The present invention relates to a
nucleic acid sequence, comprising or coding for a
coding region, encoding at least one
peptide or
protein comprising a
therapeutic protein or a fragment, variant or derivative thereof, at least one
histone stem-loop and a poly(A) sequence or a
polyadenylation signal. Furthermore the present invention provides the use of the
nucleic acid for increasing the expression of said encoded
peptide or
protein, particularly for the use in
gene therapy. It also discloses its use for the preparation of a pharmaceutical composition, e.g. for use in
gene therapy, particularly in the treatment of diseases which are in need of a treatment with a therapeutic
peptide or
protein, preferably as defined herein. The present invention further describes a method for increasing the expression of
a peptide or protein comprising a
therapeutic protein or a fragment, variant or derivative thereof, using the
nucleic acid comprising or coding for a
histone stem-loop and a poly(A) sequence or a
polyadenylation signal.
