Abstract:
1. A method for identifying a group of miRNAs for use in expression assays, the method comprising the steps of: (1) carrying out a plurality of expression assays, each expression assay comprising the steps of: carrying out at least one intervention on a biological system comprising cultured cells or ex vivo tissue, measuring an expression profile of a group of miRNAs in the biological system resulting from the at least one intervention, and storing an expression data set derived from the measured expression profile, the said expression assays concerning a plurality of different interventions; (2) analysing the resulting expression data sets to determine correlations between the effect on the expression profile of miRNAs of the at least one intervention in groups of two or more expression assays concerning the plurality of different interventions; (3) identifying a sub-group of the group of miRNAs having expression profiles on which the plurality of different interventions have a correlated effect; and (4) selecting the sub-group of miRNAs for use in further expression assays in which the expression profile of a reduced group of miRNAs is measured, the reduced group including only some of the group of miRNAs including at least the identified sub-group of miRNAs, wherein the at least one intervention comprises the application to the biological system of at least one of a group comprising: ionizing radiation; continuously emitted or pulsed electromagnetic radiation; acoustic energy; mechanical intervention; the application of pressure, magnetic fields, or electricity; changes in temperature; changes in osmolarity, tonicity or pH of a growth medium; changes in fluid dynamics; and mechanochemical signal transduction.
