Description
In order to identify genes dysregulated by the aberrant transcriptional activity of RUNX1-RUNX1T1, we used microarrays to determine the effect of this mutation on gene expression during myeloid and erythroid development of normal human progenitor cells.
Publication Title

Description
T-cell acute lymphoblastic leukemia (T-ALL) and lymphoma (T-LBL) share common morphologic and immunophenotypic features and are treated with similar therapeutic approaches. Nonetheless, they show distinct clinical presentations suggesting that they may represent two different biological entities. In order to investigate T-LBL and T-ALL biological characteristics we used transcriptional profiling approache. Genome-wide gene expression profiling, performed on 20 T-LBL and 10 T-ALL diagnostic specimens, showed that the two malignancies shared a large fraction of their transcriptional profile while a subset of genes appeared to be differentially expressed in T-LBL versus T-ALL. This gene signature included genes involved in chemotactic responses and angiogenesis which might play a role in the different tumor cell localization suggesting that T-LBL and T-ALL could be two distinct diseases with unique transcriptional characteristics.

Description
Bronchial asthma is associated with type 2 immune responses induced by components of adaptive as well as innate immunity. Although innate cytokines such as IL-25 have been shown to play key roles in development of airway hyperreactivity (AHR), little is known of innate molecules that regulate IL-25-mediated airway inflammation. We found that blockade of repulsive guidance molecule b (RGMb) in an experimental murine model of asthma blocked the development of AHR, a cardinal feature of asthma, and that RGMb is expressed on F4/80+CD11b+CD11cneg macrophages (RGMb+ macrophages), which accumulated in the lungs of OVA-sensitized and challenged mice, but not in nave mice. Moreover, we found that a large fraction of the RGMb+ macrophages expressed the IL-25 receptor IL-17RB and produced IL-13. IL-25 was critical for the development of AHR in our model, since mice deficient in IL-17RB did not develop AHR. Finally, treatment with anti-RGMb mAb during the challenge phase of the protocol after allergen sensitization effectively prevented the development of AHR and airway inflammation, suggesting for the first time that RGMb+ cells, including RGMb+ macrophages, play critical roles in allergen-induced asthma.

Description
It is currently debated as to whether liver macrophage (LM) activation from an anti-inflammatory to pro-inflammatory phenotype contributes to obesity-induced metabolic diseases. Here we report that LMs do not undergo a pro-inflammatory phenotype switch in obesity-induced insulin resistance in mice and humans. Remarkably, immune response related genes remained also unchanged in fly immune cells (haemocytes) upon high fat feeding. However, unbiased transcriptomic analyses revealed that LMs produce non-inflammatory factors, such as insulin like growth factor binding protein 7 (Igfbp7), that directly regulate liver metabolism. Using a unique method to manipulate gene expression only in LMs in vivo, we discovered that IGFBP7 specifically produced by LMs binds the insulin receptor and induces lipogenesis and gluconeogenesis, two major pathways increased in metabolic diseases. This study shows that macrophages could contribute to insulin resistance independently of their inflammatory status and that targeting non-inflammatory factors produced by macrophages might represent a better strategy than anti-inflammatory drugs to tackle metabolic diseases.

Description
Angelica polysaccharide (APS) is one of the major active components isolated from Angelica sinensis. Evidences suggested APS may have therapeutic potential for psoriasis. HaCaT cell line was commonly used as an in vitro model to study psoriasis. In the present study, RNA-sequencing (RNA-seq) was performed to investigate the underlying mechanism of APS. Different concentrations of APS (0mg/mL, 50 mg/L, 100 mg/L and 200mg/L) were incubated with HaCaT cells for 36 h and transcriptome sequenced. Comparison of the gene expression profiles between the CK group (i.e., Control group) and ASP groups revealed dramatic differences. All the differentially expressed genes (DEGs) were then classified into 20 expression profiles by trend analysis. Significant enriched trend clusters were then analyzed. Interestingly, cell proliferation related gene ontology (GO) terms were mostly dispersed in the profile 2 and 17. Based on our functional annotation results and reported literature, authors suspected that SERPINE1, SMAD6 and CTGF, together with TGF-ß, may closely relevant to the anti-proliferation effect of APS.
