    • Isolated peptides derived from SEQ ID NO: 42 and fragments thereof that bind to an HLA antigen and induce cytotoxic T lymphocytes (CTL) and thus are suitable for use in the context of cancer immunotherapy, more particularly cancer vaccines, are described herein. The inventive peptides encompass both the afore-mentioned amino acid sequences and modified versions thereof, in which one, two, or several amino acids are substituted, deleted, inserted or added, provided such modified versions retain the requisite HLA binding and/or CTL inducibility of the original sequences. Further provided are nucleic acids encoding any of the aforementioned peptides as well as pharmaceutical agents, substances and/or compositions that include or incorporate any of the aforementioned peptides or nucleic acids. The peptides, nucleic acids, pharmaceutical agents, substances and compositions of this invention find particular utility in the treatment of cancers and tumors, including, for example, bladder cancer, breast cancer, cervical cancer, cholangiocellular carcinoma, CML, colorectal cancer, esophageal cancer, NSCLC, lymphoma, pancreatic cancer, prostate cancer, renal carcinoma and SCLC.
    • 衍生自SEQ ID NO:42的分离的肽及其与HLA抗原结合并诱导细胞毒性T淋巴细胞(CTL)的片段,因此适用于癌症免疫治疗,特别是癌症疫苗的上下文中。 本发明的肽包括上述氨基酸序列及其修饰形式,其中一个,两个或几个氨基酸被取代,缺失,插入或添加,只要这些修饰版本保留所需的HLA结合和/或CTL诱导性 的原始序列。 还提供了编码任何前述肽的核酸以及包括或掺入任何前述肽或核酸的药物,物质和/或组合物。 本发明的肽,核酸,药物,物质和组合物在治疗癌症和肿瘤方面特别有用,包​​括例如膀胱癌,乳腺癌,子宫颈癌,胆管细胞癌,CML,结肠直肠癌,食管癌 ,NSCLC,淋巴瘤,胰腺癌,前列腺癌,肾癌和SCLC。

    • In order to identify the molecules involved in esophageal carcinogenesis and those to be useful for diagnostic markers as well as targets for new drugs and immunotherapy, a cDNA microarray representing 32,256 genes was constructed to analyze the expression profiles of 19 esophageal squamous-cell carcinomas (ESCCS) purified by laser-capture microdissection. A detailed genome-wide database for sets of genes that are significantly up- or down-regulated in esophageal cancer is disclosed herein. These genes find use in the development of therapeutic drugs or immunotherapy as well as tumor markers. Additionally, genes associated with lymph-node metastasis and post-surgery recurrence are disclosed herein. Among the candidate molecular target genes, ECT2, CDC45L and DKK1 are further characterized. Treatment of ESCC cells with small interfering RNAs (siRNAs) of ECT2 or CDC45L suppressed growth of the cancer cells. Thus, the data herein provide valuable information for identifying diagnostic systems and therapeutic target molecules for esophageal cancer.
    • 为了鉴定涉及食管癌发生的分子以及可用于诊断标志物以及新药和免疫治疗靶标的分子,构建了代表32,256个基因的cDNA微阵列,分析19例食管鳞状细胞癌(ESCCS)的表达谱 )通过激光捕获显微切割纯化。 本文公开了在食管癌中显着上调或下调的基因组的详细全基因组数据库。 这些基因可用于治疗药物或免疫治疗以及肿瘤标志物的开发。 此外,本文公开了与淋巴结转移和手术后复发相关的基因。 在候选分子靶基因中,进一步表征ECT2,CDC45L和DKK1。 用ECT2或CDC45L的小干扰RNA(siRNA)处理ESCC细胞抑制癌细胞的生长。 因此,本文的数据提供了用于鉴定诊断系统和用于食管癌的治疗靶分子的有价值的信息。
