Inhibitory Activity of (+)-Usnic Acid against Non-Small Cell Lung Cancer Cell Motility
Fig 7
(+)-Usnic acid shows additive inhibitory activity with cetuximab.
(A-B) Invasion assay of A549 cells treated with 5 μM of (+)-usnic acid and/or various concentration of cetuximab (A), and quantitative analysis of invaded cell numbers in each group (B). Representative images are shown from three independent experiments, n = 3. Data represent mean ± S.E.M. (standard error of the mean). *p<0.05; **p<0.01; ***p<0.001; NS, no significant difference between indicated group.
