Scientific Reports:乳腺癌和前列腺癌治疗的新希望——新的生物标志物的发现

2015-08-10 sunshine 译 MedSci原创

Cedars-Sinai的研究人员发现了一种新的可在许多乳腺癌和前列腺癌发展过程中起作用的遗传标志物。这一发现将有助于临床医生更好的识别对侵袭性癌症的化疗药物有反应的患者。该研究结果发表于《科学报告》杂志中。“理解和识别生物学标志物是癌症研究和护理过程中中至关重要的一步,”该研究第一作者,Cedars-Sinai外科病研究副主席Michael Freeman博士说道,“以这项研究为例的新的分析策略



Cedars-Sinai的研究人员发现了一种新的可在许多乳腺癌和前列腺癌发展过程中起作用的遗传标志物。这一发现将有助于临床医生更好的识别对侵袭性癌症的化疗药物有反应的患者。该研究结果发表于《科学报告》杂志中。

“理解和识别生物学标志物是癌症研究和护理过程中中至关重要的一步,”该研究第一作者,Cedars-Sinai外科病研究副主席Michael Freeman博士说道,“以这项研究为例的新的分析策略最终将提高我们治疗癌症患者的能力。”

新确定的生物学标志物——半透明相关的甲精或DIAPH3——参与了可使细胞变硬的蛋白反应中。研究发现,当这个生物标志物丢失或表达降低时可使细胞“形状改变”,能够挤过组织空间,导致疾病的发生发展,这种现象称为阿米巴表型。

研究人员可以利用这些知识来更好地确定对常用的化疗药物(紫杉烷类)有反应的患者,这类药物通常用于侵袭性最强的癌症患者的治疗,通过破坏癌细胞蛋白质的结构起作用。

本研究首次确定了针对有阿米巴特性的肿瘤细胞的靶向治疗策略。

“通过识别肿瘤标志物,然后基于此遗传信息制定个性化的治疗方案,可大大提高癌症治疗的效果,”伯恩斯和艾伦研究所的学术事务高级副总裁和主任Shlomo Melmed说道,“这种个性化治疗方案取代了一刀切的癌症治疗方法。”

下一步研究会涉及一个生物标志物工具的开发,将使得研究人员能提前测定这些发现。
