Selenium at nutritional levels is required for cell homeostasis, playing a role as an anti-oxidant through selenoproteins, thus, act chemo-preventive against cancer. In contrast, supra-nutritional levels act as pro-oxidant toxic in tumour cells. [39] Selenium has bimodal biological action

Selenium at nutritional levels or low concentrations is required for cell homeostasis, playing a role as an anti-oxidant through selenoproteins, thus, act chemo-preventive against cancer. In contrast, supra-nutritional levels or higher concentrations act as pro-oxidant in tumour cells, thus can be exploited as chemo-therapeutic against cancer .

Selenium deficiency occurs when an organism lacks the required levels of selenium, a critical nutrient in many species.Deficiency, although relatively rare in healthy well-nourished individuals, [1] can have significant negative results, [2] affecting the health of the heart and the nervous system; contributing to depression, anxiety, and dementia; and interfering with reproduction and gestation.

This gene encodes a member of the glutathione peroxidase family, consisting of eight known glutathione peroxidases (GPx1-8) in humans. Mammalian Gpx1 (this gene), Gpx2, Gpx3, and Gpx4 have been shown to be selenium-containing enzymes, whereas Gpx6 is a selenoprotein in humans with cysteine-containing homologues in rodents.
Intuitively, if plasma levels of T 3 fall, there would be a compensatory rise in TSH, the secretion of which is inhibited by T 3. However, because type 2 deiodinase mediates the conversion of T 4 to T 3 within the pituitary and CNS, and because caloric restriction does not affect this enzyme, local T 3 levels in the pituitary are normal.
