This understanding can be built by analyzing and synthesizing biological data; such as transcriptomic (gene expression), proteomic (protein levels), or metabolomic (metabolite levels). This thesis describes a streamlined workflow for analyzing transcriptomic data. This streamlined workflow not only reduced the barrier to conducting the analysis but also reduced the analysis cycle time. With the use of this workflow, a number of historical Amgen microarray datasets were mined to identify gene expression signatures indicative of productivity. The result of this mining identified key biological pathways specific to a highly productive Amgen cell line. This work suggests that these pathways are critical to heightened levels of protein production. Using this information to engineer future cell lines could enable Amgen to improve cellular protein production by over 30%, impacting costs associated with drug substance manufacturing. More broadly, this example of streamlining and standardizing transcriptomic data provides a framework for how Amgen Process Development can leverage biological data to improve CHO systems understanding and achieve operational impacts. === by Kerry Rachel Weinberg. === M.B.A. === S.M. in Engineering Systems
