  • Patent number: 7229773
    Abstract: To provide a screening method for an apoptosis-suppressing substance or an apoptosis-promoting substance, the application of which substances to pharmaceuticals or diagnostic drugs are expected, also to provide an apoptosis-suppressing substance or an apoptosis-promoting substance, since Bcl-2 family having apoptosis-suppressing or -promoting activities is deeply involved in many diseases. To attain the above object, VDAC-liposomes, an indicator substance such as fluorescent-labeled cytochrome c or isotope-labeled sucrose etc. capable of passing through VDAC (voltage-dependent anion channel), and a subject substance are incubated, and then concentration changes in the indicator substance, inside and outside the VDAC-liposomes before and after the incubation, are detected in order to estimate presence or absence of the apoptosis-suppressing activity or -promoting activity of the subject substance.

  • Patent number: 7011951
    Abstract: A polypeptide possessing an action of causing chromatin condensation; a sense nucleic acid encoding the polypeptide; an antisense nucleic acid thereof, a probe or primer capable of specifically binding to the nucleic acid; an antibody or a fragment thereof against the polypeptide; an agent for controlling apoptosis, comprising the nucleic acid, the polypeptide, or the antibody or a fragment thereof; a screening method for a substance for controlling chromatin condensation, comprising evaluating an activity of causing chromatin condensation exhibited by the polypeptide; and a substance for controlling chromatin condensation. The present invention is useful for screening a substance controlling apoptosis, its use for controlling apoptosis and its applications to various diseases accompanying apoptosis.

  • Publication number: 20030152946
    Abstract: A BH4 fusion polypeptide comprising an amino acid sequence of a polypeptide capable of exhibiting uptake action into a cell or a derivative sequence thereof; and an amino acid sequence selected from the group consisting of (A) an amino acid sequence comprising at least the sequence of BH4 domain (SEQ ID NO: 1) of anti-apoptotic Bcl-2 family protein, (B) an amino acid sequence having substitution, deletion or insertion of at least one amino acid residue in the amino acid sequence of SEQ ID NO: 1, and (C) an amino acid sequence having at least 50% sequence identity to the amino acid sequence of SEQ ID NO: 1, wherein the BH4 fusion polypeptide is capable of inhibiting apoptosis; an apoptosis-inhibitor comprising the BH4 fusion polypeptide mentioned above; a method for treating an ischemic disease, characterized by administering the apoptosis-inhibitor mentioned above to a patient with the ischemic disease to inhibit apoptosis, thereby treating the ischemic disease; and use of the BH4 polypeptide mentioned above,

  • Patent number: 5595869
    Abstract: The sequence of the protein coding regions of the bcl-2 gene are provided as well as bacterial clones which produce the proteins. Assays are provided for detecting a class of B-cell neoplasms associated with a chromosome translocation between chromosomes 14 and 18. This translocation is involved in the majority of cases of human follicular lymphomas. One assay employs an antibody which is immunoreactive with a human protein which is over-expressed due to the chromosome translocation. Another assay involves measurement of the amount of mRNA which hybridizes to the gene proximal to the translocation break-point.
