Abstract: The invention provides methods for inhibiting angiogenesis in an animal in need thereof. The invention also pro-vides methods for preventing tumor growth and metastasis in an animal comprising inhibiting FoxM1B activity.

Abstract: The invention provides a method of preventing or amelioriating age-related proliferation defects or age-related diseases in a patient by stimulating FoxM1B protein expression, nuclear localization, or both protein expression and nuclear localization of FoxM1B or by introducing a recombinant nucleic acid construct that comprises a truncated FoxM1B gene into target cells, thereby restoring proliferative potential of the target cells. The invention also provides a method of treating diseases or disorders associated with premature aging. The invention further provides a method of treating or ameliorating lung damage. Specifically, the methods of the invention comprise inducing expression and nuclear localization of FoxM1B protein in a target cell by contacting the cell with a growth factor or a cytokine.

Abstract: The invention provides a method of treating liver damage or disease in a patient by stimulating liver regeneration. Specifically, the invention provides a method of inducing liver cell proliferation comprising contacting liver cells that express FoxM1B protein with growth hormone. The invention also provides methods of screening for compounds that induce FoxM1B protein expression, nuclear localization, or both expression and nuclear localization. The invention further provides pharmaceutical compositions comprising selected compounds and methods of using such compositions.
