View SamplesInduced pluripotent stem (iPS) cells have been derived from various somatic cell populations through ectopic expression of defined factors. It remains unclear whether iPS cells generated from different cell types are molecularly and functionally similar. Here, we show that iPS cells obtained from fibroblasts, hematopoietic and myogenic cells exhibit distinct transcriptional and epigenetic patterns. Moreover, we demonstrate that cellular origin influences the in vitro differentiation potentials of iPS cells into embryoid bodies and different hematopoietic cells. Our results suggest that low-passage iPS cells retain a transient epigenetic memory of their somatic cells of origin, which manifests as differential gene expression and altered differentiation capacity. These observations might affect ongoing attempts to use iPS cells for disease modeling and also could be exploited for potential therapeutic applications to enhance differentiation into desired cell lineages.

View SamplesRNA sequencing libraries were made for A-498 and 786-O to detect the transcripts regulated by the lincRNA comparing knockdown and the non-targeting control. Overall design: Two siRNAs were designed, non-target control and the siRNAs were introduced to the cell lines A-498 and 786-O separately by Lipofectamine 2000. After 16 hours total RNA were extracted. Barcoded cDNA libraries were then prepared from total RNA using the Illumina TruSeq RNAseq kit, and sequenced (single-end 36-bp reads) on an Illumina HiSeq instrument.

View SamplesThe experiment aimed at determing the influence of mast cell deficiency on the transcriptome of skin-infiltrating leukocytes in K14HPV16 mice at 2month and 6month of age. Overall design: Skin-inflitrating leucocytes were FACS-purified from mast cell proficient (Mcpt5-Cre-) and mast cell deficient (Mcpt5-Cre+) K14HPV16 mice. Mast cells (CD117 high, FCeR1 high) were excluded from the sorting gate. In order to control for minimal mast cell contamination during sorting from K14HPV16 Mcpt5-Cre- skin, mast cell signature transcripts were identified by comparing transcriptomes of samples fromK14HPV16 Mcpt5-Cre- mice in which mast cells were flow cytometrically included vs excluded.
Although Abundant in Tumor Tissue, Mast Cells Have No Effect on Immunological Micro-milieu or Growth of HPV-Induced or Transplanted Tumors.

View SamplesRNA seq was used to compare the expression profile of macrophages in presence and absense of mast cells. MB49 cells were injected i.d. into Mcpt5-Cre+ R26DTA animals and cre-negative littermates. Macrophages were sorted at 20 d.p.i. Overall design: Macrophage RNA profiles of MB49 TAMs (tumor-associated macrophages), harvested at 20 d.p.i. in MC-Proficient and MC-deficient animals

View SamplesWe developed a 5''RNA-seq methodology to concurrently assess gene expression and start-site usage changes. We applied this methodology to study hypertrophic cardiomyopathy in mice harboring a human deleterious mutation. Overall design: 5''RNA-seq analysis of transcriptomes from mouse hearts with or without hypertrophic cardiomyopathy. Biological replicates were pooled into a single sequencing run. 5''RNA-seq methodology consists of enhanced sequencing of 5'' ends and computational assessment of changes at start-sites of genes.
5'RNA-Seq identifies Fhl1 as a genetic modifier in cardiomyopathy.

View SamplesWe report that phosphorylated ribosomes can be immunoprecipitated from mouse brain homogenates, resulting in enrichment of transcripts expressed in activated neurons. Overall design: Mice were either injected with a concentrated salt solution or vehicle, hypothalami dissected, and phosphorylated ribosomes immunoprecipitated. RNA was sequenced from the input and IP for each condition (4 samples total).

View Samplescomparison of expression of wildtype lungs and lungs with hypomorphic expression of nmyc. the lungs were pooled from several biological samples. The hypomorphoic mutant was orignally published in Moens CB et al [PMID: 1577267]. this is part of a larger collection of data comparing nmyc misexpression in the lung (gain of fucntion) and protein expression in the hypomorphic lungs.
