Notch Intracellular Domain Plasmid Delivery via Poly(lactic-co-glycolic acid) Nanoparticles to Upregulate Notch Signaling
Abstract Notch signaling is a highly conserved signaling system that is required for embryonic development and regeneration of organs. When the signal is lost, maldevelopment occurs and leads to a lethal state. Liposomes and retroviruses are most commonly used to deliver genetic material to cells. However, there are many drawbacks to these systems such as increased toxicity, nonspecific delivery, short half-life, and stability after formulation. We utilized the negatively charged and FDA approved polymer poly(lactic-co-glycolic acid) to encapsulate Notch Intracellular Domain-containing plasmid in nanoparticles. In this study, we show that primary human umbilical vein endothelial cells readily uptake the nanoparticles with and without specific antibody targets. We demonstrated that our nanoparticles also are nontoxic, stable over time, and compatible with blood. We also determined that we can successfully transfect primary human umbilical vein endothelial cells (HUVECs) with our nanoparticles in static and dynamic environments. Lastly, we elucidated that our transfection upregulates the downstream genes of Notch signaling, indicating that the payload was viable and successfully altered the genetic downstream effects..
