Description
We examined gene expression induced by Rhipicephalus microplus bites on host skin of tick-resistant and tick-susceptible breeds of bovines, Nelore and Holstein respectively, when they underwent a primary infestation.
Publication Title
Immune and biochemical responses in skin differ between bovine hosts genetically susceptible and resistant to the cattle tick Rhipicephalus microplus.

Description
Breast cancer is the most common cancer in women worldwide and metastatic dissemination is the principal factor related to death by this disease. Breast cancer stem cells, are thought to be responsible for metastasis and chemoresistance.. In this study, based on whole transcriptome analysis from putative breast CSCs and reverse-engineering of transcription control networks, we were able to identify two networks associated to this phenotype.

Description
Studies in human innate lymphoid cell (ILC) development are important in understanding the pathophysiology of immune deficiencies and providing insights into the design of immunotherapies for patients with cancer, infection, and autoimmune disease. Currently, it is unclear where and how ILCs develop in humans. The overall goal of our study is to gain a comprehensive understanding of the cellular and molecular components that regulate human ILC development and function in order to best understand how they work in physiological and pathological states.

Description
Over the last years, evidence has grown that exposure to air pollution, in addition to impairing lung function and health in individuals of all age, can be linked to negative effects in newborn when present during pregnancy. Data suggests that intrauterine exposure of fetuses (exposure of the mother to air pollution during pregnancy) in fact exerts a negative impact on lung development. However, the means by which exposure during pregnancy affects lung development, have not been studied in depth yet. In this study, we investigated alterations of the transcriptome of the developing lung in a mouse model of gestational and early-life postnatal exposure to urban PM2.5 (from Sao Paulo, Brazil).
Publication Title
Pre- and postnatal exposure of mice to concentrated urban PM<sub>2.5</sub> decreases the number of alveoli and leads to altered lung function at an early stage of life.

Description
Malaria, caused by Plasmodium parasites is responsible for the illness of millions of individuals each year. Plasmodium sporozoites inoculated by mosquitoes migrate to the liver and infect hepatocytes prior to release of merozoites that initiate symptomatic blood-stage malaria. Parasites are thought to be restricted to hepatocytes throughout this obligate liver-stage of replication and differentiation. In contrast to this notion, we found that a subset of hepatic CD11c+ cells co-expressing F4/80, CD103, CD207 and CSF1R, acquired a substantial parasite burden during the liver-stage of malaria, but only after initial hepatocyte infection. These CD11c+ cells found in the infected liver and liver-draining lymph nodes exhibited transcriptionally and phenotypically enhanced antigen-presentation functions; and primed protective CD8 T cell responses against Plasmodium liver-stage restricted antigens. Our findings uncover a novel aspect of Plasmodium biology as well as the fundamental mechanism by which CD8 T cell responses are primed against liver-stage malaria.

Description
Actively proliferating cells must constantly monitor and re-adjust their metabolic pathways to ensure phospholipid homeostasis for the replenishment of membranes and intracellular trafficking. Multiple studies have suggested that the lysine acetyltransferase NuA4 has a role in fine-tuning phospholipid metabolism in Saccharomyces cerevisiae, however the role of NuA4 in phospholipid homeostasis remains poorly defined. NuA4 mutants have increased gene expression of inositol-3-phosphate synthase, INO1 and overproduce inositol. NuA4 mutants are also display synthetic sickness with a mutant of the lipid remodeling gene SEC14. Here using a combination of genetics and transcriptional profiling, we explore the connections between NuA4, inositol and Sec14. We found that NuA4 mutants exacerbated the inositol auxotrophy of sec14-1ts. Transcriptome studies reveal that loss of the NuA4 subunit EAF1 in sec14-1ts depresses INO1 expression but not all inositol/choline responsive phospholipid genes. This suggests eaf1? cells are defective in coordinating phospholipid homeostasis beyond inositol production. In fact, we discovered that eaf1? cells have significantly lower lipid droplet levels and that inhibition of the fatty acid biosynthesis pathway increased the growth defect of sec14-1ts to a similar extent as untreated sec14-1tseaf1?. Altogether, our work identifies a role for NuA4 as a critical mediator of phospholipid metabolism, potentially as positive regulator of fatty acid biosynthesis.

Description
We developed a R-based script to select internal control genes based solely on read counts and gene sizes. We used this method to pick custom reference genes for the differential expression analysis of three transcriptome sets from transgenic Arabidopsis plants expressing heterologous fungal effector proteins tagged with GFP (using GFP alone as the control). The custom reference genes showed lower covariance and fold change as well as a broader range of expression levels than commonly used reference genes. When analyzed with NormFinder, both typical and custom reference genes were considered suitable internal controls, but the custom selected genes were more stable. geNorm produced a similar result in which most custom selected genes ranked higher (i.e. were more stable) than commonly used reference genes.
