Inhibitory effect of cryptotanshinone on angiogenesis and Wnt/β-catenin signaling pathway in human umbilical vein endothelial cells
摘要
To investigate the anti-angiogenic effect of cryptotanshinone (CPT) on human umbilical vein endothelial cells (HUVECs) and the effect of CPT on Wnt/β-catenin signaling pathway. HUVECs were incubated with 0
2.5
5
10
and 20 μ mol/L CPT for detecting cell viability with dimethyl thiazolyl-2
5-diphenyltetrazolium bromide (MTT) assay. Then
HUVECs were incubated with 0
2.5
5
and 10 μ mol/L CPT for detecting endothelial cell migration
invasion
and tubular-like structure formation with wound healing
transwell invasion and matrigel tube formation assays
respectively. To gain insight into CPT-mediated signaling
the effects of CPT on T-cell factor/lymphocyte enhancer factor (TCF/LEF) transcription factors were detected by the Dual-luciferase reporter assay. Next
the nuclear expression of β-catenin was evaluated using Western blot and immunochemistry. Finally
vascular endothelial growth factor (VEGF) and cyclin D1
downstream proteins of the Wnt pathway were examined with Western blot. CPT dose-dependently suppressed endothelial cell viability
migration
invasion
and tubular-like structure formation. In particular
CPT blocked β-catenindependent transcription in HUVECs in a dose-dependent manner. In Western bolt
10 μ mol/L CPT decreased expression of β-catenin in nucleus of HUVECs (P<0.01). In immunohistochemistry
β-catenin was more potent in response to LiCl (an activator of the pathway) treatment. However
the signals were weaker in the nucleus of the CPT (10 μ mol/L) group
compared to the positive control. Also
VEGF and cyclin D1 were both eliminated by CPT in 5 and 10 μ mol/L doses (P<0.05). Our study supported the role of CPT as an angiogenic inhibitor
which may impact on the Wnt/β-catenin signaling pathway.
