Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Fusion of branchial arch derivatives is an essential event in the development of craniofacial architecture. A unique feature of the mandibular arch development is medial/lateral compartmentalization for the molecular networks. Those networks give rise to multiple region-specific organs, namely teeth, a tongue, salivary glands, and the supporting matrices such as bones and cartilages.

Description
Objectives: Sex hormone receptors are reported to be present in human dental pulp (HDP) cells. The purpose of this study was to examine the biological significance of estrogen and androgen receptors (ER and AR, respectively) in HDP cells. Design: We isolated HDP cells expressing ER- and AR-mRNAs and investigated the expression status of the receptors and the response to sex hormones in the cells. Results: HDP cells expressing ER- and/or AR-mRNAs had the ability to form alizarin red S-positive nodules in which calcium and phosphorus were deposited in vitro and to differentiate into odontoblasts-like cells and dentin-like tissue in vivo. Individual clones isolated from HDP cells exhibited a different expression pattern of mRNA for ER and AR. Some clones expressed ER- and/or ER-mRNAs and the others coexpressed ER- and AR-mRNAs. Using the Ingenuity software, we found that 17-estradiol (E2) and dihydrotestosterone (DHT) could act directly on HDP cells through ER- or androgen signaling-mediated mechanisms. E2 or DHT stimulated the mRNA expression for genes related to odontogenesis of dentin-containing teeth and odontoblast differentiation, suggesting that ER and AR in HDP cells may be involved in dentinogenesis. Conclusions: Our findings provide new insights into the biological significance of sex hormone receptors in HDP cells.

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
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
Introduction: The majority of pulmonary carcinoid (PC) tumors can be cured by surgical resection alone, but a significant proportion of patients experience recurrences. PC is insensitive to conventional chemotherapy, and it would be necessary to reveal the molecular mechanisms of metastasis and develop targeted therapeutics.

Description
In order to ascertain the potential for histone deacetylase (HDAC) inhibitor-based treatment in non-small cell lung cancer (NSCLC), we analyzed the anti-tumour effects of Trichostatin A (TSA) and suberoylanilide hydroxamic acid (vorinostat) in a panel of 16 NSCLC cell lines via MTT assay. TSA and vorinostat both displayed strong anti-tumor activities in a proportion of NSCLC cell lines, and suggesting the need for the use of predictive markers to select patients receiving this treatment. There was a strong correlation between the responsiveness to TSA and vorinostat (P < 0.0001).

Description
The tumorigenesis capacity of MLL-AF4 alone is insufficient for causing leukemia. Based on the finding that an Flt3 gene mutation in the tyrosine kinase domain (TKD) was observed in approximately 15% of MLL leukemia, we investigated synergistic leukemogenesis effects of the two genes in vitro. In a mouse IL3-dependent cell line, 32Dc, the expression of MLL-AF4 and Flt3 TKD was induced using a lentiviral vector. We performed gene expression profiling in the MLL-AF4 and the Flt3 TKD+MLL-AF4 expressing 32Dc cells. The enhancement of Hox genes expression was not identified. However, instead, the expression of S100A6, which was involved in the control of cell proliferation, was synergistically enhanced in the presence of both MLL-AF4 and Flt3 TKD genes.
