Triptolide is a principal diterpene triepoxide from the Chinese medical plant Tripterygium wilfordii Hook. f., whose extracts have been utilized in dealing with diverse diseases in traditional Chinese medicine for centuries. Recently, the antitumor effect of triptolide has been found in several
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
Triptolide (TPL), a diterpenoid triepoxide purified from the Chinese herb Tripterygium wilfordii Hook F, has been reported to potentiate the anti-tumor effect in various cancer cells. However, the effect of TPL on oral cancers is not yet evaluated. Herein we first demonstrate that TPL induces
Triptolide, a diterpene triepoxide compound extracted from the traditional Chinese medicine herb Tripterygium wilfordii Hook F., is a potential cancer chemotherapeutic for tumors. However, the mechanism of anti-proliferative mechanism of triptolide in colon cancer cells is not entirely clear.
A leading cause of cancer chemotherapy failure is chemoresistance, which often involves multiple mechanisms. Chinese medicines (CM) usually contain multiple components which could potentially target many mechanisms simultaneously and may offer an advantage over single compounds that target one
BACKGROUND
Tripterygium hypoglaucum (levl.) Hutch (Celastraceae) (THH) root is a traditional Chinese medicinal herb commonly used for treating autoimmune diseases and cancer. Alkaloid is one of the most bioactive components of THH extract. To evaluate the in vitro and in vivo antitumor properties of
Androgen receptor(AR) plays an important role in the maintenance of prostate function and development of prostate cancer. AR is the key target in the therapy of prostate cancer. In this study, a cell-based screening assay was established by dual-luciferase reporter system to analyze the activity of
Celastrol is a quinone methide triterpene derived from Tripterygium wilfordii Hook F., a plant used in traditional medicine. In the present study, we reported that celastrol potentiated tumor necrosis factor-α (TNF-α)-induced apoptosis, affected activation of caspase-8, caspase-3 and PARP cleavage,
TNF-related apoptosis-inducing ligand (TRAIL/Apo- 2L), a newly identified member of the TNF family promotes apoptosis by binding to the transmembrane receptors (TRAIL-R1/DR4 and TRAIL-R2/DR5). TRAIL known to activate NF-kappaB in number of tumor cells including A549 (wt p53) and NCI-H1299 (null p53)
BACKGROUND
Tumour cells can be induced to undergo apoptosis after treatment with the tumour necrosis factor α-related death-inducing ligand (TRAIL). Although human pancreatic cancer cells show varying degrees of response they can be sensitised to the pro-apoptotic effects of TRAIL in the presence of
Triptolide (Tri) is a diterpenoid triepoxide isolated from Tripterygium wilfordii Hook F. The effects of Tri on the colony formation of breast cancer cell lines MCF-7 and BT-20, stomach cancer cell lines MKN-45, MKN-7, and KATO-III, and promyelocytic leukemia cell line HL-60 were reported. Using
The aim of the study was to discover possible differential cytotoxicity of triptolide towards estrogen-sensitive MCF-7 versus estrogen-insensitive MDA-MB-231 human breast cancer cells. Considering that MCF-7 cells express functional Estrogen receptor alpha (ERalpha) and wild-type p53, whereas
Tumor necrosis factor-related apoptosis-inducing ligand (Apo2L/TRAIL) belongs to the family of programmed cell death-inducing cytokines. Apo2L/TRAIL induces apoptosis in a wide variety of tumor cells. Tumor cells that are resistant to Apo2L/TRAIL-induced apoptosis can be sensitized by
Lung cancer is one of the most common malignant cancers in the world. Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) is a second- or third-line therapy for mutated non-small cell lung cancer (NSCLC). It usually becomes drug resistance after a period of treatment. Triptolide
Triptolide, the main active component obtained from Tripterygium wilfordii Hook. f, has been reported to present potent immunosuppressive and anti-inflammatory biological activities. It has been previously shown that due to the cytotoxicity of triptolide it has a limited use in the clinic. Although
