Project description:Detailed knowledge of cell surface proteins for isolating well-defined populations of human pluripotent stem cells (hPSCs) would significantly enhance their characterization and translational potential. Normal H9 human embryonic stem cells and the KB3 human induced pluripotent stem cell lines were analyzed by Cell Surface Capture Technology, and in parallel transcript profiles from five independent samples (i.e., Replicas 1-5 for each) were performed to facilitate protein and transcriptomic comparisons. The study compared gene expression profiles of pluripotent stem cells with Cell Surface Capture technology generated N-glycoprotein surfaceome analyses of the same cell types.
Project description:Using the Cell Surface Capture Technology, the cell surface N-glycoproteomes of three cell lines and one in vitro differentiated cell type representing distinct cell fates and stages in mouse embryogenesis were assessed.

Project description:Secreted proteins and transmembrane proteins with extracellular domains are frequently glycosylated; this group of proteins includes those that participate in the various intercellular junctions and signaling pathways of an epithelium. In this study we characterized the differences in glycoprotein expression between claudin-low and other breast cell lines using a dataset of 26 breast cell lines in which the glycoproteins were identified and quantitated by liquid chromatography/ tandem mass spectrometry. Our goals are to characterize the glycoproteome of a set of claudin-low lines, compare them to basal, luminal and non-malignant cells and to identify drugs that may be especially effective on these cell lines. These seven luminal malignant breast cells (BT474, HCC1428, MCF7, SKBR3, SUM185PE, T47D and ZR751) data are a part of 26 breast cell lines we analyzed.

Project description:Fentanyl enhanced expression of CXCR4 and CCR5 protein levels and viral expression in a dose-dependent manner in multiple HIV-susceptible and HIV-infected cell lines. Multiple genes associated with apoptosis, antiviral / interferon response, chemokine. signaling, and NFκB signaling were differentially regulated by fentanyl. Thus fentanyl impacts HIV replication and chemokine co-receptor expression in HIV-susceptible and HIV-infected lymphocyte cell lines suggesting that opioid use may increase the likelihood of transmission to others and accelerate disease progression.
