Figure 2From: Estrogen enhanced cell-cell signalling in breast cancer cells exposed to targeted irradiation Influence of E2 and TAM on radiation-induced MN formation. A fraction of MCF-7 (A) or MDA-MB-231 (B) cells were individually irradiated with 5 3He2+ particles without or with pre-treatment with E2 or E2+TAM (*, P < 0.05 compared to the MN yield without E2 treatment).Back to article page
