Description
RNA seq analysis of laser capture microdissected luminal and glandular epithelium from ewes on day of pregnancy 10, 12, 14, 16 and 20. As well as RNA seq of whole conceptuses, and trophectoderm tissue from day 12, 14, 16 and 20 of pregnancy. Determination of gene expression changes in the uterine epithelium and conceptus during early pregnancy helps to improve our understanding of early pregnancy events and provides a basis of new strategies to improve fertility and reproductive efficiency in ruminants. Overall design: RNA seq analysis of 4 samples of each tissue type (luminal epithelium (LE), glandular epithelium (GE) and conceptus) for 4 animals. Pre-sequencing amplification of LE, GE and day 12 conceptus samples.

Description
This study relates to pregnancy outcome after assisted reproduction of fertility-classified cattle. The aim is to investigate how the uterine environment impacts and programs conceptus survival and development. The study found that ripple effects of dysregulated conceptus-endometrial interactions elicit post-elongation pregnancy loss in subfertile animals during the implantation period. Overall design: Heifer cows classified as high fertile (HF), subfertile (SF), or infertile (IF) were investigated. The RNA-seq analysis was performed for endometrium samples at day 17 of pregnancy. For comparison, non-pregnant cows were included in the analysis. RNA from conceptus of HF and SF pregnant animals (day 17) were also included in the RNA-seq analysis. A total of 25 endometrium samples (5 non-pregnant of each fertilty group, 5 pregnant HF, and 5 pregnant SF) and 27 conceptus samples (10 SF and 17 HF) were used in the RNA-seq analysis.

Description
We report a pilot investigation for poly-A RNAs differentially expressed during Mycobacterium tuberculosis infection. Participation in this investigation from March 2010 to July 2013 was voluntary, only subjects that were >18 years old and that informed written consent were considered eligible. The recruitment of tuberculosis (TB) patients was done at public hospitals in Rio de Janeiro, Brazil. The diagnostic criteria for active pulmonary tuberculosis was at least one AFB (acid-fast bacilli) -positive sputum sample for M. tuberculosis and/or positive sputum culture and/or compatible clinical evolution for pulmonary TB and less than 15 days of anti-TB treatment and was in accordance with those of the Brazilian Ministry of Health. Blood was collected from recent close contacts (rCt) and active tuberculosis (TB) index cases (n=6). Latent TB infection (LTBI) was accessed by both tuberculin skin test (TST, cut-off = 5mm) and in house interferon-gamma release assays (IGRA, cut-off = 100 pg/ml), therefore, 12 rCt were classified as uninfected controls and 16 with LTBI. Subsequently, the sequencing was performed following the standard protocols on Illumina HiSeq® 2500 Sequencing System (Illumina, San Diego, CA) running 100 bp paired-end reads (PE100) and generating approximately 30 million reads passing filter for each sample to produce the mRNA reads. Mining these RNAseq data, highly prominent modulation of DOCK9, EPHA4, and NPC2 mRNA expression was observed in the TB samples, indicating that they might have a role in TB pathogenesis. These differential modulations upon M. Tuberculosis infection were further validated by additional evidences in larger cohorts from different geographical areas. Overall design: We collected blood samples from the recent close contacts (rCt) at the recruitment and monitored them for 1-year. All TB participants were treatment-naïve. An infection mRNA signature was derived from whole blood RNA sequencing data by comparing TB and uninfected rCt. We selected the 3 most prominent genes, by area under the ROC curve analysis, for additional validations. Some of the LTBI participants also showed the mRNA infection profile.

- Illumina mouse-6 v1.1 expression beadchip
Description
Skeletal muscle actin mice (Crawford et al., (2002) Mol Cell Biol 22, 5587) were crossed with cardiac actin transgenic mice (termed "ACTC^Coco" or "Coco" for short), to produce mice that had cardiac actin instead of skeletal muscle actin in their skeletal muscles (termed "ACTC^Co/KO" or for short "Coco/KO"). Microarray analysis using the Illumina mouse-6 v1.1 expression beadchip was performed on RNA extraced from the soleus muscle of Coco/KO mice and wildtype mice, to confirm the swith in actin isoform expression, and to determine what other differences might exist between wildtype mice and the Coco/KO mice.

Description
Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare NGS-derived skin transcriptome profiling (RNA-seq) to determine pathways and networks dependent on retinoic acid during skin development. Methods: Skin mRNA profiles of embryonic day E16.5 wild-type (WT) and Cyp26b1 knockout (Cyp26b1-/-), and of control and of dermal and epidermal skin fractions of Engrailed1cre;Cyp26b1f/- (En1cre;Cyp26b1f/-) conditional knockout mice were generated by deep sequencing, in duplicate, using Illumina HiSeq2000. The sequence reads that passed quality filters were analyzed at the transcript isoform level by ANOVA (ANOVA) and TopHat. qRT–PCR validation was performed using TaqMan and SYBR Green assay. Results: RNA-Seq data were generated with Illumina’s HiSeq 2000 system. Raw sequencing data were processed with CASAVA 1.8.2 to generate fastq files. Reads of 50 bases were mapped to the mouse transcriptome and genome mm9 using TopHat 1.3.2. Gene expression values (RPKM) were calculated with Partek Genomics Suite 6.6, which was also used for the ANOVA analysis to determine significantly differentially expressed genes. Conclusions: Our study represents the first detailed analysis of Cyp26b1-/- skin and En1cre;Cyp26b1f/- dermis/epidermic transcriptomes, with biologic replicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. We conclude that RNA-seq based transcriptome characterization would expedite genetic network analyses and permit the dissection of complex biologic functions. Overall design: Skin mRNA profiles of embryonic-day 16.5 wild type (WT) and Cyp26b1-/- mice and of dermis and epidermis of embryonic day 18.5 control and En1cre;Cyp26b1f/- were generated by deep sequencing, in duplicate, using Illumina HiSeq2000.
