abstract = {Magnetically responsive microbubbles (MagMBs), consisting
of an oxygen gas core and a phospholipid coating
functionalised with Rose Bengal (RB) and/or 5-fluorouracil
(5-FU), were assessed as a delivery vehicle for the targeted
treatment of pancreatic cancer using combined antimetabolite
and sonodynamic therapy (SDT). MagMBs delivering the
combined 5-FU/SDT treatment produced a reduction in cell
viability of over $50\%$ when tested against a panel of four
pancreatic cancer cell lines in vitro. Intravenous
administration of the MagMBs to mice bearing orthotopic
human xenograft BxPC-3 tumours yielded a $48.3\%$ reduction
in tumour volume relative to an untreated control group (p <
0.05) when the tumour was exposed to both external magnetic
and ultrasound fields during administration of the MagMBs.
In contrast, application of an external ultrasound field
alone resulted in a $27\%$ reduction in tumour volume. In
addition, activated caspase and BAX protein levels were both
observed to be significantly elevated in tumours harvested
from animals treated with the MagMBs in the presence of
magnetic and ultrasonic fields when compared to expression
of those proteins in tumours from either the control or
ultrasound field only groups (p < 0.05). These results
suggest MagMBs have considerable potential as a platform to
enable the targeted delivery of combined
sonodynamic/antimetabolite therapy in pancreatic cancer.},
