Reversal effect of Stephania tetrandra-containing Chinese herb formula SENL on multidrug resistance in lung cancer cell line SW1573/2R120.

Numai utilizatorii înregistrați pot traduce articole

This research is aimed on reversing multidrug resistance (MDR) of chemotherapy in lung cancer. According to our previous research, chemotherapeutic drugs resistance in lung cancer is mainly due to high expression of multidrug resistance-associated protein (MRP) gene and activation of caspases. The

Inactivation of the orphan nuclear receptor NR4A1 contributes to apoptosis induction by fangchinoline in pancreatic cancer cells.

Numai utilizatorii înregistrați pot traduce articole

Previous studies have demonstrated that the orphan nuclear receptor NR4A1 is overexpressed in human pancreatic cancer and antagonizing this receptor promotes apoptosis and inhibits pancreatic cancer cells and tumor growth. In the present study, we identified fangchinoline, a

The enhancement of tumor radioresponse by combined treatment with cepharanthine is accompanied by the inhibition of DNA damage repair and the induction of apoptosis in oral squamous cell carcinoma.

Tetrandrine is a bisbenzylisoquinoline alkaloid found in Stephania tetrandra, a Chinese medicine commonly used as an anti-inflammatory. It has extensive pharmacological activity, including positive ion channel blockade and inhibition of multiple drug resistance proteins. These activities are very

c-Jun NH2-terminal kinase-induced proteasomal degradation of c-FLIPL/S and Bcl2 sensitize prostate cancer cells to Fas- and mitochondria-mediated apoptosis by tetrandrine.

Numai utilizatorii înregistrați pot traduce articole

Tetrandrine, a constituent of Chinese herb Stephania tetrandra, causes cell death in prostate cancer, but the molecular mechanisms leading to apoptosis is not known. Here we demonstrated that tetrandrine selectively inhibits the growth of prostate cancer PC3 and DU145 cells compared to normal

Fangchinoline inhibits the proliferation of SPC-A-1 lung cancer cells by blocking cell cycle progression.

Cepharanthine, a biscoclaurine alkaloid extracted from Stephania cepharantha Hayata was examined for a possible apoptosis-inducing effect in murine P388 doxorubicin-sensitive (P388/S) and -resistant (P388/DOX) cells. A significant increase in LDH release from cells was observed after P388/S and

Preventive effects of a biscoclaurine alkaloid, cepharanthine, on endotoxin or tumor necrosis factor-alpha-induced septic shock symptoms: involvement of from cell death in L929 cells and nitric oxide production in raw 264.7 cells.

The preventive effects of cepharanthine, a biscoclaurine alkaloid isolated from Stephania cepharantha Hayata, on the lethality and cell death caused by endotoxin or tumor necrosis factor (TNF)-alpha-induced syndrome in septic shock were investigated. In these experiments, we estimated the survival

[Synergistic interaction between Ys-96, a bisbenzylisoquinoline compound derived from Stephania tetrandra, and adriamycin or vincristine against human cancer cell lines in vitro].

OBJECTIVE To study in vitro the anticancer interaction between Ys-96, a bisbenzylisoquinoline compound derived from Stephania tetrandra, and adriamycin or vincristine against human cancer cell lines. METHODS Using human breast cancer cell MCF-7 and its adriamycin-resistant cell line MCF-7/Adr, and

Tetrandrine and fangchinoline, bisbenzylisoquinoline alkaloids from Stephania tetrandra can reverse multidrug resistance by inhibiting P-glycoprotein activity in multidrug resistant human cancer cells.
