细胞生物学细胞生物学
生物化学生物化学

背景情况:

前列腺癌 (PCa) 转移是一个重大的临床挑战.
了解PCa转移的分子驱动因素对于开发有效治疗方法至关重要.

研究的目的:

为了研究铁化,一个依赖铁的细胞死亡途径,在前列腺癌转移中的作用.
确定将铁灭调节与PCa转移潜力联系起来的分子机制.

主要方法:

使用了具有不同转移潜力的PC-3M细胞系 (PC-3M-1E8,高;PC-3M-2B4,低).
进行了功能性测试 (扩散,迁移,入侵,克隆性能力).
进行蛋白质组分析和基因组丰富分析 (GSEA),以确定关键途径和蛋白质.
在不同细胞系中验证了铁亡调节剂和敏感性.

主要成果:

高度转移的PC-3M-1E8细胞表现出增强的增殖,迁移,入侵和克隆性能力.
在高转移性细胞中,GSEA确定了铁化作为一种显著丰富的途径.
关键的铁灭细胞调节剂 (GPX4,GCLM,GCLC,TFRC) 在转移细胞中被上调,而其他 (ACSL4,VDAC3) 在转移细胞中被下调,表明铁灭细胞耐药性.
转移性细胞表现出显著更高的抵抗力对ferroptosis诱导.

结论:

在ferroptosis敏感性和前列腺癌转移潜力之间存在反向相关性.

Cancer Cell Migration through Invadopodia

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...
