The present invention relates to a method for inducing production of vascular endothelial growth factor (VEGF). The method includes administering, to an individual, a composition including adeno-associated virus (AAV) carrying a hPGIS gene coding for human prostacyclin synthase (hPGIS) which synthesizes prostaglandin I(PGI).

Method for inducing production of vascular endothelial growth factor

Drug compositions of angiogenesis therapy contain gene coding for human prostacyclin synthase (hPGIS) synthesizing prostaglandin Iwith activities of vasodialation and/or anti-platelet aggregation; drug compositions contain adeno-associated virus (AAV) inserted with gene for angiogenesis factors. The administration of the drug compositions into the aimed treatment region results in transfer of AAV type 1-hPGIS to skeletal muscles and induces a notable expression of human PGIS gene in skeletal muscles. The PGIis produced by mediation of the gene expression in the muscle cells, secreted, induces vessel-protective, neovascularization and anti-platelet aggregation actions, which lead to an improvement in vascular ischemia.

Drug composition for angiogenesis therapy

The present invention provides: (1) pharmaceutical compositions for angiogenic therapy which contain, as the active ingredients, at least one substance selected from substances having vasodilating effect and/or platelet aggregation inhibitory effect, and substances producing them; and a gene encoding an angiogenesis factor; (2) agents for potentiating the angiogenic effect of a gene encoding an angiogenesis factor that contain, as the active ingredient, at least one substance selected from substances having vasodilating effect and/or platelet aggregation inhibitory effect and substances producing them; (3) an angiogenic agent which contains a prostacyclin synthase gene as the active ingredient; (4) pharmaceutical compositions for angiogenic therapy which contain ets-1 gene and another gene encoding an angiogenesis factor as the active ingredients; (4) an agent which contain ets 1 gene as the active ingredient for potentiating the angiogenic effect of another gene encoding an angiogenesis factor; and (5) an angiogenic agent which contains ets-1 gene as the active ingredient.

Compositions and methods for angiogenic therapy utilizing genes encoding ets-1

The present invention relates to: pharmaceutical compositions for inducing apoptosis in cells, the pharmaceutical compositions comprising a prostacyclin synthase gene as an active ingredient; pharmaceutical compositions for gene therapy of cancer, the pharmaceutical compositions comprising the above pharmaceutical compositions for inducing apoptosis as an active ingredient; and a screening method for an agent that induces apoptosis in a cell, the method comprising determining the activation of peroxisome proliferator-activated receptor (PPAR)-&#x3b4; in the presence of a test substance. The pharmaceutical composition of the present invention for inducing apoptosis enables treatment of diseases on which induction of apoptosis has a therapeutic effect. In addition, the pharmaceutical composition of the present invention for gene therapy can lead cancer cells to cell death. Furthermore, the screening method of the present invention can be used conveniently to screen for agents capable of inducing apoptosis.

Medicinal compositions containing prostacylin synthase gene

The present invention clarifies the primary structure of human-originated PGIS and the nucleotide sequence encoding same. The PGIS and its DNA are useful as reagents for the development of therapeutic agents for the cardiovascular diseases induced by the production imbalance between PGIand TXA, and as diagnostics for determining the in vivo tissue expression level and distribution of PGIS or mRNA thereof. Moreover, they can be used as therapeutic agents for cardiovascular diseases, which introduce PGIS and the like into human or other animals in a lesion-specific manner. The production method of the present invention is useful for the easy and efficient mass production of the human-originated PGIS. The antibody of the present invention is useful for the purification of the human-originated PGIS and immunohistochemical analysis of the cause of a disease.
