The protein expression profile of clear cell type mucoepidermoid carcinoma (MEC) is not well known.
We examined a case of clear cell type MEC by immunohistochemical (IHC) array using 59 antibodies against oncoproteins, proliferation-related proteins, apoptosis-related proteins, growth factor-related proteins, angiogenesis-related proteins, and matrix proteins.
MEC tumor cells showed 40 to 60% more expression of BCL-2 and cyclin-dependent kinase 4 than normal gingival tissue, and 20-40% more expression of BCL-2-associated agonist of cell death, deleted in malignant brain tumors 1, E-cadherin, eIF5A, hypoxia-inducible factor, vimentin, and Wnt-1. Expression of other proteins, including p53, epidermal growth factor receptor, proliferating cell nuclear antigen, survivin, carcinoembryonic antigen, beta-catenin, poly-ADP ribose-polymerase, etc. were relatively weak in MEC tumor cells.
The IHC array for our MEC contained strong oncogenic signals involving Wnt-1/adenomatous polyposis coli, tumor necrosis factor a/signal transducer and activator of transcription 3/BCL-2, and pAKT pathways, signals that could result in the prolonged survival of clear tumor cells.

AbstractAbstract PDF
In order to obtain novel genes for craniofacial development of human, molecular cloning and sequencing were performed and followed by in situ hybridization in tissue sections. Subtracted cDNA library of craniofacial tissue from 8 weeks old human embryo was made by the subtraction with cDNA of RHEK cells. A total of 231 clones were obtained and their partial sequence data disclosed that 214 clones were nonredundant in Genebank search. We have done in situ hybridization screening on the craniofacial sections of a 10 weeks old human fetus, and found significant positive reaction in 30 clones. Depending on the cell type of similar developmental origin, the positive reactions could be divided into four groups: first group showed an intense positive reaction in neural tube, ganglion, and a part of peripheral nerve tissue, second group relatively diffuse positive reaction in neural tube, cartilage, epithelium, and muscle, third group localized positive reaction in nerve, and muscle, and fourth group positive reaction in almost all kinds of cells of craniofacial tissues. Although every clone showed different expression patterns in the craniofacial development, some of them showed intense mRNA expressions in the characteristic cell type. Because this study also aimed to test a screening methods to find out novel genes related to craniofacial development by the subtracted cDNA library and in situ hybridization, the intense positive reaction of a certain clone by in situ hybridization may indicate its role in the developmental processes. We presumed that 30 clones selected in this study are possibly important new genes for the development of human craniofacial structure.

AbstractAbstract PDF
This study was designed to answer the question; (1) How does the DNA ploidy pattern change in hepatocarcinogenesis? (2) How does the nuclear morphology change in hepatocarcinogenesis? Diethylnitrosamine(DEN) (16.5 mg per kg) was subcutaneously injected to female Sprague-Dawley rats(150~200g) by weekly interval for 30 weeks. DNA ploidy and parameters of nuclear morphology were measured by image analyser(IBAS 200, Kontron, FRG). The DNA ploidy pattern was divided into three basic patterns(diploid, polyploid, and aneuploid modes). In 8 cases of saline-injected control rats, the DNA histograms showed all polyploid pattern. Inhepatocyte nodules(hyperplastic nodules), DNA diploidy was the most frequent pattern, being followed by polyploid and aneuploid DNA patterns, contrast to hepatocelular carcinomas in which polyploid DNA pattern was most frequently noted being followed by diploid and aneuploid DNA pattern. Although the nuclei of hepatocytes in hepatocyte nodules and hepatocellular carcinomas were larger and more pleomorphic than those of normal hepatocytes, they were as same as those of normal hepatocytes in regard to nuclear hyperchromasia. DNA content, which was increased in hepatocarcinogenesis, was significantly related to the nuclear area.
