DNA Methylation Profiling Reveals Novel Pathway Implicated in Cardiovascular Diseases of Diabetes

Project description:Epigenetics was reported to mediate the effects of environmental risk factors on disease pathogenesis. To unleash the role of DNA methylation modification in the pathological process of cardiovascular diseases in diabetes, we screened differentially methylated genes by methylated DNA immunoprecipitation chip (MeDIP-chip) among the enrolled participants.

DNA methylation profiling reveals novel pathway implicated in cardiovascular diseases of diabetes.

Project description:ObjectiveEpigenetics was reported to mediate the effects of environmental risk factors on disease pathogenesis. We intend to unleash the role of DNA methylation modification in the pathological process of cardiovascular diseases in diabetes.MethodsWe screened differentially methylated genes by methylated DNA immunoprecipitation chip (MeDIP-chip) among the enrolled participants. In addition, methylation-specific PCR (MSP) and gene expression validation in peripheral blood of participants were utilized to validate the DNA microarray findings.ResultsSeveral aberrantly methylated genes have been explored, including phospholipase C beta 1 (PLCB1), cam kinase I delta (CAMK1D), and dopamine receptor D5 (DRD5), which participated in the calcium signaling pathway. Meanwhile, vascular endothelial growth factor B (VEGFB), placental growth factor (PLGF), fatty acid transport protein 3 (FATP3), coagulation factor II, thrombin receptor (F2R), and fatty acid transport protein 4 (FATP4) which participated in vascular endothelial growth factor receptor (VEGFR) signaling pathway were also found. After MSP and gene expression validation in peripheral blood of participants, PLCB1, PLGF, FATP4, and VEGFB were corroborated.ConclusionThis study revealed that the hypomethylation of VEGFB, PLGF, PLCB1, and FATP4 might be the potential biomarkers. Besides, VEGFR signaling pathway regulated by DNA methylation might play a role in the cardiovascular diseases' pathogenesis of diabetes.

Liver proteomics of the HMDP - Hepatosteatosis underlies several diseases including type 2 diabetes, cardiovascular disease and liver disease

Project description:Hepatosteatosis underlies several diseases including type 2 diabetes, cardiovascular disease and liver disease. Unfortunately, our understanding of the contributing pathways that initiate and advance hepatosteatosis to subsequent complications is still poorly understood. Here, we take advantage of recent developments in “omics” technologies to perform high resolution proteomics (>5000 proteins) and quantitative lipidomics (>300 lipids) on livers from 107 genetically diverse inbred mouse strains from the hybrid mouse diversity panel. Integration of these data allowed us to define novel regulators of lipid metabolism in the liver.

Omics Profiling of Patients with Obstructive Sleep Apnoea Reveals Risks of Diabetes Mellitus and Cardiovascular Diseases

Project description:Obstructive sleep apnoea (OSA), a type of chronic intermittent hypoxia with increasing global prevalence, constitutes a multisystemic disorder often associated with cardiovascular and metabolic disorders.In total, 142 plasma samples were acquired: 50 from controls (CON), 45 from mild/moderate OSA (M-OSA) patients, and 47 from severe OSA (S-OSA) patients.Proteomic and metabolic signatures significantly differed among S-OSA, M-OSA, and CON samples.Omics analysis revealed the characteristics of OSA and uncovered potential mechanisms by which diabetes mellitus and cardiovascular disease risks are increased in OSA. These results might also provide new diagnostic biomarkers for OSA and the identification of severe cases.

Changes of Muramyl Dipeptide in Intestinal and Extra-intestinal Diseases

Project description:Nucleotide-binding oligomerization domain 2 (Nod2) signaling is critical for human health.To figure out the clinical relevance of NOD2 ligands, the investigators plan to evaluate the change of NOD2 ligands in inflammatory bowel diseases (IBD), CRC, atherosclerotic cardiovascular disease (ACVD), and type 2 diabetes mellitus (DM2 ).
