enhancement of apoptotic and autophagic induction by a novel synthetic c-1 analogue of 7-deoxypancratistatin in human breast adenocarcinoma and neuroblastoma cells with tamoxifen

乳腺癌是最常见的癌症之一，除在北美的妇女。目前许多抗癌药物，包括电离辐射，通过DNA损伤诱导细胞凋亡。不幸的是，这种治疗方法有非选择性的肿瘤细胞，在正常细胞产生类似的毒性。我们已经报道（PST），通过天然化合​​物pancratistatin的选择性诱导肿瘤细胞凋亡。最近，一种新的PST模拟，7 deoxypancratistatin（JCTH-4）的C-1乙酰衍生物，从头合成产生，它在多种癌细胞株展品媲美选择性诱导凋亡活性。最近，自噬已被牵连在恶性肿瘤亲生存和死亡机制在化疗反应。三苯氧胺（TAM）总是表现出亲生存在许多癌症细胞自噬的诱导。在这项研究中，JCTH-4单独和谭相结合的疗效，诱导细胞死亡在人类乳腺癌canceR（MCF7细胞）和神经母细胞瘤细胞（SH-SY5Y细胞）进行了评估。谭单独诱导细胞自噬，但单独JCTH-4微不足道的细胞死亡而造成的一些诱导的自噬诱导细胞凋亡的重要。有趣的是，组合的治疗取得了大幅增加在细胞凋亡和自噬的诱导。我们监测的组合使用治疗时间推移显微镜MCF7细胞的形态学变化时间依赖性接受TAM诱导细胞自噬，JCTH-4诱导的细胞凋亡和自噬，并加速细胞死亡。我们已经证明了这些化合物诱导细胞凋亡/自噬在这些癌细胞的线粒体定位。重要的是，这些治疗并不影响非癌的人成纤维细胞的生存。因此，这些结果表明，JCTH-4在与谭相结合，可以作为一个安全和非常强大的抗癌疗法对乳腺癌和神经母细胞瘤细胞。
