AIM Failure of platinum chemotherapy is an unresolved issue in ovarian cancer. Targeted therapy has been added to the treatment options in solid cancers. Alvocidib is a cyclin dependent kinase inhibitor. MATERIALS AND METHODS This study evaluated the effects of alvocidib together with carboplatin on ovarian cancer cells (BG-1 and Skov-3) in vitro applying proliferation assays, cell cycle dist...

platelet aggregation beta amyloid main causes inflammation of neurons in alzheimer’s disease. in fact, creating this inflammation due to inappropriate actions in blood brain barrier (bbb) and astrocyte and microglia during the last century that studies conducted in this case nothing has been found. the only thing that can be done to prevent and reduce pro-inflammatory factors such as cytokines ...

We have investigated the contribution of drug accumulation and inhibition of heme polymerization to the in vitro activities of a series of antimalarial drugs. Only those compounds exhibiting structural relatedness to the quinolines inhibited heme polymerization. We could find no direct correlation between in vitro activity against chloroquine-susceptible or chloroquine-resistant isolates and ei...

Using a human myeloma cell line selected for resistance to doxorubicin (8226/DOX), which expresses the multidrug resistance phenotype, we studied the effects of drug accumulation on DNA damage and cytotoxicity in multidrug-resistant cells. The resistant 8226 subline showed a decrease in [14C]doxorubicin accumulation as compared to the sensitive (8226/S) subline at all time points investigated. ...

A leading bisthiazolium drug, T16, designed to mimic choline, was shown to exert potent antibabesial activity, with 50% inhibitory concentrations of 28 and 7 nM against Babesia divergens and B. canis, respectively. T16 accumulated inside Babesia-infected erythrocytes (cellular accumulation ratio, >60) by a saturable process with an apparent K(m) of 0.65 microM. Subcellular fractionation of Babe...

P-glycoprotein (Pgp), a membrane transporter encoded by the MDR1 gene in human cells, mediates drug efflux from cells, and it plays a major role in causing multidrug resistance (MDR). Confocal microscopy was used to study in vitro and in vivo drug accumulation, net uptake and efflux, and MDR modulation by P-glycoprotein inhibitors in MDR1-transduced human MDA-MB-435mdr (MDR) cancer cells. The M...

Expression of ABC family transporter proteins that promote drug efflux from cancer cells is a widely observed mechanism of multi-drug resistance of cancer cells. Cell adaptation in long-term culture of HL60 leukemic cells in the presence of chemotherapy leads to induction and maintenance of the ABC transporters expression, preventing further accumulation of drugs. However, we found that decreas...

In fact, creating this inflammation due to inappropriate actions in blood brain barrier (BBB) and astrocyte and microglia during the last century that studies conducted in this case nothing has been found.
