This invention relates to methods of inhibiting the growth of cancer cells that overexpress a Wnt protein. The methods comprise contacting the cell with an agent that inhibits binding of the Wnt protein to a Frizzled receptor.

The present invention discloses osteogenic and anti-adipogenic oxysterols. Agents and methods for protecting, blocking or rescuing marrow stromal cells from the inhibitory effects of oxidative stress on their osteoblastic cellular differentiation are disclosed. Exemplary agents include oxysterols alone or in synergistic combinations, as well as hedgehog or Wnt signaling activators. The synergistic effects of oxysterols and bone morphogenic proteins are also disclosed.

Compositions and methods for modulating proliferation and/or lineage commitment of stem cells by modulating the Wnt signalling pathways. Modulators of the Wnt signalling pathways and screening methods to identify modulators are also provided. The methods of the invention may be conducted in vitro or in vivo to induce or inhibit stem cell proliferation and/or lineage commitment, and are particularly useful for in vivo stimulation of proliferation and/or lineage commitment of resident stem cells in a tissue.

The present invention provides in vitro systems for use in identifying modulators of neural differentiation. Also provided are modulators identified by these systems. The present invention further provides methods for identifying a modulator of neural differentiation, a modulator of a Wnt signalling pathway, a modulator of Wnt-dependent neural differentiation, a modulator of a BMP signalling pathway, a modulator of BMP-dependent neural differentiation, a modulator of a Hh signalling pathway, and a modulator of Hh-dependent neural differentiation. Also provided are modulators identified by these methods.

An ex vivo method for preparing a population of induced paraxial mesoderm progenitor (iPAM) cells includes culturing pluripotent cells in an appropriate culture medium that includes an effective amount of an activator of the Wnt signalling pathway.

The present invention relates to a method of treating or preventing a disease characterized by excessive Wnt signalling, such as colorectal cancer, by administering a compound which inhibits the activity of one or more of JAK2, JAK1 or TYK2.

The present invention relates to methods of diagnosis and treatment of corneal ectasia following refractive surgery, keratoconus or pellucid marginal degeneration in a subject by determining or modulating the level of expression of molecules associated with the Wnt signalling pathway. Marker molecules of the present invention include SFRP1, PITX2, LEF1, WNT16 and WNT5A.

The present invention relates to directed differentiation and maturation of hepatocyte-like cells. In particular, the present invention relates to exposure of hepatocyte-like cells to an activator of a retinoic acid responsive receptor, such as retinoic acid (RA), optionally in combination with an inhibitor of GSK-3 (Glycogen synthase kinase 3) or activator of Wnt signalling and/or with the overlay of the cells with one or more components characteristic of the mammalian extracellular matrix (matrix overlay). The present invention also relates to exposure of hepatocyte-like cells to an activator of a retinoic acid responsive receptor, such as retinoic acid (RA), optionally in combination with an inhibitor of a cycline dependent kinase (CDK) and/or with the overlay of the cells with one or more components characteristic of the mammalian extracellular matrix (matrix overlay). The hepatocyte-like cells obtained in accordance with the present invention show a phenotype which is more similar to that of primary hepatocytes than previously shown.

Disclosed herein are biomarkers related to WNT signal transduction pathway, as well as methods and kits comprising the same. Further, the present disclosure relates to the use of the biomarkers in patient selection, companion diagnostics, and treatment of cancer.

The present invention is directed to the use of macrocyclic lactones, in particular avermectins, in the treatment of conditions whose formation, occurrence, development or growth is associated with aberrant Wnt signalling in particular the treatment of colorectal cancer.

The present disclosure relates to isolated polypeptides that inhibit Wnt signaling, pharmaceutical compositions comprising the isolated polypeptides, and methods of use thereof. Nucleic acids, cells,and methods of production related to the isolated polypeptides and compositions are also disclosed.

The present invention pertains generally to the field of therapeutic compounds. More specifically the present invention pertains to certain 3-aryl-5-substituted-2/-/-isoquinolin-1-one compounds that, inter alia, inhibit PARP (e.g., PARP1, TNKS1, TNKS2, etc.) and/or Wnt signalling. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit PARP (e.g., PARP1, TNKS1, TNKS2, etc.); to inhibit Wnt signalling; to treat disorders that are ameliorated by the inhibition of PARP (e.g., PARP1, TNKS1, TNKS2, etc.); to treat disorders that are ameliorated by the inhibition of Wnt signalling; to treat proliferative conditions such as cancer, etc.
