Rutaecarpine Reverses the Altered Connexin Expression Pattern Induced by Oxidized Low-density Lipoprotein in Monocytes.
Journal of Cardiovascular Pharmacology 2016 June
Adhesion of monocytes to the vascular endothelium is crucial in atherosclerosis development. Connexins (Cxs) which form hemichannels or gap junctions, modulate monocyte-endothelium interaction. We previously found that rutaecarpine, an active ingredient of the Chinese herbal medicine Evodia, reversed the altered Cx expression induced by oxidized low-density lipoprotein (ox-LDL) in human umbilical vein endothelial cells, and consequently decreases the adhesive properties of endothelial cells to monocytes. This study further investigated the effect of rutaecarpine on Cx expression in monocytes exposed to ox-LDL. In cultured human monocytic cell line THP-1, ox-LDL rapidly reduced the level of atheroprotective Cx37 but enhanced that of atherogenic Cx43, thereby inhibiting adenosine triphosphate release through hemichannels. Pretreatment with rutaecarpine recovered the expression of Cx37 but inhibited the upregulation of Cx43 induced by ox-LDL, thereby improving adenosine triphosphate-dependent hemichannel activity and preventing monocyte adhesion. These effects of rutaecarpine were attenuated by capsazepine, an antagonist of transient receptor potential vanilloid subtype 1. The antiadhesive effects of rutaecarpine were also attenuated by hemichannel blocker 18α-GA. This study provides additional evidence that rutaecarpine can modulate Cx expression through transient receptor potential vanilloid subtype 1 activation in monocytes, which contributes to the antiadhesive properties of rutaecarpine.
