摘要

发表在《自然》(Nature)上的一项新研究发现了一个在人类结直肠癌(CRC)生态位中占主导地位的独特的核团镰刀菌支系--Fna C2。重要的是,在小鼠体内,Fna C2 会导致大肠腺瘤数量增加和代谢物谱改变。研究人员从135株F.nucleatum菌株(80株来自非癌症患者的口腔菌株和55株从51名CRC患者的肿瘤中培养出的独特癌症菌株)中生成了封闭基因组,确定了483个富含CRC的遗传因子(相比之下,241个基因簇在口腔菌株中非常普遍)。此外,肿瘤分离菌株主要属于 F. nucleatum subsp. animalis,但进一步的泛基因组分析表明,该亚种实际上由两个不同的支系(Fna C1 和 Fna C2)组成。至关重要的是,Fna C2 支系富集于 CRC 龛位,而 Fna C1 支系则主要局限于口腔,并且与 C1 支系有明显的不同,包括存在额外的毒力因子(包括 fap2、cmpA 和 fusolisin)和不同的形态(Fna C2 细胞更长、更薄)。
