Abstract:
The present invention provides methods and compositions to improve the efficiency of somatic cell nuclear transfer (SCNT) of human cells and the consequent production of human nuclear transfer ESC (hNT-ESCs). More specifically, the present invention relates to the discovery that trimethylation of Histone H3-Lysine 9 (H3K9me3) in reprogramming resistant regions (RRRs) in the nuclear genetic material of human donor somatic cells prevents efficient human somatic cell nuclear reprogramming or SCNT. The present invention provide methods and compositions to decrease H3K9me3 in methods to improve efficacy of hSCNT by exogenous or overexpression of the demethylase KDM4 family and/or inhibiting methylation of H3K9me3 by inhibiting the histone methyltransferases SUV39h1 and/or SUV39h2.
Abstract:
The disclosure relates to methods and compositions for reactivating a silenced FMR1 gene. In some aspects, methods described by the disclosure are useful for treating a FMR1-inactivation-associated disorder (e.g., fragile X syndrome).
Abstract:
The present invention relates to a pharmaceutical composition comprising a histone-lysine N-methyltransferase EZH2 (enhancer of zeste homolog 2) inhibitor and an enhancer of interferon-gamma receptor activity. The invention also relates to method of treating a patient having cancer, comprising administration of the pharmaceutical composition.
Abstract:
Provided herein are polypeptides containing stabilized therapeutic peptides related to enhancer of zeste homolog 2 (EZH2), histone lysine N-methyltransferase. Also provided are compositions containing these polypeptides and methods of using such peptides in the treatment of cancer that include administering to a subject one of the polypeptides.
Abstract:
The present invention relates to a composition for adjusting a pluripotent stem cell including an LIN28A methylation inhibitor and to a method for screening the LIN28A methylation inhibitor. More particularly, the present invention relates to a composition for treating cancer or adjusting a pluripotent embryonic stem cell including an inhibitor which controls the methylation of LIN28A 135th lysine which is methylated by Set7/9 and to a method for screening the inhibitor. The method of the present invention comprises the following steps: (a) making a candidate material touch a cell in which an LIN28A gene is introduced; (b) measuring the methylation level of the 135th lysine of LIN28A; and (c) selecting an inhibitor which controls the methylation of the 135th lysine of LIN28A. By means of the method of the present invention, a material which can adjust a pluripotent embryonic stem cell or a material having anticancer activities can be effectively screened. The inhibitor screened by means of the method of the present invention adjusts a pluripotent embryonic stem cell and controls the growth of a cancer cell, thereby being effective in producing an agent for treating cancer or stem cell differentiation disorders.
