A flaviviral replicon-based construct is provided for delivery and expression of granulocyte-macrophage colony stimulating factor to facilitate tumour therapy. In particular, the replicon construct encodes a Kunjin virus replicon having one or more mutations in an NS2A non-structural protein that induce enhanced levels of cellular IFN that synergize with recombinant granulocyte-macrophage colony stimulating factor delivered according to the invention. The construct may be administered intra-tumourally or peri-tumourally to an animal as DNA, RNA or packaged into a VLP, for the therapeutic and / or prophylactic treatment of tumours and cancers such as melanoma, lung carcinoma, cervical carcinoma, lung epithelial carcinoma, prostate cancer, breast cancer, renal carcinoma, colon cancer, epithelial cancers and mesothelioma.

The present invention relates to a class of compounds having affinity for certain cancer cells, e.g. lung carcinomas, colon carcinomas, renal carcinomas, prostate carcinomas, breast carcinomas, malignant melanomas, gliomas, neuroblastomas and pheochromocytomas. The compounds of the present invention can also bind with high specificity to cell surface sigma receptors and can therefore be used for diagnostic imaging of any tissue having an abundance of cells with sigma receptors. The present invention provides such compounds as agents for diagnostic imaging and for detecting and treating tumors containing the cancer cells described above.

The present invention provides a DNA encoding a novel extracellular serine protease termed Tumor Antigen Derived Gene-14 (TADG-14) which is overexpressed in ovarian, breast and colon carcinoma samples. Also provided are vector and host cells capable of expressing the DNA of the present invention, as well as the uses of the DNA and protein of the present invention. Also provided is a TADG-14 protein variant that has a potential role for detecting and targeting of ovarian carcinomas.

The invention provides a human colon carcinoma cell line DXH-1, which is derived from primary lesion of human sigmoid colon carcinoma, and application of the human colon carcinoma cell line as a human colon carcinoma occurrence, human colon carcinoma development or human colon carcinoma transfer cell model, application of the human colon carcinoma cell line in establishing a human colon carcinoma animal model and application of the human colon carcinoma cell line in researching a human colon carcinoma occurrence mechanism and / or medicines for treating the human colon carcinoma. The human colon carcinoma cell line DXH-1 disclosed by the invention can be stably transferred for more than 50 generations, so that an appropriate material is provided for colorectal carcinoma mechanism and drug screening. In an in-vivo nude mice experiment, the human colon carcinoma cell line shows a relatively strong tumorigenesis cavity, and the cell line, transplanted subcutaneously in nude mice by 1*106 cells, is capable of promoting 100% (5 / 5) tumorigenesis after 35 days; the DXH-1 cell has certain drug resistance to colon carcinoma chemotherapeutics (5FU, such as oxaliplatin, irinotecan and the like), so that a material is provided to the researches on a colon carcinoma chemotherapeutic resistance mechanism; and the human colon carcinoma cell line DXH-1 is preserved in China Center for Type Culture Collection in Wuhan University, Wuhan, China with number of CCTCC No: C201543.

Phage display was used to screen peptide libraries that distinguish between well-differentiated (HCT116) and poorly-differentiated colon carcinoma cells (HT29). The screening protocol used selection and subtraction on intact, viable cells, resulting in phage libraries exhibiting high binding selectivity for the poorly-differentiated HT29 cells. A nine amino acid, disulfide-constrained peptide (RPM) was identified that selectively bound and was internalized into colon cancer cells. The peptide may be used to detect colon cancer cells and also may be used to selectively deliver therapeutic agents to the cells.

The invention relates to preparation and application of a novel organo-antimony complex (1). The complex (1) has the characteristics of high anticancer activity, large water solubility, small toxic side effect and the like. A drug effect composition containing the complex (1) is used for treating various solid cancers, such as lung cancer, gastric carcinoma, liver cancer, breast carcinoma, cancer of colon, ovarian cancer, cervical carcinoma, leukemia, lymphoma, nasopharyngeal darcinoma and the like.

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.

The present invention relates to a method aiding in the assessment of cancer. It discloses the use of the human fibroblast activation protein (FAP / seprase) as a universal marker of different cancer types. Seprase aids in the assessment of pulmonary or lung cancer (LC) or of colon cancer, e.g., of non-small cell lung carcinoma (NSCLC) or colorectal cancer (CRC), but also likely of other specific types of cancer. Such specific cancer types are, e.g., esophagus, head and neck cancer, stomach cancer, bile duct cancer, pancreas cancer, kidney cancer, cervix cancer, ovary cancer, breast cancer, bladder cancer, endometrium cancer or prostate cancer. Furthermore, it especially relates to a method for assessing cancer from a liquid sample, derived from an individual by measuring seprase in said sample. Measurement of seprase can, e.g., be used in the early detection of cancer or in the surveillance of patients who undergo surgery.
