Novel Approaches Towards Improved Purity In High Yield Transcription Reactions, Elvan Cavac
Doctoral Dissertations
High yields of RNA (e.g., mRNA, gRNA, lncRNA) are routinely prepared following a two-step approach: high yield in vitro transcription using T7 RNA polymerase, followed by extensive purification using gel or chromatic methods. In high yield transcription reactions, as RNA accumulates in solution, T7 RNA polymerase rebinds and extends the encoded RNA (using the RNA as a template), resulting in a product pool contaminated with longer than desired, (partially) double stranded impurities. Current purification methods often fail to fully eliminate these impurities which, if present in therapeutics, can stimulate the innate immune response with potentially fatal consequences. This study establishes …

A Microscale Approach To Investigate Breast Cancer Cellular Communication And Migration, Sharif Mohammad Mizanur Rahman
LSU Doctoral Dissertations
Metastatic breast cancer significantly decreases patient survival, with the majority of deaths caused by secondary metastasis. Cancer metastasis is a multi-step process that starts with the detachment of a cancer cell from the primary tumor and ends with establishing a secondary tumor at a distal location. This work's focus was to use an interdisciplinary microscale approach to study how cancer cells respond to neighboring cells and how they migrate in response to chemical gradients. Two distinct devices, a microfluidic device, and a 3D-printed plate insert, were developed to perform co-culture studies to elucidate the impact of ASCs on cancer cell …
