    • The invention provides a method of modulating a regulatory state of a cell. The method consists of: (a) identifying a point of interdiction within a cis regulatory network specifying a genetic regulatory architecture of a cell, and (b) introducing into a progenitor cell two or more network elements within said network to induce a predetermined series of cis regulatory network interactions resulting in a specified regulatory state of said progenitor cell. Also provided is a method of modulating a regulatory state of a cell. The method consists of: (a) identifying a point of interdiction within a cis regulatory network specifying a genetic regulatory architecture of a cellular state, and (b) introducing into a progenitor cell two or more network elements within said network to induce a predetermined series of cis regulatory network interactions resulting in a specified regulatory state of said progenitor cell. A cell having a specified regulatory state consisting of a modified genetic regulatory architecture is further provided. Methods of diagnosing and methods of treating an individual suffering from a cellular defect also are provided. The invention additionally provides a method of identifying a compound having differentiation or cell fate inducing activity.

    • Transfection of confluent cells or other slowly dividing or non-dividing cells that are in contact with each other with a nucleic acid using a non-viral receptor targeted vector may be improved by the concurrent use of an agent that disrupts cell-cell junctions, especially EGTA. The vector is especially an integrin-targeting transfection vector complex comprising (i) a nucleic acid, especially a nucleic acid encoding a sequence of interest, (ii) an integrin-binding component, especially an integrin-targeting peptide, (iii) a polycationic nucleic acid-binding component, especially an oligolysine, and (iv) a lipid component, especially, DOPE, DOTMA, DOSPA or combinations thereof. Various applications of the improved method of transfection are described.

    • The present invention relates to the targeted delivery of a delivery vehicle construct which specifically binds to and stimulates endocytosis into cells expressing the urokinase plasminogen activator receptor (uPAR), and particularly human airway epithelia. The delivery vehicle construct comprises a portion of uPA and a cargo linked thereto and is useful for the targeted delivery of the cargo to a cell. In one aspect of the invention, the uPA portion of the delivery vehicle construct comprises the wild-type uPA, a fragment of uPA which has the PAI-1 binding region deleted, or a uPA peptide comprising amino acids 13-19 and is useful for the targeted delivery of the cargo to cells, and in particular to airway epithelia. The present invention also provides a method for delivering the delivery vehicle construct to a cell. The method comprises the steps of (a) contacting a target cell with a delivery vehicle construct comprising a uPA portion and a cargo portion; and (b) obtaining a desired result in the target cell.
