View SamplesMolecular mechanisms that are responsible for the development of human skin epithelial cells are not completely understood so far. As a consequence, the efficiency to establish a pure skin epithelial cell population from human induced pluripotent stem cells (hiPSC) remains poor. Using an approach including RNA interference and high-throughput imaging of early epithelial cells, we could identify candidate kinases which are involved in skin epithelial differentiation. Among them, we found HIPK4 to be an important inhibitor of this process. Indeed, its silencing increased the amount of generated skin epithelial precursors, increased the amount of generated keratinocytes and improved growth and differentiation of organotypic cultures, allowing for the formation of a denser basal layer and stratification with the expression of several keratins. Our data bring substantial input in the regulation of human skin epithelial differentiation and for improving differentiation protocols from pluripotent stem cells.

View SamplesAnalysis of gene expression over serial 150um sections of a single gestational week 18 human neocortical specimen. The hypothesis tested with this dataset was that a transcriptional signature of GABAergic neurons could be isolated via unsupervised gene coexpression analysis due to variation in the abundance of this cell type from section to section. This dataset is the second of its kind generated using this method (Gene Coexpression Analysis of Serial Sections, or GCASS).

View SamplesMSL (Male-specific lethal) complex increases transcription on the single X chromosome of Drosophila males in order to equalize expression of X-linked genes between males (XY) and females (XX). The increase in transcript levels correlates with MSL- dependent acetylation of histone H4 at K16 within the bodies of active genes, but identification of the transcriptional step affected has not been possible. In this study, we use global run-on sequencing (GRO-seq) to examine the specific effect of MSL complex on RNA Polymerase II (RNAP II) on a genome-wide level. Results indicate that MSL complex enhances transcription by facilitating the progression of RNAP II across the bodies of active X-linked genes. Improving transcriptional output downstream of typical gene-specific control may explain how dosage compensation can be imposed on the diverse set of genes along an entire chromosome. Overall design: Global Run-On Sequencing (GRO-Seq) reads, i.e., RNA-Seq of nascent RNA transcripts, from D. Melanogaster SL2 cells. Two biological replicates were analyzed.

View SamplesAnalysis of the cystic fibrosis gene Cftr in the colon and small intestine of Cftr-deficient murine model. The hypothesis was loss of Cftr altered expression of genes important in intestinal homeostasis and oncogenic signaling pathways. The results identified potential roles of Cftr in up- or down-regulating major gene clusters that belong to groups of immune response, ion channel, intestinal stem cell and other growth regulators. Overall design: The experiments were designed to analyze the role of Cftr-deficiency in tumorigenesis. The goal of this study was to identify genes and pathways associated with Cftr-deficiency in Apc wildtype and ApcMin mice. Total RNAs were isolated from mice, and subjected to deep sequencing, in duplicates, using Illumina HiSeq 2500. Samples that were sequenced in the same batch were analyzed in pair-wise using Tophat-Cuffdiff pipeline as outlined in Nature Protocol from Trapnell C. et al, 2012. The results indicated that Cftr-deficiency overlapped with genes and pathways involved in immune and inflammatory signaling, stem cell regulation, and Wnt/beta catenin signaling. Total RNA was isolated from multiple colon tumors and multiple small intestine tumors from Apc wildtype Cftr-deficient mice, ApcMin Cftr-deficient mice, and ApcMin Cftr wildtype mice. Total RNA was also obtained from Apc wildtype normal colon (epithelial cells) and normal duodenum (whole duodenum minus villi) from three Cftr wildtype and three Cftr-deficient mice. RNA Seq was then conducted on all samples with at least two replicates for each biological sample. Please note that 1) The 23 mice were processed in several batches, and two sequencing runs were carried out at two different dates. Â To control for the batch effect of sequencing, some samples were included in both runs (run1 and run2). 2) To reach the desired sequencing depth and to keep loading balance, each sample was split into halves, and sequenced on two lanes (L007 and L008 for run1, L006 and L007 for run2). therefore, for 11 samples, there are 4 technical replicates, including the 2-batches and 2-lane sequencing method. For the remaining 12 samples, there are 2 technical replicates, referring to the 2-lane sequencing. 3) some of the mice are heterozygous mutant of CFTR gene (CFTRhet), named as "CFTR knockdown".
