Additionally, one study of over 400 human subjects found different regression profiles for selenium and GPx-1 activity for each genotype: the correlation of GPx-1 activity with plasma selenium concentrations was higher for the Pro/Pro genotype than the Leu/Leu genotype, providing evidence that GPx-1 genotypes can modulate the expression of GPx-1 in response to selenium in vivo (183)

Thus, ITC+Se-mediated increase in selenoprotein expression, such as TrxR1 and GPx2, may be more relevant in normal cells as a cancer-preventive measure to inhibit malignant transformation prior to the initiation of carcinogenesis
