Twenty-three markers are provided which are epigenetically silenced in ovarian cancers. The markers can be used diagnostically, prognostically, therapeutically, and for selecting treatments that are well tailored for an individual patient. Restoration of expression of silenced genes can be useful therapeutically, for example, if the silenced gene is a tumor-suppressor gene. Restoration can be accomplished by supplying non-methylated copies of the silenced genes or polynucleotides encoding their encoded products. Alternatively, restoration can be accomplished using chemical demethylating agents or methylation inhibitors. Kits for testing for epigenetic silencing can be used in the context of diagnostics, prognostics, or for selecting “personalized medicine” treatments.

Desvenlafaxine is formed from venlafaxine by the use of a demethylating agent comprising a metal sulfide, such as sodium sulfide, and optionally selenium.

The present provides methods for affecting and / or altering the differentiation state of a cell. In certain embodiments, the present invention provides methods to transdifferentiate a cell into an endothelial cell or a hematopoietic cell. In the practice of the invention, a demethylating agent (e.g., 5-azacytidine) is used to affect and / or alter the differentiation state of a cell. The invention demonstrates the transdifferentiation of numerous cell types, including cell populations that are themselves somewhat differentiated (e.g., normal fibroblasts) into distinct cell types, including hematopoietic cells and endothelial cells, which transdifferentiation is effected further through the selection of particular growth factors which, together with the demethylating agents, directs the differentiation path. The invention provides a novel approach to providing useful cell types for many types of medical applications.

A method of efficiently and conveniently inducing differentiation from bone marrow stromal cells to skeletal muscle cells, which comprises the steps of: (a) the step of adding one or more kinds of substances selected from the group consisting of a cyclic AMP increasing agent, a cAMP analogue, and a cell differentiation stimulating factor to a culture of bone marrow stromal cells, wherein said bone marrow stromal cells are not treated with a demethylating agent, and culturing the cells; (b) the step of introducing a Notch gene and / or a Notch signaling related gene into the cells obtained in the step (a), and culturing the cells to obtain a culture of myoblasts, provided that said culture does not contain the cells introduced with the gene and non-introduced cells; and (c) the step of adding a Notch ligand to the culture of myoblasts obtained in the step (b), and culturing the cells.

The invention describs a method of producing cells for transplantation into myocardial tissue of a mammal. The method comprises the steps: (a) providing bone marrow stem cells that have not been immortalized; (b) passage culturing two times said bone marrow stem cells under conditions that maintain the characteristics of bone marrow stem cells; (c) culturing said bone marrow stem cells in cardiac specific media to differentiate into cardiomyogenic cells; and (d) collecting the cells of step (c) when about 80 to 90% of said cells are cardiomyogenic cells. The cardiomyogenic cells induced according to the method can be clinically applied more suitably than those induced using demethylating agent such as 5-azacytidine, and therefore, they provide induced bone marrow stem cells of a mammal into cardiomyocytes having high rates of cell incorporation and cell survival for treating a mammal (e.g., a human) diagnosed as having a disorder characterized by insufficient cardiac function.

An object of the present invention is to provide a method for transdifferentiating a mature cell without using a DNA methylating agent or a DNA demethylating agent. The present invention provides a method for transdifferentiating a finally differentiated mature cell having a first differentiation phenotype into a finally differentiated mature cell having a second differentiation phenotype that differs from the above first differentiation phenotype by changing culture conditions for the finally differentiated mature cell having the first differentiation phenotype, wherein culture conditions suitable for culturing the finally differentiated mature cell having the above first differentiation phenotype are changed to culture conditions suitable for culturing the finally differentiated mature cell having the above second differentiation phenotype.

Provided herein are pharmaceutical compositions and methods for treating disorders characterized by reduced expression of anti-oxidative stress enzymes in a subject. In one aspect, the present invention provides a method for inducing expression of anti-oxidative stress enzymes in a subject in need thereof. The method includes administering to the subject a therapeutically effective amount of a demethylating agent. The demethylating agent includes a phytochemical that induces expression of Nrf2 and Nrf2-mediated genes expressing anti-oxidative stress. Such phytochemicals include indoles, such as 3,3′-diindolylmethane (DIM) and indole-3-carbinol (I3C), and isothiocyanates, such as phenethyl isothiocyanate (PEITC) and sulforaphane (SFN).

The present invention provides methods and compositions for treating cancer in patients carrying IDH1 mutations using combinations of inhibitors of mutant IDH1 enzymes and DNA demethylating agents.

The present invention describes compositions, including pharmaceutical compositions, comprising a PD-1 axis binding antagonist, a CTLA4 antagonist, or a DNA demethylating agent and a benzamide compound and methods for use thereof, for example in the treatment of cancer. In some implementations, the methods for use including methods of treating conditions where enhanced immunogenicity is desired such as increasing tumor immunogenicity for the treatment of cancer.

The present invention relates to an improved process for O-demethylating methoxy substituted morphinan-6-one derivatives using AlCl3 as a demethylating agent in a reaction-inert solvent having a water content ranging from 0.1% wt to 0.8% wt. 10.
