Identification, monitoring and treatment of disease and characterization of biological condition using gene expression profiles
First Claim
1. A method, for evaluating a biological condition of a target population of cells affected by an agent based on a sample from the population of cells, the sample providing a source of RNAs, the method comprising:
- using amplification to determine a quantitative measure of the amount of RNA of at least two constituents from any one of Tables 1 through 12 from the sample of the target population of cells, where a panel of constituents is selected so that measurement of the constituents enables measurement of the biological condition and wherein the measures of all constituents in the panel form a first profile data set;
using amplification to determine a quantitative measure of the amount of RNA of all constituents in said panel wherein measures of all constituents in the panel are from a relevant population of target cells and form a normative baseline profile data set, wherein the measures for each constituent are performed under measurement conditions that are (i) within a degree of repeatability of better than ten percent and (ii) the efficiencies of amplification for all constituents differ by less than 10 percent; and
producing a calibrated profile data set for said panel, wherein each member of the calibrated profile data set is a function of a corresponding member of the first profile data set and the corresponding member of a baseline profile data set; and
wherein the calibrated profile data set provides a measure of the biological condition of the target population of cells as affected by the agent.

Abstract
Gene expression data, in particular gene expression profiles, are created and used in the identification, monitoring and treatment of disease and characterization of biological conditions. Profile data sets are derived from subject samples and include quantitative substantially repeatable measures of a distinct amount of RNA or protein constituent in a panel selected to enable evaluation of a biological condition. Such profile data sets may be used to provide an index indicative of the biological state of a subject, which may be compared to a normative value of the index determined with respect to a relevant population of subjects.
