Plemper, R. Multidrug efflux pumps: substrate selection in ATP-binding cassette multidrug efflux pumps—first come, first served? Bcrp1 gene expression is required for normal numbers of side population stem cells in mice, and confers relative protection to mitoxantrone in hematopoietic cells in vivo. Woodward, O. For example, our data show that the extremely conserved R is crucial for proper protein folding, which is in line with a previous report showing that R is vital for ABCG2 biogenesis ATP-binding cassette ABC transporters make up a superfamily of transmembrane proteins that play a critical role in the development of drug resistance.

    In this study, the expression of ABCG2 transporter was not changed by Y 6 with different concentrations and incubated time Figure 3. This is reminiscent of vital salt-bridges verified in the corresponding ICL2 of human P-pg 71

    More recently, one group from Norway reported on amphiphilic sulfonated photosensitizers that were not effluxed out of breast cancer cells with high ABCG2 expression [ ].

    By contrast, yeast PDRs operate as full transporters that do not require dimerization to form a functional efflux pump Single amino acid substitutions in the transmembrane domains of breast cancer resistance protein BCRP alter cross resistance patterns in transfectants.

    Silencing the breast cancer resistance protein expression and function in caco-2 cells using lentiviral vector-based short hairpin RNA. Cell— e9 However, its use was limited in clinical patients because of its central nervous system neurotoxicity, although FTC was a classic ABCG2 reversal agent in experiments Rabindran et al.

    ABCG2/BCRP is referred to as a “half-type” ABC transporter, Importantly, many recently developed molecular-targeted cancer drugs, such as.

    The conformational switch is then enhanced by rigid movements of the transmission interface connecting the NBDs with TMDs. Marti-Renom, M. Cells were seeded onto cover glass in well plates. The transmission interface is essential for ABCG2 folding, surface targeting, transport function, substrate recognition, as well as ATP consumption during the catalytic cycle.

    discovered the third ABC transporters BCRP, which is encoded by ABCG2 [17]. BCRP is comprised of only one ATP-binding domain and a. Regulation and expression of the ATP-binding cassette transporter ABCG2 in Drug Transporter-Mediated Protection of Cancer Stem Cells From Ionophore.
    Cancer Biol Ther. Protein stability analysis by cycloheximide chase assay Stability of protein was performed by using cycloheximide to treat the cells at several time points to stop protein synthesis as described However, the application of EGCG was limited due to an unstable chemical profile that could be subjected to rapid oxidation and short duration of action because of multiple phenolic hydroxyl groups Lee et al.

    Some interesting studies have proposed the presence of multiple drug-binding sites in this ABC transporter,suggesting that kinase inhibitors may target these substrate-binding pockets. In this study, we performed the experiments on ABCG2-overexpressing cells and found that Y 6 was also effective in inhibiting ABCG2-mediated drug resistance at non-toxic concentrations.
