Project description:Bisphenol A (BPA) is an environmental endocrine disruptor which has been detected in almost all human bodies. Many studies have implied that BPA exposure is harmful to human health. Previous studies mainly focused on BPA effects on ER-positive cells. Genome-wide impact of BPA on gene regulation in ER-negative cells is unclear. In the present study, we performed RNA-seq to characterize BPA-induced gene regulation on ER-negative HEK 293 cells.
Project description:PBDEs are widely used in consumer and household products as flame retardants. Many studies have shown that PBDEs could disrupt thyroid hormone homeostasis and adversely affect brain development. Here, we explored the toxical effects of BDE209 on HEK 293 cells and found that BDE209 may have a role in nucleosome remodeling. Many gene sets involved in cancer are enriched at the BDE209-treated sample. This indicates the carcinogenicity of BDE209. Interestingly, the impacts of BDE209 dissoved in DMSO on gene expression are more pronounced than the simple additive effects of BDE209 and DMSO alone. Gene expression profiles of human embryonic kidney 293 cells (HEK 293) cultured in normal medium, and medium containing BDE209 or DMSO were generated by deep sequencing, using Illumina HighSeq2000, respectively..

Project description:HEK 293 cells were treated with 7.5 μM methylmercury (HgMe) for 48 h. Metabolites were extracted and subjected to LC-HRMS based metabolomics. LC-HRMS data were processed by SIEVE2.2 software. Metabolites associated with HgMe toxicity were screened and identified.
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: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:This work describes the alteration in the expression of genes in response to quinolinol treatment, we noticed an enrichment in the HEK 293 YAP/TAZ signature
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.
