126 results about "Cancer biomarkers" patented technology

A cancer biomarker refers to a substance or process that is indicative of the presence of cancer in the body. A biomarker may be a molecule secreted by a tumor or a specific response of the body to the presence of cancer. Genetic, epigenetic, proteomic, glycomic, and imaging biomarkers can be used for cancer diagnosis, prognosis, and epidemiology. Ideally, such biomarkers can be assayed in non-invasively collected biofluids like blood or serum.

Detection And Quantification Of Biomarkers Via A Piezoelectric Cantilever Sensor

Quantification of a target analyte is performed using a single sample to which amounts of the target analyte are added. Calibration is performed as part of quantification on the same sample. The target analyte is detectable and quantifiable using label free reagents and requiring no sample preparation. Target analytes include biomarkers such as cancer biomarkers, pathogenic Escherichia coli, single stranded DNA, and staphylococcal enterotoxin. The quantification process includes determining a sensor response of a sensor exposed to the sample and configured to detect the target analyte. Sensor responses are determined after sequential additions of the target analyte to the sample. The amount of target analyte detected by the sensor when first exposed to the sample is determined in accordance with the multiple sensor responses.

Early detection and prognosis of colon cancers

We have developed a transcriptome-wide approach to identify genes affected by promoter CpG island hypermethylation and transcriptional silencing in colorectal cancer (CRC). By screening cell lines andvalidating tumor specific hypermethylation in a panel of primary human CRC samples, we estimate that nearly 5% of all known genes may be promoter methylated in an individual tumor. When directly compared to gene mutations, we find a much larger number of genes hypermethylated in individual tumors, and much higher frequency of hypermethylation within individual genes harboring either genetic or epigenetic changes. Thus, to enumerate the full spectrum of alterations in the human cancer genome, and facilitate the most efficacious grouping of tumors to identify cancer biomarkers and tailor therapeutic approaches, both genetic and epigenetic screens should be undertaken. The genes we identified can be used inter alia diagnostically to detect cancer, pre-cancer, and likelihood of developing cancer.

Device for capture, enumeration, and profiling of circulating tumor cells

Applications in nanomedicine, such as diagnostics and targeted therapeutics, rely on the detection and targeting of membrane biomarkers. The present invention, in one embodiment, utilizes quantitative profiling, spatial mapping, and multiplexing of cancer biomarkers using functionalized quantum dots. This approach provides highly selective targeting molecular markers for pancreatic cancer with extremely low levels of non-specific binding and provides quantitative spatial information of biomarker distribution on a single cell, which is important since tumors cell populations are inherently heterogeneous. The quantitative measurements (number of molecules per square micron) is validated using flow cytometry and demonstrated using multiplexed quantitative profiling using color-coded quantum dots.

Analysis of exosomes and methods of diagnosing cancer

The invention relates to quantification, isolation, and characterization of exosomes. In some embodiments, exosomes can be quantified by contacting a sample with a capture bead comprising a bead and afirst binding agent, and a second binding agent. The first binding agent binds to a first biomolecule in the exosomes to produce a first complex and the second binding agent binds to a second biomolecule in the exosomes of the first complex to produce a second complex. The first complexes and the second complexes are quantified based on a detectable signal conjugated to the second binding agent.A microwell or a droplet generation is utilized to quantify the first complexes and the second complexes. In optional embodiments, quantification of the exosomes is used to diagnose a cancer in a subject. In such methods, the first and the second binding agents bind to cancer biomarkers present in the exosomes.
