Description
Microarrays were used to evaluate the effects of azithromycin and an inflammatory stimulus (SMM) on human airway epithelium. Effects of azithromycin treatment were evaluated at 6, 24 and 48 hours. Effects of SMM were evaluated at 6 and 24 hours. In addition, pretreatment with azithromycin was used to evaluate the modulatory effects on SMM-induced inflammation. SMM=supernatant from microcorpulent material from human cystic fibrosis airways.
Publication Title
Azithromycin treatment alters gene expression in inflammatory, lipid metabolism, and cell cycle pathways in well-differentiated human airway epithelia.

Description
Implantation is dependent on synchronized interactions between the conceptus and surrounding decidual cells but the involvement of clock genes in this process is not well understood. Circadian oscillations are predicated on transcriptional-translational feedback loops, which balance the activities of the transcriptional activators CLOCK and BMAL1 and repressors encoded by PER and CRY genes. Here we show that loss of PER2 expression silences circadian oscillations in decidualizing human endometrial stromal cells (HESCs). Downregulation was preceded by reduced CLOCK binding to a noncanonical E-box enhancer in the PER2 promoter and occurred between 12 - 24 h after exposure to a deciduogenic stimulus. RNA sequencing revealed that premature inhibition of PER2 by siRNA knockdown leads to a grossly disorganised decidual response. Gene ontology analysis highlighted a preponderance of cell cycle regulators amongst the 1,121 genes perturbed upon PER2 knockdown. Congruently, PER2 inhibition abrogated mitotic expansion of differentiating HESCs by inducing cell cycle block at G2/M. Analysis of mid-luteal endometrial biopsies revealed an inverse correlation between PER2 transcript levels and the number of miscarriages in women suffering reproductive failure. Thus, PER2 synchronizes mitotic expansion of HESCs with a periodic decidual gene expression; uncoupling of these events may cause persistent pregnancy failure. Overall design: Endometrial mRNA profiles of paired control (siRNA-NT) and siRNA-PER2 were generated by deep sequencing, in triplicate using Illumina

Description
In order to try and identify characteristics of gene expression in the endometrium of women suffering infertility or recurrenty miscarriage, we performed RNAseq on endometrial pipelle biopsies from 20 women. The endometrial transcriptome in the mid-luteal phase of the cycle (window of implantation) is highly divergent in women suffering infertility or miscarriages. Overall design: 20 mid-luteal endometrial biopsies were analysed from infertile women and patients suffering recurrent pregnancy loss.Â

Description
Analysis of aldosterone-producing adenoma (APA) samples from patients with primary hyperaldosteronism. These APAs have a somatic mutation in either KCNJ5, CACNA1D, or ATP1A1. Results provide insight into the different mechanisms each mutation may cause leading to elevated aldosterone production in APA.

Description
Neuronal function critically depends on coordinated subcellular distribution of mRNAs. Disturbed mRNA processing and axonal transport has been found in spinal muscular atrophy and could be causative for dysfunction and degeneration of motoneurons. Despite the advances made in characterizing the transport mechanisms of several axonal mRNAs, an unbiased approach to identify the axonal repertoire of mRNAs in healthy and degenerating motoneurons has been lacking. Here we used compartmentalized microfluidic chambers to investigate the somatodendritic and axonal mRNA content of cultured motoneurons by microarray analysis. In axons, transcripts related to protein synthesis and energy production were enriched relative to the somatodendritic compartment. Knockdown of Smn, the protein deficient in spinal muscular atrophy, produced a large number of transcript alterations in both compartments. Transcripts related to immune functions, including MHC class I genes, and with roles in RNA splicing were upregulated in the somatodendritic compartment. On the axonal side, transcripts associated with axon growth and synaptic activity were downregulated. These alterations provide evidence that subcellular localization of transcripts with axonal functions as well as regulation of specific transcripts with nonautonomous functions is disturbed in Smn-deficient motoneurons, most likely contributing to the pathophysiology of spinal muscular atrophy.

Subcellular transcriptome alterations in a cell culture model of spinal muscular atrophy point to widespread defects in axonal growth and presynaptic differentiation.

Description
High-throughput mapping of cellular differentiation hierarchies from single-cell data promises to empower systematic interrogations of vertebrate development and disease. Here, we applied single-cell RNA sequencing to >92,000 cells from zebrafish embryos during the first day of development. Using a graph-based approach, we mapped a cell state landscape that describes axis patterning, germ layer formation, and organogenesis. We tested how clonally related cells traverse this landscape by developing a transposon-based barcoding approach (“TracerSeq”) for reconstructing single-cell lineage histories. Clonally related cells were often restricted by the state landscape, including a case in which two independent lineages converge on similar fates. Cell fates remained restricted to this landscape in chordin-deficient embryos. We provide web-based resources for further analysis of the single-cell data. Overall design: Single-cell mRNA sequencing of zebrafish embryonic cells. Samples1-7: Single cell libraries from untreated embryos (4-24 hours post-fertilization). Samples8-12: Single cell libraries from embryos injected with TracerSeq lineage cassette at the 1-cell stage. Samples13-18: Single cell libraries from embryos injected with sgRNA + Cas9 at the 1-cell stage.
