Description:
AR Responsive Luciferase Reporter MDA-MB-453 Stable Cell Line is derived from human breast cancer, and stably express firefly luciferase reporter gene under the control of the AR response element. This cell line is an ideal cellular model for monitoring the activation of Androgen Receptor Pathway triggered by stimuli treatment, enforced gene expression and gene knockdown.Principle:
The androgen receptor (AR) plays a crucial role in the development of male reproductive organs. When activated by stimuli, AR translocates from the cytoplasm into the nucleus, which then binds a DNA recognition site and regulates gene expression. Signosis has established an AR luciferase reporter stable cell line, in which luciferase activity is specifically associated with the activity of AR. Therefore, the cell line can be used as a reporter system for monitoring the activation of AR triggered by stimuli treatment, enforced gene expression, and/or gene knockdown.
The cell line was established by transfection of an AR luciferase reporter vector along with G418 expression vector followed by G418 selection. The G418 resistant clones were subsequently screened for etoposide-induced luciferase activity. The clone with the highest fold induction (22 fold) was selected and expanded to produce this stable cell line.

Principle behind TF luciferase reporter. TF luciferase reporter stable cell line utilizes artificial promoter constructs to drive luciferase expression. The promoter region can consists of multiple repeats of a cis-element TF binding site, a DNA fragment from the promoter region of a known TF downstream gene, or a DNA fragment containing putative/known TF binding sites. There are several ways that a TF can be activated, such as through extracellular stimuli or through intracellular signaling pathways. Once activated, the TF translocates to the nucleus and often interacts with relevant co-factors to drive gene expression. Once luciferase is expressed, it can generate light in an enzymatic assay and the amount of light measured is positively correlated with the level of TF activation. |
Data:
Analysis of Androgen Receptor Pathway Reporter MDA-MB-453 Stable Cell Line in response to stimuli. The cells were seeded on a 96-well plate for overnight with DMEM including 10% FBS. The cells then were treated with or without 20nM DHT respectively in DMEM and 0.1% FBS for 16 hours.

至于到底好不好转就跟你的细胞有关了，和细胞是否是稳转株关系不大。
推荐了解“主细胞库”“工作细胞库”这两个名词。
推荐了解“主细胞库”“工作细胞库”这两个名词。
如果经费充足的话可以找公司包装病毒，如武汉的普健可以提供各种载体的构建及细胞株构建的技术服务。
然后你得确定，这个细胞株对于你得研究来说不可或缺，具有明确的代表性。
上面两个都没有问题的话，祝你顺利。
