  • Publication number: 20220403474
    Abstract: Provided herein are methods of determining tumoral sensitivity to hormonal (endocrine) therapy based upon an index of estrogen receptor (ER)- and progesterone receptor (PR)-related genes, referred to as the sensitivity to endocrine therapy index (SETER/PR index), and may have additional consideration for the proportion of ER gene (ESR1) RNA transcripts that contain a mutation relative to the value of the SETER/PR index.

  • Publication number: 20150368721
    Abstract: The present invention provides the identification and combination of genes that are expressed in tumors that are responsive to a given therapeutic agent and whose combined expression can be used as an index that correlates with responsiveness to that therapeutic agent. One or more of the genes of the present invention may be used as markers (or surrogate markers) to identify tumors that are likely to be successfully treated by that agent or class of agents such as hormonal or endocrine therapy or chemotherapy.

  • Publication number: 20100178651
    Abstract: The present invention provides the identification of genes that are expressed in tumors to indicate responsiveness or resistance to an agent or class of agents. More particularly, these genes show expression associated with responsiveness to one agent or class of agents is inversely related to expression in association with another class of agents. One or more of theses genes of the present invention can be used as markers (or surrogate markers) to identify tumors that are likely to be successfully treated by the responsive agent as well as to identify tumors that should avoid treatment by the resistant agent.

  • Patent number: 7711494
    Abstract: Disclosed is a method for determining survival and relapse of a patient undergoing therapy for a tumor by determining a residual cancer burden index based on the bidimensional diameters of a primary tumor bed of said tumor in a resection specimen, the proportion of the primary tumor bed area that contains invasive carcinoma, the number of regional lymph nodes containing metastatic carcinoma, the diameter of the largest metastasis in an regional lymph node; and the fractional reduction in lymph node size with each added positive lymph node.

  • Publication number: 20030124548
    Abstract: The present invention provides methods for identifying relationships between gene expression and protein modifications in a cell by determining gene expression generated in the cell, determining protein modifications generated in the cell, and coordinating the gene expression and protein modifications generated in the cell. Also provided by the present invention is a computer system for identifying such a relationship between gene expression and protein modifications. The present inventive methods and computer systems are useful for investigating a variety of physiological or pathophysiological processes, including metabolic pathways, typing of diseased cells, and identifying biological activities of test materials.

  • Patent number: 6022419
    Abstract: A multi-function process is described for the hydrolysis and fractionation of lignocellulosic biomass to separate hemicellulosic sugars from other biomass components such as extractives and proteins; a portion of the solubilized lignin; cellulose; glucose derived from cellulose; and insoluble lignin from said biomass comprising one or more of the following: optionally, as function 1, introducing a dilute acid of pH 1.0-5.0 into a continual shrinking bed reactor containing a lignocellulosic biomass material at a temperature of about 94 to about 160.degree. C. for a period of about 10 to about 120 minutes at a volumetric flow rate of about 1 to about 5 reactor volumes to effect solubilization of extractives, lignin, and protein by keeping the solid to liquid ratio constant throughout the solubilization process; as function 2, introducing a dilute acid of pH 1.0-5.
