PG - 100534 LID - S2319-4170(22)00071-3 [pii] LID - 10.1016/j.bj.2022.04.005 [doi] LID - 100534 AB - BACKGROUND: Capmatinib (CAP) is a drug that has been used to treat non-small cell lung cancer (NSCLC) in adults. Presently, its novel effects on skeletal muscle insulin signaling, inflammation, and lipogenesis in adipocytes have been uncovered with a perspective of drug repositioning. However, the impact of CAP on LPS-mediated interaction between human umbilical vein endothelial cells (HUVECs) and THP-1 monocytes has yet to be investigated. METHODS: HUVECs and THP-1 monocytes were treated with LPS and CAP. The protein expression levels were determined using Western blotting. Target protein knockdown was conducted using small interfering (si) RNA transfection. Interactions between HUVECs and THP-1 cells were assayed using green fluorescent dye. RESULTS: This study found that CAP treatment ameliorated cell adhesion between THP-1 monocytes and HUVECs and the expression of adhesive molecules, such as intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin. Moreover, phosphorylation of inflammatory markers, such as NFkappaB and IkappaB as well as TNFalpha and monocyte chemoattractant protein-1 (MCP-1) released from HUVECs and THP-1 monocytes, was prevented by CAP treatment. Treatment with CAP augmented PPARdelta and IL-10 expression. siRNA-associated suppression of PPARdelta and IL-10 abolished the effects of CAP on cell interaction between HUVECs and THP-1 cells and inflammatory responses. Further, PPARdelta siRNA mitigated CAP-mediated induction of IL-10 expression. CONCLUSION: These findings imply that CAP improves inflamed endothelial-monocyte adhesion via a PPARdelta/IL-10-dependent pathway. The current study provides in vitro evidence for a therapeutic approach for treating atherosclerosis. CI - Copyright (c) 2022 Chang Gung University. Published by Elsevier B.V. All rights reserved.
