LPS accelaerates SW480 colon cancer cell adhesion via Nox regulation of PI3K/Akt signalling.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
(a,b) LPS treatment resulted in a significant increase in SW480 cell adhesion to collagen I after 1 hour. This was inhibited using a recognised Nox inhibitor, DPI (2 µM), and a PI3K inhibitor, LY294002(5 µM). (c) Nox1 siRNA abrogates LPS induced ROS and Nox1 knockdown is confirmed by Western Blotting. (d) The increase in SW480 colon cancer cell adhesion was completely inhibited by Nox1 siRNA. * P<0.05. These data are representative of 3 independent experiments.
