Project description:This experiment was carried out to investigate the responses of the human liver model (HepG2) cells upon the exposure of various DILI compounds in multiple severity scenarios by varying the concentration. The cells were seeded in 384 well plate format containing 8000 cell per well with 2 days of resting before exposure. The compounds were exposed for 8 and 24 hours. The cells were lysed and the lysate was collected for high throughput targeted RNA-seq with the human whole genome library. The gene expression profiles were analyzed to identify the modulated responses of the cells. This experiment is part of the TransQST project.

The cells were seeded in 384 well plate format containing 8000 cell per well with 2 days of resting before exposure. The compounds were exposed for 4, 8, and 24 hours. The cells were lysed and the lysate was collected for high throughput targeted RNA-seq with the human whole genome library.

Project description:Recent studies have shown that Pelagibacter oxidize a wide range of one carbon (C1) and methylated compounds that are ubiquitous in the oceans. However, the metabolic pathways used to oxidize and assimilate these compounds are complex and have been only partly described. To understand the metabolism of these compounds in Pelagibacter and to identify candidate genes involved in these pathways, we used microarray to study changes in gene expression in response to five different compounds (trimethylamine N-oxide (TMAO), methylamine, dimethylsulfoniopropionate (DMSP), methanol, and glycine betaine (GBT)) in Pelagibacter strain HTCC1062. This project will examine the transcriptional response of the marine microorganism Pelagibacter HTCC1062 to five methylated compounds. To do this, 18 flasks were innoculated with cells - 3 flasks without any methylated compounds and rest of 15 treated with different methylated compounds respectively (TMAO (trtmA), methylamine (trtmB), DMSP (trtmC), methanol (trtmD) and glycine betaine (trtmE)). Cells were all harvested at the same timepoint in the exponential phase.
