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. Systems biology approaches also have the potential to assist in the design of multidrug treatments and repositioning of existing drugs, while stratifying patients to give a greater personalization of medical treatment.

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. We focus on our methods for total RNA extraction at early time points during the formation and maturation of 3D acinus structures in these cultures and provide examples of our results and downstream analysis.
Planning a symposium organized by PhD students is a challenging prospect. Insight from the organizers of three such symposia sheds light on the highs and lows of the experience.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
