The present invention provides prognostic and diagnostic methods for cancer, as well as methods for monitoring or staging cancer. Methods involve assaying for tumor-derived soluble MIC polypeptide—either MICA or MICB or both—in a sample from a subject. Assays can be implemented with a MIC polypeptide binding agent such as a MIC polypeptide antibody or recombinant NKG2D. An ELISA sandwich assay is employed in some embodiments of the invention to identify a soluble MIC polypeptide. In additional embodiments, a sample is assayed for tumor cell-surface bound MIC in addition to assaying for soluble MIC. The invention also provides methods of cancer therapy involving detecting cancer in the subject by assaying for soluble MIC polypeptide and then administering a cancer therapy.

The present invention is a method for the treatment of cancer involving tumor derived immunosuppression in a subject. The method comprises administering to a subject one or more siRNA constructs capable of inhibiting the expression of an immunosuppressive molecule. The invention also provides siRNA constructs and compositions.

To gain a better understanding of tumor angiogenesis endothelial cells (ECs) were isolated and gene expression patterns were evaluated. When transcripts from ECs derived from normal and malignant colorectal tissues were compared with transcripts from non-endothelial cells, over 170 genes predominantly expressed in the endothelium were identified. Comparison between normal- and tumor-derived endothelium revealed differentially expressed genes, including many that were specifically elevated in tumor-associated endothelium. Experiments with representative genes from this group demonstrated that most were similarly expressed in the endothelium of primary lung, breast, brain, and pancreatic cancers as well as in metastatic lesions of the liver. These results demonstrate that neoplastic and normal endothelium in humans are distinct at the molecular level.

This invention relates to the use of tumor-derived or associated extracellular ribonucleic acid (RNA) found circulating in the plasma or serum fraction of blood for the detection, monitoring, or evaluation of cancer or premalignant conditions. Extracellular RNA may circulate as non-bound RNA, protein-bound RNA, lipid-RNA complexes, lipoprotein (proteolipid)-RNA complexes, protein-RNA complexes including within or in association with ribonucleoprotein complexes, nucleosomes, or within apoptotic bodies. Any intracellular RNA found in plasma or serum can additionally be detected by this invention. Specifically, this invention enables the extraction of circulating RNA from plasma or serum and utilizes nucleic acid amplification assays for the identification, detection, inference, monitoring, or evaluation of any neoplasm, benign, premalignant, or malignant, in humans or other animals, which might be associated with that RNA. Further, this invention allows the qualitative or quantitative detection of tumor-derived or associated extracellular RNA circulating in the plasma or serum of humans or animals with or without any prior knowledge of the presence of cancer or premalignant tissue.
