Various therapeutic polynucleotides are provided along with their use to treat a variety of disease states. The chimeric polynucleotides disclosed herein comprise an OPN aptamer linked to an OPN-specific therapeutic oligonucleotide in order to deliver the OPN-specific therapeutic polynucleotide to the site of OPN expression. Thus, the specificity of OPN aptamers allows delivery of therapeutic molecules to the site of unhealthy tissue. Accordingly, the chimeric polynucleotides disclosed herein can reduce at least one symptom of a disease or unhealthy condition by delivering an OPN-specific therapeutic oligonucleotide that interferes with a disease promoting factor.
