Abstract:
The present application provides novel human genes WDRPUH and KRZFPUH, and PPIL1 whose expression is markedly elevated in a great majority of HCCs and colorectal cancers, respectively, compared to corresponding non-cancerous tissues, as well as novel human gene APCDD1 whose expression is elevated in primary colon cancers and down-regulated in response to the transduction of wild-type APC1 into colon-cancer cells. The genes and polypeptides encoded by the genes can be used, for example, in the diagnosis of a cell proliferative disease, and as target molecules for developing drugs against the disease.
Abstract:
Objective methods for detecting and diagnosing intestinal-type gastric cancers are described herein. Also described is method for predicting the presence or absence of lymph node metastasis (i.e., identifying the metastatic phenotype). In one embodiment, the diagnostic method involves the scoring of gene expression profiles that discriminate between lymph node positive tumors and lymph node negative tumors. The predictive score calculated acts as diagnostic indicator that can objectively indicate whether a sample tissue has the metastatic phenotype. The present invention further provides methods of diagnosing intestinal-type gastric cancer in a subject, methods of screening for therapeutic agents useful in the treatment of intestinal-type gastric cancer, methods of treating intestinal-type gastric cancer and method of vaccinating a subject against intestinal-type gastric cancer.
Abstract:
The present invention provides a diagnostic marker to detecting lung cancer. In particular, the present invention provides lung cancer marker genes i.e. KIF4A, MAPJD, NPTX, or FGFR1OP. The present invention further provides methods and kit for identifying compounds for treating lung cancer as well as methods for predicting a prognosis or diagnosis of lung cancer. In particular, the present invention provides methods and kits for identifying inhibitors of the interaction between KIF4A/ZNF549, KIF4A/ZNF553, MAPJD/MYC, or FGFR1OP/WRNIP1 which find utility in the treatment and prevention of lung. Alternatively, the present invention provides MAPJD associated with HAT complex as therapeutic target.
Abstract:
Objective methods for detecting and diagnosing renal cell carcinoma (RCC) are described herein. In one embodiment, the diagnostic method involves determining the expression level of RCC-associated gene that discriminates between RCC cells and normal cells. The present invention further provides methods of screening for therapeutic agents useful in the treatment of renal cell carcinoma, methods of treating renal cell carcinoma and method of vaccinating a subject against renal cell carcinoma.
Abstract:
Objective methods for detecting and diagnosing small cell lung cancer (SCLC) are described herein. In one embodiment, the diagnostic method involves determining the expression level of an SCLC-associated gene that discriminates between SCLC cells and normal cells. In another embodiment, the diagnostic method involves determining the expression level of an SCLC-associated gene that distinguishes two major histological types of lung cancer, non-small cell lung cancer (NSCLC) and SCLC. Finally, the present invention provides methods of screening for therapeutic agents useful in the treatment of small cell lung cancer, methods of treating small cell lung cancer and method for vaccinating a subject against small cell lung cancer. Furthermore, the present invention provides chemotherapy resistant lung cancer- or SCLC-associated genes as diagnostic markers and/or molecular targets for therapeutic agent for these cancers. These genes are up-regulated in chemoresistant lung cancer or SCLC. Accordingly, chemoresistant lung cancer or SCLC can be predicted using expression level of the genes as diagnostic markers. As the result, any adverse effects caused by ineffective chemotherapy can be avoided, and more suitable and effective therapeutic strategy can be selected.
Abstract:
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, a Homo sapiens epithelial cell transforming sequence 2 oncogene (ECT2) and a cell division cycle 45, S. cerevisiae, homolog-like (CDC45L) 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. Furthermore, the present inventors have identified DKK1 as a potential biomarker for diagnosis of cancer such as lung and esophageal cancers as well as prediction of the poor prognosis of the patients with these diseases. DKK1 was specifically over-expressed in most lung and esophageal cancer tissues the present inventors examined, and was elevated in the sera of a large proportion of patients with these tumors. DKK1, combined with other tumor markers, could significantly improve the sensitivity of cancer diagnosis. Moreover, this molecule is also a likely candidate for development of therapeutic approaches such as antibody therapy.

Objective methods of detecting and diagnosing pancreatic cancer (PDAC) are described herein. In one embodiment, the diagnostic method involves determining the expression level of CST6 or GABRP that discriminates between PDAC cells and normal cells. Finally, the present invention provides methods of screening for therapeutic agents useful in the treatment of pancreatic cancer, methods of treating pancreatic cancer and method of vaccinating a subject against pancreatic cancer.
Abstract:
Objective methods for detecting and diagnosing bladder cancer (BLC) are described herein. In one embodiment, the diagnostic method involves determining the expression level of a BLC-associated gene that discriminates between BLC cells and normal cells. The present invention further provides means for predicting and preventing bladder cancer metastasis using BLC-associated genes having unique altered expression patterns in bladder cancer cells with lymph-node metastasis. Finally, the present invention provides methods of screening for therapeutic agents useful in the treatment of bladder cancer, methods of treating bladder cancer and method for vaccinating a subject against bladder cancer. In particular, the present application provides novel human genes C2093, B5860Ns and C6055s whose expression is markedly elevated in bladder cancers. The genes and polypeptides encoded by the genes can be used, for example, in the diagnosis of bladder cancers, as target molecules for developing drugs against the disease, and for attenuating cell growth of bladder cancer.
Abstract:
