  • Publication number: 20230160018
    Abstract: CKYPB2 induces EMT, sternness, protein synthesis and cell cycle progression through regulation of nucleolin, con-tributing to an increase in tumor growth and metastasis. CKYPB2 can be used as a prognostic marker in African American women with TNBC. CKYPB2 can further select patients with TNBC and ER positive tumors that will likely benefit from inhibitors of ribosomal RNA synthesis, CDK4 and nucleolin.

  • Publication number: 20200190586
    Abstract: The cMethDNA method of the present invention is a novel modification of the QM-MSP method (U.S. Pat. No. 8,062,849), specifically intended to quantitatively detect tumor DNA (or other circulating DNAs) in fluids such as serum or plasma at the lowest copy number yet reported. Unique compared to any other PCR-based assay, a small number of copies of a synthetic polynucleotide standard (STDgene) is added to an aliquot of patient serum. In a standard procedure, a cocktail of standards for a plurality of genes of interest (TARGETgene) is added to a sample of serum. Once total DNA is purified and processed, a PCR (multiplex step) is performed wherein the STDgene and the TARGETgene are co-amplified with the same external primer set. In the second nested PCR step, amplicons present in a dilution of the first PCR reaction are subjected to real time PCR, and quantified for each gene in one well by two-color real-time PCR.

  • Patent number: 9540694
    Abstract: The invention generally features compositions and methods that are useful for treating or diagnosing a neoplasia, in particular breast neoplasia. The invention is based in part on the observation that the basic helix loop helix transcription factor HEYL was found to be overexpressed in breast cancer cells. Accordingly, the invention provides therapeutic compositions and methods for altering the levels and expression of HEYL of the invention, thereby treating a neoplasia, as well as compositions and methods for diagnosing a neoplasia.

  • Patent number: 9416404
    Abstract: Methods are provided for diagnosing in a subject a condition, such as a carcinoma, sarcoma or leukemia, associated with hypermethylation of genes by isolating the genes from tissue containing as few as 50 to 1000 tumor cells. Using quantitative multiplex methylation specific PCR (QM-MSP), multiple genes can be quantitatively evaluated from samples usually yielding sufficient DNA for analyses of only 1 or 2 genes. DNA sequences isolated from the sample are simultaneously co-amplified in an initial multiplex round of PCR, and the methylation status of individual hypermethylation-prone gene promoter sequences is then determined separately or in multiplex using a real time PCR round that is methylation status-specific. Within genes of the panel, the level of promoter hypermethylation as well as the incidence of promoter hypermethylation can be determined and the level of genes in the panel can be scored cumulatively. The QM-MSP method is adaptable for high throughput automated technology.

  • Publication number: 20150315269
    Abstract: To gain a better understanding of breast tumor angiogenesis, breast endothelial cells (ECs) were isolated and evaluated for gene expression patterns. When transcripts from breast ECs derived from normal and malignant breast tissues were compared, genes that were specifically elevated in tumor-associated breast endothelium were revealed. These results confirm that neoplastic and normal endothelium in human breast are distinct at the molecular level, and have significant implications for the development of anti-angiogenic therapies in the future.

  • Patent number: 9062308
    Abstract: The inventors found that the gene, HOXB7, was frequently overexpressed in breast cancer, and is a major upstream regulator of events leading to tamoxifen resistance. The present invention provides double-stranded short interfering nucleic acid (siNA) molecules that targets the HOXB7 gene in cells, and also provides methods of use of this siNA molecule for methods of screening, diagnosis and prediction of treatment outcomes as well as treatment of cancer.
