对TARGET数据集 (n=1025) 分析NID1表达与无事件生存 (EFS) 和KMT2A重排的相关性.
药物反应概况和RNA测序的NID1淘汰模型.

主要成果:

尼多根-1 (NID1) 被确定在儿科AML乳腺癌小细胞和骨髓母细胞中表达高,但在健康的造血干细胞中表达不高.
在小儿AML患者中,NID1表达与EFS和KMT2A重组的恶化显著相关.
NID1倒置模型显示对HSP90抑制的敏感性发生变化,NID1的高表达与LCS特征的线粒体代谢途径有关.

结论:

尼多根-1 (NID1) 是儿科AML的一个新型瘤基因,与EFS差和代谢性LSC表型相关.
NID1代表了风险分层的潜在生物标志物和治疗目标,以打击儿科AML的高复发率.

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
