Next Generation RNA Sequencing Analysis Reveals Expression of a Transient EMT Profile During Early Organization of MCF10A Cells in 3D.

RNA sequencing is a technique widely used to identify and characterize gene expression patterns. We demonstrate that this method can be applied to screen expression profiles in mammary epithelial cells cultured in 3D, supported by a natural laminin-rich extracellular matrix, but requires several specific steps in the preparation of the RNA samples. Here we describe the use of RNA sequencing to analyze mRNA patterns in MCF10A human mammary epithelial cells cultured under 3D conditions in a laminin-rich extracellular matrix.

Systems biology-embedded target validation: improving efficacy in drug discovery.

The pharmaceutical industry is faced with a range of challenges with the ever-escalating costs of drug development and a drying out of drug pipelines. By harnessing advances in -omics technologies and moving away from the standard, reductionist model of drug discovery, there is significant potential to reduce costs and improve efficacy. Embedding systems biology approaches in drug discovery, which seek to investigate underlying molecular mechanisms of potential drug targets in a network context, will reduce attrition rates by earlier target validation and the introduction of novel targets into the currently stagnant market.
