Figure 7

4HC enhances cytotoxicity induced by doxorubicin and cisplatin in SK-N-BE (2) and IMR-32 cells. (a–c) Cell viability measured by MTT assay and (d) representative photomicrographs of (a) SK-N-BE (2) and (b) IMR-32 treated with 5 μM 4HC and (c) SH-SY5Y cells treated with 25 μM 4HC, or with 5 μM doxorubicin (Dox) or 100 μM cisplatin (CP) with or without 4HC for 24 h. All data are . , , and versus control. ###Combined treatment versus Dox or CP alone; ANOVA with Fisher’s LSD test. .
