In the present study, we investigated whether treatment with cepharanthine, a biscoclaurine alkaloid extracted from Stephania cepharantha improves the response to radiotherapy in the oral squamous cell carcinoma (OSCC) cell lines, HSC2, HSC3 and HSC4. We examined the potential mechanisms that may

Suppression of tumor necrosis factor alpha-induced matrix metalloproteinase 9 production in human salivary gland acinar cells by cepharanthine occurs via down-regulation of nuclear factor kappaB: a possible therapeutic agent for preventing the destruction of the acinar structure in the salivary glands of Sjögren's syndrome patients.

Mutant p53 is primarily responsible for ineffectiveness of many anticancer drugs. The present study showed that cepharanthine alone or combined with 5-fluorouracil effectively controlled the growth of HT-29 human colorectal cancer cells harboring mutant p53 both in vitro and in vivo. The combination

Cepharanthine (CEP), a biscoclurine alkaloid isolated from Stephania cepharantha Hayata, has demonstrated anticancer activity in several different types of cancer cells. Colorectal cancer (CRC) is one of the most common cancers in both men and women. Mutated p53 in CRC was reported to be associated

A study on the antitumor effect and distribution to tumor tissue of 1-(2-tetrahydrofuryl)-5-fluorouracil (FT-207) when administered with cepharanthine was performed using RPMI 4788 human colon cancer cell line or murine Sarcoma-180 tumor cells in vitro and in vivo. Combined treatment with FT-207 or

Inhibition of autophagy is a promising strategy for non-small cell lung cancer (NSCLC) treatment, which is in the clinical trials. However, only chloroquine is used in clinic as an autophagic inhibitor and the inhibitory effect of chloroquine on autophagy is finite. Therefore, the development of an
