  • Publication number: 20110098341
    Abstract: The invention relates to a method of determining whether a human subject is suffering from or at risk for developing pancreatic cancer by determining the methylation level of an ID4 gene promoter or the expression level of an ID4 gene in a biological sample from a human subject. Also disclosed are a method of analyzing the methylation level of an ID4 gene promoter or the expression level of an ID4 gene in a pancreatic cancer cell, and a method of inhibiting the methylation of an ID4 gene promoter or enhancing the expression of an ID4 gene by contacting a pancreatic cancer cell with a compound that decreases the methylation level of an ID4 gene promoter or increases the expression level of an ID4 gene in the cell.

  • Patent number: 7910295
    Abstract: The invention provides a quantitative realtime RT-PCR assay for detection of metastatic breast, gastric, pancreas or colon cancer cells or metastatic melanoma. The assay allows to predict disease recurrence and survival in patients with AJCC stage I and II, and III disease using multimarker panels. The method for detecting metastatic melanoma cells utilizes panels of markers selected from a group consisting of MAGE-A3, GalNAcT, MART-1, PAX3, Mitf, TRP-2, and Tyrosinase. The method for detecting metastatic breast, gastric, pancreas or colon cancer cells in paraffin-embedded samples utilizes panels of markers selected from a group consisting of C-Met, MAGE-A3, Stanniocalcin-1, mammoglobin, HSP27, GalNAcT, CK20, and ?-HCG.

  • Patent number: 7897336
    Abstract: The present invention describes a method for identification and labeling of sentinel lymph nodes (SLNs) and the presence or absence of lymph node metastases as an important diagnostic and prognostic factor in early stage cancers of all types. The method, know as Molecular Lymphatic Mapping, uses traditional dye/radioactive tracer based techniques in conjunction with a nucleic acid marker to identify and label the SLN, not only for current diagnostic methods, but for archival purposes. In addition, MLM can be used to deliver a therapeutic gene or genes to the SLN to activate tumor immunity to tumor cells, and/or to inhibit tumor metastases. The methods may be combined with therapeutic intervention including chemotherapy and radiotherapy.

  • Publication number: 20100330567
    Abstract: A method is provided for assessing allelic losses and hypermethylation of genes in CpG tumor promotor region on specific chromosomal regions in cancer patients, including melanoma, neuroblastoma breast, colorectal, and prostate cancer patients. The method relies on the evidence that free DNA and hypermethylation of genes in CpG tumor promotor region may be identified in the bone marrow, serum, plasma, and tumor tissue samples of cancer patients. Methods of melanoma, neuroblastoma, colorectal cancer, breast cancer and prostate cancer detection, staging, and prognosis are also provided.
