The enhanced cytotoxic effect can be achieved through apoptosis. The results indicated that the sensitivity of ellipticine in p53-mutated NSCLC cells can be enhanced through introduction and nuclear migration of downstream of p53 regulator, p21.人類非小細肺癌細胞玫瑰樹鹼凋亡Human non-small cell lung cancer cellsEllipticineApoptosis
