    • A DNA encoding a novel steroid hormone receptor-like protein was obtained from a human fetal lung cDNA library, and its structure was determined. Further, the protein encoded by the gene was isolated, identified, and designated as an ECDN protein. Furthermore, a protein encoded by a DNA lacking a part of the above gene was isolated, identified, and designated as an ECDN paucimolecular protein.It was proven that the ECDN paucimolecular protein was expressed in various cancer cells. Therefore, it is expected that it becomes possible to diagnose and treat cancers by analyzing the expression of the ECDN protein and the ECDN paucimolecular protein in a subject tissue. Furthermore, attained to develop novel pharmaceuticals can be developed by finding natural and synthetic compounds capable of binding specifically to the ECDN protein and the ECDN paucimolecular protein.

    • A gene is provided which is present in the deletion region of a chromosome common in lung cancer, hepatocellular carcinoma and colorectal cancer and encodes a novel protein, a protein encoded by the gene (PRLTS protein), and a method of discriminating tumor cells. With respect to the human chromosome 8, a detailed gene map was prepared, the chromosome of each of lung cancer, hepatocellular carcinoma and colorectal cancer tissues was analyzed, and a gene encoding a novel protein was cloned to thereby determine the structure thereof. A gene analysis was conducted with the use of a DNA probe derived from the above gene, and consequently mutations in the gene were confirmed in the lung cancer, hepatocellular carcinoma and colorectal cancer tissues.
    • 提供存在于肺癌,肝细胞癌和结肠直肠癌中常见的染色体的缺失区域中的基因,并编码新的蛋白质,由该基因编码的蛋白质(PRLTS蛋白质)和鉴别肿瘤细胞的方法。 对于人染色体8,制备了详细的基因图,分析了肺癌,肝细胞癌和结肠直肠癌组织的染色体,克隆了编码新蛋白的基因,从而确定了其结构。 使用源自上述基因的DNA探针进行基因分析,因此在肺癌,肝细胞癌和结肠直肠癌组织中证实了基因突变。

    • A detailed genetic map on human chromosome 11 was prepared. Then, a commonly deleted region on the chromosome in the tumor tissues of patients with multiple endocrine neoplasia type 1 was identified. Further, by linkage analysis of a family line with this disease, a genetic cause for this disease was localized. A gene present in the region common to these observations was cloned and the structure of this gene was determined. Because a protein coded by this DNA is homologous with those of transcriptional factors, it is expected that the above-mentioned gene may be a novel tumor suppressor gene. Further, it is also expected that the above-mentioned gene and a protein coded for thereby may be useful in preparation of a remedy for cancer and a diagnostic drug for cancer.
    • 准备了人类染色体11上的详细遗传图谱。 然后,鉴定了多发性内分泌瘤1型患者肿瘤组织染色体上普遍缺失的一个区域。 此外,通过家族系与这种疾病的联系分析,本病的遗传原因是本病。 克隆了与这些观察结果共同的区域中存在的基因,并测定了该基因的结构。 由于由该DNA编码的蛋白质与转录因子的蛋白质同源,所以预期上述基因可能是新的肿瘤抑制基因。 此外,还预期上述基因和由此编码的蛋白质可用于制备癌症治疗剂和癌症诊断药物。
