ABSTRACT: In order to understand the transcriptional effects of CD44s expression in a cell line that does not express CD44 in its native form we transfected CD44s into HEK cells and measured the transcriptional chances compared to native HEK cells
Project description:In order to understand the transcriptional effects of CD44s expression in a cell line that does not express CD44 in its native form we transfected CD44s into HEK cells and measured the transcriptional chances compared to native HEK cells Three biological replicates from each condition (native HEK cells and CD44s transfected cells) were measured using Affymetrix arrays
Project description:HEK-Blue™ ISG Cells and HEK-Blue™ ISG-KO-STING Cells (Invivogen) were transfected with dacA (Listeria monocytogenes) for 12 and 24 hours. Through this approach, we described the STING-dependent and STING-independent transcriptional response to dacA. Our analysis reveals a STING-dependent enrichment of interferon stimulated genes beginning 12 hours post-transfection, and a STING-independent enrichment of genes associated with protein translation and oxidative phosphorylation.
Project description:In order to evaluate the effects of RIZ2 overexpression on gene expression, a pilot expression study was performed through microarrays analysis. We compared the differential gene expression between HEK-293 cells overexpressing human RIZ2 (pEGFP-hRIZ2) and rat RIZ1 (pEGFP-rRIZ1) versus control cells transfected with the E-GFP empty vector alone (pEGFP).
Project description:The discovery of Toll-like receptors (TLRs) represented a significant breakthrough that paved the way for the study of host-pathogen interactions in innate immunity. However, there are still major gaps in understanding TLR function, especially the early dynamics of downstream TLR pathways remains less clear. We characterize a label-free optical biosensor-based assay as a powerful method to detect TLR activation in a native and label-free environment and to delineate the dynamics of TLR pathway activation. To gain a deeper insight into the biological processes underlying the ligand-specific signal traces of different LPS chemotypes in various cell types, RNA-seq analysis of transcriptional changes in HEK Blue hTLR4 reporter cells was performed. After 3 hours of stimulation with LPS E. coli or LPS S. minnesota, HEK Blue hTLR4 reporter cells showed significant changes in RNA expression compared to the unstimulated control.
Project description:HEK 293 cells were transiently transfected with plasmids expressing Vector only(PCMV), Aire, or MBD-VP16 with the goal of comparing the global gene expression profiles in the Aire and MBD-VP16 groups We used microarrays to detail the global gene expression profile.
Project description:To identify a novel lncRNA regulated by mutp53. Wtp53 and 5 different hotspots mutation of p53 were transiently transfected into HEK-293T cells and compared with plasmid vector (pcDNA6A-Flag).
Project description:HEK 293 cells were transiently transfected with plasmids expressing Vector only(PCMV), Aire, or MBD-VP16 with the goal of comparing the global gene expression profiles in the Aire and MBD-VP16 groups We used microarrays to detail the global gene expression profile. HEK 293 cells were transiently transfected with plasmids expressing Vector only(PCMV), Aire, or MBD-VP16 and 72 hrs post transfection total RNA was collected for microarray analysis.
