摘要：
Amplification of the MYCN oncogene is a strong predictor of treatment failure and chemo-resistance in childhood neuroblastoma. Stable expression of two partial MYCN gene fragments in antisense orientation reduced Mycn protein expression in an MYCN-amplified neuroblastoma tumor cell line, however; antisense cells did not exhibit an increased in vitro sensitivity to cytotoxic ol differentiating agents. In contrast, partial MYCN sense transfectants exhibited increased resistance to cytotoxic drugs. These data suggest that the chemo-resistance of MYCN-amplified neuroblastoma cells is complex, and may be due to factors additional to Mycn protein expression.
