Project description:Sequence analysis of IFNAR1 KO in HEK 293 cells (deletion)

Project description:We identified a new RhoE isoform, RhoEα, and compared the differentially regulated signalings by these two proteins. Both RhoE and RhoEα were first knocked out via CRISPR/Cas9 in HEK 293 cells and HeLa cells (KO cells), followed by RhoE and RhoEα reintroduction (RhoE reintroduction cells and RhoEα reintroduction cells, resepectively). Wild-type cells, KO cells, RhoE reintrocution cells, and RhoEα reintroduction cells were then subjected to RNA-seq analysis.

Project description:The aim of this study is to discover genes regulated by miR-204. Differential gene expression in HEK-293 cells transfected with miR-204-mimic compared to HEK-293 cells transfected with control oligo (HEK-293 control) was analyzed using the Agilent Human Whole Genome 4x44K gene expression array (Agilent Technologies, Santa Clara, CA).

Project description:We used high-throughput sequencing to investigate the genome-wide transcriptional response in human cells to treatment with Borrelia burgdorferi. We chose a time point of 72 h as ticks feed on their host for several days and at the same time the early response in Lyme disease is expected to occur at this time period at a cellular level. We found that the two cell models studied (HUVEC and HEK-293 cells) had significantly different responses. More significantly differentially expressed genes (69 in total) were found in HUVEC cells than in HEK-293 cells (8 in total). Functional analysis indicated induction of the immune response in HUVEC and suggest changes in the extracellular matrix in HEK-293.

Project description:To determine the target genes of RBM10,we have employed microarray based gene expression profiling by knocking down RBM10 in HEK 293 cells. Microarray analysis after RBM10 knockdown on HEK 293 cells showed that over 1000 genes were down regulated while another 800 genes up regulated as a result of the knockdown. Among the down regulated genes, we found the significant presence of cardiovascular disease related genes, especially cardiac hypertrophy and heart failure.

Project description:The aim of this study is to discover genes regulated by miR-204. Differential gene expression in HEK-293 cells transfected with miR-204-mimic compared to HEK-293 cells transfected with control oligo (HEK-293 control) was analyzed using the Agilent Human Whole Genome 4x44K gene expression array (Agilent Technologies, Santa Clara, CA). HEK-293 cells were transfected with either miR-204 or a control, and gene expression was analyzed using the Agilent Human Whole Genome 4x44K array. A dye-swap was performed.

Project description:Human embryonal kidney cells (HEK-293) are the most common host cells used for transient recombinant adeno-associated virus (rAAV) production in pharmaceutical industry. To better cover the expected gene therapy product demands in the future, different traditional strategies such as cell line sub-cloning and/or addition of chemical substances to the fermentation media have been used to maximize titers and improve product quality. A more effective and advanced approach to boost yield can be envisaged by characterizing the transcriptome of different HEK-293 cell line pedigrees with distinct rAAV productivity patterns to subsequently identify potential gene targets for cell engineering. In this work, the mRNA expression profile of three HEK-293 cell lines, resulting in various yields during a fermentation batch process for rAAV production, was investigated to gain basic insight into cell variability and eventually to identify genes that correlate with productivity. Mock runs using only transfection reagents were performed in parallel as a control. We found significant differences in gene regulatory behaviors between the three cell lines at different growth and production stages. The evaluation of these transcriptomics profiles combined with collected in-process control parameters and titers shed some light on potential cell engineering targets to maximize transient production of rAAV in HEK-293 cells Comparison of three HEK-293 suspension cell lines transcriptomics during an AAV production process

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.
