近日,来自美国和韩国的科学家们在国际学术期刊Cancer research上发表了一项最新研究进展,他们发现一种具有基因毒性的小分子能够对存在DNA错配修复机制缺陷的癌细胞发挥特异性杀伤作用。该研究为癌症的精准治疗提供了一种新选择。
 
利用具有基因毒性的小分子干扰癌细胞的分裂是开发化疗药物的一个主要目标,但是存在DNA错配修复缺陷的癌细胞会对大多数传统化疗药物产生抵抗。在这项最新研究中,研究人员发现一种叫做baicalein的小分子能够特异性杀伤存在DNA错配修复缺陷的癌细胞。
 
他们首先发现baicalein能够优先结合发生错配的DNA,并通过错配修复依赖性机制诱导DNA损伤应答。MutSα是参与DNA错配修复的一个关键蛋白,研究人员发现在存在MutSα的细胞中,baicalein能够与MutSα结合解除其与CHK2的相互作用导致S期停滞以及细胞存活。但是在缺失MutSα的癌细胞中,由于baicalein的存在以及MutSα的缺失导致癌细胞无法正常进行DNA错配修复,细胞内出现大量DNA双链断裂,进而导致了细胞凋亡的发生。
 
除此之外,研究人员还在异种移植肿瘤小鼠模型中检测了baicalein的作用,发现baicalein同样能够对缺失MutSα的癌细胞发挥特异性杀伤作用,导致肿瘤萎缩。他们还在结肠特异性敲除MSH2的小鼠中建立AOM-DSS诱导的结肠肿瘤,随后用baicalein进行治疗,也可以抑制肿瘤的生长。
 
总的来说,这项研究发现baicalein对于存在DNA错配修复机制缺陷的癌细胞具有特异性杀伤作用,该研究或将为患有该类肿瘤的病人提供一个更好的治疗选择。.

JAMA Oncology:治疗前列腺癌——看基因选药

在一项小型临床研究中,来自约翰霍普金斯基梅尔癌症中心和詹姆斯布坎南布拉迪泌尿学研究所的科学家们发现患有晚期前列腺癌同时携带雄激素受体剪切突变7(AR-V7)的男性患者对传统化疗方法的药物应答情况与不携带突变的前列腺癌患者一样好。近日,相关研究结果发表在国际学术期刊JAMA Oncology。   研究人员指出,这项研究发现可能对于携带AR-V7突变的病人具有非常重要的意义,他们的研究

NRR:化疗药物的神经毒性

化疗是肿瘤的主要治疗手段之一,在取得疗效的同时,还发现这种治疗方法会引起一系列神经系统副作用,如血管并发症、癫痫、情绪异常、认知功能障碍和周围神经病变。化疗引起背根神经节和背角神经元离子通道变化,引起继发性损伤神经病理痛。尽管现在已开发出许多化疗保护剂,但其作用效果仍不理想。化疗药物可引起海马神经发生和神经可塑性发生变化。发表于2013年6月第17期《中国神经再生研究(英文版)》杂志的“Neuro
