概括

在肝细胞癌 (HCC) 细胞中失去氨酸拉链状后翻译调节剂1 (LZTR1) 促进了上皮-介质细胞可塑性 (EMP). 这种分子转移会损害细胞迁移和入侵,为HCC提供新的治疗点.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
细胞生物学细胞生物学

背景情况:

肝细胞癌 (HCC) 是癌症死亡的主要原因.
了解HCC细胞行为的分子调节者至关重要.
氨酸拉链状后翻译调节器1 (LZTR1) 影响RAS/MAPK信号传递,但其在HCC转录中的作用尚不清楚.

研究的目的:

研究LZTR1损失如何影响HCC中的信号传递,转录和细胞表型.
确定LZTR1缺乏在Hep3B HCC细胞中的分子和功能后果.

主要方法:

建立了一个LZTR1淘汰赛 (KO) Hep3B细胞模型.
使用途径分析,全转录组RNA测序 (RNA-Seq) 和qRT-PCR.
进行了功能性检测,包括伤口关闭,通井迁移和入侵.

主要成果:

LZTR1 KO细胞显示RAF-MEK-ERK-RSK信号的增加.
RNA-Seq确定了差异表达的基因,EMT基因组在控制细胞中得到丰富.
损失LZTR1诱导了杂交的上皮层-介质细胞表型,抑制了维丁,并损害了细胞迁移和入侵.

结论:

在HCC细胞中LZTR1缺陷驱动了上皮层-介质细胞可塑性 (EMP) 状态.
这种EMP状态的特点是信号改变和抑制的Vimentin.
失去LZTR1会重塑HCC细胞的行为,影响迁移和入侵.

关键词:

一个LZTR1一个LZTR1 在 RAS/MAPK 信号中.在RNA测序过程中,RNA测序在Vimentin中,使用了Vimentin.皮质介质酶体的可塑性基因组编辑基因组编辑肝细胞癌是肝细胞癌.

Loss of Tumor Suppressor Gene Functions

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
