Dr. Peiying Yu obtained her degree in Medicine from the University of Beijing Medical University in China. She had excellent research training at the Columbia University and New York State Psychiatric Institute where she was involved in the development and characterization of mouse monoclonal antibodies against serotonin receptors found in rat brain, specifically in the raphe nuclei.
Dr. Yu’s research interest centers on dopamine D1 receptor (D1R) regulation of signal transduction in lipid rafts in renal epithelial cells by elucidating the regulatory mechanisms involved in how these receptors control the oxidant and antioxidant systems to maintain homeostasis. Dr. Yu was first to demonstrate the mechanisms by which the D1R is regulated in LRs in human embryonic kidney (HEK-293) cells heterologously expressing and in rat renal proximal tubule cells (RPTCs). Dr. Yu has intensively studied how the various NAPDH oxidase subunits behave in lipid and non-lipid rafts in RPTCs and described the salient differences in their activity between human and rodent renal proximal tubule cells. She was first to describe that lipid rafts maintain NADPH oxidase in an inactive state in human RPTCs, in contrast to rodent RPTCs where NADPH oxidase is basally active in the lipid rafts. Lipid rafts serve as signaling platforms that spatially concentrate receptors and signaling molecules in order to facilitate and augment their interaction, thereby enhancing the efficiency and specificity of the signal transduction. At present, Dr. Yu is working on several aspects of D1-like dopamine receptor signaling to compare and contrast the mechanisms by which the D1R and D5R differentially regulate the various adenylyl cyclases, protein kinase C (PKC), and small G proteins in lipid vs. non-lipid rafts of human renal epithelial cells.
Dr. Yu has published over 30 peer-reviewed papers, including an invited methods paper on detailing the various protocols for the extraction of lipid rafts from different cell lines. Dr. Yu has expertise on immunohistochemistry, immunofluorescence, and confocal microscopy and remains to be a well-liked mentor to many post-doctoral fellows and new faculty.
