Ziziphus Nummularia

Cardiovascular disease (CVD) continues to be the leading cause of death worldwide. Atherosclerosis is a CVD characterized by plaque formation resulting from inflammation-induced insults to endothelial cells, monocytes, and vascular smooth muscle cells (VSMCs). Despite significant advances, current treatments for atherosclerosis remain insufficient, prompting the search for alternative modalities, including herbal medicine. Ziziphus nummularia is an herb commonly used in the amelioration of symptoms associated with many health conditions such as cold, diarrhea, cancer, and diabetes. However, its effect on the inflammation-induced behavior of VSMCs remains unknown. In this study, we sought to determine the effect of the ethanolic extract of Z. nummularia (ZNE) on TNF-α-induced phenotypic changes of human aortic smooth muscle cells (HASMCs). The treatment of HASMCs with ZNE decreased cell proliferation, adhesion to fibronectin, migration, and invasion. ZNE treatment also caused a concentration- and time-dependent reduction in the TNF-α-induced expression of matrix metalloproteases MMP-2 and MMP-9, NF-κB, and cell adhesion molecules ICAM-1 and VCAM-1. Furthermore, ZNE decreased the adhesion of THP-1 monocytes to HASMCs and endothelial cells in a concentration-dependent manner. These data provide evidence for the anti-inflammatory effect of Ziziphus nummularia, along with potential implications for its use as an agent that could ameliorate inflammation-induced atherogenic phenotype of VSMCs in atherosclerosis.

Phagokinetic migration of cultured vascular cells was tested in response to human platelet-rich serum (‘serum’) and human platelet-poor plasma serum (‘plasma’). The cell types tested included bovine aortic endothelial cells, human umbilical vein endothelial cells, human haemangiomal capillary endothelial cells, bovine adrenal microvascular pericytes, and bovine aortic smooth muscle cells. Human serum stimulated a significant increase in the rate of migration for all five cell types. Human plasma stimulated the endothelial cells to migrate but had no effect on the migration of pericytes or smooth muscle cells. Highly purified platelet-derived growth factor (PDGF) stimulated dose-dependent migration of smooth muscle cells causing a 50% increase in phagokinetic track area relative to controls. Neither pericyte nor endothelial cell migration was stimulated by PDGF. Rabbit antiserum to human PDGF completely blocked the smooth muscle cell migration induced by either 10% serum or 1 ng/ml pure PDGF. Purified platelet factor IV (PF4) stimulated migration of pericytes but not of smooth muscle cells nor endothelial cells. Sheep antiserum to human PF4 completely blocked the pericyte migration induced by either 10% serum or 1 microgram/ml pure PF4. These results indicate that PDGF is the primary factor in serum responsible for the migration of cultured aortic smooth muscle cells and that PF4 is a critical factor required to induce the migration of pericytes. Other factors present in both plasma and serum control the migration of vascular endothelial cells.
