ACS Cent Sci:庞贝氏症治疗取得突破

2016-05-04 佚名 生物谷

在最新发表于《ACS Central Science》期刊的研究中,纽约大学和荷兰莱顿大学的科学家们在庞贝氏症(Pompe disease)治疗方面取得了重大突破。 庞贝氏症是一种由基因缺陷导致的遗传疾病,患者会缺乏被称为酸性α-葡萄糖苷酶(acid alpha-glucosidase,GAA)的酶,体内肌肉和神经细胞受损,发生进行性肌无力。 在2010年哈里森福特主演电影《良医妙药(E

在最新发表于《ACS Central Science》期刊的研究中,纽约大学和荷兰莱顿大学的科学家们在庞贝氏症(Pompe disease)治疗方面取得了重大突破。

庞贝氏症是一种由基因缺陷导致的遗传疾病,患者会缺乏被称为酸性α-葡萄糖苷酶(acid alpha-glucosidase,GAA)的酶,体内肌肉和神经细胞受损,发生进行性肌无力。

在2010年哈里森福特主演电影《良医妙药(Extraordinary Measures)》上映之后,这种严重疾病吸引了广大公众的注意力。

在新的研究中,研究人员们合成了荧光化学"探针",能够用于医学诊断。

这些工具允许科学家测量人类细胞提取物中GAA酶的水平,允许进行酶水平的快速检测。

研究人员说,这些化合物将为更有效的治疗提供信息,最终导向更好的疗法和个性化医学。

类似的诊断方法已经改进了其他遗传病的医疗。

研究团队包括纽约大学化学系结构生物学实验室的Liang Wu博士和Gideon Davies教授。

Davies教授说:"这些工具允许科学家们在健康人和患者中测量酶的水平。成像活跃的酶水平将有助于评估疾病严重程度,也有助于为更有效的治疗提供信息。"

Wu博士补充道:"这是一个激动人心的突破。我们相信,这项技术将在遗传疾病和癌症治疗中得到广泛的应用。"

Genet in Med:抗癌药物或可助力庞贝氏症患者的治疗

通过将抗癌药物与当前疗法的药物混合可以使得患有严重庞贝氏症的婴儿疾病得到明显的缓解甚至治愈,庞贝氏症是一种罕见的致死性的遗传病,其主要表现为婴儿机体的某种酶类缺少或者水平极低,导致婴儿死亡。此前研究中,来自杜克大学的研究者使用酶替代疗法(ERT)来治疗庞贝氏症,这项新的研究中,研究者对此前的疗法进行了改进和补充,相关研究成果刊登在了10月11日的国际杂志Genetics in Medicine上。
