 knockout rescued bone health through sustained osteoblast function with abrogation of local oxidative stress responses. This was independent of the neural actions of SARM1, as beneficial effects on bone were lost with neural conditional Sarm1 knockout. This study demonstrates that the onset of skeletal disease occurs rapidly in both male and female mice with T1D completely independent of DPN. In addition, this reveals that clinical SARM1 inhibitors, currently being developed for treatment of neuropathy, may also have benefits for diabetic bone through actions outside of the nervous system.

Skeletal muscle regeneration is compromised in advanced diabetic peripheral neuropathy

Project description:DPN muscle exhibits features of degeneration with attempted regeneration. In the most severely pathological muscle samples, regeneration appears to be stymied and our data suggest that this may be partly due to intrinsic dysfunction of the satellite cell pool in addition to extrinsic structural pathology (e.g. nerve damage).

Comparative RNA-Seq transcriptome analyses of diabetic nerve and kidney disease II

Project description:Diabetic kidney disease (DKD) and diabetic peripheral neuropathy (DPN) are common complications of type 1 (T1D) and type 2 (T2D) diabetes. However, the mechanisms underlying the development and progression of these complications are unclear. Thus, the goal of the current study was to use system biology approaches to examine DKD and DPN pathogenesis in T1D and T2D mouse models on the same genetic background. We optimized a streptozotocin-induced db/+ murine model of T1D and compared it to our established db/db T2D mouse model of the same C57BLKS/J background and confirmed both develop DKD and DPN. Transcriptomic data from glomeruli and sciatic nerve tissue from T1D and T2D mice were analyzed by self-organizing map and differential gene expression analysis followed by functional enrichment. Consistent with prior literature, pathways related to immune function and inflammation were dysregulated in both DKD and DPN in T1D and T2D mice. The gene-level analysis identified a high degree of concordance in DEGs in both DKD and DPN and across diabetes type, suggesting genetic background influences diabetic complications. These findings offer new insight as the influence of genetic background on DPN in mouse models has not been well defined. Collectively, these findings support the role of inflammation and genetic background in complications of both T1D and T2D.

Dorsal root ganglia (DRG) and Sciatic nerve (SCN) in female BTBR ob/ob mice - diabetic peripheral neuropathy

Project description:Female mouse models of diabetic peripheral neuropathy (DPN) have not yet been identified. Our aim is firstly to demonstrate that female BTBR ob/ob mice display robust DPN and secondly, to perform relevant comparisons with non-diabetic and gender-matched controls. Lastly, microarray technology was employed to identify dysregulated genes and pathways in the SCN and DRG of female BTBR mice. Dorsal root ganglia (DRG) and sciatic nerve (SCN) were removed from female mice, RNA isolated and processed for gene expression profiling to identify differentially expressed genes using Affymetrix GeneChip Mouse Genome 430 2.0 Arrays.
