What is Tanshinone IIA from Salvia miltiorrhiza BUNGE inhibits human aortic smooth muscle cell migration and MMP-9 activity through AKT signaling pathway about?
## Abstract Smooth muscle cell (SMC) migration plays an important role in normal angiogenesis and is relevant to disease‐related vascular remodeling in conditions such as brain arteriovenous malformations, pulmonary hypertension, arteriosclerosis, and restenosis after angioplasty. In this present study, we showed that tanshinone IIA, the major lipid‐soluble pharmacological constituent of __Salvia miltiorrhiza__ BUNGE, inhibits human aortic smooth muscle cell (HASMC) migration and MMP‐9 activity. Tanshinone IIA significantly inhibited IκBα phosphorylation and p65 nuclear translocation through inhibition of AKT phosphorylation. Tanshinone IIA inhibited TNF‐α‐induced ERK and c‐jun phosphorylation, but not other MAPKs such as JNK and p38. Tanshinone IIA also inhibited NF‐κB and AP‐1 DNA‐binding. Moreover, tanshinone IIA inhibited the migration of TNF‐α‐induced HASMCs. Our results provide evidence that tanshinone IIA has multiple effects in the inhibition of HASMC migration and may offer a therapeutic approach to block HASMC migration. J. Cell.
