Description
Inactivating mutations in SMARCA4 (BRG1), a key SWI/SNF chromatin remodelling gene, underlie small cell carcinoma of the ovary, hypercalcemic type (SCCOHT). To reveal its druggable vulnerabilities, we perform kinase-focused RNAi screens and uncover that SMARCA4-deficient SCCOHT cells are highly sensitive to the inhibition of cyclin-dependent kinase 4/6 (CDK4/6). SMARCA4 loss causes profound downregulation of cyclin D1, which limits CDK4/6 kinase activity in SCCOHT cells and leads to in vitro and in vivo susceptibility to CDK4/6 inhibitors. SCCOHT patient tumors are deficient in cyclin D1 yet retain the retinoblastoma-proficient/p16INK4a-deficient profile associated with positive responses to CDK4/6 inhibitors. Thus, our findings indicate that CDK4/6 inhibitors, approved for a breast cancer subtype addicted to CDK4/6 activation, could be repurposed to treat SCCOHT. Moreover, our study suggests a novel paradigm whereby critically low oncogene levels, caused by loss of a driver tumor suppressor, may also be exploited therapeutically. Overall design: The effect of CDK6 knockdown and palbociclib treatment on SCCOHT cells.

Affymetrix Chicken Genome Array (chicken)
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
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
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.

- Affymetrix Vitis vinifera (Grape) Genome Array (vitisvinifera)
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
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.

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.
