Title:
改変アデノウイルス及びこれを含む医薬
Document Type and Number:
Japanese Patent JP7406263
Kind Code:
B2
Abstract:
[Problem] The purpose of the present invention is to provide a modified adenovirus having a cytocidal activity on a target cell and high safety. [Solution] The present invention pertains to: a modified adenovirus which comprises an E1A gene, an enhancer sequence having a function of enhancing the expression of the E1A gene, and an AU-rich element introduced into the 3'-untranslated region of a viral gene, which is essentially required for the self-propagation thereof, or a position adjacent to the 3'-untranslated region, or a modified adenovirus which comprises an E1A gene and an enhancer sequence having a function of enhancing the expression of the E1A gene and cannot express normal E4orf6 protein, wherein the distance between the 5'-terminus of the E1A gene and the terminus of the enhancer sequence is 1500-4500 bp; and a medicine comprising the same.
