Description
The goal of this study was to elucidate the effects of inflammation on bone metabolism. As we found IL-17A is induced immediately after bone injury and Il17a-/- mice showed delayed healing, we analyzed the effects of IL-17A on mesenchymal cells in the repair tissue. Most of the IL-17RA+ cells were PaS cells. We collected these cells and analyzed their response to IL-17A by RNA sequencing. This analysis will provide a mechanistic insight into the mechanism of how IL-17A promote bone formation in the context of bone fracture healing. Overall design: PaS cells were harvested from the injury tissue of wild-type mice and cultured with or without IL-17A or BMP-2. RNAs were harvested at day 7.

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Metastasis to distal organ is a fatal cause of cancer death and liver is one of the most common site of metastasis leading to bad prognosis. Although it has been known that innate immune cells play critical roles in the regulation of liver metastasis, how they control the tumor development is still largely unclear. We found that Dectin-2 (Clec4n), a C-type lectin receptor (CLR), suppresses liver metastasis and such Dectin-2-mediated anti-tumor rejection requires Kupffer cells, liver-residing macrophages, which express Dectin-2 dominantly in liver.

Description
Box C/D-type small nucleolar RNAs (snoRNAs) are functional RNAs responsible for mediating 2-O-ribose methylation of ribosomal RNAs (rRNAs) within the nucleolus. Previously, in relation to a novel chromosomal translocation in a human B-cell lymphoma, we identified U50HG, a non-protein-coding gene that hosted a box C/D-type U50 snoRNA within its intron. To investigate the physiological importance of the U50 snoRNA and its involvement in tumorigenesis, we generated a mouse model deficient in mouse U50 (mU50) snoRNA expression without altering the expression of mouse mU50 host-gene, mU50HG-b. The established mU50 snoRNA-deficient mice showed a significant reduction of mU50 snoRNA expression and the corresponding target rRNA methylation in various organs. Lifelong phenotypic monitoring showed that the mU50-deficient mice looked almost normal without accelerated tumorigenicity; however, a notable difference was the propensity for anomalies in the lymphoid organs.

Description
Neutrophil abscess formation is critical in innate immunity against many pathogens. Here, the mechanism of neutrophil abscess formation was investigated using a mouse model of Staphylococcus aureus cutaneous infection. Gene expression analysis of S. aureus-infected skin revealed that induction of neutrophil recruitment genes was largely dependent upon IL-1beta/IL-1R activation. Unexpectedly, using IL 1beta reporter mice, neutrophils were identified as the primary source of IL-1beta at the site of infection. Furthermore, IL-1beta-producing neutrophils were necessary and sufficient for abscess formation and bacterial clearance. S. aureus-induced IL 1beta production by neutrophils required TLR2, NOD2, FPRs and the ASC/NLRP3 inflammasome. Taken together, IL-1beta and neutrophil abscess formation during an infection are functionally, spatially and temporally linked as a consequence of direct IL-1beta production by neutrophils.

Description
Interleukin-17 (IL-17)-secreting T helper 17 cells (Th17) are a recently identified CD4+ T helper subset that has been implicated in various inflammatory and autoimmune diseases. The issue of whether interleukin-17A (IL-17) contributes to hyperlipidemia-induced aortic endothelial cell activation remained unknown. Here, we reported that IL-17 contributes to hyperlipidemia-induced modulation of vascular cell gene expression during early atherosclerosis in vivo. Our results has shed lights onto the role of IL-17 on EC biology and has provided important insights for future development of novel therapeutics for early intervention of cardiovascular diseases and other inflammatory diseases.

Description
Primary HBE cells were stimulated with IL-22 and IL-17, and gene expression was studied using an Affymetrix platform microarray, in order to investigate which genes may be upregulated or downregulated in response to these cytokines. Of particular interest was the host defense genes such as antimicrobial peptides, which have been shown to be upregulated by IL-22 and IL-17 in skin keratinocytes.

AS1 and AS2 encode MYB related protein and AS2-domain containing protein, respectively and may regulate transcription. These genes are involved in the determination of axes of leaves of Arabidopsis thaliana. To know the gene regulation in the leaf development, expression profile among wild-type, as1 and as2 mutants and AS2 overexpression plants were compaired.

Description
There is much controversy about the role of T-regulatory cells (Treg) in human colon cancer. High densities of tumor-infiltrating Treg can correlate with better or worse clinical outcomes depending on the sutdy. Treg have potent anti-inflammatory functions that have been shown to control cancer progression. However, Treg isolated from patient with colon cancer or in mouse models of polyposis do not have the ability to suppress inflammation and instead promote cancer. Gene expression was preformed to determine differences between Treg isolated from healthy mice and Treg isolated from polyp-ridden mice.
