Description
The fetal ovarian grafts under the kidney capsule of adult male mice undergo a partial sex-reversal showing ectopic SOX9-positive Sertoli cell-like cells around 15-20 days post-transplantation. However, the molecular bases of such masculinization of fetal ovaries in the paternal environment were unclear.

Description
Phosphatidylcholine transfer protein (PC-TP, a.k.a StarD2) is abundantly expressed in liver and is regulated by PPAR. When fed the synthetic PPAR ligand fenofibrate, Pctp-/- mice exhibited altered lipid and glucose homeostasis. Microarray profiling of liver from fenofibrate fed wild type and Pctp-/- mice revealed differential expression of a broad array of metabolic genes, as well as their regulatory transcription factors. Because its expression controlled the transcriptional activities of both PPAR and HNF4 in cell culture, the broader impact of PC-TP on nutrient metabolism is most likely secondary to its role in fatty acid metabolism.

Description
Spermatogonial stem cells (SSCs) provide foundation for spermatogenesis by undergoing continuous self-renewal division. Previous studies have reported conflicting results on the role of the pituitary gland activity in SSC self-renewal. In this study, we analyzed the role of hormonal regulation of SSCs using Lhcgr (luteinizing hormone/choriogonadotropin receptor) knockout mice. Analysis of gene expression profiles showed that testes of Lhcgr-deficient mice exhibit significantly enhanced Wnt5a expression in Sertoli cells.

Description
Resiquimod is a nucleoside analog belonging to the imidazoquinoline family of compounds which is known to signal through Toll-like receptor 7. Resiquimod treatment has been demonstrated to inhibit the development of allergen induced asthma in experimental models. Despite this demonstrated effectiveness, little is known about the molecular events responsible for this effect. The aim of the present study was to elucidate the molecular processes which were altered following resiquimod treatment and antigen challenge in a mouse model of allergic asthma. Employing microarray analysis, we have characterized the asthmatic transcriptome of the murine lung and determined that it includes genes involved in: the control of cell cycle progression, airway remodelling, the complement and coagulation cascades, and chemokine signalling. We have demonstrated that systemic resiquimod administration resulted in the recruitment of NK cells to the lungs of the mice, although no causal relationship between NK cell recruitment and treatment efficacy was found. Furthermore, results of our studies demonstrated that resiquimod treatment resulted in the normalization of the expression of genes involved with airway remodelling and chemokine signalling, and in the modulation of the expression of genes including cytokines and chemokines, adhesion molecules, and B-cell related genes, involved in several aspects of immune function and antigen presentation. Overall, our findings identified several genes, important in the development of asthma pathology, that were normalized following resiquimod treatment thus improving our understanding of the molecular consequences of resiquimod treatment in the lung milieu.

Description
Ewings sarcoma is highly malignant bone tumor that involves childhood and adolescent, and its nature has not been well understood. To clarify its cellular origin and the mechanisms of tumorigenesis, we used ex vivo approach to create a murine model for Ewings sarcoma. The osteochondrogenic progenitors derived from the embryonic superficial zone (eSZ, designated as FZ in the data set) of murine long bones at late gestation were purified by microdissection, introduced with EWS-FLI1 or EWS-ERG retroviruses and transplanted into nude mice. Ewings sarcoma-like small round cell sarcoma developed at 100% penetrance, whereas tumor induction was less effective when growth place (GP)-derived cells were used. The different response of gene expression to EWS-FLI1 between eSZ and GP cells suggests importance of the specific cellular context for EWS-FLI1 to induce Ewings sarcoma. The Wnt/-catenin pathway was involved in close relationship to the cellular context, with Dkk2 and Wipf1 as important downstream modulators. Furthermore, gene expression profiling revealed similarity between our models and human Ewings sarcoma. These results indicate that Ewings sarcoma originates from the embryonic osteochondrogenic progenitor.

Description
The host antitumor immunity changes drastically during carcinogenesis. Intraductal papillary-mucinous neoplasm (IPMN) of the pancreas is a precursor lesion of pancreatic cancer and progresses according to adenoma-carcinoma sequence. We found that the host antitumor immune reaction changes from an immune response to immune tolerance between intraductal papillary-mucinous adenoma (IPMA) and intraductal papillary-mucinous carcinoma (IPMC).
Publication Title
CXCL17 and ICAM2 are associated with a potential anti-tumor immune response in early intraepithelial stages of human pancreatic carcinogenesis.
