Objective:To study the effect of chrysophanol from pinellia on tumor necrosis factor-α (TNF-α)-induced human cerebral microvascular endothelial cells (HBMEC). Method:HBMECs were cultured in vitro
and modeled with TNF-α. The cells were divided into normal group
model group
chrysophanol group and edaravone group. TNF-α
interleukin-6 (IL-6) and IL-8 mRNA expressions were detected by RT-PCR. TNF-α
IL-6
IL-8
p-JNK and p-ERK were detected by enzyme-linked immunosorbent assay (ELISA). Protein expressions of p-JNK
total JNK
p-ERK and total ERK were detected by Western blot. Result:At the concentration of 256 μmol·L-1
chrysophanol significantly inhibited HBMEC cells (P<0.01). Compared with the model group
chrysophanol had a significant effect on the growth of model cells at concentrations between 64 μmol·L-1 and 128 μmol·L-1 (P<0.05). Expressions of TNF-α
IL-6
IL-6
IL-8
p-JNK and p-ERK in chrysophanol group were significantly decreased (P<0.05). Expressions of p\|JNK/JNK and p\|ERK/ERK in chrysophanol group were significantly decreased (P<0.05). Conclusion:Chrysophanol has an effect in inhibiting TNF-α-induced HBMEC damage
and may reduce the expressions of TNF-α
IL-6 and IL-8 by down-regulating ERK/JNK signaling pathway.
