Open Biol:癌细胞如何在营养不良的状况下生长繁殖?

2018-05-10 佚名 细胞

癌症研究领域的其中一个秘密就是肿瘤细胞如何在血液和营养状况不良的情况下存活并且生长,近日,来自弗林德斯大学和纽卡斯尔大学的科学家们通过研究系统性地绘制了相关的核心基因图谱和生物学图谱来解释癌细胞如何在营养压力状况下得以生存并繁殖,相关研究刊登于国际杂志Open Biology上。

癌症研究领域的其中一个秘密就是肿瘤细胞如何在血液和营养状况不良的情况下存活并且生长,近日,来自弗林德斯大学和纽卡斯尔大学的科学家们通过研究系统性地绘制了相关的核心基因图谱和生物学图谱来解释癌细胞如何在营养压力状况下得以生存并繁殖,相关研究刊登于国际杂志Open Biology上。

文章中,研究人员提出了一套针对细胞和生物学过程的新型数据,其或许能够帮助调节癌细胞在不良营养状况下生存的能力特性,研究者利用高通量的筛选技术识别出了能够调节细胞适应性的关键基因,Petersen教授表示,对这些数据进行综合性收集及分析还能帮助其他研究人员寻找肿瘤生长的路径。

研究人员认为,在他们分析饥饿酵母菌的适应性和生存能力的过程所鉴别出的保守性基因,或能帮助其他研究人员理解这些细胞如何应对人类机体中的饥饿状况。对这些基因进行分析或能鉴别出大量特殊的生物学过程,包括染色质和转录调节、营养摄取及运输途径等,在这些过程中,研究人员发现,染色质组织-调节、横跨细胞膜以及囊泡介导的运输过程或许在促进细胞适应性上扮演着关键的角色;改变染色质的调节或许就能促进转录调节的改变,并且还能改变细胞中营养物质、铁和维生素的运输,从而帮助细胞更快地适应营养缺乏的状况,这就是实体瘤内部癌细胞的关键特征。

本文研究或能帮助研究人员理解在慢性或急性营养供给波动状况下细胞适应环境的分子机制,这或许是很多癌细胞形成的一种关键特性,当然研究人员也希望能够以此为靶点来开发出有效治疗多种类型癌症的新型疗法。

严重心衰5年生存率比癌症更低,专家呼吁加强认识和综合治疗

“近30年来,我国心衰的治疗情况已经有了很大改善,死亡率下降了60%-80%。但即便这样,严重心衰5年生存率甚至比恶性肿瘤更低。”上海市浦东新区浦南医院心血管内科主任于泓教授表示。为让浦东基层及二三级医院医护人员及时了解“心衰”领域诊治新进展,由于泓教授发起的“2018年浦南医院心衰综合治疗学习班”日前在浦东新区成功举办。学习班邀请沪上及日本知名心血管领域专家参与。于泓教授说,目前临床治疗心衰的

从10毫升血液中捕捉癌症突变!

有文献报道,晚期肺癌患者中有10%—15%的比例由于受到各种客观原因限制,无法进行穿刺活检,从而导致在对一代靶向药物产生耐药性后无法通过组织活检寻找后续治疗方案,这让患者身陷绝望的境地。不过现在只要采集10毫升的血液,就可以通过“液态活检”这一新型检测手段为这些患者找到出路,而这项技术也可用于其他癌症的监测治疗。

真的!维生素D可以帮你远离癌症风险

通常在我们的印象中,维生素D只与钙代谢以及骨骼健康密切相关。也许我们只会在人缺钙的时候才会想到去补充维生素D。但是你肯定想不到,血浆中维生素D水平的高低也与恶性肿瘤,特别是肝癌发生风险呈负相关。目前最新的体外研究和动物实验中已经证实,维生素D可以通过多种信号通路,比如细胞周期阻滞、细胞凋亡、血管生成和炎症抑制等多种信号通路抑制肿瘤的发生和发展。最近日本研究者,通过一项涉及14万人近20年的前瞻性队

我生活这么健康,竟然也得癌症?!

“为什么是我?”确诊肺癌后,我妈问了无数次。医生查房,她问:“是不是把别人的报告,错认是我的?我吃得下睡得着,怎么会是癌?”亲友团来探望,她叨叨:“XX烟不离嘴,天天棋牌室泡着。结果呢,人家长命百岁!我生病了!”同病相怜的患友们聊天,她很关心别人的生活起居:“侬抽烟伐?喝酒伐?……我的生活习惯也很好的!为什么是我们哦?”我最初以为,这个疑问和“天为什么是蓝色”、“人为什么要呼吸”、“为什么男人不能
