Description
We transduced clonally MLL-AF9 leukemia cells expressing cas9 with sgRNA targeting the jumonji and zinc finger domains of JMJD1C. GFP (MLL-AF9) and TdTomato (sgRNA) double positive cells were sorted on Day 6 after transduction. Total RNA was isolated followed by mRNA selection. cDNA libraries were generated and NextGen Sequencing was performed. Overall design: We performed RNA-seq in mouse MLL-AF9 cas9 cells harboring sgRNA against jumonji and zinc finger domains of JMJD1C or renilla.

Description
A new Treg-specific, FoxP3-GFP-hCre BAC transgenic was crossed to a conditional Dicer knock-out mouse strain to analyze the role of microRNAs (miRNA) in the development and function of regulatory T cells (Tregs). Although thymic Tregs developed normally in this setting, the cells showed evidence of altered differentiation and dysfunction in the periphery. Dicer-deficient Treg lineage cells failed to remain stable as a subset of cells down-regulated the Treg-specific transcription factor, FoxP3, while the majority expressed altered levels of multiple genes and proteins (including Neuropilin 1, GITR and CTLA-4) associated with the Treg fingerprint. In fact, a significant percentage of the Treg lineage cells took on a Th memory phenotype including increased levels of CD127, IL-4, and interferon-g. Importantly, Dicer-deficient Tregs lost suppression activity in vivo; the mice rapidly developed fatal systemic autoimmune disease resembling the FoxP3 knockout phenotype. These results support a central role for miRNAs in maintaining the stability of differentiated Treg function in vivo and homeostasis of the adaptive immune system.

Description
Regulatory T cells (Tregs) are essential for maintaining proper immune homeostasis. Extracellular signals (e.g. TCR, CD28, IL-2R) are necessary for the generation and maintenance of Tregs, but how these signals are integrated to control the gene expression patterns of Tregs is less clear. Here we show that the epigenetic regulator, Ezh2, was induced by CD28 costimulation and Ezh2 activity was elevated in Tregs as compared to conventional CD4+ T cells. Deletion of Ezh2 in mouse Tregs led to a progressive autoimmune disease because Tregs were compromised after activation, losing proper control of essential Treg lineage genes and adopting a gene expression pattern similar to Foxp3-deficient ‘Tregs.’ Lineage-tracing of Ezh2-deficient Tregs in vivo confirmed that the cells were destabilized selectively in activated Treg populations, which led to a significant loss of Tregs in non-lymphoid tissues. These studies reveal an essential role for Ezh2 in the maintenance of Treg “identity” during cellular activation and differentiation. Overall design: RNAseq of sorted populations of CD62Lhi or CD62Llo Tregs for both Ezh2-HET (Foxp3YFP-Cre/Foxp3WT;Ezh2fl/+ female mice) and Ezh2-KO (Foxp3YFP-Cre/Foxp3WT;Ezh2fl/fl female mice) were generated, in triplicate for each condition, using Illumina HiSeq 2500 single-end 50bp sequencing platform.

Description
Androgen receptor (AR) signaling is a distinctive feature of prostate cancer (PC) and represents the major therapeutic target for the treatment of metastatic disease. Though highly effective, AR antagonism has the potential to generate tumors that bypass a functional requirement for AR activity. We show here that a phenotypic shift has occurred in metastatic PCs with the emer-gence of a double-negative AR-null neuroendocrine-null phenotype that is notable for MAPK and FGF pathway activity. To identify mechanisms capable of sustaining PC survival, we gener-ated a model system designated AR program-independent prostate cancer (APIPC) which re-sists AR-targeted therapeutics, lacks neuroendocrine features, expresses high levels of FGF8 and the ID1 oncogene, and activates MAPK signaling. Pharmacological blockade of MAPK or FGF signaling inhibited APIPC tumor growth, supporting FGF/MAPK as a therapeutic avenue for treating AR-null PC. Overall design: RNA sequencing of human prostate tumor cell lines using the Illumina TruSeq Library prep and sequenced on Illumina HiSeq 2500.
