Celastrol, a natural biologically active compound isolated from Tripterygium wilfordii Hook F root extracts, has been shown to possess antitumor properties and therefore, is an interesting candidate for the development of novel chemotherapeutic cancer agents. In this study, we have demonstrated that
BACKGROUND
Hypoxia-inducible factor-1α (HIF-1α), a critical transcription factor to reduced O2 availability, has been demonstrated to be extensively involved in tumor survival, aggressive progression, drug resistance and angiogenesis. Thus it has been considered as a potential anticancer target.
Celastrol, a tripterine derived from the traditional Chinese medicine plant Tripterygium wilfordii Hook F. ("Thunder of God Vine"), has been reported to have multiple effects, such as anti-inflammation, suppression of tumor angiogenesis, inhibition of tumor growth, induction of apoptosis and
OBJECTIVE
To observe the effect of Tripterygium glycosides (TG) on the expression of hypoxia-inducible factor-1α and endothelin-1 in the kidney of diabetic rats and explore the possible mechanism underlying the protective effect of TG against diabetic nephropathy.
METHODS
Sixty 8-week-old male SD
Osteosarcoma is a common malignant bone tumor occurring in adolescents and children. The poor prognosis and low 5-year survival rate of osteosarcoma partly due to high metastasis of osteosarcoma. Triptolide (TPL), an extract from Tripterygium wilfordii, is widely used in cancer treatment. In our
Hypoxia-inducible factor-1 (HIF-1) is the central mediator of cellular responses to low oxygen and vital to many aspects of cancer biology. In a search for HIF-1 inhibitors, we identified celastrol as an inhibitor of HIF-1 activation from Tripterygium wilfordii. In the present study, we demonstrated
Triptolide (TP), a major active component of Tripterygium wilfordii Hook.F. (TWHF), is used to treat rheumatoid arthritis (RA). However, it has a narrow therapeutic window due to its serious toxicities. To increase the therapeutic index, a new triptolide-loaded transdermal delivery system, named
OBJECTIVE
Celastrol, a major active constituent of Tripterygium wilfordii, has antioxidant, anti-inflammatory, and anticancer effects. However, whether celastrol can exert protective effect on myocardial ischemia-reperfusion injury (MIRI) is unknown. The aim of this study was to test the protective
To observe the effect of Tripterygium Glycosides Tablets on angiogenesis of rats with type Ⅱ collagen-induced arthritis( CIA) and on the tube formation of human umbilical vein endothelial cells( HUVEC) in vitro. The HUVEC were induced by 20 μg·L-1 vascular endothelial growth factor( VEGF) in
