Description
Excessive accumulation of lipids in the adipose tissue is a major problem in the present-day broiler industry. However, few studies have analyzed the expression of adipose tissue genes that are involved in pathways and mechanisms leading to adiposity in chickens. Gene expression profiling of chicken adipose tissue could provide key information about the ontogenesis of fatness and clarify the molecular mechanisms underlying obesity.

Description
Salmonella species infect many vertebrate species, and pigs colonized with Salmonella enterica serovar Typhimurium (ST) are usually asymptomatic, making detection of these Salmonella-carrier pigs difficult. The variable fecal shedding of this gram-negative bacteria in such pigs is an important cause of foodborne illness and zoonotic disease. To investigate gene pathways and biomarkers associated with the variance in Salmonella shedding following experimental inoculation, we have initiated the first analysis of the whole blood transcriptional response induced by Salmonella. A population of pigs (n=40) was inoculated with ST and the peripheral blood and feces were collected between 2 and 20 days post-inoculation. Two groups of pigs with either low shedding (LS) or persistent shedding (PS) phenotypes were identified. The global transcriptional changes in response to ST inoculation were identified by Affymetrix Genechip?analysis of peripheral blood RNA at day 0 and day 2 post-inoculation.

Description
Cutaneous CD30+ lymphoproliferative disorder (CD30+LPDs), including lymphomatoid papulosis (LyP) and primary cutaneous anaplastic large-cell lymphoma (PCALCL), comprises the second most common group of cutaneous T cell lymphoma. Previously, we reported that special AT-rich sequence-binding protein1 (SATB1), a thymocyte specific chromatin organizer, was over-expressed and promoted malignant T-cell proliferation in a portion of CD30+LPDs, whereas other CD30+LPDs didn't express SATB1 at all. To elucidate the underlying molecular events in CD30+LPDs with differential SATB1 expression, we subjected 4 SATB1+ and 3 SATB1- CD30+LPDs skin biopsies to second-generation RNA-sequencing (RNA-seq). These data provide a significant resource for studies of CD30+LPDs. Overall design: 200ng total RNA samples were extracted and purified from 7 CD30+LPDs skin lesions (4 SATB1+, 3 SATB1-) to establish RNA library. Then the library was qualified through Agilent 2100 bioanalyzer instrument (Agilent Technologies, Santa Clara, CA) and Quantitative real-time polymerase chain reaction. The qualified library was sequenced on an Illumina HiSeqTM 2000 platform using paired-end reads. 10G raw data for each sample were obtained. The reads were aligned to the hg19 genome with SOAPaligner/SOAP2. Gene expression levels were calculated by reads per kilobase transcriptome per million mapped reads(RPKM)method.

Description
Haploid pluripotent stem cells, such as haploid embryonic stem cells (haESCs), facilitate the genetic study of recessive traits. In vitro, fish haESCs maintain haploidy in both undifferentiated and differentiated states, but whether mammalian haESCs can preserve pluripotency in the haploid state has not been tested. Here, we report that mouse haESCs can differentiate in vitro into haploid epiblast stem cells (haEpiSCs), which maintain an intact haploid genome, unlimited self-renewal potential, and durable pluripotency to differentiate into various tissues in vitro and in vivo. Mechanistically, the maintenance of self-renewal potential depends on the Activin/bFGF pathway. We further show that haEpiSCs can differentiate in vitro into haploid progenitor-like cells.

Description
Glioblastoma (GBM) is the most common and aggressive primary brain tumor in adults, with glioma initiating cells (GICs) implicated to be critical for tumor progression and resistance to therapy. KDM1B is involved in regulating GICs'' responses to hypoxia, since over-expression of KDM1B delays the cell growth under hypoxia while knocking-down of KDM1B in GICs promotes their survival and tumorigenic abilities. Overall design: We used RNA-Sequencing to detail the global change of gene expression in GICs with knockdown of KDM1B, and identified de-regulated genes and pathways downstream of KDM1B. CD133+ D456MG GICs were infected with non-targeting control and shRNA of KDM1B. Then RNA was extracted and gene expression was profiled by RNA-Seq.

Description
Solar ultraviolet CUV-Cradiation reaching the Earths surface is little due to the filtering effects of the stratospheric ozone layer. At present, artificial UV-C irradiation is utilized for different biological processes. Grape is a major fruit crop around the world. Research has shown that UV-C irradiation induced the biosynthesis of phenols. However, changes at the molecular level in response to UV-C and leading to these effects are poorly understood. To elucidate the effect of UV-C on expression of genes in grape and the response mechanism, transcript abundance of grape (Vitis vinifera L.) leaves was quantified using the Affymetrix Grape Genome oligonucleotide microarray (15,700 transcripts)

Description
The mechanistic target of rapamycin mTORC1 is a key regulator of cell metabolism and autophagy. Despite widespread clinical use of mTOR inhibitors, the role of mTORC1 in renal tubular function and kidney homeostasis remains elusive. By utilizing constitutive and inducible deletion of conditional Raptor alleles in renal tubular epithelial cells, we discovered that mTORC1 deficiency caused a marked concentrating defect, loss of tubular cells and slowly progressive renal fibrosis. Transcriptional profiling revealed that mTORC1 maintains renal tubular homeostasis by controlling mitochondrial metabolism and biogenesis as well as transcellular transport processes involved in counter-current multiplication and urine concentration. Although mTORC2 partially compensated the loss of mTORC1, exposure to ischemia and reperfusion injury exaggerated the tubular damage in mTORC1-deficient mice, and caused pronounced apoptosis, diminished proliferation rates and delayed recovery. These findings identify mTORC1 as an essential regulator of tubular energy metabolism and as a crucial component of ischemic stress responses. Pharmacological inhibition of mTORC1 likely affects tubular homeostasis, and may be particularly deleterious if the kidney is exposed to acute injury. Furthermore, the combined inhibition of mTORC1 and mTORC2 may increase the susceptibility to renal damage.

mTORC1 maintains renal tubular homeostasis and is essential in response to ischemic stress.

Description
Although the well-known importance of pig in agriculture, as well as a model for human biology, the miRNA catalog of pig has been largely undefined. Identification and preliminary characterization of adipose- and muscle-specific miRNAs would be a prerequisite for a thorough understanding of their roles in regulating adipose deposition and muscle growth. In the present study, we get insight into the miRNA transcriptome in eight adipose tissues, two skeletal muscles and cardiac muscle of pig using deep sequencing technology, and to elucidate their characteristic tissue-specific profiles and genomic context. Overall design: Eleven small RNA libraries from eight adipose tissues, two skeletal muscle tissues and cardiac muscle of pig were sequenced.
