Identification, monitoring and treatment of disease and characterization of biological condition using gene expression profiles
First Claim
1. A method of providing an index that is indicative of the state of a subject, as to a biological condition characterized by inflammation, based on a sample from the subject, the method comprising:
- using amplification for measuring the amount of RNA or constituents from the sample of the subject, where a panel of constituents is selected so that measurement of the constituents enables evaluation of said biological condition and the measures of all constituents in the panel form a first profile data set, wherein the measures for each constituent are performed under measurement conditions that are substantially repeatable and the efficiencies of amplification for all constituents are substantially similar; and
applying values from said first profile data set to an index function I=Σ
CiMiP(i) where I is the index, Mi is the value of the member i of the profile data set, Ci is a constant, and P(i) is a power to which Mi is raised, the sum being formed for all integral values of i up to the number of members in the data set, thereby providing a single-valued measure of the biological condition so as to produce art index pertinent to the biological condition of the subject.

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.

2. A method of providing an index that is indicative of the state of a subject, as to a biological condition characterized by inflammation, based on a sample from the subject, the sample providing a source of RNAs, the method comprising:
-
using amplification for measuring the amount of RNA of at least two constituents from arty one of Tables 1 through 12 from the sample of the subject, where a panel of constituents is selected so that measurement of the constituents enables evaluation of said biological condition and wherein the measures of all constituents in the panel form a first profile data set, wherein the measures for each constituent are performed under measurement conditions that are substantially repeatable and the efficiencies of amplification for all constituents are substantially similar; and
applying values from said first profile data set to an index function I=Σ
CiMiP(i) where I is the index, Mi is the value of the member i of the profile data set, Ci is a constant, and P(i) is a power to which Mi is raised, the sum being formed for all integral values of i up to the number of members in the data set, thereby providing a single-valued measure of the biological condition so as to produce an index pertinent to the biological condition of the subject.
