  • Patent number: 8106009
    Abstract: A pharmaceutical composition for treating or preventing cytopathy caused by ischemia, comprising a midkine family protein as an active ingredient, and a pharmaceutical composition for treating or preventing ischemic disorders, comprising a midkine family protein as an active ingredient, are provided. Midkine is efficacious in treating or preventing ischemic disorders and cytopathy caused by ischemia and can remarkably prevent, for example, the development of cerebral infarction, a representative of ischemic brain disorders. The pharmaceutical composition of the present invention is also efficacious against, for example, cerebral ischemic disorders such as cerebrovascular-spasm following a subarachnoid hemorrhage, Alzheimer's disease, senile dementia of Alzheimer's type, and cerebrovascular senile dementia, as well as cerebral ischemia, transient cerebral ischemic disease, and head trauma, and other cerebrovascular diseases such as Parkinson's disease, Huntington's chorea, and amyotrophic regressive disorders.

  • Publication number: 20110111427
    Abstract: To provide a novel biomarker that is useful for prediction of early onset of acute kidney injury, estimation of prognosis associated with a renal function, and differentiation of acute kidney injury. Furthermore, to provide use of the novel biomarker. Midkine is used as a biomarker. The determination of a possibility of the onset of acute kidney injury, estimation of prognosis associated with a renal function or differentiation of an acute kidney injury are carried out based on the detection result of the urinary midkine.

  • Patent number: 7820160
    Abstract: The present invention provides a pharmaceutical composition for the prevention or treatment of angiostenosis, comprising a compound inhibiting the function of midkine (MK) in blood vessel tissues as an effective ingredient. The present invention is useful for the prevention or treatment of angiostenosis attributed to arteriosclerosis or restenosis after percutaneous transluminal coronary angioplasty (PTCA). As compounds inhibiting the function of MK, antisense oligonucleotides that bind to a segment of a single-stranded mRNA transcribed from the MK gene to inhibit the synthesis of MK protein in cells, antibodies against the MK protein, and such can be used.
