Establishment and biological characteristics of a new oral squmaous carcinoma cell line, MISK 81-5, had been published in Japanese Journal of Cancer Research. MISK 81-5 cells showed an aneuploid chromosomal, and released cathepsin D into culture media, which protease is supposed to correlate with invasive potencies of carcinoma cells. This cell line alos produced a high level of granulocyte colony-stimulating factor demonstrated by stem cell assay and ELISA.An experimental study on the alteration of the invasive potency has been performed by transfecting a human cathepsin D cDNA into the cell line. Preparations of antibodies against unknown antigens correlated with transformation and adhesion molecules on the cell surface has been also investigating.Proliferative activities of the dysplasia and carcinoma in situ in the uterine cervix, and oral mucosa were investigated by means of PCNA immunostaining and AgNORs staining. These studies disclosed the close correlation between the proliferative activity and the severity of the dysplasia in uterine cervix and oral mucosa, main histological components related to severe epithelial dysplasia of the oral micosa were clarified. The results of these investigations have been published in Human Pathology. Immunohistochemical examinations on the localization of p53, as a tumor suppressor gene in oral precancerous lesion, as well as detections of its mRNA and point mutations by using PCR and in situ hybridization methods, are proceeding.Immunohistochemical localizations of cathepsins D and E in primary gastric cancer were investigated. The results that these proteases were strongly expressed in carcinoma cells at the advancing mergin suggesting a closely correlation with the local invasion of carcinoma cells and following metastsis to the lymph nodes. This sytudy has been submitted to a journal.

一种新的口腔鳞癌细胞系MISK 81-5的建立及其生物学特性已发表在日本癌症研究杂志上。MISK 81-5细胞显示非整倍体染色体，并向培养基中释放组织蛋白酶D，该蛋白酶被认为与癌细胞的侵袭能力相关。用干细胞分析和ELISA方法证明该细胞系能产生高水平的粒细胞集落刺激因子，并通过转染人组织蛋白酶D cDNA对该细胞系侵袭力的影响进行了实验研究。用PCNA和AgNORs免疫组化染色方法研究了宫颈、口腔粘膜异型增生和原位癌的增殖活性。这些研究揭示了宫颈和口腔粘膜上皮细胞的增殖活性与其异型增生的严重程度密切相关，阐明了与口腔粘膜上皮重度异型增生相关的主要组织学成分。这些研究结果已发表在《人类病理学》上。应用免疫组织化学方法对口腔癌前病变组织中抑癌基因p53的定位、PCR和原位杂交方法检测p53的mRNA和点突变，并对原发性胃癌组织中组织蛋白酶D和E的免疫组织化学定位进行了研究。结果表明，这些蛋白酶在癌细胞中的融合区有强表达，提示它们与癌细胞的局部浸润和淋巴结转移密切相关。这篇论文已经提交给一家杂志。
