Susceptibility of SK-HEP-1 derivative cells to anti-cancer drugs. Cells were subjected to an MTS assay to evaluate the viability of SK-HEP-1 (open circles) and SK-sphere (closed circles) cells in the presence of anti-cancer drugs (A, 5-FU; B, cisplatin; C, carboplatin, D, doxorubicin; E, docetaxel; F, SAHA; G, irinotecan; H, sunitinib; and I, sorafenib). Except for sorafenib, SK-sphere cells showed higher viability in the presence of the tested anti-cancer drugs. P values were calculated with repeated-measures ANCOVA.
