MicroRNAs induced during adipogenesis that accelerate fat cell development are downregulated in obesity.

<h4>Objective</h4>We investigated the regulation and involvement of microRNAs (miRNAs) in fat cell development and obesity.<h4>Research design and methods</h4>Using miRNA microarrays, we profiled the expression of >370 miRNAs during adipogenesis of preadipocyte 3T3-L1 cells and adipocytes from leptin deficient ob/ob and diet-induced obese mice. Changes in key miRNAs were validated by RT-PCR. We further assessed the contribution of the chronic inflammatory environment in obese adipose tissue to t ...[more]

MicroRNA profiling of liver from vitellogenic and non-vitellogenic zebrafish females

Project description:Liver samples were collected from zebrafish females (3 months old). Vitellogenic females were maintained under conditions of 14 h light: 10 h dark. Non-vitellogenic females were obtained by exposing females to 6 h light/18 h dark regime.

Transcription profiling of human dendritic cells treated with lipopolysaccharides and R848

Project description:Toll-like receptor (TLR) signalling activation by pathogens is critical to the induction of immune responses, and demands tight regulation. Chemokine ligand 2 (CCL2) secretion triggered by TLR4 or TLR8 engagement is strongly inhibited upon simultaneous activation of both TLRs in human monocyte-derived dendritic cells (MD-DC). Impaired CCL2 secretion occurs concomitantly to IL-12 up-regulation, being part of a complex regulatory circuit ensuring optimal Th type 1 polarization. Interestingly, triggering selected TLRs or their combinations differently affects nuclear factor-kB p65 activation and microRNA expression. To investigate in details such different modulation we performed a microarray profiling of MD-DCs stimulated by different TLRs agonist or their combination in three different donors. We found that CCL2 supplies an important immunomodulatory role to DCs, and may contribute to dictate the cytokine profile in Th type 1 responses induced by DCs.

miRNA profiling of mouse primary peritoneal macrophages infected with vesicular stomatitis virus (VSV)

Project description:To investigate whether and what miRNAs expression might be regulated by VSV (vesicular stomatitis virus?) challenge, we analyzed the miRNA expression profile of mouse primary peritoneal macrophages infected with VSV by using an array-based miRNA profiling. After the infection of VSV at MOI 10 for 48 h, the array revealed that many miRNAs were up-regulated in macrophages?
