Illumina HiSeq 2500
Description
Illumina sequencing was used to assay the effect of mifepristone treatment on gene expression in adult Drosophila, including males, virgin females and mated females. Overall design: Males of strain w[1118]; p53B[6] were crossed to virgins of w[1118]; rtTA(3)E2 and progeny males and virgins were collected over 48 hours. One half of the virgins were mated to w[1118] males at ratio of 1:1 virgins to males for 4 days. Mated females were then separated from the w[1118] males. The mated females, males and virgins females were then maintained at approximately 20 flies per vial, on food with and without supplementation with 160ug/ml mifepristone for 12 days. Total fly RNA was isolated from 20 animals per sample. Three replicate samples were generated for each type of flies: males, mated females and virgin females.

Affymetrix Chicken Genome Array (chicken)
Description
While infection of chickens with highly pathogenic avian influenza (HPAI) H5N1 subtypes often leads to complete mortality within 24 to 48 h, infection of ducks in contrast causes mild or no clinical signs. Rapid onsets of fatal disease in chickens, but with no evidence of severe clinical symptoms in ducks, suggest underlying differences in their innate immune mechanisms. To understand the molecular basis for such difference, chicken and duck primary lung cells, infected with a low-pathogenicity avian influenza (LPAI) and two HPAI H5N1 viruses, were subjected to RNA expression profiling using Affymetrix Chicken GeneChip arrays.
Publication Title
Highly pathogenic avian influenza virus infection in chickens but not ducks is associated with elevated host immune and pro-inflammatory responses.

Description
RNA seq analysis was conducted to determine gene expression in the day 14 ovine conceptus. This was used in conjunction with the day 14 PPARG ChIP-seq analysis to identify genes bound by PPARG which were also expressed or not expressed in the day 14 conceptus. Understanding changes in gene expression during early pregnancy is critical to improving fertility and reproductive efficiency in ruminants. Overall design: RNA seq analysis of 4 conceptuses from 4 individual Day 14 pregnant columbia/rambouillet crossbred ewes

Description
Roux-en-Y gastric bypass (RYGB) is the most effective therapy for morbid obesity, but it has a ~20% failure rate. We used our established RYGB model in diet-induced obese (DIO) Sprague-Dawley rats, which reproduces human bi-phasic body weight (BW) loss pattern, to determine mechanisms contributing to success (RGYB-S) or failed (RYGB-F) RYGB. DIO rats were randomized to RYGB, sham operated Obese, and sham operated obese pair fed-linked to RYGB (PF) groups. BW, caloric intake (CI) and fecal output (FO) were recorded daily for 90 days, food efficiency (FE) was calculated, and morphologic changes were determined. Gut, adipose and thyroid hormones were measured in plasma. Mitochondrial respiratory complexes in skeletal muscle, expression of energy-related hypothalamic and fat peptides, receptors and enzymes were quantified. A 25% failure rate occurred. RYGB-S, RYGB-F and PF rats vs. Obese showed rapid BW decrease, followed by sustained BW loss in RYGB-S. RYGB-F and PF gradually increased BW. Expression profiling of both CNS (hypothalamus) and peripheral tissues (subcutaneous abdominal fat) strongly supported the involvement of a number of metabolic and feeding-related genes in the differential outcomes.

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
By transcriptome (RNA-Seq) analysis of PC-3 or DU145 prostate cancer cell lines over- or under-expressing NUSAP1, we determined genes that become differentially expressed upon expression changes of NUSAP1. Ingenuity Pathway Analysis revealed that the differentially expressed genes correlated with increased tumor progression and are involved in functions that include cancer, cellular movement, and cell morphology Overall design: Lentiviral infections were used to over- or under-express NUSAP1 or controls in triplicate in PC-3 or DU145 cell lines. Seventy-two or ninety-six hours after infection, total RNA was extracted and purified. The sequencing libraries were prepared with the TruSeq RNA Sample Preparation Kit v2 (Illumina) or TruSeq Stranded mRNA Sample Preparation Kit (Illumina) as directed by the manufacturer’s protocol. Pooled libraries were run on a Hiseq 2000 Sequencing System (Illumina) with 101 base pair single-end reads.
