Description générale

Astaxanthin (AST) is a red dietary carotenoid. It is mainly found in aquatic animals and microalgae, such as Haematococcus pluvialis and Chlorella zofingiensis.

Application

Astaxanthin has been used:
  • as an antioxidant to study its effect on Brachionus manjavacas (Rotifera) population growth
  • to study its effects on the treatment of diabetic retinopathy.
  • to investigate its role in restoring the expression of Nrf2 (nuclear factor erythroid 2 p45-related factor 2) and glutathione S-transferase P1 (GSTP1) through epigenetic modification in human prostate LNCaP cells.

Actions biochimiques/physiologiques

In vivo and in vitro studies propose that astaxanthin (AST) possesses health-promoting activities, signifying its potential use in the prevention of various diseases, such as cancers and Parkinson′s disease. Due to its bright red colour, AST has been used as a food colorant in animal feeds.
Astaxanthin is a potent antioxidant with antiproliferative, neuroprotective and anti-inflammatory activity. Astaxanthin protects against oxidative stress, inhibiting NF-KB, suppressing pro-inflammatory genes and suppressing production of pro-inflammatory compounds nitric oxide, prostaglandin E2, TNF-α, and interleukin-1β. Astaxanthin′s protection of cells from oxidative stress generated by TNF-α and palmitate has been shown to ameliorate insulin resistance. Astaxanthin has also been shown to be an inhibitor of PPARγ.

Exercise-induced reactive oxygen and nitrogen species are increasingly considered as beneficial health promotion. Astaxanthin (ASX) has been recognized as a potent antioxidant suitable for human ingestion. We investigated whether ASX administration suppressed antioxidant enzyme activity in moderate-intensity exercise. Seven-week-old male
