The aim of the dataset was to study on genome-wide level the effect of Notch inhibition in gene expression on neural crest differentiation of human embryonic stem cells under chemically defined conditions.
Notch signaling regulates the differentiation of neural crest from human pluripotent stem cells.

View SamplesWe extracted RNA from whole cells and RNA from the cytoplasm and performed RNA sequening to compare differences in gene expression level and investigate what is the most appropriate estimate of the amount of mRNA present in a given cell population. The study was based on three human cell lines. Overall design: Analyze of transcriptome in 3 human cell lines (U-2 OS, A-431, U-251MG). Each cell line was prepared with four biological replicates for total RNA and four for cytoplasmic RNA.
Comparison of total and cytoplasmic mRNA reveals global regulation by nuclear retention and miRNAs.

Little is known about the immune response to infection at the maternal-fetal interface and in the fetus itself, or the molecular events behind virus transmission and disease progression in the fetus. To investigate these processes, RNA-sequencing of two tissues, uterine endothelium adjacent to the umbilical attachment site and fetal thymus, was performed 21 days post challenge on four groups of fetuses selected from a large PRRSV challenge experiment of pregnant gilts. Overall design: RNA-seq experiment compared gene expression between four different groups of fetuses (n=12 per group): control (CON-uninfected fetuses from mock inoculated gilts), UNINF (uninfected fetuses from PRRSV-inoculated gilts), INF (infected fetuses from PRRSV-inoculated gilts), and meconium-stained fetuses (MEC-meconium-stained fetuses from PRRSV-inoculated gilts) and investigated two tissues: uterine endometrium (with adherent placental tissue) at the site of umbilical attachment and fetal thymus (96 samples in total). Three contrasts were performed for the differential expression (edgeR) and network (WGCNA) analyses: UNINF v CON, INF v UNINF, and MEC v INF.

View SamplesA first generation Affymetrix GeneChip Porcine genome array was used to profile the gene expression in porcine mesenteric lymph nodes over a time course of infection with S. Typhimurium, including the acute (8 hours post inoculation (hpi), 24 hpi, 48 hpi) and chronic (21 days post-inoculation (dpi)) stages of infection. Our objectives were to 1) identify and examine the stereotypical gene expression response within host MLN to S. Typhimurium infection, 2) characterize global host responses by revealing the specific features of the hosts innate immunity pathways, and 3) explore if and how S. Typhimurium may escape the host immune response and develop into a carrier state.

View SamplesTo understand the host transcriptional response to S. enterica serovar Choleraesuis (S. Choleraesuis), the first generation Affymetrix porcine GeneChip was used to identify differentially expressed genes in the mesenteric lymph nodes responding to infection at acute (8 hours (h), 24h, 48h post-inoculation (pi)) and chronic stages (21 days (d) pi)
Analysis of porcine transcriptional response to Salmonella enterica serovar Choleraesuis suggests novel targets of NFkappaB are activated in the mesenteric lymph node.

View SamplesNHEK cells were plated at a density of 8 x 10 000/cm2 and the cell cultures were grown for 24 hours before addition of 2 mM N-Acetyl-L-Cystein. RNA obtained from cultures grown for 1, 12 and 24 hrs after NAC treatment were compared to RNA from untreated cells at the corresponding time points. I.e 1 hour NAC treated vs 1 hour untreated cells etc. Each EXTRACT represents an individual mRNA extraction and subsequent cDNA synthesis from a batch of totalRNA originating from one cellculture dish.
