PaCa 5061 cell viability following Gemcitabine, 5-FU, Cetuximab, and Gefitinib treatment. Cell proliferation following drug treatment for 72 h was estimated by MTT test. 6A. Dose-dependent inhibition of cell proliferation in Gemcitabine and 5-FU treated cells as well as in Cetuximab and Gefitinib treated cells (6B). Quantitative values are means ± SEM from 3 independent experiments performed in quadruplicate.
