Figure 2.

Cell surface sialylation and drug-induced cell death. HBL-2 cells were incubated with etoposide (30 µg/ml). After 72 h, cell viability decreased more in neuraminidase pretreated cells compared with not pretreated cells (*P=0.0021). Data are representative of two independent experiments. N(–), no neuraminidase pretreatment; N(+), neuraminidase pretreatment.
