The invention relates to an artificial
nucleic acid molecule comprising at least one 5′ UTR element which is derived from a TOP
gene, at least one
open reading frame, and preferably at least one
histone stem-loop. Optionally the artificial
nucleic acid molecule may further comprise, e.g. a poly(A)sequence, a poyladenylation
signal, and / or a 3′ UTR. The invention further relates to the use of such an artificial
nucleic acid molecule in
gene therapy and / or
genetic vaccination.
