PNAS:抑癌基因失活将导致胃肠道间质瘤恶性进展

2019-10-24 佚名 中国科学报

中国科学院上海营养与健康研究所—长征医院联合转化医学中心王跃祥团队在国际上首次解析了胃肠道间质瘤恶性进展新机制,解析了抑癌基因的失活是间质瘤恶性进展的重要分子机制,提供了区分间质瘤恶性程度的分子标记物,为间质瘤的精准治疗提供依据。该研究成果 10 月 22 日发表于美国《国家科学院院刊》。

中国科学院上海营养与健康研究所—长征医院联合转化医学中心王跃祥团队在国际上首次解析了肠道间质瘤恶性进展新机制,解析了抑癌基因的失活是间质瘤恶性进展的重要分子机制,提供了区分间质瘤恶性程度的分子标记物,为间质瘤的精准治疗提供依据。该研究成果 10 月 22 日发表于美国《国家科学院院刊》。

研究人员在优化新型驱动基因发现的基础上,建立了一套肠道间质瘤驱动基因的研究体系,首次发现间质瘤中位于 22 号染色体的新型抑癌基因 DEPDC5,证明其编码蛋白 DEPDC5 能抑制间质瘤细胞增殖和生长。这个蛋白正常发挥功能时,能阻止间质瘤生长。但当其编码基因突变而处于失活状态时,间质瘤恶性程度越高,该蛋白表达量越低。研究表明,DEPDC5 蛋白的失活会促进间质瘤的恶性进展。

“学术界 20 年前就推测胃肠道间质瘤 22 号染色体存在抑瘤基因,现在我们终于找到了这个基因。” 王跃祥说,“早期间质瘤体积小,生长能力有限,原因之一是 DEPDC5 有抑癌功能。一旦 DEPDC5 失活,间质瘤增殖能力就增强,推动其向恶性方向发展。”

专家认为,该研究对晚期间质瘤的治疗和有效预防、延缓间质瘤的进展意义重大,并为 DEPDC5 失活的间质瘤患者带来福音,为未来的临床应用奠定了理论基础。

Nat Genet:CRISPR与DNA条形码 “联姻”,追踪癌症发展

CRISPR作为一项基因编辑新技术,已在生物学中得到了广泛应用。现在,斯坦福大学的科学家找了一个新方法——将CRISPR/Cas9与DNA条形码技术联合起来,可以修饰小鼠的肺部中与癌症相关的基因,并能精确追踪肿瘤的单个细胞。这一“强强联合”或将显著加速癌症研究和药物开发。

Gene Therapy:好心帮倒忙,抑癌基因 TET2 或降低 CAR- T 疗效

今天 CAR- T 先驱 Carl June 小组在《自然》杂志报道一例 CLL 患者的神奇运气。这位患者 78 岁时需要 CAR- T 疗法,第一次输入自体 CD19 CAR- T 除了发生严重细胞因子风暴(CRS)外没什么其它后果。因为疗效不好可能是因为被迫使用了 IL6 抗体,所以两个月后又把剩下的 CAR- T 细胞输入给该患者。这次他可是中了彩票了。虽然两个月还没啥反应,但两个月后突然开

Nature Commun:癌基因?错!其实它也是抑癌基因

许多肿瘤过表达PLK1基因,于是,研究人员就认为它是促瘤剂。最近,西班牙癌症研究中心(CNIO)和德国癌症研究中心(DKFZ)的研究人员《Nature Communications》发文,报道在一些乳腺肿瘤中,PLK1的功能反而是抑制癌症。

多年来,各类癌症捷报频传。但令人惋惜的是,在过去长达40年的时间里,喜讯似乎一直与白血病患者无缘。近日的一项研究或许可以打破这一僵局。耶路撒冷希伯来大学医学院的研究小组开发了一种新的生物药物,对于实验室小鼠的急性白血病治愈率高达50%。

Molecular Cell:揭示抑癌基因PTEN抑制糖酵解活性新机制

瓦博格效应(Warburg effect),即肿瘤细胞即使在氧气充足的情况下仍主要通过糖酵解途径代谢葡萄糖,是肿瘤细胞的一大特征。PTEN作为抑癌基因,通过抑制PI3K/AKT信号通路减少葡萄糖摄取等方式对糖酵解活性发挥间接抑制作用。但PTEN是否与糖酵解代谢酶相互作用直接抑制糖酵解活性尚不清楚。
