The epithelial-mesenchymal transition (EMT) is important in organ fibrosis. We hypothesized that growth arrest-specific protein 6 (Gas6) and its underlying mechanisms play roles in the prevention of EMT in alveolar epithelial cells (ECs). In this study, to determine whether Gas6

1. NS-398 (N-[2-cyclohexyloxy-4-nitrophenyl] methanesulfonamide) is a new non-steroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic effects. 2. The anti-inflammatory potency of NS-398 in rat carrageenin-induced edema was as potent as that of indomethacin and 8 times more potent than diclofenac.

We tested the hypothesis that glucose-induced hyperosmolarity, occurring in diabetic hyperglycemia, promotes retinal angiogenesis, and that interference with osmolarity signaling ameliorates excessive angiogenesis and retinopathy in vitro and in vivo. We incubated human aortic (HAECs) and dermal microvascular endothelial cells
