Figure 6 : Effects of (a) LB extract and (b) taurine on protein expression of claudin-1 in high glucose-treated ARPE-19 cells. The relative levels of protein for claudin-1 was assessed by the immunoblotting method, and normalised to α-tubulin. Levels in control were arbitrarily assigned a value of 1.0. Values are means ± SEM (n=6). #P<0.001 versus Control, *P<0.05, **P<0.01 versus high glucose (HG).
