Abstract
A pepino mosaic virus (PepMV) carrier comprising a PepMV particle that has been modified to carry an imaging agent or anticancer agent is described. The PepMV carrier can be used in a method of targeting cancer cells and tissue by administering it to a subject. Cancer tissue targeted by the PepMV carrier can be imaged using an imaging agent, or treated using an anticancer agent.
Claims (9)
1. A filamentous plant virus carrier, comprising:
a pepino mosaic virus (PepMV) particle that has been modified to carry an imaging agent or anticancer agent, wherein the filamentous plant virus carrier targets cancer tissue selected from the group consisting of ovarian cancer or triple negative breast cancer (TNBC) and has increased tumor homing to triple negative breast cancer (TNBC) tumors and to ovarian cancer tumors compared to a potato virus X (PVX) carrier; and
wherein the PepMV carrier has 1.5-fold increase in tumor homing in triple negative breast cancer (TNBC) tumors and 2-fold increase in tumor homing in ovarian cancer tumors compared to a potato virus X (PVX) carrier.
2. The filamentous plant virus carrier of claim 1 , wherein the PepMV carrier has been PEGylated.
3. The filamentous plant virus carrier of claim 1 , wherein the PepMV particle comprises an imaging agent.
4. The filamentous plant virus carrier of claim 3 , wherein the imaging agent is a fluorescent molecule for fluorescent imaging.
5. The filamentous plant virus carrier of claim 4 , wherein the imaging agent is Cy5.
6. The filamentous plant virus carrier of claim 1 , wherein the PepMV particle comprises an anticancer agent.
7. The filamentous plant virus carrier of claim 6 , wherein the anticancer agent is an antitumor agent.
