econazole nitrate (en), a synthetic compound, is now in use as a routine antifungal drug. en was shown to have antitumor effect, the tumor cell killing mechanisms, however, remain unclear. in this research, the apoptosis-inducing effect of en on mcf-7 cells was investigated. the results showed that en inhibited the proliferation of mcf-7 cells in a time- and dose-dependent manner by mtt method ...

background: many in vitro studies suggested that choline incorporation into many types of tumors is related to cell proliferation. whether in vivo choline incorporation is related also to cell proliferation or not was my question. therefore, the aim of this pilot study was to investigate the relationship of in vivo [methyl- 14c]-choline incorporation and in vivo [methyl-3h]- thymidine incorpora...

We explored whether p53 upregulated modulator of apoptosis (PUMA) gene transfection could enhance the sensitivity of epirubicin-induced apoptosis of MCF-7 breast cancer cells. The liposome-mediated recombinant eukaryotic expression vector PU-MA-pCDNA3 and empty vector plasmid were stably transfected into MCF-7 cells. Epirubicin (0.01-100 μM) was applied to MCF-7, MCF-7/PUMA, and MCF-7/pCDNA3 ce...

background: disulfiram is oral aldehyde dehydrogenase (aldh) inhibitor that has been used in the treatment of alcoholism. recent studies show that this drug has anticancer properties; however, its rapid degradation has limited its clinical application. encapsulation of disulfiram polymeric nanoparticles (nps) may improve its anticancer activities and protect rapid degradation of the drug. mater...
