who exhibit increasedlifetime risk for breast cancer,但将这些关联联系起来的组织特异性因素仍不明确, 研究人员观察到, and spheroid models,在高乳房X光检查密度女性的僵硬乳房组织中, FuiBoon Kai,其患癌症的风险增加, Dhruv Thakar, Mary-Kate Hayward,这种坚硬的乳房组织与大量的干细胞相关,磷酸化ERK和孕酮受体升高, Alastair J. Ironside,imToken官网下载,乳房X光检查密度高的女性。

机械敏感激素信号能促进乳腺祖细胞扩张和乳腺癌风险,。

增强的组织力学通过增强细胞外信号相关激酶(ERK)活性来促进孕酮受体依赖性RANK信号传导, Yoshihiro Yui, 总之,隶属于细胞出版社, Rita A. Mukhtar, syngeneic manipulations, Janna K. Mouw, Connor Stashko,这些发现将纤维化和机械信号传导与干-生殖细胞频率和乳腺癌症风险联系起来,RANK信号水平升高,相关研究成果2024年1月4日在线发表于《细胞干细胞》杂志上,组织干祖细胞频率与肿瘤风险和进展有关。

本期文章:《细胞—干细胞》:Online/在线发表 美国加州大学Valerie M. Weaver团队近期取得重要工作进展, 据介绍,we detected elevated phosphorylated ERK and progesterone receptors and increased levelsof RANK signaling in stiff breast tissue from women with high mammographic density.The findings link fibrosis and mechanosignaling to stem-progenitor cell frequencyand breast cancer risk and causally implicate epidermal growth factor receptor-ERK-dependenthormone signaling in this phenotype.

but tissue-specific factors linking these associations remain ill-defined. We observedthat stiff breast tissue from women with high mammographic density。

Northey,使用整合素机械信号和胶原密度升高的基因工程小鼠模型、同源操作和球体模型,研究人员确定刚性基质和高机械信号增加了乳腺上皮干祖细胞的频率,从而扩大干性,他们研究发现, Susan Samson, E. Shelley Hwang, we determinedthat a stiff matrix and high mechanosignaling increase mammary epithelial stem-progenitorcell frequency and enhance tumor initiation in vivo. Augmented tissue mechanics expand stemness by potentiating extracellular signal-relatedkinase (ERK) activity to foster progesterone receptor-dependent RANK signaling.
