Figure 1From: The cytotoxicity of γ-secretase inhibitor I to breast cancer cells is mediated by proteasome inhibition, not by γ-secretase inhibitionEffect of three different GSIs on the viability/proliferation of six breast cancer cell lines. Breast cancer cells were treated with Z-LLNle-CHO, DAPT, or L-685,458 for 72 hours before relative cell viability/proliferation was measured by MTS assay. Results represent the mean ± standard deviation of three independent experiments. GSI = γ-secretase inhibitor.Back to article page
