Bromocriptine reverses P-glycoprotein-mediated multidrug resistance in tumor cells.
One of the most important causes of anticancer treatment failure is the development of multidrug resistance (MDR). The main characteristics of tumor cells displaying the MDR phenomena are cross-resistance to structurally unrelated cytotoxic drugs having different mechanisms of action and the overexpression of the MDR1 gene, which encodes a transmembrane glycoprotein named P-glycoprotein (P-gp)....
متن کاملThe survivin suppressant YM155 reverses doxorubicin resistance in osteosarcoma.
Doxorubicin (DOX) is one of the widely used chemotherapeutic drugs for the treatment of human osteosarcoma (OS). However, acquisition of DOX resistance is common in patients with OS, leading to local and distant failure. In this study, we demonstrate that survivin expression is significantly upregulated in OS primary tumors compared to paired normal tissue. In addition, survivin expression was ...
متن کاملCrizotinib (PF-02341066) reverses multidrug resistance in cancer cells by inhibiting the function of P-glycoprotein.
BACKGROUND AND PURPOSE Besides targeting the well-known oncogenic c-Met, crizotinib is the first oral tyrosine kinase inhibitor inhibiting anaplastic lymphoma kinase (ALK) in clinical trials for the treatment of non-small cell lung cancer. Here, we assessed the possible reversal of multidrug resistance (MDR) by crizotinib in vitro and in vivo. EXPERIMENTAL APPROACH 1-(4,5-Dimethylthiazol-2-yl...
متن کاملCo-treatment by docetaxel and vinblastine breaks down P-glycoprotein mediated chemo-resistance
Objective(s): Chemoresistance remains the main causes of treatment failure and mortality in cancer patients. There is an urgent need to investigate novel approaches to improve current therapeutic modalities and increase cancer patients' survival. Induction of drug efflux due to overexpression of P-glycoproteins is considered as an important leading cause of multidrug resistance...
متن کاملPseudolaric acid B inhibits angiogenesis and reduces hypoxia-inducible factor 1alpha by promoting proteasome-mediated degradation.
PURPOSE Pseudolaric acid B (PAB), the naturally occurring diterpenoid isolated from the root bark of Pseudolarix kaempferi Gordon tree (Pinaceae), possesses potent antifungal and pregnancy-terminating effects that may be tightly associated with angiogenesis. This study was to examine its angiogenic inhibition, impact on vascular endothelial growth factor (VEGF) secretion from tumor cells and th...
