Description
RNA-sequencing performed on petals and inflorescence of Arabidopsis plants. The study provides insight into the role of the TCP5 transcription factor and its molecular mechanism underlying petal growth, using knock-out, overexpression and induction lines on which RNA-sequencing was performed. Overall design: Analysis of differential gene expression using petals from TCP5 overexpression and knockout lines, as well as inflorescences of an inducible TCP5 mutant.

Description
The behavior of yeast cells during industrial processes such as the production of beer, wine and bioethanol has been extensively studied. By contrast, our knowledge about yeast physiology during solid state processes, such as bread dough, cheese or cocoa fermentation remains limited. We investigated changes in the transcriptome of three genetically distinct Saccharomyces cerevisiae strains during bread dough fermentation. Our results show that regardless of the genetic background, all three strains exhibit similar changes in expression patterns. At the onset of fermentation, expression of glucose-regulated genes changes dramatically, and the osmotic stress response is activated. The middle fermentation phase is characterized by the induction of genes involved in amino acid metabolism. Finally, at the latest time point, cells suffer from nutrient depletion and activate pathways associated with starvation and stress response. Further analysis shows that genes regulated by the High Osmolarity Glycerol (HOG) pathway, the major pathway involved in the response to osmotic stress and glycerol homeostasis, are among the most differentially expressed genes at the onset of fermentation. More importantly, deletion of HOG1 and other genes of this pathway significantly reduces fermentation capacity. Together, our results demonstrate that cells embedded in a solid matrix such as bread dough suffer severe osmotic stress, and that a proper induction of the HOG pathway is critical for an optimal fermentation.

Description
NZB/WF1 female mice spontaneously develop autoimmune lupus nephritis. Expression profiling of kidney tissue from (a) 12 week NZB/W F1 female mice defined as asymptomatic for lupus nephritis, (b) 36 and 42 week NZB/W F1 female mice defined as diseased/symptomatic for lupus nephritis and (c) 36 and 42 week NZB/W F1 female mice that are diseased/symptomatic for lupus nephritis and treated with Sirolimus was carried out. The goal of the study was to identify genes associated with lupus nephritis and modulated by Sirolimus, an inhibitor of mTOR. In addition, lupus nephritis genes resistant to Sirolimus therapy were also identfied

Description
Purpose: Next-generation sequencing (NGS) provides for quantitation of RNA abundances and comparison of RNA abundances within tissues and cells in a manner not possible with previous microarray technologies. We have made widespread use of Illumina sequencing technologies for RNA quantitation in several publications involving mouse hearts, dating from 2010, and wish to share both high-quality raw sequencing data and data processed to quantitate mRNA abundances from wild-type mice, male and female, at a variety of ages. These data will provide a resource for investigators using microarrays to understand the concentration of transcripts of interest relative to other cardiac RNAs, and will permit deeper interpretation of previous microarray studies. Overall design: 39 cardiac small RNA (microRNA) profiles of 4- to 16 week-old FVB/NJ wild type (WT) mice were generated on Illumina HiSeq 2000 instruments.

Description
Dysfunctional Parkin-mediated mitophagic culling of senescent or damaged mitochondria is a major pathological process underlying Parkinson disease and a potential genetic mechanism of cardiomyopathy. Despite epidemiological associations between Parkinson disease and heart failure, the role of Parkin and mitophagic quality control in maintaining normal cardiac homeostasis is poorly understood.We used germline mutants and cardiac-specific RNA interference to interrogate Parkin regulation of cardiomyocyte mitochondria and examine functional crosstalk between mitophagy and mitochondrial dynamics in Drosophila heart tubes. Overall design: 5 wild-type mouse hearts; 4 germline Parkin knockout mouse hearts Please note that the mouse cardiac examples were an adjunct to the Drosophila studies that comprised most of the associated publication. However, mRNA-sequencing was only performed on the mouse samples, not the Drosophila heart tubes.

Description
Background. Vaginal atrophy (VA) is the thinning of the vaginal epithelial lining, typically the result of lowered estrogen levels during menopause. Some of the consequences of VA include increased susceptibility to bacterial infection, pain during sexual intercourse, and vaginal burning or itching. Although estrogen treatment is highly effective, alternative therapies are also desired for women who are not candidates for hormone replacement therapy (HRT). The ovariectomized (OVX) rat is widely accepted as an appropriate animal model for many estrogen-dependent responses in humans; however, since reproductive biology can vary significantly between mammalian systems, this study examined how well the OVX rat recapitulates human biology at the transcriptional level. This report describes an analysis of expression profiling data, comparing the responses of rat and human vaginae to estrogen treatment. Results. The level of differential expression between pre- vs. post- estrogen treatment was calculated for each of the human and OVX rat datasets. Probe sets corresponding to orthologous rat and human genes were mapped to each other using NCBI Homologene. A positive correlation was observed between the rat and human responses to estrogen. Genes belonging to several biological pathways and GO categories were similarly differentially expressed in rat and human. A large number of the coordinately regulated biological processes are already known to be involved in human VA, such as inflammation, epithelial development, and EGF pathway activation. Conclusions. At the transcriptional level, there is evidence of significant overlap of the effects of estrogen treatment between the OVX rat and human VA samples.
