Characterization Of Hcmv-Encoded Chemokine Receptor Us28 Transduced Msu1.1 Human Fibroblast Cells, Danielle R. Vanbeckum

All NMU Master's Theses

Human Cytomegalovirus (HCMV) encodes the G-protein coupled receptor US28. Using a mouse model system, US28 was previously found to be oncomodulatory, increasing proliferation, inducing anchorage independent growth and loss of contact inhibition. Similarly, in the human glioblastoma cell line U373, US28 activated VEGF expression. To determine if US28 is oncomodulatory in normal human cells, we engineered the human fibroblast cell line MSU1.1 to express US28 via lentivirus infection. MSU1.1 cells were transduced with pHAGE-US28-ZsGreen. Fluorescent confocal microscopy was utilized to detect the ZsGreen tag and confirmed the successful transduction of MSU1.1 cells with the US28 vector or empty pHAGE vector. …
