Description
Alternative splicing of pre-mRNA is a prominent mechanism to generate protein diversity, yet its regulation is poorly understood. Here, we demonstrate a direct role for histone modifications in alternative splicing. We find distinctive histone modification signatures which correlate with splicing outcome in a set of human genes. Modulation of histone modifications causes splice site switching. The mechanism for histone-mediated splice site selection involves a histone mark which is read by a chromatin protein, which in turn recruits a splicing regulator. These results outline an adaptor system for reading of histone marks by the pre-mRNA splicing machinery. Overall design: To obtain an estimate of how many PTB-dependent alternative splicing events are regulated by SET2/MRG15-mediated recruitment of PTB, we carried out a genomewide comparative analysis of alternative splicing in hMSC cells depleted of either SETD2, MRG15 or PTB using specific siRNAs, or mock-depleted using a control siRNA.

Description
Prenatal exposure to valproic acid, an established anti-epileptic drug, has been reported to impair postnatal cognitive function of children from epileptic mothers. Nevertheless, its pathology and proper treatment to minimize the effects remain unknown. In mice, we found that the postnatal cognitive function impairment was mainly caused by a reduction of adult neurogenesis and abnormal neuronal features in the hippocampus, which could be ameliorated by voluntary running.

High dietary fat intake is a major risk factor for the development of obesity, which is frequently associated with diabetes. To identify genes involved in diabetic nephropathy, GeneChip Expression Analysis was employed to survey the glomerular gene expression profile in diabetic KK/Ta mice fed with a high-fat diet (HFD).

Description
The goals of this study are to comprehensively identify genes controlled by Jmjd6 in the thymic stroma, and to identify a novel alternative splicing mechanism. Methods: Samples were WT and Jmjd6-/- fetal thymus organ culture with (2 samples for each category) or without (1 sample for each category) RANKL stimulation for 4 days under 2-DG. One µg of total RNA was used for library construction with TruSeq RNA Sample Prep Kit v2. THe ligated products were amplified using 8 cycles of PCR to generate RNA-seq library. Library integrity was verified by Bioanalyzer DNA1000 assay. Sequencing was performed in 101-bp paired-end mode using an Illumina HiSeq.Technical duplicate has done. Results: A total of 177,060,020 reads were obtained for 6 samples. Filtered reads were mapped to the UCSC mm10 using the TopHat program(v2.0.10) with the default parameters. The Cufflinks program (v2.1.1) was then used to assemble 22,448 transcripts and to calculate the fragments per kilobase of exon per million mapped fragments(FPKM) values, which are normalized measurement of gene expression levels(= genes-FPKM file).To identify differentially expressed genes, the ratio of the maximum FPKM to the minimum FPKM was compared among 6 samples. When the ratio was more than 3, the gene was regarded as being significantly altered in expression level. We added 0.1 to the FPKM value to avoid division by zero. This led us to identify 3212 genes with differential expression. Among these, the expression levels of 2536 genes were significantly associated with the RANKL treatment or Jmjd6 expression ( P value <0.05). Analysis for intron retention was performed as follows. According to the current gene annotation ("known genes" in UCSC mm10), there are 188,208 introns in total. As intron retention events should be observed in the genes with relatively high expression, we only focused on the genes with the maximum FPKM value more than 10 at least in one of the six samples. As a result, we obtained 84,708 introns. The reads mapped to these intronic regions were counted by the intersectBed program in the BEDTools utilities with -c option, and the counts are converted into the FPKM values for each intron (intronic FPKM). There are 1051 introns with intronic FPKM more than 10 in at last on of the six samples, and the degree of intron retention was calculated by dividing intronic FPKM value by conventional FPKM value for each gene (intron-FPKM file). Overall design: Samples were WT and Jmjd6-/- fetal thymus organ culture with (2 samples for each category) or without (1 sample for each category) RANKL stimulation for 4 days under 2-DG. One µg of total RNA was used for library construction with TruSeq RNA Sample Prep Kit v2. THe ligated products were amplified using 8 cycles of PCR to generate RNA-seq library.

Description
The pathways involved in hierarchical differentiation of human embryonic stem cells (hESC) into abundant and durable endothelial cells (EC) are unknown. We employed an EC-specific VE-cadherin promoter driving GFP (hVPr-GFP) to screen for factors that augmented yields of vascular-committed ECs from hESCs. In phase 1 of our approach, inhibition of TGFb, precisely at day 7 of hESC differentiation, enhanced emergence of hVPr-GFP+ ECs by 10-fold. In the second phase, TGFb-inhibition preserved proliferation and vascular identity of purified ECs, resulting in net 36-fold expansion of homogenous EC-monolayers, and allowing transcriptional profiling that revealed a unique angiogenic signature defined by the VEGFR2highId1highVE-cadherin+EphrinB2+CD133+HoxA9- phenotype. Using an Id1-YFP hESC reporter line, we showed that TGFb-inhibition sustained Id1 expression in hESC-derived ECs, which was required for increased proliferation and preservation of EC commitment. These data provide a multiphasic method for serum-free differentiation and long-term maintenance of authentic hESC-derived ECs, establishing clinical-scale generation of transplantable human ECs.
