概括

早期发病的乳腺癌 (BC) 正在随着分娩延迟而增加. 通过自上次出生以来的时间 (TSLB) 和蛋白质生物标志物识别出一种独特的产后BC亚型 (PPBC),这表明了新的预防和治疗目标.

科学领域:

在瘤学瘤学.
免疫学免疫学免疫学
基因组学就是基因组学.

背景情况:

早期发病的乳腺癌 (BC) 发病率上升与分娩延迟相关.
一种潜在的独特的产后BC (PPBC) 亚型可能解释了这一趋势,其特点是自上次出生以来的时间 (TSLB) 和特定的生物标志物.

研究的目的:

调查TSLB与早期发病的BC中的蛋白质表达之间的关联.
根据TSLB和生物标志物概况确定一个独特的PPBC表型.

主要方法:

使用GeoMx数字空间分析 (DSP) 来分析640BC样本中的71种蛋白质,这些样本来自40岁以下的女性.
应用了单变线性回归和多变量切片逆回归来评估与TSLB相关的生物标志物.
用OPAL多重免疫光测试和TCGA数据进行验证和相关性分析.

主要成果:

特定的蛋白质 (例如,PR,PTEN,GZMB,SMA,NF-1,纤维素,泛Akt) 在不同的BC组件中显示出与TSLB的显著关联.
在TSLB最短的女性中,PR,PTEN和CD20的关联是最强的.
与TSLB相关的蛋白质相关的RNA物种与与不良预后相关的T细胞枯竭特征相关.

结论:

这些发现支持PPBC作为由TSLB和生物标志物概况定义的生物学连贯的表型.
这种PPBC表型对早期乳腺癌的预防和向治疗有潜在的影响.

Tumor Progression

Tumor Progression

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...
