Abstract:
The present invention features a method for determining the methyltransferase activity of a polypeptide and screening for modulators of methyltransferase activity, more particularly for modulators of the methylation of retinoblastoma by SMYD3. The invention further provides a method or pharmaceutical composition for prevention or treating of colorectal cancer, hepatocellular carcinoma, bladder cancer and/or breast cancer using a modulator so identified. N-terminal truncated forms of SMYD3 (alias ZNFN3A1) have higher methylating activity. Lys 824 is a preferred methylation site on the RB1 protein for SMYD3.
Abstract:
Objective methods for detecting or diagnosing cancer, or determining a predisposition for developing cancer, particularly lung cancer, cervical cancer, bladder cancer, esophageal cancer, osteosarcoma, prostate cancer and soft tissue tumor, are described herein. In one embodiment, the diagnostic method involves determining an expression level of the SUV39H2 gene. The present invention further provides methods of screening for candidate substances useful in the treatment and/or prevention of an SUV39H2-associated cancer, such as lung cancer, cervical cancer, bladder cancer, esophageal cancer, osteosarcoma, prostate cancer and soft tissue tumor. The present invention further provides methods of inhibiting the cell growth and thereby treating or alleviating symptoms of an SUV39H2 associated cancer. The present invention also features double-stranded molecules against the SUV39H2 gene and vectors encoding thereof as well as compositions containing such components and their utility in connection with the treatment and prevention of an SUV39H2-associated cancer.
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:
The invention relates to the use of the amplification of SETDB1 gene in lung cancer patients as predictive marker for the determination of the response to a SETDB1 antagonist, particularly to a SETDB1 -specific RNAi or to mithramycin. The invention relates to methods of treatment, methods for predicting the clinical response to a SETDB1 antagonist and methods for selecting a lung cancer patient for being treated with a SETDB1 antagonist based on the detection of SETDB1 gene amplification.
Abstract:
This invention relates to long non-coding RNAs (IncRNAs), libraries of those ncRNAs that bind chromatin modifiers, such as Polycomb Repressive Complex 2, inhibitory nucleic acids and methods and compositions for targeting IncRNAs. d

Abstract:
The present invention provides a reconstituted complex including EED, EZH2 and SUZ12 wherein the reconstituted complex has histone methyltransferase (HMTase) activity for lysine 27 of histone H3 (H3-K27). The reconstituted complex may further include RbAp48, AEBP2 or both. Also disclosed are methods of producing the reconstituted complex, methods of identifying compounds that inhibit the HTMase activity of the reconstituted complex and methods of identifying candidate compounds for treating cancer. Reagents and kits including the reconstituted complex are further provided.
