The invention provides methods of diagnosing and treating heart diseases and conditions, methods for identifying compounds that can be used to treat or to prevent such diseases and conditions, and methods of using these compounds to treat or to prevent such diseases and conditions. Also provided in the invention are animal model systems that can be used in screening methods.

The invention provides a method for assaying for troponin I in a sample such as serum, the method comprising a determination of the troponin I concentration in a sample using a standard preparation that comprises a complete native troponin complex. One exemplary assay for troponin I concentration according to the invention is an immunoassay. Further contemplated in the method is a step comprising contacting the sample with a Ca²⁺-binding agent. Another aspect of the invention is the standard preparation comprising a complete native troponin complex. Yet another aspect of the invention is a kit for use in the assay method comprising the standard preparation, a detectable label, and a troponin I binding partner, such as an anti-troponin I antibody. All aspects of the invention are usefully practiced using human materials, such as a human troponin complex, and/or human sources for samples.

A non-human animal model is provided, particularly a mouse model for movement hyperactivity, excitoxicity disorders (e.g. myoclonic cramping) and neurodegeneration, in which modified cytoplasmic dynein heavy chain1 is expressed. Modified human and mouse cytoplasmic dynein heavy chain1 proteins and nucleic adds are also provided, including the corresponding recombinant proteins. The invention further provides uses for the non-human animal model and the modified cytoplasmic dynein heavy chain1 proteins and nucleic acids, in particular for the diagnosis and treatment of medical conditions associated with over-expression of cytoplasmic dynein heavy chain1.

The present invention provides compositions and methods for targeting an extracellular matrix derived (EMD) peptide predominantly to an injured tissue, as opposed to an uninjured tissue in vivo. The targeted EMD peptide facilitates the repair and/or regeneration of the injured tissue by providing a surface for cells to attach and grow, thereby facilitating the repair and/or regeneration of the injured tissue.

The invention provides a DNA element for high-throughput in vitro protein synthesis, and specifically discloses a novel DNA element capable of greatly enhancing protein translation efficiency. According to the present invention, with the application of the DNA element in a yeast in-vitro protein synthesis system, the relative light unit value of the activity of the synthesized luciferase is enhanced by about 22.3 times compared to the DNA element containing only the omega sequence.

Disclosed herein are compositions and methods for repairing cell membranes. In addition, the invention relates to therapeutic compositions comprising nucleotides and/or polypeptides of the invention in combination with a pharmaceutically acceptable carrier, wherein the composition facilitates the repair of cell membranes. Moreover, the invention relates to the treatment and/or prevention of pathological conditions associated with cell membrane damage.

A cardiac troponin I ultra-sensitive detection reagent kit, a preparation method, and a detection method. The reagent kit comprises at least one first anti-cardiac troponin I antibody marked with a trace marker and at least one second anti-cardiac troponin I antibody coated on magnetic microspheres, the first anti-cardiac troponin I antibody and cardiac troponin I binding site being different from the second anti-cardiac troponin I antibody and cardiac troponin I binding site. The reagent kit may further comprise a diluent capable of significantly reducing non-specific binding in a detection process, so as to further increase the detection accuracy and sensitivity. The method using the reagent kit to detect cardiac troponin I sensitively and accurately detects the amount of cardiac troponin I in a sample, and provides more timely and reliable information for the early diagnosis and treatment of AMI.

Disclosed are materials and methods for treating diseases of the mammalian eye, and in particular, Usher syndrome 1B (USH1B). The invention provides AAV-based, dual-vector systems that facilitate the expression of full-length proteins whose coding sequences exceed that of the polynucleotide packaging capacity of an individual AAV vector. In one embodiment, vector systems are provided that include i) a first AAV vector polynucleotide that includes an inverted terminal repeat at each end of the polynucleotide and a suitable promoter followed by a partial coding sequence that encodes an N-terminal portion of a full-length polypeptide; and ii) a second AAV vector polynucleotide that includes an inverted terminal repeat at each end of the polynucleotide and a partial coding sequence that encodes a C-terminal portion of a full-length polypeptide, optionally followed by a polyadenylation (pA) signal sequence. In another embodiment, the vector system includes i) a first AAV vector polynucleotide comprising an inverted terminal repeat at each end, a suitable promoter followed by a partial coding sequence that encodes an N-terminal portion of a full-length polypeptide followed by a splice donor site and intron and ii) a second AAV vector polynucleotide comprising an inverted terminal repeat at each end, followed by an intron and a splice-acceptor site for the intron, followed by a partial coding sequence that encodes a C-terminal portion of a full-length polypeptide, optionally followed by a polyadenylation (pA) signal sequence. The coding sequence or the intron sequence in the first and second AAV vectors preferably includes a sequence region that overlaps.

A water soluble peptide composition derived from animal muscle tissue proteins is provided. The peptide composition contains less than about 1 weight percent fats and oils based upon the weight of the peptide composition and less than about 2 weight percent ash based on the weight of the peptide composition.

The invention pertains to methods for detecting the presence or absence of a mutation associated with hypertrophic cardiomyopathy (HC). The methods include providing DNA which encodes a cardiac myosin binding protein and detecting the presence or absence of a mutation in the amplified product which is associated with HC. The invention further pertains to methods for diagnosing HC in a subject. These methods typically include obtaining a sample of DNA which encodes a cardiac myosin binding protein from a subject being tested for FHC and diagnosing the subject for FHC by detecting the presence or absence of a mutation in the sarcomeric thin filament protein which causes FHC as an indication of the disease. Other aspects of the invention include kits useful for diagnosing HC and methods for treating HC.

The subject invention relates to antibodies to troponin I as well as methods of use thereof. In particular, such antibodies may be used to detect Troponin I in a patient and may also be used in the diagnosis of, for example, a myocardial infarction or acute coronary syndrome.
