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,
Celastrol, an anti-oxidant flavonoid that is widely distributed in the plant kingdom, has been suggested to have chemopreventive effects on cancer cells: however, the mechanism of this process is not completely understood. In this study, we found that celastrol suppressed the viability of breast
BACKGROUND Celastrol is extracted from the root of the Chinese traditional herb Tripterygium wilfordii, which has anti-cancer effects in multiple cancers. However, the effect of celastrol on the metastasis of triple-negative breast cancer and its mechanism remain largely unknown. MATERIAL AND
Celastrol is used in traditional Chinese medicine for treating cancers. However, its low water solubility and poor tumour selection represent major pitfalls for clinical application. In the present study, gold nanoparticle (AuNP) firstly was conjugated with PVP-co-2-dimethylaminoethyl methacrylate
As one of the main components of Tripterygium wilfordii Hook F, celastrol (CSL) has significant antitumor activity, but its clinical application has been limited by its poor solubility, low oral bioavailability and systemic toxicity. In this study, celastrol nanosuspensions (CSL-NSps) were prepared
A codelivery system that sequentially releases its contents is an effective strategy to enhance anticancer efficacy. Here, we fabricated multicomponent-based liposomes (T/CM-L) loaded with sodium tanshinone IIA sulfonate (STS) and a small-sized microemulsion of celastrol (CM), which shows
Signaling via the phosphatidylinositol-3 kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) is crucial for divergent physiological processes including transcription, translation, cell-cycle progression and apoptosis. The aim of work was to elucidate the anti-cancer effect of celastrol and the
Human estrogen receptor α (ERα) is a nuclear transcription factor that displays a major therapeutic target for breast cancer. The transcriptional activity of ERα can be regulated by particular estrogen receptor modulators. Celastrol, a quinine methide triterpene extracted from a Chinese medicine
The receptor tyrosine kinase ErbB2 is overexpressed in up to a third of breast cancers, allowing targeted therapy with ErbB2-directed humanized antibodies such as Trastuzumab. Concurrent targeting of ErbB2 stability with HSP90 inhibitors is synergistic with Trastuzumab, suggesting that
OBJECTIVE
To investigate the effect and related molecular mechanisms of lapatinib/celastrol combination or single-agent treatment in HER2/neu-overexpressing MDA-MB-453 breast cancer cells.
METHODS
The effects of treatment with lapatinib, celastrol or their combination on cell growth were determined
OBJECTIVE
Metastasis is one of the main causes of death for patients with malignant tumors. Induction of matrix metalloproteinase (MMP)-9 is particularly important for the invasiveness of various cancer cells. Celastrol, a triterpenoid isolated from the traditional Chinese medicine, is known to
Metastasis is one of the major obstacles for successful therapy of breast tumor. To inhibit the metastasis and growth of breast tumor simultaneously, a Celastrol (Cela) loaded glucolipid-like conjugates (CSOSA/Cela) with αvβ3-ligand Tetraiodothyroacetic acid (TET) modification (TET-CSOSA/Cela) were
Background
Celastrol is a major active component of the thunder god vine (
Tripterygium wilfordii) used in traditional Chinese medicine to treat chronic inflammatory and autoimmune diseases.
Celastrol inhibits PI3K-Akt-mTOR signaling, which is frequently dysregulated in
The aim of the present study was to evaluate the underlying apoptotic mechanisms of celastrol, a major biologically active component of Tripterygium regelii, in human breast adenocarcinoma MCF-7 cells. Celastrol was isolated from T. regelii chloroform extract by silica gel column chromatography, and
BACKGROUND
Evaluation of novel drugs for clinical development depends on screening technologies and informative preclinical models. Here we developed a multicolor bioluminescent imaging platform to simultaneously investigate transcription factor NF-κB signaling and apoptosis.
METHODS
The human
