Description
Smooth muscle cell (SMC) phenotypic switching from a contractile to a synthetic state is implicated in diverse vascular pathologies, including neointimal formation. This study was designed to identify lncRNAs that may play a role in vascular pathologies. Primary smooth muscle cells cultured from surplus human saphenous vein tissue were treated with inflammatory and proliferative stimuli, IL1a and PDGF, for 72h and RNA extracted for RNA-sequencing. Using edgeR processed data we found expression of many lncRNAs was altered following treatment and could play a role in vascular disease. Overall design: 4 groups of samples, n= 3/group each replicate using cells cultured from a different venous patient sample. Cells were quiesced in 0.2% serum for 48h followed by addition of 10ng/ml IL1a , 20ng/ml PDGF or both 10ng/ml IL1a and 20ng/ml PDGF together. Cells were collected after 72h and RNA extracted using Qiagen RNeasy kits. RNA-sequencing was carried out by Beckman Coulter Genomics on the r-RNA depleted fraction.

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
REST is a master regulator of genes that are involved in the acqusition of neuronal fate. The role of REST is not well understood so we attempted to investigate the role of REST in the development of neural cells by analysing the genes that are upregulated when REST is knocked down via shRNA

REST regulates the pool size of the different neural lineages by restricting the generation of neurons and oligodendrocytes from neural stem/progenitor cells.

Description
To characterize the role of the circadian clock in mouse physiology and behavior, we used RNA-seq and DNA arrays to quantify the transcriptomes of 12 mouse organs over time. We found 43% of all protein coding genes showed circadian rhythms in transcription somewhere in the body, largely in an organ-specific manner. In most organs, we noticed the expression of many oscillating genes peaked during transcriptional rush hours preceding dawn and dusk. Looking at the genomic landscape of rhythmic genes, we saw that they clustered together, were longer, and had more spliceforms than nonoscillating genes. Systems-level analysis revealed intricate rhythmic orchestration of gene pathways throughout the body. We also found oscillations in the expression of more than 1,000 known and novel noncoding RNAs (ncRNAs). Supporting their potential role in mediating clock function, ncRNAs conserved between mouse and human showed rhythmic expression in similar proportions as protein coding genes. Importantly, we also found that the majority of best-selling drugs and World Health Organization essential medicines directly target the products of rhythmic genes. Many of these drugs have short half-lives and may benefit from timed dosage. In sum, this study highlights critical, systemic, and surprising roles of the mammalian circadian clock and provides a blueprint for advancement in chronotherapy.

Description
Alterations in the presence of sperm RNAs have been identified using microarrays in teratozoospermic (abnormal morphology) or other types of infertile patients. However, so far no studies had been reported on the sperm RNA content using microarrays in asthenozoospermic patients (low motility).

Description
The nuclear receptor HNF4A regulates embryonic and post-natal hepatocyte gene expression. Using hepatocyte-specific inactivation in mice, we show that the TAF4 subunit of TFIID acts as a cofactor for HNF4A in vivo and that HNF4A interacts directly with the TAF4-TAF12 heterodimer in vitro. In vivo, TAF4 is required to maintain HNF4A-directed embryonic gene expression at post-natal stages and for HNF4A-directed activation of post-natal gene expression. TAF4 promotes HNF4A occupancy of functional cis-regulatory elements located adjacent to the transcription start sites of post-natal expressed genes and for pre-initiation complex formation required for their expression. Promoter-proximal HNF4A-TFIID interactions are therefore required for pre-initiation complex formation and stable HNF4A occupancy of regulatory elements as two concomitant mutually dependent processes. Overall design: RNA profiles in wild-type and Taf4-/- livers by deep sequencing

Description
Mice lacking the beta 2 subunit (Chrnb2) of the neuronal nicotinic acetylcholine receptor display altered retinal waves and disorganized projections of the retinal ganglion cells to the lateral geniculate nucleus (LGN). mRNA populations from retinas and LGN from Chrnb2-/-and wild type (C57BL/6J) mice were compared at 4 days postnatal, when RGC segregation to the LGN begins in WT mice. Retinal mRNAs were also compared at adulthood.

Description
CD44+/CD24- subpopulation of normal and cancerous breast epithelial cells are suggested to have stem cell properties. The goal of this study was to identify gene expression differences between CD44+/CD24- and CD44-/CD24+ subpopulation of cells from a same cell lines. We selected MCF-10A cells, which are immortalized derived from a fibrocystic breast disease. These cells are immortalized but not transformed and express basal cell markers.

Description
Rett syndrome (RTT) is a severe neurodevelopmental disorder that is caused by mutations in the gene methyl-CpG-binding-protein-2 (MECP2). However, the molecular mechanism by which these mutations mediate the RTT neuropathology remains enigmatic. In this study, we stimulated MeCP2-null cortical neurons (in vitro) and brains (in vivo) of a RTT mouse model to explore the effect of the loss of MeCP2 function on the activity-dependent transcriptomes of the cortex and hippocampus, respectively, using RNA-seq. These analyses revealed that the loss of MeCP2 results in aberrant global pattern of gene expression, characterized predominantly by higher levels of expression of activity-dependent genes, and anomalous alternative splicing events, specifically in response to neuronal activity. Overall design: For in vitro experiments, RNA-seq was performed on MeCP2-null (MT) and wild-type (WT) neuron-enriched cortical cultures that were either treated (T) with KCl for 3hr or not treated (N), after 10 days in culture. For in vivo experiments, RNA-seq was performed on hippocampi of MeCP2-null (MT) and wild-type (WT) mice that were either treated with kainic acid for 40 or 68 minutes, or not treated.
