Sci Rep:包含活性基质前列腺癌组织的代谢和转录组分析

2018-10-10 AlexYang MedSci原创

活性基质是一种组织特性,通常在前列腺癌的肿瘤微环境中观察到,并且与恶性肿瘤相关。最近,有研究人员在完全相同的前列腺癌组织样本中,检测了活性氧基质包含物中差异表达的基因和代谢物质。研究人员利用组织病理学评估了来自43名前列腺切除术后患者的108份冷冻的前列腺癌样本活性氧基质。研究人员在部分样本中利用高分辨率魔角旋转磁共振光谱(HR-MAS MRS)he RNA芯片分别分析了代谢物(n=85)和转录组

活性基质是一种组织特性,通常在前列腺癌的肿瘤微环境中观察到,并且与恶性肿瘤相关。最近,有研究人员在完全相同的前列腺癌组织样本中,检测了活性氧基质包含物中差异表达的基因和代谢物质。

研究人员利用组织病理学评估了来自43名前列腺切除术后患者的108份冷冻的前列腺癌样本活性氧基质。研究人员在部分样本中利用高分辨率魔角旋转磁共振光谱(HR-MAS MRS)he RNA芯片分别分析了代谢物(n=85)和转录组变异(n=78)情况。研究人员根据不少于5年的跟踪调查结果评估了无复发生存(n=38),并利用生化复发(BCR)作为终点,并利用多元代谢组学和基因表达分析比较了低(不大于15%)和高活性基质(不小于16%)包含物。研究发现,在前列腺癌患者的患者中,高活性基质包含物与BCR相关(Cox风险比例分析,p=0.013);且在考虑到等级组影响时结论一致。在具有高活性基质包含物中,与免疫功能和细胞外基质(ECM)重建有关的代谢物和基因均显著上调。

最后,研究人员指出,考虑到免疫机制和前列腺癌中的ECM,这些发现的进一步确定对阐释新的生物标记和药物靶标是重要的。另外,高活性基质分级与BCR有关,该事实进一步支持了组织病理学检查在临床整合中的必要性。
