Microsatellite expansions often occur in non-coding regions of the genome. In this study, we test their effect on host transcript RNA processing. Overall design: RNA-seq on affected tissues and peripheral blood from control and affected patients.

View SamplesThe goal of this study was to isolate individual cochlear hair cells and supporting cells from wild type animals in order to characterize the transcriptome of functionally mature auditory hair cells in the mammalian cochlea. Overall design: Single-cell RNA sequencing is a powerful tool by which to characterize the transcriptional profile of low-abundance cell types, however its application to the inner ear has been hampered by the bony labyrinth, tissue sparsity and difficulties in dissociating the ultra-rare cells of the membranous cochlea. Herein, we present a method to isolate individual inner hair cells (IHCs), outer hair cells (OHCs) and Deiters' cells (DCs) from the murine cochlea at any post-natal time point. We isolated of 132 single cells from OHC, IHC, and DC cell types at postnatal day 15 (p15) and performed RNA-Sequencing of these cells using smartseq2 and Illumina HiSeq. An additional 12 single OHCs from the same timepoint were isolated and sequenced using smartseq2 and the Nanopore MinION 1D reads. We leverage single-cell RNA sequencing to analyze these three cell types and generate a multidimensional overview of their transcriptomes. The data provide new insights into OHC motility and the architecture of gene products implicated in hereditary hearing loss. This refined view of transcription in the organ of Corti will enhance to our understanding of the biology of hearing and deafness.

View SamplesMicroglia-like cells and neural cells were generated from several hES and hIPS lines. As subset was characterized by RNA seq and compared to expression profiles of published primary and induced samples. ABSTRACT: Microglia, the only lifelong resident immune cells of the central nervous system (CNS), are highly specialized macrophages which have been recognized to play a crucial role in neurodegenerative diseases such as Alzheimer's, Parkinson's and Adrenoleukodystrophy (ALD). However, in contrast to other cell types of the human CNS, bona fide microglia have not yet been derived from cultured human pluripotent stem cells. Here we establish a robust and efficient protocol for the rapid production of microglia-like cells from human embryonic stem (ES) and induced pluripotent stem (iPS) cells that uses defined serum-free culture conditions. These in vitro pluripotent stem cell-derived microglia-like cells (termed pMGLs) faithfully recapitulate the expected ontogeny and characteristics of their in vivo counterparts and resemble primary fetal human and mouse microglia. We generated these cells from multiple disease-specific cell lines, and find that pMGLs derived from MeCP2 mutant hES cells are smaller than their isogenic controls. We further describe a culture platform to study integration and live behavior of pMGLs in organotypic 3D-cultures. This modular differentiation system allows the study of microglia in highly defined conditions, as they mature in response to developmentally relevant cues, and provides a framework to study the long-term interaction of microglia residing in a tissue-like environment. Overall design: Individual donors/genetic backgrounds. Dataset inlcudes 4 differentiated neural progenitor biological replicates (NPC1-4), 2 primary fetal microglia samples as reference, 5 induced microglia samples grown in basal medium (pMGL1-5), 3 induced microglia samples grown in neural conditioned medium (pMGL1-3+NCM)

View SamplesMicroglia are the resident myeloid-lineage cells in the central nervous system. Despite myriad observations of microglia associated with various tissue pathologies in degenerative disease, their function in and contributions to the pathophysiological processes remain unclear. It is particularly uncertain whether microglia act harmfully to contribute to worsening of degeneration, act beneficially to combat disease-related dysfunction, or perform functions that result in both outcomes. In this dataset, we report RNA sequencing results from mice that undergo inducible ALS/FTLD-like degeneration and subsequent recovery. The goals were to identify whether microglia show transcriptional signatures commensurate with the disease stage or if they remain constant throughout. Additionally, we sought to understand whether there was a particular transcriptional or functional signature associated with functional recovery in the mice. The latter could lead to an understanding of how microglia may be targeted to combat disease and enhance recovery following or during degeneration. Overall design: mRNA profiles from microglia sorted from whole-spinal cord taken from doxycycline (DOX) inducible NEFH-tTa/tetO-208-hTDP43 (rNLS8, (+/+)) mice. In these mice, removal of doxycycline from the diet (DOX-OFF) induces transgenic expression and degeneration and reintroduction (DOX-ON) suppresses expression and enables recovery. We report profiles from rNLS8 mice that were DOX-OFF for 2 weeks (N=8) or 6 weeks (N=7), or DOX-OFF for 6 weeks followed by DOX-ON for 1 week (N=9). We also report profiles from control samples that include: rNLS8 mice that were DOX-ON for 6 weeks (N = 6) as asymptomatic genetic controls and WT (-/-) littermates that were DOX-OFF for 2 weeks (N=4), 6 weeks (N=1), or DOX-OFF for 6 weeks followed by 1 week DOX-ON (N=3) as asymptomatic doxycycline controls.
