The effect of Sparstolonin B (SsnB) on gene expression in HUVECs. Homo sapiens

Sparstolonin B is a novel bioactive compound isolated from Sparganium stoloniferum, an herb historically used in Traditional Chinese Medicine as an anti-tumor agent. SsnB has previously demonstrated anti-angiogenic properties. In functional assays, SsnB inhibited endothelial cell tube formation (Matrigel method) and cell migration (Transwell method) in a dose-dependent manner. We used microarrays to examine how SsnB affected the gene expression of human umbilical vein endothelial cells (HUVECs), focusing in particular on pathways related to angiogenesis. Overall design: Two plates of HUVECs were exposed to 100 micromolar SsnB and two plates of HUVECs were exposed to Vehicle Control (1:1000 dilution of DMSO). After 24 hours, RNA was extracted for microarrays and gene expression was analyzed.
