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 recptor (PPAR)-.delta. 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.

Cette invention concerne des compositions médicamenteuses permettant d'induire l'apoptose de cellules, qui renferment un gène de la prostacyline synthase comme principe actif ; des compositions médicamenteuses pour la thérapie génique du cancer qui renferment comme principe actif les compositions médicamenteuses précitées permettant d'induire l'apoptose de cellules ; et une méthode de dépistage d'un agent induisant l'apoptose de cellules, caractérisé en ce que l'activation du récepteur .delta. activé par un proliférateur du peroxysome est déterminé en présence d'une substance d'essai. L'emploi des compositions médicamenteuses susmentionnées permet de traiter des maladies pour lesquelles déclenchement de l'apoptose permet d'obtenir des effets thérapeutiques. Dans le cadre d'une thérapie génique, lesdites compositions induisent la mort cellulaire des cellules cancéreuses. La méthode susmentionnée permet de rechercher systématiquement un médicament capable d'induire l'apoptose.
