Project description:To identify the consequences of mechanical stress of differentiated cardiac muscles from healthy- and PPCM individuals. RNA-sequencing data was obtained from 4 individuals from 2 families. Each family had one member with PPCM and one healthy. Individual 1 and 2 were sisters, one healthy, one with PPCM. Individual 3 and 4 were a healthy mother and PPCM daughter. From each patient 4, 6, 1 and 3 clones were derived, respectively. From each clone multiple pairs of cells were collected and either stretched or left static to a total of 40 pairs, with 2 unpaired static samples.

Project description:A simple method is presented to reset human pluripotent cells to a naive state via transient histone deacetylase inhibition and maintenance in chemically-defined naive stem cell culture media. Cells can be reset without transgenes and expanded continuously either on feeders or alternative substrates in feeder-free conditions. Multiple cell lines of varying origin were reset and characterised in parallel with conventionally cultured counterparts.

Project description:Sphere-forming progenitor cells can be isolated from the fetal and adult mammalian inner ear and give rise to inner ear specific cell types in vitro. Here, we provide phenotypical and functional characterization of a new pool of auditory progenitors as sustainable source for sphere-derived auditory neurons. The so-called phoenix auditory neuroprogenitors, isolated from the A/J mouse spiral ganglion, exhibit nearly unlimited intrinsic self-renewal properties (beyond 40 passages). At any passage, phoenix spheres can be efficiently differentiated by withdrawing growth factors into mature spiral ganglion cells, expressing both neurons and glial cells phenotypic markers and exhibiting similar functional properties as mouse spiral ganglion explants and human sphere-derived spiral ganglion cells. The present dataset includes RNAseq-based transcriptome analysis of phoenix auditory neurons following 7 days of differentiation. mRNA levels in differentiated cells are expressed relatively to neuroprogenitor spheres of equivalent passage (paired samples at passage 12, 21 and 36)

Project description:Sepsis is an exaggerated immune response upon infection with lipopolysaccharide (LPS) as the main causative agent. LPS-induced activation and apoptosis of endothelial cells (EC) can lead to organ dysfunction and finally organ failure. We have previously demonstrated that the first twenty amino acids of the Apurinic/Apyrimidinic Endodeoxyribonuclease 1 (APEX1) are sufficient to inhibit EC apoptosis. To identify genes whose regulation by LPS is affected by this N-terminal APEX1 peptide, EC were transduced with an expression vector for the APEX1 peptide or an empty control vector and treated with LPS. Following RNA deep sequencing, genes upregulated in LPS-treated EC expressing the APEX1 peptide were identified bioinformatically.

Project description:The host response of the primary intestinal epithelium to human astrovirus (HAstV infection has not been elucidated to date. In order to characterize the global effects of AstV infection on human intestinal tissue, we performed transcriptional profiling of VA1-infected human intestinal enteroids (HIE) by RNAseq. We used the D124 line for our studies since AstV infections are typically symptomatic in very young children, and our prior infection studies indicated rapid infection in D124. D124 HIE were mock-infected or infected with VA1 (MOI = 1) and harvested at 0 hpi (i.e., 1h post-adsorption), 12 hpi, and 24 hpi (Fig 4A). To monitor viral replication, VA1 genome copies were detected by RT-qPCR, revealing an approximately 1 and 2 log increase at 12 and 24 hpi, respectively (Fig 4B). Cellular RNA was extracted and analyzed by RNAseq. Genome copies as determined by RT-qPCR were correlated to the proportion of viral transcripts in the pool of sequenced RNA collected from the same HIE cultures, revealing an exceptionally strong correlation between the two measures of viral replication (r2 = 0.98, P = 2.5 x 10^-14. VA1 genome reads contributed 0.05 ± 0.02 x% of total RNAseq reads at 24 hpi, further confirming robust infection. Differential expression analysis was performed to identify genes associated with the HIE host response to VA1 infection. A total of 23,220 genes were detected. Differential expression of genes at each timepoint was graphed in a volcano plot. The log2 fold change in normalized expression (transcripts per million reads [TPM]) of all expressed host genes in VA1-infected HIEs relative to mock-infected HIE is shown on the x-axis. The -log10 transformed P-value is given on the y-axis. Genes that are significantly up-regulated (adjusted P < 0.05) in VA1-infected D124 HIE relative to mock-infected HIE are colored red, while significantly down-regulated genes are colored blue. Overall, after a 1 hour adsorption (0 hpi), 110 genes were significantly upregulated and 136 genes were downregulated , indicating changes due to viral attachment to cells. This number was reduced at 12 hpi, with 8 significantly upregulated and 5 downregulated genes. At 24 hpi, 154 upregulated and 49 downregulated genes compared to the mock-infected control were identified. We next identified the top 15 significantly up- and down-regulated genes at 24 hpi. This group of genes was used to generated a heatmap of the mean scaled fold-change (Z-score) in expression of each of them in virus-infected HIE relative to mock-infected HIE at each timepoint (Fig 4D). Most of the upregulated genes at 24 hpi were involved in type I and type III interferon (IFN) signaling. Of the IFN genes, IFNL1 was highly upregulated, with IFNA1 and IFNB1 upregulation being slightly lower (Fig S4B). No upregulation was observed for the genes encoding IFN-γ, or the type I and III IFN receptors (data not shown). The top 12 IFN-stimulated genes (ISGs) also positively correlated with VA1 infection (Fig S4C). Conversely, the top 12 downregulated genes, including fermitin family member 1 (FERMT1), signal peptide peptidase like 3 (SPPL3), and tetratricopeptide repeat domain 19 (TTC19) negatively correlated with VA1 infection (Fig S4D). Next, we evaluated lists of the top 100 up- and down-regulated genes at 24 hpi using an over-abundance test to identify significantly over-represented REACTOME pathways in these lists. These data revealed that the top four significantly enriched pathways among upregulated genes were all related to innate antiviral signaling (Fig 4E), which will be investigated in more detail below. For downregulated genes, the top two pathways were “neurexins and neuroligins”, which play signaling roles in synapse development, and “protein-protein interactions at synapses”. The biological significance of synapses during astrovirus infection remains to be elucidated. In order to evaluate the potential for coordinated and directional activation of genes in known signaling pathways, we applied gene set enrichment analysis (GSEA) to our RNAseq differential expression data. Based on the strong dominance of IFN signaling pathways, we focused our GSEA analysis on immune signaling (Fig 4F). During the adsorption phase, nucleic acid pattern recognition receptor signaling pathways (TLRs, STING) were upregulated, consistent with their early role in virus recognition and induction of IFN signaling. At 24 hpi, these early signaling events had been largely replaced by the later phase of IFN signaling and expression of ISGs. Taken together, these data indicate that VA1 infection predominantly elicited antiviral IFN signaling in HIE-derived fetal duodenum at the transcript level.

Project description:We used primary human CHH (cartilage-hair hypoplasia) and control fibroblasts in a chondrogenic transdifferentiation model (FDC; fibroblast-derived chondrocytes) to determine the chondrogenic capacity and differential pathway regulation of CHH cells. For the sequencing experiment, dermal fibroblasts from control donors (n=4) and CHH patients (n=4) were isolated from skin biopsies, plated at high density into wells coated with aggrecan, and cultured for three days in an FDC transdifferentiation medium. Total RNA was isolated at three different time points (Day 0, 1, and 3; in total 24 RNA samples), and sequenced using the NextSeq platform (Illumina).

Project description:Single-cell RNA-seq was performed on homozygous Sox2 knockout induced pluripotent stem (iPS) cells, where residual Sox2 expression is observed from incompletely silenced retroviral transgenes. These were compared to Sox2-low iPS cells rescued by exogenous Sox2 transgenic expression, and wild-type iPS cells to assess the lineage expression profile of Sox2-low cells and degree of transcriptional heterogeneity in each population.
