Table 1 The multiple metabolic toxicities of the A-flight-u Acronym

From: The central role of vascular extracellular matrix and basement membrane remodeling in metabolic syndrome and type 2 diabetes: the matrix preloaded

Multiple injurious stimuli responsible for the production of ROS.
A Angiotensin II (also induces protein kinase C – β isoform)
Amylin (hyperamylinemia) islet amyloid polypeptide toxicity
AGEs/AFEs (advanced glycosylation/fructosylation endproducts)
Apolipoprotein B
Antioxidant reserve compromised
Absence of antioxidant network
ADMA (Asymmetrical DiMethyl Arginine)
Adipose toxicity: Obesity toxicity – Lipid Triad (decreased HDL-C, increased triglycerides and small dense LDL-C)
Adipocytokine toxicity: Increased TNF alpha, Il-6, TGF beta, PAI-I and the increased hormones resistin, leptin and decreased adiponectin.
F Free fatty acid toxicity: Obesity toxicity – Lipid Triad
L Lipotoxicity – Hyperlipidemia – Obesity toxicity – Lipid Triad Leptin toxicity
I Insulin toxicity (endogenous hyperinsulinemia-hyperproinsulinemia) IGF-1 – (GH-IGF-I axis) toxicity: This may serve to increase bone metabolism within the media of the AVW
Inflammation toxicity
G Glucotoxicity (compounds peripheral insulin resistance) and induces reductive stress through the sorbitol/polyol pathway
Pseudohypoxia (increased NADH/NAD ratio)
H Hypertension toxicity
Homocysteine toxicity
T Triglyceride toxicity: Obesity toxicity – Lipid Triad
U Uric Acid – Xanthine Oxidase toxicity: Uric acid is an antioxidant early in physiological range of atherogenesis and a conditional prooxidant late when elevated through xanthine oxidase enzyme and generation of ROS: thus generating the paradoxical (antioxidant → prooxidant):
Endothelial cell dysfunction with eNOS uncoupling, decreased eNO and increased ROS
