Mice genetically engineered to lack glutathione peroxidase 1 (Gpx1 â/â mice) are grossly phenotypically normal and have normal lifespans, indicating this enzyme is not critical for life. However, Gpx1 â/â mice develop cataracts at an early age and exhibit defects in muscle satellite cell proliferation.owever, glutathione peroxidase 4 knockout mice die during early embryonic development. Some evidence, though, indicates reduced levels of glutathione peroxidase 4 can increase life expectancy in mice.
Well to be honest ECUSA has turned away from classical Anglicanism in many ways. I doubt they fast unless you are part of a Traditional Parish. I am continuing Anglican and I do not eat meat on Fridays. This is not out of obligation but because i want to.
1 Vegetarian (lacto-ovo): Most people know of this diet where they eat no beef, pork, poultry, fish, or shellfish, but do eat dairy products. âLactoâ is Latin for milk and âovoâ is for egg.  Vegan: They do not eat meat of any kind including fish and do not eat products that come from animals, such as eggs and milk.
