Abstract
OBJECTIVES:Polyploidy is a fascinating characteristic of liver parenchyma. Hepatocyte polyploidy depends on the DNA content of each nucleus (nuclear ploidy) and the number of nuclei per cell (cellular ploidy). Which role can be assigned to polyploidy during human hepatocellular carcinoma (HCC) development is still an open question. Here, we investigated whether a specific ploidy spectrum is associated with clinical and molecular features of HCC. DESIGN:Ploidy spectra were determined on surgically resected tissues from patients with HCC as well as healthy control tissues. To define ploidy profiles, a quantitative and qualitative in situ imaging approach was used on paraffin tissue liver sections. RESULTS:We first demonstrated that polyploid hepatocytes are the major components of human liver parenchyma, polyploidy being mainly cellular (binuclear hepatocytes). Across liver lobules, polyploid hepatocytes do not exhibit a specific zonation pattern. During liver tumorigenesis, cellular ploidy is drastically reduced; binuclear polyploid hepatocytes are barely present in HCC tumours. Remarkably, nuclear ploidy is specifically amplified in HCC tumours. In fact, nuclear ploidy is amplified in HCCs harbouring a low degree of differentiation and TP53 mutations. Finally, our results demonstrated that highly polyploid tumours are associated with a poor prognosis. CONCLUSIONS:Our results underline the importance of quantification of cellular and nuclear ploidy spectra during HCC tumorigenesis.
摘 要
目的: 多倍体是肝实质的一个迷人特征。肝细胞多倍体取决于每个细胞核的DNA含量 (核倍性) 和每个细胞的细胞核数量 (细胞倍性)。在人类肝细胞癌 (HCC) 发展过程中,多倍体的作用仍然是一个悬而未决的问题。在这里,我们研究了特定的倍体谱是否与HCC的临床和分子特征相关。 设计: 在HCC患者手术切除的组织以及健康对照组织上测定倍体谱。为了定义倍体谱,在石蜡组织肝脏切片上使用定量和定性原位成像方法。 结果: 我们首次证明多倍体肝细胞是人肝实质的主要成分,多倍体主要是细胞 (双核肝细胞)。跨肝小叶,多倍体肝细胞不表现出特定的分带模式。在肝脏肿瘤发生过程中,细胞倍体急剧减少; 双核多倍体肝细胞几乎不存在于HCC肿瘤中。值得注意的是,核倍体在HCC肿瘤中特异性扩增。事实上,在具有低分化程度和TP53 突变的hcc中,核倍体被扩增。最后,我们的结果表明,高度多倍体肿瘤与不良预后相关。 结论: 我们的结果强调了HCC肿瘤发生过程中细胞和核倍体谱定量的重要性。
