Figure 7From: Selenized milk casein in the diet of BALB/c nude mice reduces growth of intramammary MCF-7 tumors Effects of selenium treatments on Bax, Bcl-2 and cyclin D1 protein levels. After 70 d of Se-casein treatment, tumors were excised from mice and subjected to western blot analysis for a) Bax, b) Bcl-2, c) Bax:Bcl-2 ratio and d) cyclin D1. Expression levels were normalized to β-tubulin. Values in bar graphs are means ± SE for each treatment group (n = 11, 10, 14 and 13, respectively). P-values represent linear effects of dietary Se level.Back to article page
