| 摘要 |
<p>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, for manufacturing a prophylactic or therapeutic agent for an ischemic disease. According to the present invention, the apoptosis can be efficiently suppressed, so that its application as a therapeutic agent for AIDS, neurodegenerative disorders, osteomyelodysplasia, ischemic diseases, infectious multiple organ failure, fulminant hepatitis, diabetes and the like can be expected.</p> |
