Description
The process for making monocyte derived DCs (moDCs) has been previously described (46). All analysis was performed on day 5 immature DCs. Etanercept 10mg/mL was added to experimental wells on days 0, 2, and 4. We chose this concentration of etanercept as it approximates the plasma concentration of drug when given 50mg BIW.

Renal recovery following injury relies on cellular regeneration. In the mouse kidney following injury, injured epithelial cells undergoes de-differentiate, proliferate and re-differentiate into functional cells, following a a tightly controlled genetic programme where specific sets of genes are up-regulated.

Description
To understand the extent of Smad-mediated gene regulation in the colon, we isolated colon epithelium from Smad4?Lrig1 and from Smad4+ control mice (either mice lacking a CreERT allele and treated with tamoxifen, or mice bearing a CreERT allele but treated with vehicle only) and analyzed the colonic epithelium by RNAseq. The ability of TGFß1 and/or BMP2 to block TNF-mediated induction of Ccl20 from our study suggests that these Smad-mediated pathways may act as gatekeepers for induction of other inflammation-associated genes. To determine if Smad-mediated signaling blocks all or specific subsets of TNF-induced genes, we analyzed both colonocytes and mouse colonoid treated with or without TNF, TGFß1, and BMP2 by RNA seq. Overall design: In total, three RNAseq experiments were performed and three biological replicates were used for each condition: 1. Colon epithelium from Smad4?Lrig1 and from Smad4+ control mice was isolated. Total RNA was isolated from these tissues using RNeasy kit (Qiagen). Processing of RNA using a TruSeq Stranded mRNA sample prep kit was conducted according to the manufacturer's instructions (Illumina, San Diego, CA). 32~37 million 51 base pair single-end reads were generated per sample. 2. Total RNA was isolated from colonocytes treated with or without TNF, TGFß1, and BMP2 using RNeasy kit (Qiagen). Processing of RNA using a TruSeq Stranded mRNA sample prep kit was conducted according to the manufacturer's instructions (Illumina, San Diego, CA). 26~50 million 75 base pair paired-end reads were generated per sample. 3. Total RNA was isolated from mouse colonoid treated with or without TNF, TGFß1, and BMP2 using RNeasy kit (Qiagen). Processing of RNA using a TruSeq Stranded mRNA sample prep kit was conducted according to the manufacturer's instructions (Illumina, San Diego, CA). 50~72 million 75 base pair paired-end reads were generated per sample.

Description
PTBP1 and PTBP2 control alternative splicing programs during neuronal development, but the cellular functions of most PTBP1/2-regulated isoforms remain unknown. We show that PTBP1 guides developmental gene expression by regulating the transcription factor Pbx1. We identify exons that are differentially spliced when mouse embryonic stem cells (ESCs) differentiate into neuronal progenitor cells (NPCs) and neurons, and transition from PTBP1 to PTBP2 expression. We define those exons controlled by PTBP1 in ESCs and NPCs by RNA-seq analysis after PTBP1 depletion and PTBP1 crosslinking-immunoprecipitation. We find that PTBP1 represses Pbx1 exon 7 and the expression of its neuronal isoform Pbx1a in ESC. Using CRISPR-Cas9 to delete regulatory elements for exon 7, we induce Pbx1a expression in ESCs, finding that this activates transcription of specific neuronal genes including known Pbx1 targets. Thus PTBP1 controls the activity of Pbx1 and suppresses its neuronal transcriptional program prior to differentiation. Overall design: 46C mESCs were differentiated in mNPCs. The mNPCs were treated with 10 nM control, Ptbp1, Ptbp2, or Ptbp1 and Ptbp2 siRNAs for 48 hours. The knockdowns were performed using 2 independent sets of siRNAs. Poly-A RNA was isolated for RNA-sequencing and splicing analyses.

Description
Cbx3 (HP1?) that is a member of the heterochromatin protein 1 family play important roles in development and differentiation. To determine the regulatroy mechanisms of Cbx3 during neural differentiation from ESCs to NPCs, we performed RNA-seq analysis of ESCs or ESC-derived NPCs depleted for Cbx3 or Cbx3-assocatied Mediator subunit Med26. Overall design: ESCs or ESC-derived NPCs were transfected with control siRNA targeting to luciferase or siRNA mediated knockdown of Cbx3 or Med26. RNAs were extracted from control or knockdown group and subjected to library preparation and deep sequencing.

Cbx3 maintains lineage specificity during neural differentiation.

Description
-cell identity is determined by tightly regulated transcriptional networks that are modulated by extracellular cues, thereby ensuring -cell adaptation to the organisms insulin demands. We have observed in pancreatic islets that stimulatory glucose concentrations induced a gene profile that was similar to that of freshly isolated islets, indicating that glucose-elicited cues are involved in maintaining -cell identity. Low glucose induces the expression of ubiquitous genes involved in stress responses, nutrient sensing, and organelle biogenesis. By contrast, stimulatory glucose concentrations activate genes with a more restricted expression pattern (- and neuronal- cell identity). Consistently, glucose-induced genes are globally reduced in islets deficient with Hnf1a (MODY3), characterized by a deficient glucose metabolism. Of interest, a cell cycle gene module was the most enriched among the variable genes between intermediate and stimulatory glucose concentrations. Glucose regulation of the islet transcriptome was unexpectedly broadly maintained in islets from aged mice. However, the cell cycle gene module is selectively lost in old islets and the glucose activation of this module is not recovered even in the absence of the cell cycle inhibitor p16.
