丹娜-法伯癌症研究所:新型靶向药物adavosertib治疗子宫癌具有惊人效果

2020-04-27 Allan MedSci原创

丹娜-法伯癌症研究所(Dana-Farber Cancer)的研究人员在一项针对难治性子宫癌患者的临床试验中证明,新型DNA损伤靶向药物adavosertib导致肿瘤缩小了近三分之一。

丹娜-法伯癌症研究所(Dana-Farber Cancer)的研究人员在一项针对难治性子宫癌患者的临床试验中证明,新型DNA损伤靶向药物adavosertib导致肿瘤缩小了近三分之一。初步结果将在妇科肿瘤学会(SGO)虚拟会议上在线发表。

某些癌细胞不断增殖会产生一种称为“复制压力”的状况,在这种情况下,它们有效复制其DNA的能力会大大受损。细胞周期包括几个检查点,这些检查点可终止细胞周期,以便在必要时可以检查并修复受损DNA。在某些癌症中,由于基因突变或其他问题,检查点无法正常工作,即使DNA损伤不断累积。

子宫癌就是这样一种癌症,超过90%的病例存在TP53基因突变。如果没有有效的TP53,细胞就会进入DNA复制阶段,并造成广泛的DNA损伤。adavosertib靶向一种名为WEE1的蛋白质,该蛋白质有助于调节G2 / M检查点,使肿瘤细胞承受更多的DNA损伤,以致它们无法生存。
