Objective: To investigate the effects of oridonin combined with capecitabine on the proliferaction of MDA-MB-231 human breast cancer cells. Methods: Effect of different concentrations(10, 20 and 40 μmol/L)of oridonin, capecitabine and their combination on the proliferation of MDA-MB-231 cells after
Aberrant activation of phosphatidylinosito-4,5-bisphosphate 3-kinase/protein kinase B (PI3K/AKT) signaling in cancer has led to pursuit of inhibitors for targeting this pathway. However, inhibitors of PI3K and AKT have failed to yield efficacious results without adverse effects. Here, we screened a
Oridonin, which is an ent-kaurene diterpenoid isolated from traditional Chinese medicine Rabdosia rubescens, displays various bioactivities, including anti-inflammation, anti-bacteria and anti-tumor. This study aimed to investigate the effect of oridonin on apoptosis of triple-negative breast cancer
Triple-negative breast cancer (TNBC) remains the leading cause of death among women with breast cancer worldwide. Oridonin is a natural anti-cancer compound that is isolated from the traditional Chinese herb Rabdosia rubescens. However, the antitumor efficacies of oridonin in the treatments of TNBC
Covalent drug discovery has undergone a resurgence in recent years due to comprehensive optimization of the structure-activity relationship (SAR) and the structure-reactivity relationship (SRR) for covalent drug candidates. The natural product oridonin maintains an impressive pharmacological profile
Oridonin (1) has attracted considerable attention in recent years because of its unique and safe anticancer pharmacological profile. Nevertheless, it exhibits moderate to poor effects against highly aggressive cancers including triple-negative and drug-resistant breast cancer cells. Herein, we
OBJECTIVE
To study the caspase-3-independent mechanisms in oridonin-induced MCF-7 human breast cancer cell apoptosis in vitro.
METHODS
The viability of oridonin-treated MCF-7 cells was measured by MTT (thiazole blue) assay. Apoptotic cells with condensed nuclei were visualized by phase contrast
Oridonin is an active diterpenoid, which was extracted from traditional Chinese herbs and had been widely used in clinical treatment nowadays. Oridonin phosphate is one of the derivatives of oridonin. In the present study, we explored its anti-tumor effect and investigated the molecular mechanism of
BACKGROUND
Oridonin is a diterpenoid isolated from Rabdosia rubescens with potent anticancer activity. The aim of our study is to investigate the role of oridonin to inhibit growth and metastasis of human breast cancer cells.
METHODS
The effect of oridonin on proliferation was evaluated by MTT
Ponicidin and oridonin are novel diterpenoids isolated from Rabdosia rubescens. We tested their effects in MCF-7 and MDA-MB-231 cells, as representing low and high invasive breast carcinoma, with normal MCF-10A cells. Clonogenicity and proliferation in MCF-7 cells were inhibited more significantly
The therapeutic outcomes of doxorubicin (Dox) treatment in breast cancer are limited by decreased drug efficiency and cardiotoxicity. The aim of this study was to investigate whether oridonin (Ori), a natural chemical abundant in the Chinese herb Isodon rubescens, might potentiate the anticancer
Triple-negative breast cancer (TNBC) is one of the most highly invasive and metastatic breast cancers without safe and effective therapeutic drugs. The natural product oridonin is reported to be a potential anti-TNBC agent. However, its moderate activity and complex structure hampered its clinical
Metastasis is the primary cause of mortality in patients with breast cancer and lacks effective therapeutic agents. Oridonin, an active diterpenoid compound isolated from Rabdosia rubescens, was identified to be the most potent anti-tumor ingredient. However, the molecular mechanisms responsible for
Oridonin, a natural tetracycline diterpenoid isolated from Chinese herb Rabdosia rubescens, has been reported to be a potent cytotoxic agent against a wide variety of tumors. However, its effect on highly metastatic breast cancer cells has not been addressed. In this study, we investigated the
The mechanism for anti-tumor activity of oridonin (ORI) nanosuspension, prepared by the high pressure homogenization method, was studied using MCF-7 human breast carcinoma cells in vitro. MTT assay, observation of morphologic changes, flow cytometric analysis, and western blot analysis indicated
