Enrichment of Native Lipoprotein Particles with microRNA and Subsequent Determination of Their Absolute/Relative microRNA Content and Their Cellular Transfer Rate Markus Axmann1, Andreas Karner2, Sabine M. Meier1, Herbert Stangl1, Birgit Plochberger2 1Center for Pathobiochemistry and Genetics, Institute of Medical Chemistry and Pathobiochemistry, Medical University Vienna, 2School of Medical Engineering and Applied Social Sciences, University of Applied Sciences Upper Austria Here, a quantitative real-time polymerase chain reaction-based protocol is presented for the determination of the native micro-RNA content (absolute/relative) of lipoprotein particles. In addition, a method for increasing the micro-RNA level, as well as a method for determining the cellular uptake rate of lipoprotein particles, is demonstrated.
An In Ovo Model for Testing Insulin-mimetic Compounds Renate Haselgrübler*1, Flora Stübl*1, Verena Stadlbauer1,2, Peter Lanzerstorfer1, Julian Weghuber1,2 1University of Applied Sciences Upper Austria, 2Austrian Competence Center for Feed and Food Quality, Safety and Innovation In this study, we describe an in-ovo system as a promising tool to test insulin-mimetic compounds in a living organism. The main advantages include adequate throughput rates and acceptable costs, which enable the identification of phytochemicals with insulin-mimetic properties.
