- W4293101989 abstract "Background: Filamentous plant virus-derived nanoparticles are biodegradable and noninfectious to humans. Their structure is also amenable to chemical modifications. They constitute an appealing material for biomedical applications including imaging and drug delivery. We had previously used turnip mosaic virus-derived nanoparticles (TuMV-NPs) to increase antibody-sensing in vivo, to prevent biofilm formation and to build biological nanoscaffolds. Materials & methods: We analyzed TuMV-NP biodistribution and tumor homing using in vivo imaging. We studied in vitro the interaction with human cancer cell lines and the antiproliferative effect of epigallocatechin gallate-functionalized TuMV-NPs. Results & conclusion: TuMV-NPs are efficiently internalized by human cells and show good tumor homing. The antiproliferative effect of epigallocatechin gallate-TuMV-NPs suggests that they could offer a potential anticancer therapy.Cancer is the second leading cause of death worldwide, just behind cardiovascular disease. It accounts for nearly 10 million deaths annually, and new strategies to improve early detection and drug delivery are urgently needed. Nanoparticles are small structures within the nanometer range (1 billionth of a meter) that can be used to deliver either an imaging probe (tracer) to allow the detection of a tumor or drugs to kill tumor cells. There are many types of nanoparticles; those based on plant viruses are especially appealing for biomedical purposes because they are biodegradable and noninfectious to humans. Also, their physicochemical properties, such as symmetry, uniformity and loading capacity, make them excellent nanocarriers. We report here for the first time the ability of nanoparticles derived from the turnip mosaic virus (TuMV), a well-known virus naturally infecting cruciferous plants (e.g., broccoli, turnip, radish, cabbage) but not humans, to deliver a fluorescent imaging probe that allows tumor detection in vivo. Moreover, TuMV nanoparticles were used to deliver a natural chemotherapeutic agent of plant origin to different types of tumor cells (lung, colorectal, breast, and head and neck), showing increased antiproliferative capacity compared to the nonvehiculized drug." @default.
