| Popis: | Antisense inhibition of gene expression during Xenopus development was obtained by injecting, into the zygote, an expression vector carrying the adenovirus VAI gene read by RNA polymerase III. This vector yields high levels of antisense RNA in most embryonic cells between mid-blastula transition and tailbud stage. As a target we chose the Xenopus homeobox gene Xhox1A. A 26 bp long oligonucleotide, including the initiation codon of this gene, was inserted in opposite polarity into the vector. Antisense treatment reduces Xhox1A mRNA in embryos up to stage 22 and Xhox1A protein expression up to stage 30. Half of the antisense-treated embryos develop a characteristic phenotype with disorganized somites in the anterior trunk and delayed development of the intestinal tract. |
