癌症生物学癌症生物学

背景情况:

扩散性大B细胞淋巴瘤 (DLBCL) 的预后因素已经得到充分确认.
有限的预后信息存在,特别是对于体积庞大的DLBCL患者.
体质量被定义为最大瘤直径≥7.5厘米.

研究的目的:

为了研究MYC蛋白表达在重质量DLBCL中的预后价值.
分析其他生物参数作为该患者队列的预后指标.

主要方法:

评估MYC蛋白质表达水平.
评估整体生存期 (OS) 和无进展生存期 (PFS).
基于国际预测指数 (IPI) 和安纳伯阶段的子组分析.
多变量分析对IPI进行调整.

主要成果:

MYC过度表达显着与更糟糕的OS (p=0.019) 和PFS (p=0.001) 有关.
在高IPI (3-5),高级阶段 (3-4) 和GCB亚型的亚组中观察到MYC过度表达患者的较差结果.

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...

Induced Pluripotent Stem Cells

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
