概括

这项研究揭示了癌进展期间的关键细菌和基因变化. 识别这些标记物有助于区分可能成为癌症的高度病变.

科学领域:

胃肠道学和瘤学
微生物学微生物学
分子生物学分子生物学

背景情况:

部平细胞癌 (ASCC) 是一种罕见的癌症,与高风险的人类乳头瘤病毒 (HPV) 感染有关.
在艾滋病毒感染者中,ASCC的发病率较高,并从前体病变 (如高度状内皮病变 (HGSILs)) 发展起.

研究的目的:

调查从状内皮层病变到ASCC的进展过程中的转录和元转录变化.
为了确定癌进展的潜在诊断或治疗生物标志物.

主要方法:

对从前体病变到ASCC的样本进行了转录和元转录分析.
使用无监督集群分析基于分子和临床特征的样本异质性.

主要成果:

特定的细菌物种,包括Fusobacterium nucleatum和Bacteroides fragilis,在ASCC中比癌前病变更为丰富.
这些细菌与特定的宿主基因和coproteins (例如,Fada,dnaK) 相相关,这表明它们在ASCC发展中的作用.
转录组分析揭示了与组织学等级,免疫状况,HIV/HPV联合感染和通路活性相关的明显集群,反映了癌的自然史.

结论:

该研究确定了导致癌进展的分子机制.
这些发现有助于根据HGSIL病例进展到恶性瘤的风险进行分层,这可能有助于改善患者管理.

MicroRNAs

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
