In search of a unique and reliable contrast agent
targeting pancreatic adenocarcinoma, new multifunctional
nanoparticles (MnMEIO-silane-NH2-(MUC4)-mPEG NPs) were
successfully developed in this study. Mucin4-expression
levels were determined through different imaging studies
in a panel of pancreatic tumor cells (HPAC, BxPC-3, and
Panc-1) both in vitro and in vivo studies. The in vitro
T2-weighted MR imaging study in HPAC and Panc-1 tumor
cells treated with NPs showed - 89.1 5.7% and - 0.9
0.2% contrast enhancement whereas in in vivo study,
it is found to be - 81.5 4.5% versus - 19.6 5.2%
(post-injection) respectively.
