Diabetes:含有半胱天冬酶招募结构域的细胞凋亡抑制子能够改善类淀粉蛋白诱导的β细胞凋亡和JNK通路的激活

2017-07-24 MedSci MedSci原创

90%的2型糖尿病人体内都存在胰岛类淀粉蛋白,其会造成β细胞凋亡和胰岛素分泌不足。含有半胱天冬酶招募结构域的细胞凋亡抑制子(ARC)能够结合到内源和外源细胞凋亡通路的某些组分上从而使该通路失活。最近发现ARC在胰岛β细胞中表达。本文利用胰岛类淀粉样变性的人类胰岛类淀粉多肽转基因鼠模型,发现敲低ARC能够增加类淀粉蛋白诱导的β细胞凋亡,然而超量表达ARC会降低类淀粉蛋白诱导的细胞凋亡从而保护β细胞。

90%的2型糖尿病人体内都存在胰岛类淀粉蛋白,其会造成β细胞凋亡和胰岛素分泌不足。

含有半胱天冬酶招募结构域的细胞凋亡抑制子(ARC)能够结合到内源和外源细胞凋亡通路的某些组分上从而使该通路失活。最近发现ARC在胰岛β细胞中表达。

本文利用胰岛类淀粉样变性的人类胰岛类淀粉多肽转基因鼠模型,发现敲低ARC能够增加类淀粉蛋白诱导的β细胞凋亡,然而超量表达ARC会降低类淀粉蛋白诱导的细胞凋亡从而保护β细胞。这些影响出现在缺乏胰岛类淀粉蛋白蓄积作用变化的时候,说明ARC在类淀粉蛋白形成的下游发挥作用。因为胰岛类淀粉蛋白可以增加c-Jun氨基末端激酶(JNK)通路激活,因此我们想要探究ARC是否会在类淀粉蛋白形成的胰岛中影响JNK信号通路。

我们发现ARC敲低能够增强JNK通路的激活,然而ARC过表达会降低JNK以及c-Jun磷酸化、c-Jun靶基因表达。免疫沉淀实验正面ARC能够结合JNK,表明JNK和ARC的互作会降低类淀粉蛋白诱导的JNK磷酸化以及下游的信号通路。

以上数据表明ARC过表达减少β细胞中类淀粉蛋白诱导的JNL通路激活和细胞凋亡,此能作为一种策略减少2型糖尿病人中β细胞的损失。

Cancer Res:一种自然产生的前列腺凋亡响应4蛋白的诱饵克服了肿瘤治疗的耐药性

    主要的肿瘤往往是异质的不均一的,由对治疗敏感和耐受的肿瘤细胞构成。有趣的是,在异构肿瘤微环境中,对治疗易受性的处理能够引起治疗耐受性肿瘤的凋亡。     本次研究中,我们鉴定到一个Par4氨基酸末端片段(PAF),它是由各种对治疗易受性的肿瘤细胞随着治疗诱发的肿瘤抑制子Par4蛋白的半胱天冬酶裂解而释放的。PAF引起肿瘤细胞凋亡,对治疗产生耐受性,并

Cell Res:杨巍维教授发现PKM2抑制细胞凋亡的新机制

2016年12月30日,国际学术期刊《细胞研究》(Cell Research)在线发表了中国科学院上海生命科学研究院生物化学与细胞生物学研究所杨巍维研究组的最新研究成果Mitochondrial PKM2 regulates oxidative stress-induced apoptosis by stabilizing Bcl2。该研究揭示了细胞存在氧化压力时,PKM2通过稳定Bcl2从而抑制细胞凋亡的新机制。

PKM2(Pyruvate kinase M2 isoform)是糖酵解途径的关键酶,在肿瘤细胞的发生发展中起重要作用;除了其代谢活性以外,现已有多个实验室报道了其蛋白激酶活性。杨巍维的前期研究发现在EGFR激活的条件下,PKM2可转运至细胞核,磷酸化组蛋白H3,通过表观遗传的方式调控一系列原癌基因的表达(Nature 2011,Cell 2012)。除了在细胞增殖中发挥作用,最近有

自我吞噬和细胞凋亡是两个精细的控制机制来调控细胞的命运。但是,人们对细胞命运走向决定因子的理解还在初期。单胺氧化酶A(MAOA)是一个线粒体酶,且在精神病研究中被人熟知。越来越多的报道表明了MAOA的超表达与前列腺癌(PCa)有关。最近,研究人员展示了MAOA参与了PCa细胞神经内分泌分化的调控,并且该细胞为激素抵抗性PCa(HRPC),是一种致死的疾病类型。接着,最近的报道展示了PCa的神经内分

Nat Med:EGFR抗体介导结肠癌细胞免疫性凋亡

过去二十年来,针对恶性结肠癌(mCRC)患者的治疗有了突飞猛进的发展。患者的存活时间从12个月延长到30个月。这要归功于化疗与靶向疗法,其中包括cetuximab这一单抗药物。Cetuximab是一类嵌合单克隆抗体,它能够特异性识别EGFR并有效治疗mCRC。Cetuximab能够阻断EGFR与其配体的识别,进而影响RAS的信号通路以及ERK的激活。Panitumumab也是一类EGFR的中

Oncotarget:结直肠癌细胞通过诱导血管平滑肌细胞凋亡帮助肿瘤侵袭和转移

结直肠癌癌肿只限于肠壁者的一般预后较好,而浸润到肠外者预后较差,癌瘤浸润广泛、有转移者或有并发症者预后不良。肿瘤血管通常缺乏平滑肌层,这种不稳定性有利于肿瘤的侵袭和转移,因此肿瘤微环境对于血管平滑肌细胞的影响在结直肠癌的治疗中也很重要。
