| Naturally occurring element. Selenium is incorporated into selenoproteins, such as glutathione peroxidases (GPxs) and thioredoxin reductases (TrxRs), which play critical roles in protecting cells from oxidative damage. Involved in GPx, TrxR, ans Selenoprotien P which protect normal cells from oxidative stress. Important in Thyroid hormone metabolism, immune system regulation, reproductive health, and Brain and heart protection. -recommended daily allowance (RDA) for selenium is about 55 µg/day for adults. (upper tolerance 400ug/day) -One Brazil nut may contain 50-300ug/nut Sodium selenite (Na₂SeO₃) is a selenium compound with well-documented anticancer and chemopreventive properties -Oxidation state: +4 (selenite form of selenium) -Type: Inorganic selenium compound (water-soluble) -Sodium selenite generates reactive oxygen species (ROS) selectively in tumor cells. -Induces cytochrome c release, caspase-3 activation, and DNA fragmentation. -Reduces VEGF expression and endothelial cell migration. -Blocks cell division at G2/M phase -Suppresses MMP-2 and MMP-9 activity -Activates p53 -Inhibits NF-κB -PI3K/Akt/mTOR Suppression -Inactivation of Thioredoxin/Glutathione systems -NRF2 inhibition in cancer cell might be connected with O2 level Narrow therapeutic window: -Low micromolar (≤5 µM) → anticancer -High (>10 µM) → toxic to normal cells Some Selenium Supplements use Sodium Selenite as the active ingredient. - NOW Foods Selenium, Nature's Bounty Selenium, etc Other common form is Selenomethionine, as it is better absorbed (found in brazil nuts), but might be less effective? | Category | Role in cancer | | -------------------------------- | ----------------------------------------------------------------------------------------------- | | Sodium Selenium (selenite) | Direct cytotoxic redox poison | | Selenium (organic / nutritional) | **Redox buffer & immune modulator** (generally *anti-therapy* when oxidative stress is desired) | | SeNPs | Tunable redox-signaling anticancer platform | Selenium (Organic / Nutritional) — Cancer-Relevant Pathways
