Description
PBRM1 is a component of the PBAF chromatin remodelling complex and has been observed to be deregulated in a significant proportion of patients with clear-cell Renal Cell Carcinoma (ccRCC). This study employs RNA-Seq to identify differentially expressed genes in cellular models of ccRCC by expressing PBRM1 in PBRM1-deficient Caki2 cells. Overall design: Using lentiviral mediated mechanism, stable Caki-2 cell line expressing PBRM1 was developed (Caki2-PBRM1). Empty vector inserted in Caki2 cells served as control (Caki2-Ø)

Description
The adult zebrafish is capable of regenerating heart muscle, resolving collagen tissue and fully restoring heart function throughout its life. The goal of this study was to investigate how the highly upregulated, epicardium-enriched microRNA let-7i functions in wound closure and cardiomyocyte proliferation. We found that depletion of let-7 in adult zebrafish using locked-nucleic acid (LNA) antisense oligonucleotides results in defective heart regeneration. We assayed gene expression at 7 days post ventricular resection in LNA-scrambled and LNA-anti-let-7 treated adult zebrafish to determine the role of let-7 during heart regeneration. Overall design: mRNA gene expression profiling at 7 days post ventricular resection in LNA-scrambled and LNA-anti-let-7 treated zebrafish.

Description
Adult zebrafish are capable of regenerating cardiac tissue following ventricular resection within 30 days. We profiled both small RNA and mRNA expression in uninjured (0dpa), 1, 3, 7, 14, 21 and 30 days post amputation to study biological processes orchestrate each stage of regeneration. Overall design: Small and mRNA gene expression profiling during 0, 1, 3, 7, 14, 21 and 30 days post ventricular resection.

Description
Dosage compensation restores a balanced network of gene expression between autosomes and sex chromosomes in males (XY) and females (XX). In mammals, this is achieved by doubling the expression of X-linked genes in both sexes, together with X inactivation in females. X up-regulation may be controlled by DNA sequence based and/or epigenetic mechanisms that double the X output potentially in response to an autosomal counting factor. Human triploids with either one or two active X chromosomes (Xa) provide a mean to test X chromosome expression in the presence of three sets of autosomes, which will help understand the underlying mechanisms of X up-regulation.

Description
The molecular mechanisms of Trypanosoma cruzi induced cardiac fibrosis remains to be elucidated. Primary human cardiomyoctes (PHCM) exposed to invasive T. cruzi trypomastigotes were used for transcriptome profiling and downstream bioinformatic analysis to determine fibrotic-associated genes regulated early during infection process (0 to 120 minutes). The identification of early molecular host responses to T. cruzi infection can be exploited to delineate important molecular signatures that can be used for the classification of Chagasic patients at risk of developing heart disease. Our results show distinct gene network architecture with multiple gene networks modulated by the parasite with an incline towards progression to a fibrogenic phenotype. Early during infection, T. cruzi significantly upregulated transcription factors including activator protein 1 (AP1) transcription factor network components (including FOSB, FOS and JUNB), early growth response proteins 1 and 3 (EGR1, EGR3), and cytokines/chemokines (IL5, IL6, IL13, CCL11), which have all been implicated in the onset of fibrosis. The changes in our selected genes of interest did not all start at the same time point. The transcriptome microarray data, validated by quantitative Real-Time PCR, was also confirmed by immunoblotting and customized Enzyme Linked Immunosorbent Assays (ELISA) array showing significant increases in the protein expression levels of fibrogenic EGR1, SNAI1 and IL 6. Furthermore, phosphorylated SMAD2/3 which induces a fibrogenic phenotype is also upregulated accompanied by an increased nuclear translocation of JunB. Pathway analysis of the validated genes and phospho-proteins regulated by the parasite provides the very early fibrotic interactome operating when T. cruzi comes in contact with PHCM. The interactome architecture shows that the parasite induces both TGF- dependent and independent fibrotic pathways, providing an early molecular foundation for Chagasic cardiomyopathy. Examining the very early molecular events of T. cruzi cellular infection may provide disease biomarkers which will aid clinicians in patient assessment and identification of patient subpopulation at risk of developing Chagasic cardiomyopathy.

Description
The cytokines GM-CSF and IL-5 are thought to possess largely divergent functions despite a shared dependence on the common beta (βC) chain to initiate signaling. Although IL-5 is part of the core type 2 cytokine signature and is required for protection against some helminths, it is dispensable for immunity to others, such as Heligmosomoides polygyrus bakeri (H. polygyrus). Whether this is due to compensatory mechanisms is unclear. The transcription factor Bhlhe40 has been shown to control GM-CSF production and is proposed to be a novel regulator of T helper type 2 cells.
