Abstract. Sorghum bicolor L. Moench is widely grown all over the world for food and feed. The effects of sorghum extracts on general inflammation have been previously studied, but its anti-vascular inflammatory effects are unknown. Therefore, this study investigated the anti-vascular inflammation effects of sorghum extract (SBE) and fermented extract of sorghum (fSBE) on human aortic smooth muscle cells (HASMCs). After the cytotoxicity test of the sorghum extract, a series of experiments were conducted. The inhibition effects of SBE and fSBE on the inflammatory response and adhesion molecule expression were measured using treatment with tumor necrosis factor-α (TNF-α), a crucial promoter for the development of atherosclerotic lesions, on HASMCs. After TNF-α (10 ng/mL) treatment for 2 h, then SBE and fSBE (100 and 200 μg/mL) were applied for 12h. Western blotting analysis showed that the expression of vascular cell adhesion molecule-1 (VCAM-1) (2.4-fold) and cyclooxygenase-2 (COX-2) (6.7-fold) decreased, and heme oxygenase-1 (HO-1) (3.5-fold) increased compared to the TNF-α control when treated with 200 μg/mL fSBE (P<0.05). In addition, the fSBE significantly increased the expression of HO-1 and significantly decreased the expression of VCAM-1 and COX-2 compared to the TNF-α control in mRNA level (P<0.05). These reasons of results might be due to the increased concentrations of procyanidin B1 (about 6-fold) and C1 (about 30-fold) produced through fermentation with Aspergillus oryzae NK for 48 h, at 37 °C. Overall, the results demonstrated that fSBE enhanced the inhibition of the inflammatory response and adherent molecule expression in HASMCs.

The migration and matrix metalloproteinase (MMP) activation of vascular smooth muscle cells may play key roles in the development of atherosclerosis. Carnosic acid (CA) is a phenolic compound found in herbs, including rosemary and sage. Previous studies indicated that CA possesses antioxidant activity in vitro. In this study, we investigated the effects of CA on TNF-α-induced cell migration, the formation of intracellular reactive oxygen species, the translocation of NF-κB and the activation and expression of MMP-9 in human aortic smooth muscle cells (HASMC). The Matrigel migration assay showed that CA (10 and 20 μmol/l) effectively inhibited TNF-α-induced migration of HASMC as compared with the control group. To explain this inhibitory effect, MMP-9 was assayed by gelatin zymography and Western blot. The results indicated that CA inhibited MMP-9 activity and expression. Furthermore, the production of reactive oxygen species and the nuclear translocation of NF-κB p50 and p65 induced by TNF-α were dose-dependently suppressed by CA pretreament. These results indicate that CA has anti-inflammatory properties and may prevent the migration of HASMC by suppressing MMP-9 expression through down-regulation of NF-κB.
