The inhibition of caveolae/raft-mediated endocytosis prevented actin
microfilament alignment. Confluent layer of HUVEC cells were treated with 25
μM caveolae/raft-mediated endocytosis inhibitor, Nystatin for 2 hours
prior to 2-hour PS nanoparticle exposure at 2.18 μg/mL or 0.66
μg/cm2. HUVEC after exposure to 20 nm PS NPs, actin (G),
nucleus and PS NPs (H). HUVEC pretreated with Nystatin after exposure to 20 nm
PS NPs, actin (E), nucleus and PS NPs (F). The 20 nm PS NPs-induced actin
alignment was prevented by inhibiting the caveolae/raft-dependent endocytosis
(E). Mean ± standard deviation of the sample. Date were analyzed with
one way ANOVA, * denotes significant difference between comparisons, n
= 20, p < 0.05.
