In vitro study showed that treating VSMCs with TNF-α together with DOX remarkably inhibited the expressions and activities of MMPs (MMP-2 and MMP-9), significantly suppressed the activation of protein kinase B (AKT) signaling pathway and mitogen-activated protein kinases (MAPKs) signal proteins, including extracellular signal-regulated kinase (ERK), c-Jun amino-terminal kinases (JNK) and p38, and downregulated mRNA levels of interleukin-6 (IL-6) and monocyte chemotactic protein 1 (MCP-1), and significantly upregulated mRNA levels of transforming growth factor beta (TGF-β), heme oxygenase 1 (HO-1) and superoxide dismutase 1 (SOD-1), indicating that DOX inhibits activities of MMPs through reducing oxidative stress, suppressing MAPKs and AKT signaling pathways and ameliorating inflammation in VSMCs, and therefore, exerts preventive as well as therapeutic effects on AAA.
