View SamplesHere, we characterize differential expression patterns associated with two chromosomal inversions found in natural Drosophila melanogaster populations. To isolate the impacts of genome structure, we engineered synthetic chromosomal inversions on controlled genetic backgrounds with breakpoints that closely match each natural inversion.

View SamplesTo investigate the basic principles of epigenetic control, we established an orthogonal epigenetic regulatory system in mammalian cells using N6-methyladenine (m6A), a DNA modification not commonly found in metazoan epigenomes. We developed a synthetic initiator module (synI) capable of establishing m6A marks in a sequence-specific manner at designer reporter loci integrated in the human genome, and a synthetic readout module (synR) which selectively reads m6A and consequently induces transcriptional changes. To ensure our orthogonal m6A system has minimal interaction with endogenous human transcriptional machineries, we performed RNA-sequencing analysis and determined that both synI and synR expression have minimal effect on 293FT transcriptome.

View SamplesRecent advancements in cell-based therapies for the treatment of cardiovascular disease (CVD) show continuing promise for the use of transplanted stem and cardiac progenitor cells (CPCs) to promote cardiac restitution. However, a detailed understanding of the molecular mechanisms that control the development of these cells remains incomplete and is critical for optimizing their use in such therapy. Long non-coding (lnc) RNA has recently emerged as a crucial class of regulatory molecules involved in directing a variety of critical biological and cellular processes including development, homeostasis and disease. As such, a rising body of evidence suggests that they also play key regulatory roles in CPC development, though many questions remain regarding the expression landscape and specific identity of lncRNA involved in this process. To address this, we performed whole transcriptome sequencing of two murine CPC populations – Nkx2-5 EmGFP reporter-sorted embryonic stem (ES) cell-derived and ex vivo, cardiosphere-derived – in an effort to characterize their lncRNA profiles and potentially identify novel CPC regulators. The resulting sequencing data revealed an enrichment in both CPC populations for a panel of previously-identified lncRNA genes associated with cardiac differentiation. Additionally, a total of 1,678 differentially expressed and as-of-yet unannotated, putative lncRNA genes were found to be enriched for in the two CPC populations relative to undifferentiated ES cells.

View SamplesThe 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.
