Growth inhibition of HNSCC cells by (-)-gossypol. (A) UM-SCC-17B and UM-SCC-1 cell lines and primary human oral keratinocytes were continuously exposed to various concentrations of (-)-gossypol over 5 days in a medium composed of a 1:1 mixture of KGM and DMEM. Try pan blue viable cell enumeration assays were performed in triplicate for each data point. Data are expressed as percentages of untreated control values. Error bars indicate standard deviation. (B) UM-SCC-17B and UM-SCC-1 cell lines and primary human oral keratinocytes were continuously exposed to varying concentrations of (-)-gossypol over 6 days for MTT cell survival assays, performed in a medium composed of a 1:1 mixture of KGM and DMEM (n= 10 for each point on the graph). Data are expressed as percentages of untreated control values.
