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
Cholesteatoma arises from a tympanic membrane and expands in the middle ear. It erodes the surrounding bone and leads to hearing loss or brain abscess which is lethal complication. Currently, the only effective treatment is the complete surgical removal of cholesteatoma. However, possibility of recurrence is not satisfactory, other clinical treatment is desired. A mechanism of bone erosion in rheumatoid arthritis, which is one of the bone destructive disease, is progressing to be clarified. Receptor activator of NF-?B ligand (RANKL) secreted by synovial fibroblasts, T cells, and B cells lead to differentiation and activation of osteoclast precursor in rheumatoid arthritis. In contrast it has been still unclear why cholesteatoma erodes bone. In the current study we studied that osteoclasts statistically increased in cholesteatoma, and that fibroblasts in the prematrix of cholesteatoma express RANKL. In this study we studied that osteoclasts statistically increased in cholesteatoma, and that fibroblasts in the prematrix of cholesteatoma express RANKL. We investigated upstream of RANKL from RNA sequence results by Ingenuity Pathways Analysis, which is data base of abundance information about molecular biology. Overall design: To generate the transcriptome profiles of the permatrix of cholesteatoma and dermis cut by laser micro dissection from cholesteatoma, three pairs of both sample from the same patients were adapted to RNA sequencing.

Description
Telogen (resting phase) hair follicles are more radioresistant than anagen (growth phase) ones. Irradiation of BALB/c mice in the anagen phase with -rays at 6 Gy induced hair follicle dystrophy, whereas irradiation in the telogen phase induced the arrest of hair follicle elongation without any dystrophy after post-irradiation depilation. In contrast, FGF18 was highly expressed in the telogen hair follicles to maintain the telogen phase and also the quiescence of hair follicle stem cells. Therefore, the inhibition of FGF receptor signaling at telogen induced the dystrophy after post-irradiation depilation. In addition, the administration of recombinant FGF18 suppressed cell proliferation in the hair follicles and enhanced the repair of radiation-induced DNA damage, so FGF18 protected the anagen hair follicles against radiation damage to enhance hair regeneration. Moreover, FGF18 reduced the expression of cyclin B1 and cdc2 in the skin and FGF18 signaling induced G2/M arrest in the keratinocyte cell line HaCaT, although no obvious change of the expression of DNA repair genes was detected by DNA microarray analysis. These findings suggest that FGF18 signaling for the hair cycle resting phase causes radioresistance in telogen hair follicles by arresting the proliferation of hair follicle cells.

Description
Although various mechanisms have been inferred for combinatorial actions of multiple carcinogens, these mechanisms have not been well demonstrated in experimental carcinogenesis models. We evaluated mammary carcinogenesis initiated by combined exposure to various doses of radiation and chemical carcinogens. Female rats at 7 weeks of age were -irradiated (0.22 Gy) and/or exposed to 1-methyl-1-nitrosourea (20 or 40 mg/kg, single intraperitoneal injection) or 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (40 mg/kg/day by gavage for 10 days) and were observed until 50 weeks of age. The incidence of mammary carcinoma increased steadily as a function of radiation dose in the absence of chemicals; mathematical analysis supported an additive increase when radiation was combined with a chemical carcinogen, irrespective of the chemical species and its dose. Hras mutations were characteristic of carcinomas that developed after chemical carcinogen treatments and were overrepresented in carcinomas induced by the combination of radiation and MNU (but not PhIP), indicating an interaction of radiation and MNU at the level of initiation. The expression profiles of seven classifier genes, previously shown to distinguish two classes of rat mammary carcinomas, categorized almost all examined carcinomas that developed after individual or combined treatments with radiation (1 Gy) and chemicals as belonging to a single class; more comprehensive screening using microarrays and a separate test sample set failed to identify differences in gene expression profiles among these carcinomas. These results suggest that a complex, multilevel interaction underlies the combinatorial action of radiation and chemical carcinogens in the experimental model.

Description
In lymphocyte lineages, mucosa-associated lymphoid tissue 1 (MALT1) mediates the nuclear factor-B activation signal that stimulates progression of malignant tumors. However, its expression is inactivated in oral carcinoma patients with worse prognosis. Unveiling genes under the control of MALT1 will provide valuable information for understanding of the mechanism of carcinoma progression.

Description
Gene fusions and chimeric transcripts occur frequently in cancers and in some cases drive the development of the disease. An accurate detection of these events is crucial for cancer research and in a long-term perspective could be applied for personalized therapy. RNA-seq technology has been established as an efficient approach to investigate transcriptomes and search for gene fusions and chimeric transcripts on a genome-wide scale. A number of computational methods for the detection of gene fusions from RNA-seq data have been developed. However, recent studies demonstrate differences between commonly used approaches in terms of specificity and sensitivity. Moreover their ability to detect gene fusions on the isoform level has not been studied carefully so far. Here we propose a novel computational approach called InFusion for fusion gene detection from deep RNA sequencing data. Validation of InFusion on simulated and on several public RNA-seq datasets demonstrated better detection accuracy compared to other tools. We also performed deep RNA sequencing of two well-established prostate cancer cell lines. Using these data we showed that InFusion is capable of discovering alternatively spliced gene fusion isoforms as well as chimeric transcripts that include non-exonic regions. In addition our method can detect anti-sense transcription in the fusions by incorporating strand specificity of the sequencing library. Overall design: Detection of fusion genes and chimeric transcripts from deep RNA-seq data
