Abstract:
The present invention relates to the roles played by the SUV420H1 and SUV420H2 genes in carcinogenesis and features a method for treating or preventing cancer by administering a double-stranded molecule against the SUV420H1 or SUV420H2 gene or a composition or vector containing such a double-stranded molecule. The present invention also features methods and kits for detecting or diagnosing cancer in a subject, including detecting an expression level of the SUV420H1 or SUV420H2 gene. The present invention further features methods and kits for assessing or determining the prognosis of a subject with cancer, including detecting the expression level of an SUV420H2 gene. Also, disclosed are methods of screening for candidate substances for treating or preventing cancer or inhibiting cancer cell growth, using as an index their effect on the expression or activity of SUV420H1 or SUV420H2.
Abstract:
Provided herein are H1.0K180me2 antibodies, H1.0K180me2 proteins, and H1.0K180me2 peptides and methods of use for diagnostics and therapeutics. These H1.0K180me2 antibodies, H1.0K180me2 proteins, and H1.0K180me2 peptides may be used in the treatment of methylated H1.0-related diseases or conditions in an individual. These H1.0K180me2 antibodies, H1.0K180me2 proteins, and H1.0K180me2 peptides may also be used for the detection and quantification of a histone H1.0 protein or fragment thereof, comprising a dimethylated lysine at lysine residue 180 (H1.0K180me2); such compositions and methods are useful for detecting replicative senescence, DNA damage, genotoxic stress, radiation exposure, Alzheimer's disease, are useful for monitoring therapeutic regimens, patient stratification, drug screening, and may serve as a marker of biological aging in a system.
Abstract:
A product comprising two or more artificial transcription repressors (ATRs), or polynucleotides encoding therefor, selected from groups (a), (b), (c) or (d): (a) an ATR comprising a DNA-binding domain operably linked to a KRAB domain or homologue thereof; (b) an ATR comprising a DNA-binding domain operably linked to a DNMT3A, DNMT3B or DNMT1 domain or homologue thereof; (c) an ATR comprising a DNA-binding domain operably linked to a DNMT3L domain or homologue thereof; and (d) an ATR comprising a DNA-binding domain operably linked to a SETDB1 domain or homologue thereof, wherein at least two of the ATRs are selected from different groups (a), (b), (c) or (d).
Abstract:
The present invention provides methods and compostions to improve the efficiency of somatic cell nuclear transfer (SCNT) and the consequent production of nuclear transfer ESC (ntESC) and transgenic cells and/or non-human animals. 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 donor somatic cells prevents efficient somatic cell nuclear reprogramming or SCNT. The present invention provide methods and compositions to decrease H3K9me3 in methods to improve efficacy of SCNT 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:
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:
A method for promoting the reprogramming of a non-cardiomyocytic cell or tissue into cardiomyocytic cell or tissue comprising is carried out by contacting a non- cardiomyocytic cell or tissue with a modulator of histone methyltransferase activity or expression.
Abstract:
The present disclosure relates to recombinant methyltransferases that epigenetically silence gene expression and to methods of using such proteins for reducing the expression of genes in plants.
