Proteomic exploration of common pathophysiological pathways in diabetes and cardiovascular disease.

ABSTRACT:

Aims

The epidemiological association between diabetes and cardiovascular disease is well established, but the pathophysiological link is complex and multifactorial. We investigated seven proteins, previously linked to incident diabetes mellitus, and their association with cardiovascular disease and mortality.

Methods and results

Plasma samples from 1713 individuals from the Swedish population-based Malmö Preventive Project (mean age 67.4 ± 6.0 years; 29.1% women) were analysed with a proximity extension assay panel. Seven proteins [scavenger receptor cysteine rich type 1 protein M130 (CD163), fatty acid-binding protein 4 (FABP4), plasminogen activator inhibitor 1 (PAI), insulin-like growth factor-binding protein 2 (IGFB2), cathepsin D (CTSD), galectin-4 (GAL4), and paraoxonase-3 (PON3)] previously shown to be associated with incident diabetes were analysed for associations with all-cause mortality (ACM), cardiovascular mortality (CVM), incident coronary events (CEs), and incident heart failure (HF). After exclusion of prevalent cases of respective outcome, proteins that met Bonferroni-corrected significance were analysed in multivariable Cox regression models. Significant associations were identified between five proteins [GAL4 (hazard ratio; 95% confidence interval: 1.17-1.41), CTSD (1.15-1.37), CD163 (1.09-1.30), IGFBP2 (1.05-1.30), and FABP4 (1.04-1.29)] and ACM and four proteins [GAL4 (1.38-1.56), CTSD (1.14-1.43), CD163 (1.09-1.36), and IGFBP2 (1.03-1.35)] with CVM. Three proteins [GAL4 (1.14-1.57), CTSD (1.12-1.50), and FABP4 (1.05-1.55)] were significantly associated with incident CE and two [GAL4 (1.03-1.54) and CTSD (1.01-1.46)] were associated with incident HF after adjusting for traditional risk factors including N-terminal pro-brain natriuretic peptide.

Conclusions

In a general Swedish population, four proteins previously shown to be associated with diabetes were associated with ACM and CVM. Three proteins were associated with incident CE. Finally, GAL4 and CTSD displayed novel associations with incident HF and were the only proteins associated with all outcomes.

Project description:BACKGROUND: Obesity is a multifactorial disorder influenced by genetic and environmental factors. Animal models of obesity are required to help us understand the signaling pathways underlying this condition. Zebrafish possess many structural and functional similarities with humans and have been used to model various human diseases, including a genetic model of obesity. The purpose of this study was to establish a zebrafish model of diet-induced obesity (DIO). RESULTS: Zebrafish were assigned into two dietary groups. One group of zebrafish was overfed with Artemia (60 mg dry weight/day/fish), a living prey consisting of a relatively high amount of fat. The other group of zebrafish was fed with Artemia sufficient to meet their energy requirements (5 mg dry weight/day/fish). Zebrafish were fed under these dietary protocols for 8 weeks. The zebrafish overfed with Artemia exhibited increased body mass index, which was calculated by dividing the body weight by the square of the body length, hypertriglyceridemia and hepatosteatosis, unlike the control zebrafish. Calorie restriction for 2 weeks was applied to zebrafish after the 8-week overfeeding period. The increased body weight and plasma triglyceride level were improved by calorie restriction. We also performed comparative transcriptome analysis of visceral adipose tissue from DIO zebrafish, DIO rats, DIO mice and obese humans. This analysis revealed that obese zebrafish and mammals share common pathophysiological pathways related to the coagulation cascade and lipid metabolism. Furthermore, several regulators were identified in zebrafish and mammals, including APOH, IL-6 and IL-1? in the coagulation cascade, and SREBF1, PPAR?/?, NR1H3 and LEP in lipid metabolism. CONCLUSION: We established a zebrafish model of DIO that shared common pathophysiological pathways with mammalian obesity. The DIO zebrafish can be used to identify putative pharmacological targets and to test novel drugs for the treatment of human obesity.

Project description:Type 2 diabetes mellitus (T2DM) is a major cardiovascular disease (CVD) risk factor. Identification of genetic risk factors for CVD is important to understand disease risk. Two recent genome-wide association study (GWAS) meta-analyses in the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) consortium detected CVD-associated loci.Variants identified in CHARGE were tested for association with CVD phenotypes, including vascular calcification, and conventional CVD risk factors, in the Diabetes Heart Study (DHS) (n?=?1208; >80% T2DM affected). This included 36 genotyped or imputed single nucleotide polymorphisms (SNPs) from DHS GWAS data. 28 coding SNPs from 14 top CHARGE genes were also identified from exome sequencing resources and genotyped, along with 209 coding variants from the Illumina HumanExome BeadChip genotype data in the DHS were also tested. Genetic risk scores (GRS) were calculated to evaluate the association of combinations of variants with CVD measures.After correction for multiple comparisons, none of the CHARGE SNPs were associated with vascular calcification (p?<?0.0014). Multiple SNPs showed nominal significance with calcification, including rs599839 (PSRC1, p?=?0.008), rs646776 (CELSR2, p?=?0.01), and rs17398575 (PIK3CG, p?=?0.009). Additional COL4A2 and CXCL12 SNPs were nominally associated with all-cause or CVD-cause mortality. Three SNPs were significantly or nominally associated with serum lipids: rs3135506 (Ser19Trp, APOA5) with triglycerides (TG) (p?=?5×10(-5)), LDL (p?=?0.00070), and nominally with high density lipoprotein (HDL) (p?=?0.0054); rs651821 (5'UTR, APOA5) with increased TGs (p?=?0.0008); rs13832449 (splice donor, APOC3) associated with decreased TGs (p?=?0.0015). Rs45456595 (CDKN2A, Gly63Arg), rs5128 (APOC3, 3'UTR), and rs72650673 (SH2B3, Glu400Lys) were nominally associated with history of CVD, subclinical CVD, or CVD risk factors (p?<?0.010). From the exome chip, rs3750103 (CHN2, His204Arg/His68Arg) with carotid intima-medial thickness (IMT) (p?=?3.9×10(-5)), and rs61937878 (HAL, Val549Met) with infra-renal abdominal aorta CP (AACP) (p?=?7.1×10(-5)). The unweighted GRS containing coronary artery calcified plaque (CAC) SNPs was nominally associated with history of prior CVD (p?=?0.033; OR?=?1.09). The weighted GRS containing SNPs was associated with CAC and myocardial infarction (MI) was associated with history of MI (p?=?0.026; OR?=?1.15).Genetic risk factors for subclinical CVD in the general population (CHARGE) were modestly associated with T2DM-related risk factors and CVD outcomes in the DHS.
