    • Transcription in mammalian cells can be assessed at a genome-wide level, but it has been difficult to reliably determine whether individual transcripts are derived from the Plus- or Minus-strands of chromosomes. This distinction can be critical for understanding the relationship between known transcripts (sense) and the complementary antisense transcripts that may regulate them. Here we describe a technique that can be used to (i) identify the DNA strand of origin for any particular RNA transcript and (ii) quantify the number of sense and antisense transcripts from expressed genes at a global level. We examined five different human cell types and in each case found evidence for antisense transcripts in 2900 to 6400 human genes. The distribution of antisense transcripts was distinct from that of sense transcripts, was non-random across the genome, and differed among cell types. Antisense transcripts thus appear to be a pervasive feature of human cells, suggesting that they are a fundamental component of gene regulation.
    • 哺乳动物细胞中的转录可以在全基因组范围内进行评估,但是难以可靠地确定个体转录本是否衍生自染色体的加号或阴影链。 这种区别对于了解已知转录物(有义)和可能调节它们的互补反义转录物之间的关系可能是至关重要的。 在这里,我们描述了一种可用于(i)识别任何特定RNA转录物的DNA链起源的技术,(ii)在全球范围内量化来自表达基因的正义和反义转录本的数量。 我们检查了五种不同的人类细胞类型,并且在每种情况下都发现2900至6400个人类基因中的反义转录物的证据。 反义转录物的分布与有义转录物的分布不同,在基因组中是非随机的,并且在细胞类型之间不同。 因此,反义转录物似乎是人类细胞的普遍特征,表明它们是基因调控的基本组成部分。

    • Current approaches for treating cancer are limited, in part, by the inability of drugs to affect the poorly vascularized regions of tumors. We have found that spores of anaerobic bacteria in combination with agents which interact with microtubules can cause the destruction of both the vascular and avascular compartments of tumors. Two classes of microtubule inhibitors were found to exert markedly different effects. Some agents that inhibited microtubule synthesis such as HTI-286 and vinorelbine, caused rapid, massive hemorrhagic necrosis when used in combination with spores. In contrast, agents that stabilized microtubules, such as the taxanes docetaxel and MAC-321, resulted in slow tumor regressions that killed most neoplastic cells. Remaining cells in the poorly perfused regions of tumors could be eradicated by sporulated bacteria Mechanistic studies showed that the microtubule destabilizers, but not the microtubule stabilizers, radically reduced blood flow to tumors, thereby enlarging the hypoxic niche in which spores could germinate. A single intravenous injection of spores plus selected microtubule-interacting agents was able to cause regressions of several tumors in the absence of excessive toxicity.
    • 目前用于治疗癌症的方法部分地由于药物不能影响肿瘤血管化程度差的区域而受到限制。 我们发现厌氧菌的孢子与微管相互作用的药物联合使用会导致肿瘤血管和血管腔的破坏。 发现两类微管抑制剂发挥显着不同的作用。 一些抑制微管合成的药物如HTI-286和长春瑞滨,当与孢子结合使用时会引起快速,大量的出血性坏死。 相反,稳定微管的药物,如紫杉类多西他赛和MAC-321,导致缓慢的肿瘤消退,从而杀死大多数肿瘤细胞。 机体研究表明,微管去稳定剂,但不是微管稳定剂,从根本上减少了血液流向肿瘤,从而扩大了孢子可能发芽的低氧生态位。 单次静脉注射孢子加选定的微管相互作用剂能够在没有过度毒性的情况下引起几种肿瘤的消退。
