Cancer Cell:癌症凋亡细胞的突变种(BIK-DD)可引发胰腺癌干细胞凋亡

4月14日,台湾《联合晚报》报道说,台湾“中央研究院”院士洪明奇领导的研究团队从正常细胞中找到一种癌症凋亡细胞的突变种(BIK-DD),适度表现后,可引起癌症干细胞的凋亡,却不会误杀正常细胞,可望给几无存活机会的胰脏癌患者带来生机。 洪明奇14日出席相关研讨会并发表特别演讲,他的研究成果引起与会癌症医学专家热烈讨论。相关研究成果刊登在了国际杂志Cancer Cell上。 报道说,胰脏癌患者的5

4月14日,台湾《联合晚报》报道说,台湾“中央研究院”院士洪明奇领导的研究团队从正常细胞中找到一种癌症凋亡细胞的突变种(BIK-DD),适度表现后,可引起癌症干细胞的凋亡,却不会误杀正常细胞,可望给几无存活机会的胰脏癌患者带来生机。

洪明奇14日出席相关研讨会并发表特别演讲,他的研究成果引起与会癌症医学专家热烈讨论。相关研究成果刊登在了国际杂志Cancer Cell上。

报道说,胰脏癌患者的5年存活率只有3%至4%,几乎是所有癌症患者中最低的,胰脏癌因此又有“癌症中的癌症”之称。洪明奇完成的动物实验发现,经过癌症凋亡细胞突变种治疗后的胰脏癌老鼠,肿瘤均明显变小,而且六成以上可存活1年以上;反观未接受治疗的对照组老鼠,全部在三四十天后即死亡。

洪明奇说,不少癌症经化学治疗及放射线治疗后,仍会在一段时间后复发,主要是癌症干细胞的分化能力太强,如果未能彻底歼灭,即可能复发并蔓延,防不胜防。他采取的基因治疗模式,就是想办法让癌症干细胞自然凋亡,而达到彻底治疗目的。

洪明奇研究团队采用的癌症凋亡细胞(BIK)一般人体内就有,即存在于正常细胞里,也存在于癌细胞中;但这种凋亡细胞平常并不会特别表现,无法杀死癌症干细胞。洪明奇找到癌症凋亡细胞的突变种(BIK-DD),且可调控到让它只在癌症干细胞中大量表现,而不会表现于正常细胞中。

KrasG12D-Induced IKK2/β/NF-κB Activation by IL-1α and p62 Feedforward Loops Is Required for Development of Pancreatic Ductal Adenocarcinoma

Constitutive Kras and NF-κB activation is identified as signature alterations in pancreatic ductal adenocarcinoma (PDAC). However, how NF-κB is activated in PDAC is not yet understood. Here, we report that pancreas-targeted IKK2/β inactivation inhibited NF-κB activation and PDAC development in KrasG12D and KrasG12D;Ink4a/ArfF/F mice, demonstrating a mechanistic link between IKK2/β and KrasG12D in PDAC inception. Our findings reveal that KrasG12D-activated AP-1 induces IL-1α, which, in turn, activates NF-κB and its target genes IL-1α and p62, to initiate IL-1α/p62 feedforward loops for inducing and sustaining NF-κB activity. Furthermore, IL-1α overexpression correlates with Kras mutation, NF-κB activity, and poor survival in PDAC patients. Therefore, our findings demonstrate the mechanism by which IKK2/β/NF-κB is activated by KrasG12D through dual feedforward loops of IL-1α/p62.
