After 2 days of KN-93 treatment, 95% of cells are arrested in G1. G1 arrest is reversible; 1 day after KN-93 release, a peak of cells had progressed into S and G2-M. KN-93 also blocks cell growth stimulated by basic fibroblast growth factor, platelet-derived growth factor-BB, and epidermal growth factor in NIH 3T3 fibroblasts[1]. KN-93 inhibits the H+, K+-ATPase activity but strongly dissipates the proton gradient formed in the gastric membrane vesicles and reduces the volume of luminal space[2]. KN-93 (0.5 μM) prevents increased LV developed pressure during action potential prolongation and early afterdepolarizations. Ca2+-independent CaM kinase activity is increased during early afterdepolarizations and this increase is prevented by KN-93[3]. KN-93 (10 μM )significantly inhibits the activation of CaMKII/NF-κB signaling induced by elevated glucose, and subsequently decreases the expression of VEGF, iNOS and ICAM-1 in Müller cells[4].

Protocol
Cell viability is assessed by the 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT) assay. Briefly, Müller cells are seeded at a density of 10×104 cells per well in 96-well plates and cultured until sub-confluence. Next, cells are treated with curcumin for 24 h before incubation with MTT (5 mg/mL) at 37°C in 5% CO2 atmosphere for 4 h. The culture medium is then removed, and the formazan formed in the reaction is dissolved in 150 μL DMSO. The optical density of the solution is measured at 490 nm using a multifunctional microplate reader. Cell viability in each well is presented as a percentage of the control (vehicle-treated group).
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Male Sprague-Dawley rats (8 weeks of age) weighing 180-200 g are used in this study. Rats are housed in ventilated microisolator cages with free access to water and food. The rats are randomLy assigned to receive either 60 mg/kg STZ intraperitoneally or citrate buffer alone. Rats are categorized as diabetic when blood glucose levels exceeded 16.7 mM at 48 h after STZ treatment. Two weeks after the induction of diabetes, rats are divided randomLy into three subgroups: STZ-diabetic rats (n=12), STZ-treated diabetic rats administered curcumin (n=12), or STZ-diabetic rats administered KN93 (n=12) for a 12-week period. Curcumin is suspended in saline containing 0.5% carboxymethylcellulose at a concentration of 20 mg/mL and administered via oral gavage at a total dose of 100 mg/kg/day. KN93 is administered by intraperitoneal injection at 1 mg/kg/day. Control STZ-treated diabetic rats and non-diabetic controls (n=12) are gavage administered saline containing 0.5% carboxymethylcellulose on a daily basis. Body weights and blood glucose levels are measured every 2 weeks.
