Cell Rep:不同肿瘤细胞可相互协作促进恶性黑色素瘤的扩散

2014-07-28 佚名 生物谷

近日,刊登在国际杂志Cell Reports上的一篇研究论文中,来自曼彻斯特大学的研究人员表示,皮肤癌细胞可以互相合作实现在机体中的快速扩散,某些黑色素瘤细胞生长速度尤其之快,但这些癌细胞却并不擅长于侵袭周围的组织,而其它黑色素瘤细胞则完全相反,它们虽然生长缓慢但是可以快速实现周围组织的侵袭,相关研究为开发新型药物来治疗黑色素瘤提供了一定帮助。在肿瘤组织中一种名为捎带细胞(Piggy-backin

近日,刊登在国际杂志Cell Reports上的一篇研究论文中,来自曼彻斯特大学的研究人员表示,皮肤癌细胞可以互相合作实现在机体中的快速扩散,某些黑色素瘤细胞生长速度尤其之快,但这些癌细胞却并不擅长于侵袭周围的组织,而其它黑色素瘤细胞则完全相反,它们虽然生长缓慢但是可以快速实现周围组织的侵袭,相关研究为开发新型药物来治疗黑色素瘤提供了一定帮助。


在肿瘤组织中一种名为捎带细胞(Piggy-backing cells)的快速生长的细胞往往会同高度侵袭性的细胞一起,一旦其到达机体的不同部位就会开启高效的侵袭模式,最终形成新的肿瘤组织。文章中研究者利用透明斑马鱼进行研究,以便其可以观察到癌细胞如何在机体中移动以及如何进行侵袭。

研究者Claudia Wellbrock表示,过去我们常常认为癌细胞是通过特异性侵袭到机体其它组织中来进行扩散,但是本文研究中我们却发现黑色素瘤细胞可以通过互相合作的侵袭模式来进行扩散;不同类型的癌细胞可以同时在肿瘤组织中存在,而且可以通过互相协作来进行高效扩散,这对于后期我们开发治疗性的策略往往具有一定的指示意义。

黑色素瘤是一种恶性的皮肤癌,在英国每年大约有1.33万人被诊断患有该疾病;而令人比较担忧的是近些年来恶性黑色素瘤的发病率相比20世纪70年代增加了超过5倍;研究者Richard Marais教授说道,恶性黑色素瘤是一种恶性的皮肤癌,其通常可以快速扩散并且引发恶性病变,这项研究就揭示了恶性黑色素瘤高效快速扩散的分子机制;近些年来随着恶性黑色素瘤有效疗法的开发,相信在不久的将来我们就可以成功治疗该疾病,当然平时我们也需要加强早期黑色素瘤的诊断,以早日预防黑色素瘤的产生。

阿司匹林防癌吗?保护DNA 防肿瘤细胞突变

目前医学界对于阿司匹林防癌的共识是,在进一步推广之前,有这么几个问题需要明确回答:应当在什么年龄服用,服用年限是多久,剂量如何控制?自1897年问世以来,阿司匹林的传奇就从未完结。若以50mg药片计算,全球每年消耗阿司匹林将超过1000亿片,无怪乎它在1950年就以“销量最高的药物”入选了吉尼斯世界纪录。在西方电影和小说中,酒后一片阿司匹林简直成为了硬汉的一种标志。这种消炎镇痛的白色药片,脱胎

ASCO2013:利用循环肿瘤细胞可检测Etirinotecan pegol治疗转移性乳腺癌的相关药效

背景:Etirinotecan pegol (EP)为一种独特的拓扑异构酶1抑制剂,可促进对SN38的持续接触。转移性乳腺癌(mBC)患者通过EP可获得29%的总缓解率,在此基础上又针对mBC患者进行了一项全球性临床III期BEACON试验。借助于患者血样中的循环肿瘤细胞(CTC)这一最低侵袭性的方式,可实现对与药物活性相关的药效学(PD) 标记物进行检测。本研究针对在治疗前后分离到的CTC建立了

Nat Commun:以非分裂肿瘤细胞为药物作用目标

本期Nature Communications上发表的一项研究,报告了优先以非分裂结肠癌细胞(它们经常对化疗药物有抵抗力)为目标的一种药物。虽然该研究证明这种药物对小鼠有效,但这些发现可能也可帮助开发治疗人类结肠癌的类似策略。 静止的或非分裂的细胞常见于肿瘤上血管形成状况较差的、营养状况较差的区域。这些细胞对传统化疗药物经常有抵抗力,而且如果不治疗的话还会导致二次肿瘤生长。Stig Li

近日,刊登在国际杂志Nature Materials上的一篇研究论文中,来自加州大学圣巴巴拉分校的研究人员通过研究设计出了一种新型的球状纳米颗粒,其主要由银组成,球状表面包被着一层肽,可以使其对肿瘤细胞进行靶向作用;这种新型纳米颗粒的外壳和内容物并不可拆分,因此不能靶向攻击肿瘤细胞的纳米颗粒就不会被消除和破坏掉。移除不能渗透靶向细胞的纳米颗粒的方法是特殊的,研究者Braun说道,通过对那些可以进入

在2013年7月14日在线出版的《肿瘤学年鉴》(Annals of Oncology)杂志上,发表了中国军事医学科学院江泽飞教授等人的一项研究成果,该项多中心、双盲、前瞻性研究针对中国转移性乳腺癌(MBC)女性患者,旨在评价循环肿瘤细胞(CTC)测定在预测抗癌治疗手段缓解率方面的潜在应用价值,其中包括人表皮生长因子受体-2(HER-2)靶向药物相关缓解情况、无进展生存期(PFS)以及总生存期(OS

JCB:FAK帮助肿瘤细胞越狱

癌细胞都是越狱的高手,现在加州大学Moores癌症中心的科学家们揭示了它们的秘诀。研究显示,一种促进肿瘤生长的关键蛋白,可以帮助癌细胞突破组织的囚禁。文章发表在Journal of Cell Biology杂志上。 肿瘤细胞形成之后会受到周围组织的限制,只有进入血液或者淋巴管,才能转移到其他部位。研究显示,生长因子VEGF可以帮助肿瘤细胞,松开血管壁内皮细胞之间的联系
