Abstract

The embodiments of the present disclosure relate to one or more compositions or methods that upregulate the production of one or more sequences of micro interfering ribonucleic acid (miRNA). The sequences of miRNA may be complimentary to a sequence of target messenger RNA (mRNA) that encodes for translation of a target biomolecule, such as ETS2. The miRNA can cause the target mRNA to be degraded or inactivated, thereby causing a decrease in bioavailability of the target biomolecule because it is degraded or inactivated by the miRNA. Decreasing the bioavailability of the target biomolecule within a subject that is administered the one or more compositions may address the afflictions experienced by the subject due to overexpression of the target biomolecule.

Claims (6)

1. A composition that comprises a recombinant plasmid (RP) with a sequence of nucleotides, wherein the sequence of nucleotides is SEQ ID NO: 2.

2. The composition of claim 1 , wherein the sequence of nucleotides is configured to be delivered to a target cell that over-expressed or mis-expressed ETS2, wherein the sequence of nucleotides is encased in a protein coat, a lipid vesicle, or any combination thereof.

3. The composition of claim 1 , wherein the sequence of nucleotides is configured to be delivered to a target cell that over-expressed or mis-expressed ETS2, wherein the sequence of nucleotides is encased in a viral vector.

4. The composition of claim 3 , wherein the viral vector is one of a double stranded DNA virus, a single stranded DNA virus, a single stranded RNA virus, or a double stranded RNA virus.

5. The composition of claim 3 , wherein the viral vector is an adeno-associated virus.

6. A composition that comprises a recombinant protein (RP) with a sequence of nucleotides, wherein the sequence of nucleotides is SEQ ID NO. 3.
