Hyaluronic Acid 29-39 tight junction protein 1 Homo sapiens 142-146 21839834-3 2011 By immunofluorescence and western blot, we observed a significant dose-dependent (0.1, 1, 5 and 10 mg/ml) increase by low molecular weight hyaluronan (40 kDa) in the expression of tight junction proteins such as ZO-1, as well as an increase in the trans-epithelial resistance.
