- 分子生物学分子生物学
背景情况:
- 子宫清细胞癌 (CCCC) 是一种非常罕见的子宫癌亚型.
- 组织因子通路抑制剂-2 (TFPI2) 表达在卵巢和子宫内膜透明细胞癌中得到了记录.
- 肝细胞核因子1本体B (HNF-1β) 是已知的卵巢清细胞癌的诊断标志物.
研究的目的:
- 为了调查TFPI2表达在宫癌,特别是CCCCC.
- 评估HNF-1β作为CCCCC的潜在诊断标记.
- 用免疫组织化学方法将CCCC与其他宫病理区分开来.
主要方法:

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
