RT-PCR amplification of TLR4. Lipopolysaccharide (LPS) upregulated expression level of TLR4 mRNA in neonatal rat ventricular myocytes (NRVMs), whereas Ginkgo biloba leaf extract (GBE50) and caffeic acid phenethyl ester (CAPE) reduced LPS-induced increase in expression level of TLR4. 1, DNA marker; 2, control group; 3, LPS group; 4, LPS + GBE50 group; 5, LPS + CAPE group. △P<0.01 compared with control group; ▲P<0.01 compared with the LPS group.
