背景情况:

肝母细胞瘤 (HB) 是最常见的儿科肝脏瘤,由于其高复发率和转移率,它带来了重大治疗挑战.
伊诺辛单酸脱酶2 (IMPDH2) 在HB进展中的作用及其临床意义仍然不完全理解.

研究的目的:

研究IMPDH2在肝细胞瘤中的表达和临床影响.
评估IMPDH2作为潜在的预后生物标志物和HB的治疗点.

主要方法:

使用定量实时聚合酶链反应 (qRT-PCR) 和组织微阵列 (TMA) 来评估IMPDH2的表达.
在IMPDH2抑制后进行了包括流细胞计在内的体外测试,以分析细胞增殖,细胞亡和细胞周期.
研究了mycophenolate mofetil (MMF) 和 doxorubicin (DOX) 的协同作用.

主要成果:

在HB组织中,IMPDH2显著过度表达,与总体存活率 (OS) 和无事件存活率 (EFS) 的降低相关.
IMPDH2的上调与先进的临床病理特征有关,包括高AFP水平,转移和PRETEXT分期.
IMPDH2 knockdown 抑制了 HB 细胞的增殖和瘤性,导致 G0/G1 细胞周期停止. 与MMF和DOX的联合治疗增强了治疗反应.

Inhibition of Cdk Activity

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

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...
