Cell cycle regulatory proteins Ki 67, cyclin A, and p27 are associated with cell proliferation. 背景与目的:研究表明肿瘤细胞周期分析显示细胞具高增殖率的肿瘤,其临床病情发展快;细胞周期调节蛋白Ki-67、细胞周期蛋白A及p27介入到细胞的增殖,但这些因子与食管癌之间的关系的研究在我国尚未见报道。 更多例句...
Ki-67 positive cells (brown nuclei) mediate the stem cell (SC) niche. Effective chemotherapy dramatically reduces Ki-67 expressing cells, which in turn leads to reduced or eradicated cancer stem cells. Ineffective chemotherapy may reduce the bulk population of cells, but the percentage of Ki-67...
Effects of UA and radiation on the percentage of Ki-67 positive cells.Yang YangMan JiangJing HuXin LvLixia YuXiaoping QianBaorui Liu
ki-67表达与vp中的40kev的ct值,有效原子序数,ic和λhu呈正相关. 高(≥80% positive cells) ,低 ( <80% positive cells ) ki-67表达的ic鉴别阈值为 1.035mg/ml sdct参数与crac中的her2表达之间没有显著相关性. 结论: sdct参数在评估结直肠腺...
Proliferation activity is determined as the ratio of Ki-67-positive cells (given as a percentage), commonly known as proliferation index (PI) (Eq. 1). $$PI={\frac{{N}_{Ki-67\left(+\right)}}{{N}_{Ki-67\left(+\right)}{+N}_{Ki-67\left(-\right)}}}x 100\%$$ (1) ...
(immunohistochemically quantified by determining the number of Ki67 positive cells among the total number of resting cells = Ki67 index). In neoplastic tissues the prognostic value is comparable to the tritiated thymidine labelling index. The correlation between low Ki67 index and histologically low ...
2 A monoclonal antibody is used for IHC staining of the proliferation-associated nuclear protein Ki-67 in tumor cells to determine the percentage of Ki-67–positive cells among the total population of tumor cells in formalin-fixed paraffin-embedded sections obtained from a core-cut biopsy sample;...
"ki-67 labeling index" refers to the number of ki-67 positive cells within the population and this is used to predict outcome of particular cancer types. ki-67 has been shown to interact with the dna-bound protein chromobox protein homolog 3 (cbx3) (heterochromatin). the sola15 antibody...

A) Ki-67 immunohistochemical staining of lung adenocarcinoma shows variable amounts of positive cells within the slide. Red line indicates the area of coverage inside the Spiral Array (bar = 5 mm). Both high expression area of Ki-67 (B) and low expression area of Ki-67 (C) are ...
