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

Description
The conserved FACT (FAcilitates Chromatin Transcription) complex is a chromatin-reorganizing complex that promotes RNAPII transcription through chromatin templates by interacting with histones. It facilitates promoter activation by nucleosome eviction, and transcription elongation by nucleosome disruption and reassembly ahead and behind the RNAP. It also has a role in replication not fully understood yet. Genome-wide microarray analyses in spt16-11 and pob3-7 strains revealed a set of genes whose mRNA levels were altered with respect to the WT levels. These include 48 up-regulated and 80 down-regulated genes that are common to both strains. The up-regulated genes were longer and expressed at lower levels than the genome average whereas the down-regulated genes were more similar to the average of the genome.

Description
THO/TREX is a conserved complex with a role in messenger ribonucleoprotein biogenesis that links gene expression and genome instability. Here we show that human THO interacts with MFAP1, a spliceosome-associated factor. Interestingly, MFAP1 depletion impairs cell proliferation and genome integrity, increasing ?H2AX foci and DNA breaks. This phenotype is not dependent either on transcription or RNA-DNA hybrids. Mutations in the yeast orthologous gene SPP381, also confer a similar transcription-independent genome instability supporting a conserved role. MFAP1 depletion has a wide effect on splicing and gene expression in human cells, determined by transcriptome analyses, that affects a number of DNA damage response (DDR) genes, which supports an indirect role of MFAP1 on genome integrity. Our work defines a novel functional interaction between THO and RNA processing and argues that splicing factors may contribute to genome integrity indirectly by regulating the expression of DDR genes rather than by a direct role. Overall design: Analysis of gene expression in the Saccharomyces cerevisiae mutant spp381-ts under 1h of restrictive temperature.

Description
To determine whether an accelerated aging-like phenotype occurs in hematopoiesis of young Tif1?-/- mice (4 months old), we purified 200,000 hematopoietic stem cells (LSK: Lineage negative, Sca1+, c-Kit+) from Tif1?-/- mice and performed high-throughput mRNA sequencing (RNA-seq). We compared this transcriptome to physiological aging by creating two other RNAseq libraries from young (4 months old) and old (20 months old) wild type mice. Overall design: RNAseq study on young Tif1?-/- mice (4 months old), young wild type mice (4 months old) and old wild type mice (20 months old).

Description
The excessive perchlorate utilization as an oxidizer in rocket propellants and blasting agents had led to the contamination of surface and ground waters. This chemical is known to compete with iodine for binding to the thyroid membrane receptors potentially causing hypothyroidism and fetal retardation in pregnant women. Nevertheless, to date, its biological effects are not completely understood. We have investigated the molecular mechanisms responsive to perchlorate in the nematode C. elegans to nominate a candidate gene for further peruse in the development of a C.elegans perchlorate biosensor. Perchlorate (1 mg/mL) affected the transcriptional response of Regulation of developmental process, growth, defense mechanisms and stress response, among other biological processes.

Description
We report that the HF/HS-mediated functional enrichment of genes of immunity and inflammation is driven toward normal by the AOF supplementation Obesity may not constantly associate with metabolic disorders and mortality later in life, raising the challenging concept of healthy obesity. Here, high fat-high sucrose (HF/HS) feeding produces hyperglycaemia and hypercholesterolemia, increases oxidative stress, elevates endotoxemia, expands adipose tissue (with enlarged adipocytes, macrophage infiltration and accumulation of cholesterol and oxysterols), and reduces lifespan of obese mice. Despite persistence of obesity, supplementation with an antioxidant formulation normalizes plasma lipids and endotoxemia, prevents macrophage recruitment in adipose tissue, reduces adipose accumulation of cholesterol and cholesterol oxides, and extends lifespan. The HF/HS-mediated functional enrichment of genes of immunity and inflammation (in particular response to lipopolysaccharides) is driven towards normal by the antioxidant formulation. It is concluded that the limitation of immune cell infiltration in adipose tissue on the long term by an antioxidant formulation can increase lifespan independently of body weight and fat storage. It constitutes the hallmark of a healthy adiposity trait. Overall design: Examination of the expression profile of mice adipose tissues fed either standard (Std), High-fat/high-sucrose (HF/HS) or HF/HS + antioxidant formulation (AOF) for 180 days

Most FDA approved drugs are not equally effective in all patients, suggesting that identification of biomarkers to predict responders to a chemoprevention agent will be needed to stratify patients and achieve maximum benefit. The goal of this study was to investigate both patient specific and cell-context specific heterogeneity of metformin response, using cancer cell lines fibroblast cell lines and induced pluripotent stem cells differentiated into lung epithelial lineages.
