概括

神经皮质细胞转化基因1 (NET1) 在许多癌症中表达高,与预后不佳相关,并促进瘤进展. 向NET1可能为各种癌症提供新的治疗策略,包括三阴性乳腺癌.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
遗传学是一个遗传学.

背景情况:

神经皮质细胞转化基因1 (NET1) 是一种关氨酸核酸交换因子,参与细胞调节.
NET1在癌症进展中的作用已在胰腺癌,胃癌和肝癌中得到证实,但其更广泛的功能尚未得到充分研究.
了解NET1的综合作用对于了解癌症转移至关重要.

研究的目的:

综合分析NET1在各种癌症类型中的作用和预后价值.
研究NET1对癌症进展和转移的贡献背后的分子机制.
探索NET1与临床特征,遗传改变和免疫微环境的关系.

主要方法:

利用癌症基因组图集 (TCGA) 和基因型-组织表达 (GTEx) 数据库进行差异表达分析.
使用日志等级测试和考克斯回归模型进行预后值评估.
分析了遗传变化,与临床特征的相关性,瘤基因,表观遗传修饰,瘤突变负担 (TMB),微卫星不稳定性 (MSI),干细胞分数,免疫细胞透和药物敏感性.

主要成果:

在18种瘤类型中,NET1的升高调节,高表达与LIHC,LUSC,PAAD和BRCA的预后不佳有关.
在LIHC,LUSC,PAAD和BRCA中,NET1放大是常见的,与副本数量的变化正相关.
在某些瘤中,NET1表达与表观遗传修饰和瘤基因以及TMB,MSI,DNAss和RNAss正相关.
NET1表达与自然杀手细胞和M1巨细胞有负相关性,但与免疫基因有正相关性,并且主要表达在瘤细胞中.
NET1过度表达促进了三阴性乳腺癌 (TNBC) 细胞的增殖,入侵和改变细胞周期/亡,可能通过AKT通路.

结论:

NET1是LIHC,LUSC,PAAD,BRCA和TNBC的潜在预后标志物. 这是一个很好的例子.
NET1过度表达驱动TNBC的恶性进展,可能通过AKT信号通路.
向NET1是一个有希望的治疗策略,可以抑制瘤的进展,克服免疫抑制的微环境.

The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
