Expression profiling of miR-142 deficient Treg cells

Project description:miR-142 gene is specifically and abundantly expressed in hematopoietic lineages. Mice with specific deletion of this miRNA gene in Treg develop fatal autoimmunity. We used RNA-seq to detect whole transcriptome changes in miR-142 null Treg cells.

Gene expression profiling of thymically-derived regulatory T cells from miR-142-deficient versus wild-type mice

Project description:Regulatory T cells (Tregs) play a fundamental role in immune tolerance via control of self-reactive effector T cells (Teffs). The development and function of the Treg lineage is critically dependent on the transcription factor Forkhead box P3 (Foxp3). Mice with a Treg-specific deletion of miRNAs, also develop a spontaneous, lethal autoimmune disease virtually indistinguishable from that seen in Foxp3-decicient mice demonstrating that miRNAs are critical for establishment of Treg-mediated peripheral tolerance. However, the set of miRNAs responsible for this functional deficiency has yet to be fully defined. Using Foxp3 ChIP-seq data we identified Mir142 as the only miRNA gene associated with a super-enhancer bound by FOXP3 suggesting that miR-142 is important for Treg function. To identify genes directly regulated by miR-142 in Tregs we profiled the changes in gene expression upon conditional deletion of miR-142 in thymically-derived Treg cells.

Gene profiling changes in BM Lin-Sca-1+c-Kit+ cells (LSKs) from miR-142-/- (KO), miR-142+/+ (WT), miR-142-/- BCR-ABL (BC CML) and miR-142+/+ BCR-ABL (CP CML) mice. [bulk RNA-Seq]

Project description:To gain insight into how miR-142 deficit drives a BC-like transformation, we performed RNA-seq on bone marrow (BM) Lin-Sca-1+c-Kit+ cells (LSKs) harvested from normal miR-142+/+ (wt) and miR-142−/− (miR-142 KO) mice, as well as from leukemic miR-142+/+ BCR-ABL (CP CML) and miR-142−/− BCR-ABL (BC CML) mice, two weeks after BCR-ABL induction. We then performed gene expression profiling analysis using data obtained from RNA-seq of 24 samples of LSK cells from 4 mouse strains (KO vs WT, KO CML vs CML).

Epression profiling of miR-142 deficient CD19+ B cells

Project description:miR-142 gene is specifically and abundantly expressed in hematopoietic cells. Mice that lack this miRNA gene develop immunodeficiency and display altered hematopoeisis. We used microarrays to detect whole transcriptome changes in miR-142 null B cells. RNA from purified WT(n=3) and miR-142 KO (n=3) CD19+ B cells was extracted and hybridized to Affymetrix GeneChips. Samples in WT and KO groups are biological replicates and were isolated in age and gender matched mice.

Expression data on Treg cells isolated from wildtype mice and miR-125a deficient mice

Project description:We found miR-125a was a key regulator that stabilizes the commitment and immunoregulatory capacity of Treg cells.To gain insights into the general functional features of miR-125a-deficient Treg cells, we performed a genome-wide gene array analysis on Treg population isolated from the spleens of 6 to 8-week-old miR-125a-deficient and WT mice We sorted CD4+CD25hi Treg population from the spleens of 6 to 8-week-old miR-125a-deficient and their littermate WT mice. Cells were collected and total RNA was extracted for Affymetrix GeneChip®Mouse Genome 430 2.0 Array

small RNA-Seq of miR-181 deficient Treg cells

Project description:The interdependence of selective cues during development of regulatory T (Treg) cells in the thymus and their suppressive function remains incompletely understood. Here we analyzed this interdependence by taking advantage of highly dynamic changes of miR-181a/b-1 during late T-cell development with very high levels of expression during thymocyte selection followed by massive downregulation in the periphery. Loss of miR-181a/b-1 resulted in inefficient de novo generation of Treg cells in the thymus, but simultaneiously permitted homeostatic expansion in the periphery in the absence of competition. Modulation of T-cell receptor (TCR) signal strength in vivo indicated that miR-181a/b-1 controlled Treg cell formation via establishing adequate signaling thresholds. Unexpectedly, miR-181a/b-1-deficient Treg cells displayed elevated suppressive capacity in vivo, in line with elevated levels of CTLA-4 protein, but not mRNA, in thymic and peripheral Treg cells. Therefore, we propose that intrathymic miR-181a/b-1 controls development of Treg cells and imposes a developmental legacy on their peripheral function.

Expression data from stable clones of BE(2)M17 cell line expressing miR-142 or miR-null

Project description:MiR-142 is upregulated in neurons in HIV and SIV encephalitis. We have created stable clones of the BE(2)M17 human neuroblastoma cell line overexpressing miR-142. Gene expression in these miR-142-expressing clones was compared to stable clones transfected with control miR-null in order to identify miR-142 targets relevant to neuronal dysfunction in HIV encephalitis.
