Schematic representation of the role of JTE-013 in pulmonary fibrosis. JTE-013 or S1PR2 knockdown inhibited the binding of S1P and S1PR2 to regulate the RHOA/YAP pathway. This further affected the downstream CTGF/CYR61 expression and mitochondrial dynamics, promoted mitochondrial fusion and the phenotypic transition of MFN, inhibited mitochondrial fission, down-regulated the phosphorylation level of Fis1 and Drp1, and reduced the production of mitochondrial ROS and ROS, thereby alleviating pulmonary fibrosis.

The cell function analysis are all chemically synthesized interference lncRNA and eukaryotic plasmid-mediated lncRNA transient transfection. These have limited gene silencing and overexpression efficiency and show that the correlation between LNC01508 and OC cisplatin resistance is not highly significant. Furthermore, the effect of eukaryotic plasmid-mediated lncRNA overexpression is better than the chemical synthesis of lncRNA. This suggests a stable transfection in vitro to provide knockout and overexpression effects. (A) qPCR detects a lower LINC01508 expression, and the CCK-8 assay measures the cell viability.
