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. 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.

Description
Acquisition of the lower jaw (mandible) was evolutionarily important for jawed vertebrates. In humans, syndromic craniofacial malformations often accompany jaw anomalies. Hand2 is involved in coordinating the developmental network of mandibles and the oral apparatus through Hand2-downstream genes and is therefore a major determinant of jaw identity.
Publication Title
Specification of jaw identity by the Hand2 transcription factor.

Description
Sympathetic neurons of SCG (Superior Cervical Ganglia) send axonal projections either along the external carotid arteries to innervate the salivary glands, or along the internal carotid arteries to the lacrimal and pineal glands, the eye, blood vessels and skin of the head, and the mucosa of the oral and nasal cavities. Previous studies using Wnt1Cre and R26R have defined the neural crest and mesodermal origins of vascular smooth muscle in the heart outflow tract and great vessels, although not specifically of the segments that are relevant for the projections of the SCG neurons. The third pharyngeal arch arteries are lined by neural crest-derived smooth muscle, and consequently, their derivatives, including the entirety of the external carotid arteries and only the base of the internal carotid arteries, also have a neural crest origin. In contrast, the dorsal aortae are lined by smooth muscle that is mesodermal in origin, and as a result, the internal carotid arteries from just above their origination from the common carotid arteries have a mesoderm-derived smooth muscle layer. To address the possibility that guidance cues for SCG neurons are selectively expressed by the external carotid vs. the internal carotid arteries, we isolated these segments of the vasculature from mouse embryos at E13.5 and extracted RNA to screen microarrays for differentially expressed genes.

Total RNA was extracted using TRI® Reagent (Sigma). cDNA was synthesized by RevertAid™ First Strand cDNA Synthesis Kit with Oligo dT primers (K1622, Fermentas) following manufacturer’s recommendations. PCR reactions were carried out on a DNAEngine® Thermal Cycler (PTC-0200G, Bio-Rad) in 25 µl reaction volume containing 1 µl cDNA, 200 nM primer pairs and components of TaKaRa Taq™ kit (R001A, Takara). All samples were analyzed in triplicate RT-qPCR.mRNAs were extracted using biotinylated poly(dT) oligo, followed by further removing of contaminated rRNA using RiboMinus Transcriptome Isolation Kit (K1550-02, Invitrogen). Then mRNAs were fragmented into 100-200nt length and subjected to immunoprecipitation with m6A specific antibody.The libraries were sequenced using HiSeq2000 (Illumina) in single-read mode, creating reads with a length of 101 bp. Sequencing chemistry v2 (Illumina) was used and samples were multiplexed in two samples per lane.

Klf5 has essential functions during early embryogenesis and in the derivation of ES cells from inner-cell mass of blastocyst. Among Kruppel-like factor (Klf) family members, only Klf5 shows peri-implantation lethal phenotype, but the precise mechanisms still remain unknown. To understand and identify molecular mechanisms, we performed microarray analysis by using E3.0 WT and Klf5 KO embryos when first phenotype of Klf5 deficiency appears.
