Description
We performed a transcriptome-wide study to compare gene expression profiles of ECFC, human coronary artery endothelial cells (HCAEC) and human umbilical vein endothelial cells (HUVEC) utilising subcutaneous adipose tissue-derived stromal vascular fraction (SAT-SVF) as a negative control population. Baseline gene expression in ECFC fully corresponds to their endothelial specification and may contribute to the basement membrane organisation, fulfilling the requirements for the suitable cell population for in vitro pre-endothelialisation of tubular scaffolds. Overall design: Comparison of gene expression in 4 cell types by Hiseq sequencing.

Description
The mammalian telomere-binding protein Rap1 was found to have additional non-telomeric functions, acting as a transcriptional cofactor and a regulator of the NF-kB pathway. Here, we assess the effect of disrupting mouse Rap1 in vivo, and report on its unanticipated role in metabolic regulation and body weight homeostasis. Rap1 inhibition causes dysregulation in hepatic as well as adipose function. In addition, using a separation-of-function allele, we show that the metabolic function of Rap1 is independent of its recruitment to TTAGGG binding elements found at telomeres, and at other interstitial loci.

Description
Purpose: Transcriptome is the entire repertoire of all transcripts present in a cell at any particular time. We undertook next-generation whole transcriptome sequencing approach to gain insight of the transcriptional landscape of the developing mouse lens. Methods: We ascertained mice lenses at six developmental time points including two embryonic (E15 and E18) and four postnatal stages (P0, P3, P6, and P9). The ocular tissue at each time point was maintained as two distinct pools serving as biological replicates for each developmental stage. The mRNA and small RNA libraries were paired-end sequenced on Illumina HiSeq 2000 and subsequently analyzed using bioinformatics tools. Results: Mapping of mRNA and small RNA libraries generated 187.56 and 154.22 million paired-end reads, respectively. We detected a total of 14,465 genes in the mouse ocular lens. Of these, 46 genes exhibited 40-fold differential expression compared to transcriptional levels at E15. Likewise, small RNA profiling identified 379 microRNAs (miRNAs) expressed in mouse lens. Of these, 49 miRNAs manifested an 8-fold or higher differential expression when compared, as above to the microRNA expression at E15. Conclusion: We report the first comprehensive profile of developing murine lens transcriptome including both mRNA and miRNA through next-generation RNA sequencing. A complete repository of the lens transcriptome of six developmental time points will be monumental in elucidating processes essential for development of the ocular lens and maintenance its transparency. Overall design: Whole transcrtiome and microRNA profilling of mouse lens using 2 embryonic (E15 and E18) and 4 postnatal stages (P0, P3, P6 and P9) in duplicates through high-throughput sequening using Illumina HiSeq2000.

Description
FOXE3 is a lens specific transcription factor that has been associated with anterior segment ocular dysgenesis. To determine the transcriptional target(s) of FOXE3 that are indispensable for the anterior segment development, we examined the transcriptome and the proteome of cells expressing truncated FOXE3 responsible for Peters anomaly identified through linkage-coupled next-generation whole exome sequencing. We found that DNAJB1, an autophagy-associated protein, was the only candidate exhibiting differential expression in both screens. We confirmed the candidacy of DNAJB1 through chromatin immunoprecipitation and luciferase assays while knockdown of DNAJB1 in human lens epithelial cells resulted in mitotic arrest. Subsequently, we targeted dnajb1a in zebrafish through injection of a splice-blocking morpholino. The dnajb1a morphants exhibited underdeveloped cataractous lenses with persistent apoptotic nuclei. In conclusion, we have identified DNAJB1 as a transcriptional target of FOXE3 in a novel pathway that is crucial for development of the anterior segment of the eye. Overall design: Human Embryonic Kidney (HEK293FT) cells were transfected with the expression vector (pT-RexTM-DEST30) harboring either the wild type or the mutant (C240*) FOXE3 ORF (open reading frame). The experimental design included a total of eight biological replicates of cells expressing the wild type and eight replicates of mutant FOXE3 along with eight non-transfected controls. Cells were harvested 24-hour post-transfection and subjected to total RNA isolation for the preparation of whole transcriptome next-generation sequencing libraries. Initially, we examined the quality of transcriptome libraries on a MiSeq genome analyzer. Subsequent to confirmation of the quality, all libraries were paired-end sequenced (2 x 100 bp) using Illumina TruSeq Cluster V3 flow cell at a concentration of 13.0 pM in two separate lanes (12 bar-coded mRNA pooled libraries in each lane) on a HiSeq 2000 genome analyzer.

Description
Genome-wide association studies (GWAS) have been pivotal to increasing our understanding of intestinal disease. However, the mode by which genetic variation results in phenotypic change remains largely unknown, with many associated polymorphisms likely to modulate gene expression. Analyses of expression quantitative trait loci (eQTL) to date indicate that as many as 50% of these are tissue specific. Here we report a comprehensive eQTL scan of intestinal tissue.

Description
The involvement of skeletal muscle in the process of palatal development in mammals is an example of Waddingtonian epigenetics. Our earlier study showed that the cleft palate develops in the complete absence of skeletal musculature during embryonic development in mice. This contrasts with previous beliefs that tongue obstruction prevents the elevation and fusion of the palatal shelves. We argue that the complete absence of mechanical stimuli from the adjacent muscle, i.e., the lack of both static and dynamic loading, results in disordered palatogenesis. We further suggest that proper fusion of the palatal shelves depends not only on mechanical but also on paracrine contributions from the muscle. The muscle's paracrine role in the process of palatal fusion is achieved through its being a source of certain secreted and/or circulatory proteins.

Description
Skeletal (striated) muscle is one of the four basic tissue types, together with the epithelium, connective and nervous tissues. Lungs, on the other hand, develop from the foregut and among various cell types contain smooth, but not skeletal muscle. Therefore, during earlier stages of development, it is unlikely that skeletal muscle and lung depend on each other. However, during the later stages of development, respiratory muscle, primarily the diaphragm and the intercostal muscles, execute so called fetal breathing-like movements (FBMs), that are essential for lung growth and cell differentiation. In fact, the absence of FBMs results in pulmonary hypoplasia, the most common cause of death in the first week of human neonatal life. Most knowledge on this topic arises from in vivo experiments on larger animals and from various in vitro experiments. In the current era of mouse mutagenesis and functional genomics, it was our goal to develop a mouse model for pulmonary hypoplasia.

This study describes a cDNA microarray analysis that compared developing mouse MyoD-/- limb musculature (MyoD-dependent, innervated by Lateral Motor Column motor neurons) and Myf5-/- back (epaxial) musculature (Myf5-dependent, innervated by Medial Motor Column motor neurons) to the control and to each other, at embryonic day 13.5 which coincides with the robust programmed cell death of motor neurons and the inability of myogenesis to undergo its normal progression in the absence of Myf5 and MyoD that at this embryonic day cannot substitute for each other.
