Figure 1: Biflorin inhibits cell growth by inhibiting EGFR expression. a) Biflorin chemical structure; b) Growth inhibition of biflorinon MCF-10A cells and stained with Crystal Violet; c) Effect of biflorin on expression of EGFR; d) Time- and Dose-dependent SK-BR3 growth inhibition. Etoposide was used as a positive control. The data shown on b, c and d are representative of results obtained in at least three separate experiments in triplicate.
