MCF-7 nuclear extract (Estradiol treated)
背景资料：MCF-7 nuclear extract (Estradiol treated) was prepared from cell cultures of the human MCF-7 breast adenocarcinoma cancer cell line. The MCF-7 cell line was originally derived from a pleural effusion of a 69-year old Caucasian woman with metastatic breast cancer. MCF-7 cells are the best characterized and most commonly utilized cell lines in in vitro breast cancer studies. The MCF-7 cell line has retained several characteristics that are particular to mammary epithelium, including the ability to grow as a monolayer, form domes, and respond to hormones. These cells also display a low metastatic potential, leading to the assumption that they represent an early epithelial adenocarcinoma phenotype. These characteristics make MCF-7 cells an ideal model system to study malignant progression in relation to breast cancer.
Like mammary epithelial cells, MCF-7 cells are sensitive to estrogen. These cells process estrogen, in the form of estradiol, via cytoplasmic estrogen receptors. Treatment of with estradiol induces a proliferative response by activating the expression of early and delayed hormone-responsive genes required for cell cycle progression. In addition, estradiol treatment of MCF-7 cells causes inhibition of apoptosis.
产品描述：
MCF-7 nuclear extract (Estradiol treated) is specifically recommended for studies related to breast cancer research.
产品应用：
MCF-7 nuclear extract (Estradiol treated) is supplied in Dilution Buffer (20 mM Hepes (pH 7.9), 100 mM KCl, 1 mM MgCl2, 20% glycerol, 0.5 mM PMSF and 0.5 mM DTT). Cells were cultured in medium supplemented with 1 nM E2 (estradiol) for 96 hours at 37°C immediately prior to harvesting.

关于5-hmC
5-hmC是近年来在动物组织中发现的，由胞嘧啶修饰而来。5-hmC在表观遗传学上的功能可能与5-甲基化胞嘧啶(5-mC)不同。尽管到现在为止还不确知其功能，有研究者猜测它在调控基因的表达与关闭过程中起着重要的作用。5-mC的发现让我们不得不重新评估DNA甲基信息，也不得不监测人类的健康组织和病理组织之间5-mC相对分布的差异。在EPI公司的MethylFlash技术之前，我们还没有发现任何直接的常规方法来检测5- hmC,以及区分5-hmC和5-mC
5-hmC 和 5-mC的区别
时下常用的DNA甲基化分析方法包括限制内切酶酶切和亚硫酸氢盐或MeDIP介导的MS-PCR和测序，这些技术都不适合用来检测5-hmC，因为它与5-mC事实上很难用这类方法区分开来。为了解决这个问题，EPIk研制了MethylFlash羟甲基化DNA定量试剂盒(荧光法)。本试剂盒提供了一种很经济的方法来检测5-羟甲基化胞嘧啶，并且区分5-hmC, 5-mC, 和 C，使得研究者能够重新评估他们的DNA甲基化信息，也能够在新样品中寻找DNA羟甲基化。 |
