Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Rcho-1 trophoblast stem cells can be maintained in a trophoblast stem cell state or induced to differentiate into trophoblast giant cells. During the differentiation process the PI3K pathway is constitutively activated.

Description
In hemochorial placentation, trophoblast stem cells differentiate into multiple lineages to aquire specific functions, such as invasive and endocrine phenotype. FOSL1 has been identified as a key regulator for trophoblast differentiation. We used microarray to detail mechanisms underlying FOSL1 signaling pathway in trophoblast differentiation.

Description
We had previously discovered that the transcription factor OVO-like 1 (OVOL1) was highly induced during trophoblast differentiation. In this study, we used an lentiviral shRNA strategy to decrease OVOL1 expression in BeWo trophoblast cells. Control cells were transduced with shRNAs targeting no known mammalian transcript (shCont). Following stimulation of differentiation (48h exposure to 8-bromo-cyclic adenosine monophosphate), a RNA-seq approach was used to determine global transcript differences in OVOL1-knockdown cells compared to control cells. Overall design: Trophoblast cells transduced with control shRNAs were used as controls. Cells transduced with shRNAs targeting OVOL1 were used as treatment. All cells received 250 uM 8-bromo-cyclic adenosine monophosphate to stimulate differentiation. Three independent replicates of control and treatment groups were analyzed.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
BeWo trophoblast cells differentiate in response to expsure to cyclic adenosine monophosphate (cAMP) analogs. Differentiation includes syncytialization (fusion) and hormonogenesis. The goal of this study was to globally determine transcripts differentially expressed in BeWo trophoblast cells following a 24-h exposure to 250 uM 8-bromo-cAMP.

Description
Placentation differs in the BN rat strain when compared to HSD and DSS rat strains. Intrauterine trophoblast invasion is shallow and the junctional zone is underdeveloped in the BN rat. These structural differences are striking but their quantification is not conducive to high throughput analyses. In the rat, the junctional zone can be readily dissected and is more homogenous than other components of the placentation site. HSD and BN rat gestation day 18.5 junctional zone gene expression profiles were determined using DNA microarray analysis to identity placenta-associate quantitate traits.

Description
Bovine papillomavirus (BPV) is the causative agent of papillomatosis in cattle. The disease causes cutaneous and mucosal lesions that can be minimized or lead to the appearance of malignant tumors. This study aims to identify possible molecular mechanisms that are behind the pathological processes associated with bovine papillomatosis through the identification of genes related to the development of the lesions. For this, next-generation RNA sequencing was used to assess differentially expressed genes in infected by BPV and non-infected bovines. Three animals with papillomatosis lesion and three without papillomatosis lesion were studied. The Galaxy platform was used to analyze the data generated by the sequencing. The Illumina output files were converted to FASTQ format. Quality evaluation was performed using FastQC and the sequence quality cut was performed using Trimmomatic. TopHat and Bowtie were used to map and align the reads with the reference genome. The abundance of the expressed genes was verified using Cuffilinks. Cuffdiff was used for differential expression analysis. Functional annotation of the differentially expressed genes was performed using Gene Ontology (GO) databases. RNA-sequencing generated a total of 121,722,238 of reads. In the gene expression analysis, a total of 13,421 genes expressed were identified and of these 1343 were differentially expressed. The functional annotation of differentially significant genes showed that many genes presented functions or they were related to metabolic pathways associated with the progression of papillomatosis lesions and cancer development in cattle. Although more studies are needed, this is the first study that focused on a large-scale evaluation of gene expression associated with the BPV infection, which is important to identify possible mechanisms regulated by the host genes that are necessary the development of the lesion Overall design: Analysis of three BPV infected and three BPV non-infected samples

We had previously discovered that the transcription factor Cited2 was highly induced during trophoblast differentiation. In this study, we used an lentiviral shRNA strategy to decrease Cited2 expression in Rcho-1 trophoblast cells. A RNA-seq approach was used to determine global transcript differences inRcho-1 knockdown cells compared to control cells. Overall design: Rcho-1 cells transduced with control shRNAs were used as controls. Cells transduced with shRNAs targetingCited2 were used as treatment.Cells were differentiated for 8 days and the analyses were done.

Description
Recently, we described a new animal model of CNS primitive neuroectodermal tumors (CNS-PNET), which was generated by orthotopic transplantation of human Radial Glial (RG) cells into NOD-SCID mice’s brain sub- ventricular zone. In the current study we conducted comprehensive RNA-Seq analyses to gain some insights on the mechanisms underlying tumorigenesis in this mouse model of CNS-PNET. Here we show that the RNA-Seq profiles derived from these tumors cluster with those reported for patients’ PNETs. Overall design: RNA-seq of tumors from central nervous system primitive neuroectodermal tumor (CNS PNET) animal model
