Abstract
A nanoparticle includes an icosahedral-shaped plant virus particle; an RNAi construct; and one or more endolysosomal release agents, wherein the RNAi construct is noncovalently loaded within the icosahedral-shaped plant virus particle.
Claims (11)
1. A nanoparticle comprising a cowpea chlorotic mottle virus (CCMV); a siRNA; and an L17E M-lycotoxin peptide, wherein the siRNA is noncovalently loaded within the CCMV.
2. The nanoparticle of claim 1 , the siRNA comprising a siRNA targeting the forkhead box transcription factor (FOXA1) oncogene.
3. The nanoparticle of claim 1 , wherein the L17E M-lycotoxin peptide is linked to the exterior surface of the CCMV.
4. A method of treating hormone dependent breast cancer in a subject, comprising administering to the subject a therapeutically effective amount of a nanoparticle including a cowpea chlorotic mottle virus (CCMV), an siRNA targeting the forkhead box transcription factor (FOXA1) oncogene, and a L17E M-lycotoxin peptide, wherein the RNAi construct is encapsulated within the CCMV.
5. The method of claim 4 , wherein the L17E M-lycotoxin peptide is linked to the exterior surface of the CCMV plant virus nanoparticle.
6. The method of claim 4 , wherein the nanoparticle is administered to the subject systemically.
7. The method of claim 4 , further comprising administering a therapeutically effective amount of an additional anticancer agent or therapy to the subject.
8. The method of claim 7 , wherein the additional anticancer agent is selected from an antitumor agent and an anti-hormonal agent.
9. The method of claim 7 , wherein the additional anticancer therapy is selected from radiation therapy, brachytherapy and an ablation therapy.
10. A method of treating hormone dependent breast cancer in a subject, comprising administering to the subject a therapeutically effective amount of nanoparticle comprising a cowpea chlorotic mottle virus (CCMV) virus particle, an siRNA targeting the forkhead box transcription factor (FOXA1) oncogene, wherein the siRNA is encapsulated within the CCMV virus particle, and one or more endolysosomal release agents comprising a L17E M-lycotoxin peptide.
11. The nanoparticle of claim 1 , the siRNA comprising an oncogene targeted siRNA.
