Liver copper content of rats hypo- or hyperresponsive to dietary cholesterol.

The question addressed is whether cholesterol intake reduces the hepatic copper content in rats. For this purpose we have compared the hepatic copper content of two selected rat inbred strains after feeding the animals a control or a high fat, high cholesterol diet. One strain was dietary cholesterol resistant (SHR/OlaIpcv), whereas the other strain was susceptible to dietary cholesterol (BN-Lx/Cub).

Cholesterol and copper in the liver of rabbit inbred strains with differences in dietary cholesterol response.

In order to investigate whether cholesterol intake influences the hepatic copper content of rabbits, we compared the hepatic copper content of two rabbit inbred strains after feeding the animals a control or a cholesterol-rich diet. One strain was not reactive to dietary cholesterol (IIIVO/JU), whereas the other strain was reactive to dietary cholesterol (AX/JU). The coefficient of inbreeding (F) >0.
