Results from FFT in CCF-STTG1 cells stimulated with 10% FBS to induce oscillations following 24hrs treatment with: (A) 2 μM BaP, 4 μM 5-MeCr or a mixture of 2 μM BaP and 4 μM 5-MeCr and (B) 10 μM BaP, 10 μM 5-MeCr, or a mixture of 10 μM BaP and 10 μM 5-MeCr. Data represent at least 30 cells per treatment. Different letters indicate significant difference at p < 0.05 using Tukey’s multiple comparison test. Note that EGF and Barium added 1hr prior to imaging and during loading of the Ca2+ probe fluo-4 were able to reverse the effects of the mixture of BaP and 5MeCr on the frequency of Ca2+ oscillations (B).
