Inhibition of growth of canine-derived vascular endothelial cells by non-steroidal anti-inflammatory drugs and atrial natriuretic peptide

摘要

This study investigated the direct effects of non-steroidal anti-inflammatory drugs (NSAIDs) and atrial natriuretic peptide (ANP) on canine-derived vascular endothelial cells (VECs). VECs were isolated and cultured from canine arteries and veins. The mRNA expressions of vascular endothelial growth factor receptor 2, cyclooxygenase-2, and natriuretic peptide receptor 1 were detected in the cultured VECs. The viability of the cultured VECs was reduced in a dose-dependent manner by meloxicam, carprofen, and robenacoxib. By contrast, dose escalations of ANP had only marginal influence on the viability of cultured VECs. NSAIDs may potentially serve as not only analgesic agents against cancerous and perioperative pain but also as adjuvant anti-angiogenic drugs in dogs with malignant tumors.
