Description
Background: Elevated plasma cholesterol promotes the formation of atherosclerotic lesions in which monocyte-derived lipid-laden macrophages are frequently found. To analyze, if circulating monocytes already show increased lipid content and differences in lipoprotein metabolism, we compared monocytes from patients with Familial Hypercholesterolemia (FH) with those from healthy individuals.
Publication Title
Monocytes of patients with familial hypercholesterolemia show alterations in cholesterol metabolism.

Description
To compare up-regulation of genes following CpG activation, we performed microarray analysis of activated macrophages from B6 and F1(B6xMOLF) mouse strains. Cells were activated for 0, 2 and 4 hrs with 200nM of type B CpG. Levels of mRNA for many genes differened dramatically between the strains

Description
In vertebrates, the heart has two main layers of cardiac muscle, a peripheral compact layer and an internal trabecular layer. Little is known on the differerences in gene expression between both layers. In zebrafish the outer layer is named cortical layer and the internal also trabecular layer. Here we used a double transgenic line labelling with GFP tbx5-positive cells and cardiomyoctes with nuclear DsRed (nucDsRed) to distinguish cortical from trabecular myocardium. Then, we compared the transcriptome of trabecular and cortical myocardium in the adult zebrafish. We describe that Tbx5a is a good marker of trabecular myocardium. Overall design: Four paired biological replicates consisting on Tbx5-positive and Tbx5-negative adult zebrafish ventricular cardiomyocytes were analysed by RNA-seq to compare their transcriptomic profiles.

Tbx5a lineage tracing shows cardiomyocyte plasticity during zebrafish heart regeneration.

Description
The tumor microenvironment plays a critical role in cancer progression, but the precise mechanisms by which stromal cells influence the tumor epithelium are poorly understood. The signaling adapter p62 has been implicated as a positive regulator of epithelial tumorigenesis; however, its role in the stroma is unknown. We show here that p62 levels are reduced in the stroma of several tumors. Also, orthotopic and organotypic studies demonstrate that the loss of p62 in the tumor microenvironment or stromal fibroblasts resulted in increased tumorigenesis of epithelial prostate cancer cells. The mechanism involves the regulation of cellular redox through an mTORC1/c-Myc pathway of stromal glucose and amino acid metabolism. Inhibition of the pathway by p62 deficiency results in increased stromal IL-6 production, which is required for tumor promotion in the epithelial compartment. Thus, p62 is an anti-inflammatory tumor suppressor that acts through modulation of metabolism in the tumor stroma.

Metabolic reprogramming of stromal fibroblasts through p62-mTORC1 signaling promotes inflammation and tumorigenesis.

Description
Dengue virus (DENV) infection is one of the most serious public health problems worldwide. A recent dengue outbreak in Paraguay (2007-2009) presented unusual manifestations such as hepatitis, encephalitis, pulmonary as well as cardiac disorders associated with 50% of deaths caused by dengue in the country. Despite the knowledge on inflammatory responses observed during the course of disease, the role of innate immune cells in the control of virus replication influencing clinical outcome is poorly defined. Using two clinical isolates of the virus, a non-fatal case of classical DF (DENV3/290) and a fatal case of DF with visceral complications (DENV3/5532), we sought to determine the profile of dengue infection in human dendritic cell, a major innate immune cell population. Compared to classical DENV3/290, the strain DENV3/5532 displayed higher replicative ability in mdDCs. In addition, DENV3/5532 was found to induce elevated production of pro-inflammatory cytokines associated with higher rates of programmed cell death. The observed phenotype was due to viral replication in mdDCs and TNF appeared to display a protective effect on virus-induced mdDCs apoptosis. These results suggest that the fatal case DENV3/5532 isolate modulates dendritic cell survival as well as inflammatory mediators synthesis.

Dengue virus type 3 isolated from a fatal case with visceral complications induces enhanced proinflammatory responses and apoptosis of human dendritic cells.

Description
Analysis of mobilized peripheral blood CD34+ cells from a healthy volunteer under erythroid differentiation conditions with and without stimulation to the BMP or Wnt signaling pathways. For erythroid differentiation, expanded CD34+ cells were placed in Stemspan SFEM medium supplemented with 2% pen/strep, 20ng/ml SCF, 1U/ml Epo, 5ng/ml IL3, 2uM dexamethasone, and 1uM beta-estradiol. Arrays were performed 2 hours after addition of cytokines. For signaling pathway stimulation, cells were exposed to 0.5uM BIO (a GSK3 inhibitor) for Wnt pathway activation, 25ng/ml rhBMP4 for BMP pathway activation, or vehicle control for 2 hours. Three biological replicates were performed per treatment group.

Description
drl expression initiates during gastrulation and condenses as a band of cells at the prospective lateral embryo margin. In late epiboly, drl:EGFP is detectable as a band of scattered EGFP-fluorescent cells; after gastrulation, drl:EGFP-positive cells coalesce at the embryo margin that then in somitogenesis break down into the anterior and posterior lateral plate with subsequent cell migrations that form the posterior vascular/hematopoietic stripes and the anterior cardiovascular and myeloid precursors.
