| 描述 |
beta-Escin (β-escin) selectively targets the glioblastoma-initiating cell population and reduces cell viability. β-escin-evoked attenuation of NF-κB-dependent signaling, increase in MMP-14 and decrease in COUP-TFII content and a rise in cholesterol biosynthesis could be beneficial in alleviating muscle-damaging processes. In rat model, β-escin rescues regenerating muscles from atrophy. The drug reduces inflammatory infiltration, increases the number of muscle fibers and decreases fibrosis. β-escin reduces macrophage infiltration into injured muscles and promotes their M2 polarization. It also alters transcription of muscle regeneration-related genes: Myf5, Myh2, Myh3, Myh8, Myod1, Pax3 and Pax7, and Pcna. In C2C12 myoblasts in vitro, β-escin inhibits TNF-α-induced activation of NF-κB, reduces secretion of MMP-9 and increases ALDH activity[3]. β-escin exerts inhibitory effect on the basic fibroblast growth factor (bFGF)-induced proliferation, migration and tube formation, as well as CAM (chorioallantoic membrane) angiogenesis in vivo. The inhibition of critical steps of angiogenic process observed with β-escin could be partially explained by suppression of Akt activation in response to bFGF[4]. β-escin sodium has a marked antiproliferative effect on A549 cells at least in part by inhibiting the JAK/STAT signaling pathway, but not by a cytotoxic effect[5]. |
