Description
Microglia 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.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
Inactivation of the yeast IME4 gene, the yeast homologue of METTL3, was shown to result in the loss of m6A in mRNA of mutant cells grown in sporulation medium. We attempted to characterize the effects of ime4 deletion on gene expression under vegetative and meiosis-inducing conditions. The results show that in vegetatively-growing ime4-/- cells there is an increased expression of the RME1 gene (repressor of meiosis) which prevents precocious entry into the meiotic program. Mutant yeast cells showed reduced expression levels of genes involved in ribosome biogenesis and gene expression processes. Surprisingly, despite the fact that a diploid strain was analyzed, there was also a striking change in the expression level of haploid-specific genes, suggesting that RNA methylation may be used to enforce the sexual identity of diploid cells, required for the implementation of the gametogenesis program. Consistently, when cells were induced to undergo meiosis, ime4-/- diploids failed to undergo the meiotic divisions. Among the genes showing reduced expression in the mutant were IME1 and IME2, the two known inducers of meiosis. Thus, the yeast IME4 gene plays an important role in the regulation of the developmental switch from vegetative cells into gametogenesis.

Description
We developed a novel approach, m6A-seq, for high-resolution mapping of the transcriptome-wide m6A landscape, based on antibody-mediated capture followed by massively parallel sequencing. Overall design: Identification of m6A modified sequences in HepG2 cells. HepG2 cells were incubated with either IFNg (200ng/ml) or HGF/SF (10 ng/ml) over night. Stress effects were tested in HepG2 cells by either 30 minutes incubation at 43ºC (heat shock) or UV irradiation of 0.04 J/cm2 followed by 4 hours of recovery in normal growing conditions prior to harvesting using Trypsin.

Description
To probe the tissue source (cancer cell VS stromal cell) of gene expression in the mixed tumor samples, we took advantage of a set of Urothelial Cancer patient-derived xenograft (PDX) models given that the transcriptome in these models is a mixture of human RNA (derived from cancer cells) and mouse RNA (derived from stromal cells). Overall design: The cohort includes 5 different patient-derived PDX models, 3 replicates for each model, and thus a total of 15 samples
