    "abstract": "To compare the effects of the barrier function in human trabecular meshwork (TM) cells monolayer and the production of nitric oxide (NO) between trabecular outflow drugs, Rho-associated kinase (ROCK) inhibitors, adenosine, and statin.\nPrimary cultured TM cells were exposed to 10 or 25 \u03bcM Y-27632, 0.1 or 1 \u03bcM N6-cyclohexyladenosine (CHA), or 15 or 30 \u03bcM simvastatin for 24 hours. NO production and expression of endothelial nitric oxide synthase mRNA were measured by Griess assay and reverse transcription polymerase chain reaction, respectively. Barrier functions of the TM cell monolayer were measured by carboxyfluorescein and trans-endothelial electrical resistance. The expression of matrix metalloproteinase-2 mRNA was assessed with reverse transcription polymerase chain reaction.\nIn TM cells, treatment with each drug increased endothelial nitric oxide synthase mRNA expression. Treatment with 25 \u03bcM Y-27632 and 1.0 \u03bcM CHA increased NO production significantly (p = 0.035 and p = 0.043, respectively). Treatment with each drug increased the permeability (all p = 0.001) and decreased the trans-endothelial electron resistance of the TM cell monolayer. Treatment with 0.1 \u03bcM and 1.0 \u03bcM CHA significantly increased matrix metalloproteinase-2 mRNA expression, but simvastatin inhibited its expression.\nSince treatment with ROCK inhibitor more greatly increased NO production and permeability than did adenosine or statin, ROCK inhibitor seems to be more effective for lowering intraocular pressure.",
