Abstract
The present invention provides for a method of using CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog kinase antagonists to inhibit hedgehog signaling, as well as treating and diagnosing disorders relating to hedgehog signaling or overexpression of hedgehog, including cancer, cell proliferative disorders, and angiogenesis, neurological disorders, as well as other conditions affected by hedgehog signaling such as hair growth, neural stem cell differentiation, chondrogenesis and osteogenesis, lung surfactant production, formation of lamellated bodies in lung cells.
Claims41
A method for inhibiting hedghog signaling in a cell, comprising contacting a cell in which hedgehog signaling is active with an effective amount of a CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog kinase antagonist.
A method of preventing the proliferation, growth, differentiation or survival of cell with an active hedgehog signaling pathway, comprising contacting said cell with an effective amount of a CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog kinase antagonist.
A method of inhibiting the growth of a cancer cell, wherein the growth of said cancer cell is at least in part dependent upon the growth potentiating effect(s) of a CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog polypeptide, wherein the method comprises contacting the hedgehog polypeptide with a CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog kinase antagonist, respectively, thereby antagonizing the growth-potentiating activity of the hedgehog polypeptide and as a result, inhibits the growth of the cancer cell.
A method for diagnosing the presence of a cell proliferative disorder comprising comparing the level of expression of a gene encoding a CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog kinase polypeptide:
- (a) in a test sample of tissue or cells obtained from said mammal, and (b) in a control sample of known normal non-cancerous tissue or cells of the same tissue origin or type;
- wherein a higher expression level of the CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK polypeptide in the test sample, as compared to the control sample, is indicative of the presence of a cell proliferative disorder in the mammal from which the test sample was obtained.
A method for treating or preventing a cell proliferative disorder associated with increased expression or activity of hedgehog signaling, comprising administering to a subject in need of such treatment a therapeutically effective amount of a CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog kinase antagonist.
A method of therapeutically treating a tumor in a mammal, comprising cells in which the growth of said tumor is at least in part dependent upon the growth poteniating effect(s) of a hedgehog polypeptide and the modulation thereof by a CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2, TTK polypeptide, comprising administering to the mammal a therapeutically effective amount of a CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog kinase antagonist, thereby antagonizing the growth potentiating activity of the hedgehog polypeptide and resulting in the effective therapeutic treatment of the tumor.
A method of treating cancer comprising contacting a cancer cell or tissue with an effective amount of a CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog kinase antagonist.
A method of inhibiting angiogenesis comprising contacting a cell or tissue in which angiogenesis is to be inhibited with an effective amount of a CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog kinase antagonist.
A method of modulating the proliferation, differentiation or survival of uncommitted stem cells in culture comprising contacting such cells with an effective amount of a CDC2L 1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog kinase antagonist.
A method of modulating the proliferation, differentiation or survival of cells in a patient suffering from (a) a neurological disorder, (b) undergoing chondrogenesis or osteogenesis, or undergoing hair regeneration or regrowth, comprising contacting such cells with an effective amount of a CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog kinase antagonist.
A method of stimulating surfactant production in a lung cell, comprising contacting said cell with a CDC2L1, CSNK1A1, GYK, NEK1, PLK1, PRKAR1A, PRKRA, TTBK2 or TTK hedgehog kinase antagonist in an amount effective to stimulate surfactant production.
