Abstract

Chronic renal disease (CRD) associated with cardiovascular disease (CVD) and/or type 2 diabetes (T2D) is a significant problem in Aboriginal Australians. Whole exome sequencing data (N = 72) showed enrichment for ClinVar pathogenic variants in gene sets/pathways linking lipoprotein, lipid and glucose metabolism. The top Ingenuity Pathway Analysis canonical pathways were Farsenoid X Receptor and Retinoid Receptor (FXR/RXR; (P = 1.86 × 10-7), Liver X Receptor and Retinoid Receptor (LXR/RXR; P = 2.88 × 10-6), and atherosclerosis signalling (P = 3.80 × 10-6). Top pathways/processes identified using Enrichr included: Reactome 2016 chylomicron-mediated lipid transport (P = 3.55 × 10-7); Wiki 2016 statin (P = 8.29 × 10-8); GO Biological Processes 2017 chylomicron remodelling (P = 1.92 × 10-8). ClinVar arylsulfatase A pseudodeficiency (ARSA-PD) pathogenic variants were common, including the missense variant c.511 G > A (p.Asp171Asn; rs74315466; frequency 0.44) only reported in Polynesians. This variant is in cis with known ARSA-PD 3' regulatory c.*96 A > G (rs6151429; frequency 0.47) and missense c.1055 A > G (p.Asn352Ser; rs2071421; frequency 0.47) variants. These latter two variants are associated with T2D (risk haplotype GG; odds ra...Continue Reading

Cell Biology of Lipids

Lipids are essential in many biological functions, including membrane structure, energy storage, and cell signaling. Find the latest research on the cell biology of lipids here.

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
