Patent ID: 7125664

Claim:
A method for identifying a regulator gene that regulates the expression of a pre-selected gene of interest, comprising the steps of: placing a sample containing genetic material in a grid having multiple sections, wherein the genetic material comprises the pre-selected gene of interest and at least one predetermined gene; silencing expression of at least one predetermined gene in the sample, wherein at least one predetermined gene is silenced in each section of the grid and in multiple sections of the grid, different predetermined genes are silenced; determining the level of expression of the pre-selected gene of interest for each section of the grid after the predetermined gene is silenced; identifying the sections of the grid in which the expression of the pre-selected gene of interest is increased or decreased as compared to a control; and recognizing the revealed predetermined gene of those sections of the grid wherein the expression of the pre-selected gene of interest is increased or decreased as a regulator gene of the pre-selected gene of interest.
