CA 2383321

The present invention discloses novel smooth muscle cell specific promoters and uses thereof. The promoters are suited for providing nucleic acid of interest with the capability of expressing specifically in a contractile smooth muscle cell, preferably a vascular contractile smooth muscle cell and/or a visceral contractile smooth muscle cell. One example of such a promoter is a smoothelin gene promoter. For gene therapy purposes said smoothelin gene promoter is preferably derived from a human. A promoter of the invention may be incorporated into nucleic acid delivery vehicle. The nucleic acid delivery vehicle preferably comprises a virus-like particle such as an adenovirus particle, an adeno-associated virus particle or a retrovirus particle.

La présente invention concerne de nouveaux promoteurs spécifiques des cellules musculaires lisses et leurs utilisations. Ces promoteurs permettent de conférer à un acide nucléique considéré la capacité de s'exprimer spécifiquement dans une cellule musculaire lisse contractile, de préférence une cellule musculaire lisse contractile vasculaire et/ou une cellule musculaire lisse contractile viscérale. Un exemple de ce type de promoteur est un promoteur du gène smootheline, dérivé, de préférence d'un être humain. Le promoteur selon l'invention peut être incorporé dans un vecteur d'acide nucléique. Ce vecteur d'acide nucléique comprend, de préférence, une particule du type virus, notamment une particule d'adénovirus, un particule de virus adéno-associé ou une particule de rétrovirus.
