Methods and compositions for staining based upon nucleic acid sequence that employ nucleic acid probes are provided. Said methods produce staining patterns that can be tailored for specific cytogenetic analyses. Said probes are appropriate for in situ hybridization and stain both interphase and metaphase chromosomal material with reliable signals. The nucleic acid probes are typically of a complexity greater than 50 kb, the complexity depending upon the cytogenetic application. Methods and reagents are provided for the detection of genetic rearrangements. Probes and test kits are provided for use in detecting genetic rearrangements, particularly for use in tumor cytogenetics, in the detection of disease related loci, specifically cancer, such as chronic myelogenous leukemia (CML), retinoblastoma, ovarian and uterine cancers, and for biological dosimetry. Methods and reagents are described for cytogenetic research, for the differentiation of cytogenetically similar but genetically different diseases, and for many prognostic and diagnostic applications.

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.

The present invention relates to method for the treatment or prevention and of proliferative eye diseases including but not limited to: age related macular degeneration associated proliferative retinopathy, proliferative diabetic retinopathy, proliferative vitreoretinopathy, posterior capsular opacification, scaring and fibrosis after glaucoma filtration surgery, uveal melanoma, and retinoblastoma. The method comprises contacting cells in the eye by means of intra-ocular injection or infusion, with a drug that irreversibly inhibits cellular proliferation without causing extensive tissue necrosis or cytotoxicity. In a preferred embodiment the drug is bizelesin.

The present invention is directed to novel products, variants, pharmaceutically acceptable salts and prodrugs thereof, and medical use of such compounds for the treatment and/or management of sepsis, septicemia, septic shock, ocular infection, ocular inflammation, ocular angiogenesis, rheumatoid arthritis (RA), atherosclerosis, inflammatory bowel diseases (IBD), asthma, chronic obstructive pulmonary disease, fever syndromes, cachexia, psoriasis, autoimmune diseases, cardiac diseases, retinoblastoma, cancer and/or any disorder associated with inflammation, immunomodulation and microbial infection.

A method and pharmaceutical composition for the treatment of cancer using a gene delivery system, such as a viral vector delivery system, comprising a therapeutic gene such as p53 or a retinoblastoma tumor suppressor gene wherein the gene delivery system is formulated in a buffer comprising a delivery-enhancing agent such as ethanol or a detergent.

A method of diagnosing amyotrophic lateral sclerosis (ALS) in a subject in need thereof is provided. The method comprising determining in cells of the subject at least one alteration in a sequence or expression level of Cytoplasmic FMR Interacting Protein (CyFIP2; Accession AF160973) and/or Retinoblastoma Binding Protein 9 (RbBP9; Accession AF039564), wherein an altered sequence or expression of the sequence or expression level of the CyFIP2; Accession AF160973) or Retinoblastoma Binding Protein 9 (RbBP9; Accession AF039564) as compared to a control reference sample from a non-ALS subject, is indicative of ALS. The present teachings may be implemented in screening for novel anti-ALS medicaments and for treating ALS.

The purification of native RB (retinoblastoma) as a complex, including P107, P130, and a 600 kDa subunit, termed MTAF600 (microtubule associated factor 600) is described. MTAF600 binds to RB regardless of the phosphorylation status of RB, and binds to RB without disrupting the interaction between RB and E2F. It is further shown that E2F and DP proteins co-purified with MTAF600 and RB, such that hypophosphorylated RB may gain access to E2F as a complex with MTAF600. In addition, MTAF600 binds to microtubules and plays a role in active repression of E2F-responsive genes, cell cycle arrest, and genomic stability. The sequence of MTAF600 is described herein, along with its binding properties to proteins such as RB and microtubules, and its sequence homology. Further, methods and reagents for assaying the presence of MTAF600 or mutants thereof, pharmaceutical formulations, and methods for treating disease are also described.

The invention belongs to the field of treating RB (Retinoblastoma), and particularly relates to application of GSK503 in preparing a drug for treating the RB. In the drug, the final concentration of the GSK503 is greater than or equal to 1 mu M. The GSK503 is a novel EZH2 (Enhancer of Zeste Homolog 2) small-molecule inhibitor, and an applicant experimentally finds that the GSK503 is capable of remarkably inhibiting the growth of the RB, and the methylation degree of H3K27me3 in cells is reduced through inhibiting the EZH2, so that cancer suppressor genes can be in re-expression, and the effect of inhibiting the tumor growth is reached. Effective treatment concentration can be reached when the final concentration of the GSK503 reaches 1 mu M, the use effect of the drug is increased while the concentration is increased, and the growth of the RB can be remarkably inhibited.

Complimentary animal models for retinoblastoma which recapitulate conditions found in the eye of human retinoblastoma patients in an animal are provided. These models are generated by introducing an agent capable of giving rise to a retinoblastoma into the developing eye of an immunologically naive animal. In one model the agent comprises cells which are capable of giving rise to a retinoblastoma. In another model the agent comprises a vector capable of expressing an oncogene which, when expressed in a transfected cell, can give rise to a cell mass that mimics the early stages of retinoblastoma formation. These models can be used to study retinoblastoma and screen for, or characterize, inhibitory agents. These models may also be used to study the influence of genotype or engineered genes or gene deficiencies (knock-outs) on the development of retinoblastoma.
