TLDR
The biology of urate metabolism and its role in disease is discussed and recent studies identifying SLC2A9, which encodes the glucose transporter family isoform Glut9, as a major determinant of plasma uric acid levels and of gout development are identified.
Abstract
Uric acid is the metabolic end product of purine metabolism in humans. It has antioxidant properties that may be protective but can also be pro-oxidant, depending on its chemical microenvironment. Hyperuricemia predisposes to disease through the formation of urate crystals that cause gout, but hyperuricemia, independent of crystal formation, has also been linked with hypertension, atherosclerosis, insulin resistance, and diabetes. We discuss here the biology of urate metabolism and its role in disease. We also cover the genetics of urate transport, including URAT1, and recent studies identifying SLC2A9, which encodes the glucose transporter family isoform Glut9, as a major determinant of plasma uric acid levels and of gout development.

The NLRP3 inflammasome instigates obesity-induced inflammation and insulin resistance

TL;DR: It is established that calorie restriction and exercise-mediated weight loss in obese individuals with type 2 diabetes is associated with a reduction in adipose tissue expression of Nlrp3 as well as with decreased inflammation and improved insulin sensitivity, and that the NlrP3 inflammasome senses obesity-associated danger signals and contributes to obesity-induced inflammation and insulin resistance.

Recent advances in 2D and 3D in vitro systems using primary hepatocytes, alternative hepatocyte sources and non-parenchymal liver cells and their use in investigating mechanisms of hepatotoxicity, cell signaling and ADME.

Patricio Godoy, +94 more
TL;DR: This review encompasses the most important advances in liver functions and hepatotoxicity and analyzes which mechanisms can be studied in vitro and how closely hepatoma, stem cell and iPS cell–derived hepatocyte-like-cells resemble real hepatocytes.

The SLC2 (GLUT) family of membrane transporters.

TL;DR: This review describes the major characteristics of the 14 GLUT family members and concludes that GLUTs 1-5 are the most thoroughly studied and all have well established roles as glucose and/or fructose transporters in various tissues and cell types.

Global epidemiology of gout: prevalence, incidence and risk factors

TL;DR: Data from epidemiological studies from diverse regions of the world are synthesized to depict the geographic variation in gout prevalence and incidence, and indicate that the distribution of gout is uneven across the globe, with prevalence being highest in Pacific countries.

Inflammation and metabolic disorders

TL;DR: Dysfunction of the immune response and metabolic regulation interface can be viewed as a central homeostatic mechanism, dysfunction of which can lead to a cluster of chronic metabolic disorders, particularly obesity, type 2 diabetes and cardiovascular disease.

Gout-associated uric acid crystals activate the NALP3 inflammasome

TL;DR: It is shown that MSU and CPPD engage the caspase-1-activating NALP3 (also called cryopyrin) inflammasome, resulting in the production of active interleukin (IL)-1β and IL-18 in mice deficient in the IL-1β receptor.

Uric acid provides an antioxidant defense in humans against oxidant- and radical-caused aging and cancer: a hypothesis.

TL;DR: It is shown that, at physiological concentrations, urate reduces the oxo-heme oxidant formed by peroxide reaction with hemoglobin, protects erythrocyte ghosts against lipid peroxidation, and protects ERYthrocytes from peroxidative damage leading to lysis.

Uric acid and cardiovascular risk.

TL;DR: This review summarizes relevant studies concerning uric acid and possible links to hypertension, renal disease, and cardiovascular disease and presents current evidence.
