Description
A comparative bulk cell RNA-seq analysis of diverse intestinal stem cell populations was performed, for cells expressing the following markers: Lgr5-eGFPhi, Cd166+, Cd24lo, Grp78, upper side population (SP), Bmi1, mTert, Hopx, Dclk1, a lower side population (SP) Overall design: For each ISC population of interest, three independent mice (biological replicates) were used. From each mouse, a marker-“positive” and a marker-“negative” population were collected, as well as a "total" population.

Affymetrix Human Genome U133A Array (hgu133a)
Description
Summary: Genetic disorders of muscle cause muscular dystrophy, and are some of the most common inborn errors of metabolism. Muscle also rapidly remodels in response to training and innervation. Muscle weakness and wasting is important in such conditions as aging, critical care medicine, space flight, and diabetes. Finally, muscle can also be used to investigate systemic defects, and the compensatory mechansisms invoked by cells to overcome biochemical and genetic abnormalities. Here, we provide a 13 group data set for comparative profiling of human skeletal muscle. Groups studied are: Normal human skeletal muscle, Acute quadriplegic myopathy (AQM; critical care myopathy), Juvenile dermatomyositis (JDM), Amyotophic lateral sclerosis (ALS), spastic paraplegia (SPG4; spastin), Fascioscapulohumeral muscular dystrophy (FSHD), Emery Dreifuss muscular dystrophy (both X linked recessive emerin form; autosomal dominant Lamin A/C form), Becker muscular dystrophy (partial loss of dystrophin), Duchenne muscular dystrophy (complete loss of dystrophin), Calpain 3 (LGMD2A), dysferlin (LGMD2B), FKRP (glycosylation defect; homozygous for a missense mutation). U133A and U133B microarrays are both available.

Description
Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most frequent cause of familial and sporadic Parkinsons disease (PD). Here, we investigated in parallel gene and microRNA transcriptome profiles of three different LRRK2 mouse models. Striatal tissue was isolated from adult LRRK2 knockout mice, as well as mice expressinghuman LRRK2 wildtype (hLRRK2-WT) or PD-associated R1441G mutation (hLRRK2-R1441G).

Description
We use mice containing a gene trap in the first intron of the Rest gene, which effectively eliminates transcription from all coding exons, to prematurely remove REST from neural progenitors. We find catastrophic DNA damage that occurs during S-phase of the cell cycle and concominant with activation of p53 pro-apoptotic sgnalling, with consequences including abnormal chromosome separation, apoptosis, and smaller brains.

Description
We use mice containing a gene trap in the first intron of the Rest gene, which effectively eliminates transcription from all coding exons, to prematurely remove REST from neural progenitors. We find catastrophic DNA damage that occurs during S-phase of the cell cycle, with consequences including abnormal chromosome separation, apoptosis, and smaller brains. Further support for persistent effects is the latent appearance of proneural glioblastomas in adult mice also lacking the tumor suppressor, p53. A Rest deficient mouse line generated previously, using a conventional gene targeting approach, does not exhibit these phenotypes, likely due to a remaining C terminal peptide that still binds chromatin and recruits REST chromatin modifiers.Our results indicate that REST-mediated chromatin remodeling is required for proper S-phase dynamics, prior to its well-established role in relieving repression of neuronal genes at terminal differentiation.

Description
Ocular immune privilege (IP) limits immune surveillance of intraocular tumors as certain immunogenic tumor cell lines (P815, E.G7-OVA) that are rejected when transplanted in the skin grow progressively when placed in the anterior chamber (a.c.) of the eye. As splenectomy (SPLNX) is known to terminate ocular IP, we characterized immune mechanisms responsible for spontaneous rejection of intraocular tumors in SPLNX mice as a first step toward identifying how to restore tumoricidal activity within the eye. Microarray data showed a 3-fold increase in interferon (IFN)- and a 2.7-fold increase in Fas ligand (FasL). There was a robust increase in transcripts (127 of 408 surveyed) from interferon (IFN)-stimulated genes and a marked decrease (in 40 of 192 surveyed) in the expression of cell-cycle-associated genes. Non-microarray data confirmed that IFN, FasL and CD8+ T cells but not perforin or TNF were required for elimination of intraocular E.G7-OVA tumors that culminated in destruction of the eye (ocular phthsis). IFN and FasL did not target tumor cells directly as the majority of SPLNX IFNR1-/- mice and Fas-defective lpr mice failed to eliminate ocular E.G7-OVA tumors that expressed Fas and IFNR1. Bone marrow chimeras showed that immune cell expression of IFNR1 and Fas was critical and that SPLNX increased the frequency of activated macrophages within ocular tumors in an IFN- and Fas/FasL-dependent manner. Rejection of intraocular tumors was associated with increased ocular mRNA expression of several inflammatory genes including FasL, NOS2, CXCL2 and T-bet. Our data support a model in which IFN- and Fas/FasL-dependent activation of intratumoral macrophage by CD8+ T cells promotes severe intraocular inflammation that indirectly eliminates intraocular tumors by inducing phthisis. The immunosuppressive mechanisms which maintain ocular IP likely interfere with the interaction between CD8+ T cells and macrophage to limit immunosurveillance of intraocular tumors.

Description
p63 mutations have been associated with several human hereditary disorders characterized by ectodermal dysplasia such as EEC syndrome, ADULT syndrome and AEC syndrome . The location and functional effects of the mutations that underlie these syndromes reveal a striking genotype-phenotype correlation. Unlike EEC and ADULT that result from missense mutations in the DNA-binding domain of p63, AEC is solely caused by missense mutations in the SAM domain of p63. We report a study on the TAp63a isoform, the first to be expressed during development of the embryonic epithelia, and on its naturally occurring Q540L mutant derived from an AEC patient. To assess the effects of the Q540L mutation, we generated stable cell lines expressing TAp63a wt, DeltaNp63 alpha or the TAp63 alpha-Q540L mutant protein and used them to systematically compare the cell growth regulatory activity of the mutant and wt p63 proteins and to generate, by microarray analysis, a comprehensive profile of differential gene expression. We found that the Q540L substitution impairs the transcriptional activity of TAp63a and causes misregulation of genes involved in the control of cell growth and epidermal differentiation.
