Figure 5From: Selenized milk casein in the diet of BALB/c nude mice reduces growth of intramammary MCF-7 tumors Tumor Se levels on a dry matter basis. MCF-7 tumors were excised from mice at day 70 of Se-casein treatment and subjected to Se analysis. Values are means ± SE for each treatment group (n = 11, 10, 14, and 13, respectively). The P-value represents the linear effect of dietary Se level.Back to article page
