Figure 5. Effects of arsenic on invasive activity and phosphorylation and/or expression levels of MT1-MMP and ERK 4 in HSC5 cells.

Figure 5

A), Invasive activity of HSC5 treated with 3 µM of arsenic was evaluated invasion assay. Level of invasive ability is presented as number of invading cells in a graph (left) and photographs (right). **, Significantly different (p<0.01) from the control by the Student's t-test. Phosphorylated levels of ERK (P-ERK) and protein expression levels of MT1-MMP and ERK in HSC5 cells treated with 3 µM arsenic for 24 hours are presented. TUBULIN protein expression levels are presented as an internal control.
