根据斯坦福大学医学院的一项最新研究,将两种药物联合使用可以有效治疗实验小鼠的胰腺癌,其中一种药物已经得到了美国FDA的批准。相关研究结果发表在国际学术期刊Nature medicine上。

 
这两种药物可以影响癌细胞DNA的结构和功能,而非癌细胞内的蛋白质活性,除了能够治疗胰腺癌,这种联合使用还可以减缓人类肺癌细胞在小鼠体内的生长,这项研究找到了这些类型药物治疗疾病的潜在作用,研究人员希望能够尽快在胰腺癌病人身上进行进一步临床验证。
 
研究人员指出,胰腺癌是人类癌症中最致命的类型之一,并且它的发病率逐年增加。KRAS基因突变是导致胰腺癌发生的主要原因,虽然阻断Ras信号途径在胰腺癌治疗方面非常具有应用前景,但相关治疗药物常具有严重的药物副作用,从而限制了这些药物的使用。
 
在这项研究中,研究人员对应用小分子抑制剂靶向染色质调控因子作为胰腺导管腺癌(PDAC)治疗的可能治疗药物进行了检测。他们发现一种BET蛋白家族抑制剂--JQ1能够通过抑制MYC活性和炎症信号抑制小鼠PDAC发展,组蛋白去乙酰化酶抑制剂SAHA能够与JQ1协同放大细胞死亡效应,能够对晚期PDAC有更加有效的抑制作用。
 
最后,研究人员直接在小鼠的胰腺中应用了基于CRISPR-CAS9的基因编辑方法,他们在成年小鼠的胰腺中敲除了p57,结果表明联合使用药物并不能有效地诱导细胞死亡,这说明BET和HDAC抑制剂在PDAC中发挥的诱导细胞死亡作用需要对p57进行去抑制,而p57本身可以阻断细胞分裂。
 
研究人员指出,他们希望在未来五年内能够对这种药物联合使用方法进行临床验证,同时也希望了解这种治疗方法是否对其他情况下的癌症同样有效。
