Expression Profiles of Estrogen-Regulated MicroRNAs in Breast Cancer Cells

Methods Mol Biol. 2016:1366:373-393. doi: 10.1007/978-1-4939-3127-9_30.

Abstract

Molecular signaling through both estrogen and microRNAs are critical for breast cancer development and growth. The activity of estrogen is mediated by transcription factors, the estrogen receptors. Here we describe a method for robust characterization of estrogen-regulated microRNA profiles. The method details how to prepare cells for optimal estrogen response, directions for estrogen treatment, RNA extraction, microRNA large-scale profiling, and subsequent confirmations.

Keywords: Breast cancer; Estrogen; Estrogen receptor; MicroRNA; Microarray; qPCR.
