The over-expression of α-enolase was demonstrated in several cancers, including lung, brain, breast, colon and prostate. In this report, we investigated the effects of α-enolase knockdown on the sensitivity of cancer cells to chemotherapeutic drugs. RNAi-mediated knockdown of α-enolase in A549 and H460 lung, MCF7 breast and CaOV3 ovarian cancer cells caused a significant increase in the sensitivity of these cells to antitubulin chemotherapeutics (e.g., vincristine and taxol), but not to doxorubicin, etoposide or cisplatinum. This is the first demonstration showing the effects of α-enolase expression on the sensitivity of tumor cells to clinically relevant chemotherapeutics.
α-烯醇化酶在包括肺癌、脑癌、乳腺癌、结肠癌和前列腺癌在内的多种癌症中均有过表达。在本报告中,我们研究了敲低α-烯醇化酶对癌细胞对化疗药物敏感性的影响。RNA干扰介导的A549和H460肺癌细胞、MCF7乳腺癌细胞以及CaOV3卵巢癌细胞中α-烯醇化酶的敲低,导致这些细胞对抗微管化疗药物(如长春新碱和紫杉醇)的敏感性显著增加,但对阿霉素、依托泊苷或顺铂则无此效果。这是首次证明α-烯醇化酶表达对肿瘤细胞对临床相关化疗药物敏感性的影响。
