Doxorubicin selectively suppresses mRNA expression and production of endothelin-1 in endothelial cells.

Abstract：

:Doxorubicin (DXR) is a widely used cytostatic agent, but its administration is limited by its cardiovascular side effects. The endothelium is one of the largest organs in the human body and due to its direct contact with blood; it is exposed to the toxic effects of DXR. The aim of this study was to investigate in endothelial cells the effects of DXR on the expression of genes involved in cardiovascular diseases. We used in vitro cultured human umbilical vein endothelial cells (HUVEC) as a model; gene expression was assessed by SuperArray and qPCR. Out of the 96 representative genes of cardiovascular importance, the expression of only the ET-1 gene changed significantly. ET-1 mRNA expression was 10.9% of the untreated control (p=0.0049). This result was confirmed by qPCR (2.41% of control, p=0.0022). DXR also suppressed ET-1 production at protein level (p=0.0116). Both the early decrease in endothelial ET-1 production in the presence of DXR and the high plasma level of DXR during chemotherapy may influence the toxic effects of the drug.

  • Gleditsioside B, a triterpene saponin isolated from the anomalous fruits of Gleditsia sinensis Lam., abrogates bFGF-induced endothelial cell migration through preventing the activation of MMP-2 and FAK via inhibiting ERK and PI3K/AKT signaling pathways.

    abstract：:Angiogenesis has become an attractive target for the treatment of certain diseases such as cancer and rheumatoid arthritis. Our previous studies demonstrated that the saponin fraction from Gleditsia sinensis fruits had anti-angiogenic potential, and Gleditsiosides B (GB) was probably the main active constituent. In th...
