研究人员说，重要的是，本文提供了一种机制，可能解释人类癌症中的基因形式如何变化。因而，这将对于今后确定BIR是否能够导致基团簇突变形成的研究很重要。如果这被证明是真实的，这可能对与开发癌症的治疗方法产生一个新的靶标。
多形性胶质母细胞瘤或GBM是成年人中的zui常见且具有侵袭性的脑肿瘤。多年来，该肿瘤细胞被认为局限于脑部，但由Carolin Müller 及其同事所做的一项新的研究发现，高达20%的GBM患者在其血液中也有循环肿瘤细胞。这一发现可解释为什么那些从罹患GBM者那里接受抗原抗体的人会在移植后在脑部以外出现肿瘤。而它可能表明是GBM患者在成为器官捐赠者之前进行筛检的一种方法。
Müller 及其同事发现，从GBM患者血液中所取样的循环肿瘤细胞要比在这些病人中预计发现的颅外肿瘤数多得多。他们没有发现对颅脑肿瘤动手术会增加肿瘤细胞在其它地方循环的任何证据。
在一篇相关的《焦点》文章中，Lara Perryman和Janine Erler提出，对GBM患者血液做循环肿瘤细胞筛检可帮助确定哪些病人可能成为合适的器官捐赠者。他们提示，这些循环细胞还可被用作一种监测该脑肿瘤进展与治疗的新方法。
多数细胞不能分裂，除非有足够的氧气存在以支持它们的后代，但是某些癌细胞和其他细胞类型规避了这个规则。现在，美国约翰霍普金斯大学的研究人员鉴定出废除细胞警告信号的机制，使得癌细胞能够继续分裂即使在没有强大的血液供给条件下。在这个过程中，研究人员发现溶酶体——细胞的蛋白质‘重复利用中心’——帮助控制细胞分裂的决定。他们还发现了新的证据表明某些药物能够停止肿瘤的生长，具有高水平的蛋白HIF-1α。

Importantly, the researchers say that this article provides a mechanism that might explain how the genetic form in human cancers changes. Thus, this will be important for future studies to determine whether BIR can result in the formation of cluster mutations. If this proves to be true, this may create a new target for the development of cancer therapies.
Glioblastoma multiforme or GBM is the most common and aggressive brain tumor in adults. For years, the tumor cells were thought to be confined to the brain, but a new study by Carolin Müller and colleagues found that as many as 20% of GBM patients have circulating tumor cells in their blood. This finding explains why people who receive antigen antibodies from people with GBM develop tumors outside the brain after transplantation. And it may indicate a way for GBM patients to screen before they become organ donors.
Müller and colleagues found that circulating tumor cells sampled from the blood of GBM patients were much more numerous than the extracranial tumors expected to be found in these patients. They found no evidence that cranial brain surgery would increase the circulation of tumor cells elsewhere.
In a related Focus article, Lara Perryman and Janine Erler suggest that circulating tumor cell screening of GBM patients' blood can help determine which patients may be suitable organ donors. They suggest that these circulating cells may also be used as a new method of monitoring the progress and treatment of this brain tumor.
Most cells can not divide unless certain oxygen is present to support their offspring, but some cancers and other cell types circumvent this rule. Now, researchers at Johns Hopkins University in the United States have identified a mechanism to abolish cellular warning signals so that cancer cells can continue dividing even without a strong blood supply. In the process, researchers found that lysosomes - the cellular protein 'recycle center' - helped to control cell division. They also found new evidence that certain drugs stop tumor growth and have high levels of protein HIF-1α.
