Mucinous adenocarcinoma (MAC) arising in the oral cavity is extremely rare. We report a case of MAC originating in the palate.<BR>A 70-year-old man presented with an ulcer of the palate visited our hospital. A demarcated tumor arising in the right side of the palate with cervical lymph swelling on the same side were recognized. Histopathological examination revealed a MAC. Partial maxillectomy and radical neck dissection were immediately performed. After surgery, neck metastasis was detected on the contralateral side. Radical neck dissection was therefore performed. After that, recurrence in the right side of the neck and lung metastasis was detected. Bilateral radiotherapy was given to treat recurrence in the neck, and chemotherapy was administered to treat the lung metastasis. The patient died of respiratory insufficiency 2 years 5 months after the first examination.

Wnt5a Gene Plays a Role in Mouse Embryonic Orofacial Development(International Symposium of Maxillofacial & Oral Regenerative Biology in OKAYAMA 2005)

To determine if Wnt5a gene involved in orofacial development, especially secondary palate development, we checked Wnt5a protein and mRNA in wild-type mouse embryos, and also searched Wnt5a knockout mice palates. We found Wnt5a is expressed during orofacial development, especially necessary for normal secondary palate and tongue morphogenesis. Wnt5a deficient mice exhibit cleft palate and abnormal distortion tongue suggests Wnt5a is essential to the palate development. Our data suggested that defection of MEE proliferation in Wnt5a (-/-) secondary palate indicates Wnt5a gene may regulate palate growth.

Effects of immobilized recombinant human bone morphogenetic protein-2/succinylated type I atelocollagen on cellular activity of ST2 cells. 国際誌

Hidetsugu Tsujigiwa, Hitoshi Nagatsuka, Mehmet Gunduz, Andrea Rodriguez, Rosario S Rivera, Racquel Z Legeros, Miho Inoue, Noriyuki Nagai

Journal of biomedical materials research. Part A 75 ( 1 ) 210 - 5 2005年10月

記述言語：英語出版者・発行元：WILEY-LISS

The use of recombinant human bone morphogenetic protein-2 (rhBMP-2) to induce ectopic bone formation requires a carrier. Type I atelocollagen, a biomaterial with a porous structure, excellent operational features, and biocompatibility, is an effective carrier for rhBMP-2. However, the conventionally used lyophilized rhBMP-2/collagen mixture does not necessarily give adequate bone-induction effect. In the present study, we examined the effect of immobilizing rhBMP-2 to type I atelocollagen on the cellular activity of ST2 cells. The following results were obtained: (1) rhBMP-2 was effectively immobilized to succinylated type I atelocollagen, indicating the usefulness of succinylated type I atelocollagen in immobilization; (2) studies of alkaline phosphatase activity confirmed the effectiveness of rhBMP-2 immobilized on succinylated atelocollagen in augmenting cellular activity.

Study of Amelogenin Gene Expression in Ameloblastoma

Hidetsugu Tsujigiwa, Hitoshi Nagatsuka, Mehmet Gunduz, Masao Yamada, Noriyuki Nagai, Shin Hong-In, Satoshi Ichihara

Journal of Hard Tissue Biology 14 ( 2 ) 192 - 193 2005年1月

記述言語：英語

Although it has been known that amelogenin gene is expressed in ameloblastoma, the precise expression pattem of X and Y amelogenin genes (AMGX, AMGY) in this tumor has not yet identified. In this study, we analyzed amelogenin gene expression in 19 samples (9 male, 10 female) of oral ameloblastomas by RT-PCR and detect the chromosomal origin of amelogenin mRNA by restriction enzyme digestion of the RT-PCR product. All tumor samples expressed amelogenin mRNA. We could detect increased level of AMGY expression in all male samples, higher than that of AMEX. It is an interesting finding as in normal male tooth development, the expression of AMGY is very much lower than that of AMGX. We postulate that epigenetic change of sex chromosomes may have some correlations with tumorigenesis of ameloblastoma. We also discuss the other possible mechanisms and points for future studies on this the change in expression pattern. © 2005, THE SOCIETY FOR HARD TISSUE REGENERATIVE BIOLOGY. All rights reserved.

We studied the expression of Notch1, Math1, Jagged2 and Hes5 in the regenerated olfactory epithelium (OE) of adult mice. The OE was first destroyed by intranasal zinc sulfate irrigation and, after 7days, some regenerated areas were observed by in situ hybridization (ISH). In mice treated with zinc sulfate, Notch1 expression was sparsely observed in the regenerated OE and the number of Notch1-positive cells appeared to be lower than that in the OE of control cases. Math1 and Jagged2 expression was observed in the regenerated OE. These expression patterns appear to be the same as those in control cases. No Hes5 was observed in either the normal or regenerated OE. We concluded that Notch1 down-regulation in the damaged OE may play an important role in OE regeneration.
