- 遗传学 是一个遗传学.
背景情况:
- 阴阳1 (YY1) 是一种转录因子,参与表观遗传调节.
- CP2c充当瘤基因,促进细胞增殖.
- 已知YY1可以抑制CP2c的转录活性.
研究的目的:
- 研究乳腺癌中YY1和CP2c的表达.
- 为了确定YY1和CP2c表达的预后影响.
- 探索乳腺癌中YY1和CP2c之间的关系.
主要方法:
- 免疫组织化学染色,西部斑点和RT-PCR用于评估YY1和CP2c表达.
- 分析包括491名患有初级乳腺癌的患者.
- 随访数据收集时间中位数为68个月.
主要成果:
- 在491名患者中有138名患者观察到YY1过度表达,并与光线亚型和早期阶段有关.
- YY1过度表达与改善的无病存活率相关 (92.0%对比79.2%,p=0.014).
- YY1过度表达是一个独立的预后因素 (HR0.50,p=0.042) 并与CP2c蛋白水平负相关.

Tumor Progression
6.4K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Abnormal Proliferation
4.6K
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...
