The multidrug resistance P-glycoprotein
1Imperial Cancer Research Laboratories, Institute of Molecular Medicine, University of Oxford, John Radcliffe Hospital, UK.
Abstract:
P-glycoprotein plays an important role in the resistance of cancers to chemotherapy. Thus, an understanding of the mechanism by which it functions, and its 'normal' physiological role, is of clinical relevance as well as intrinsic interest. Considerable progress towards this goal has been made in the last year or so. In addition, the finding that P-glycoprotein is associated with both a channel and a transporter activity has, potentially, far-reaching implications for an understanding of the nature of channels and transporters.
Insights
P-glycoprotein contributes to cancer chemotherapy resistance. Recent findings reveal its dual channel and transporter functions, offering new insights into its mechanisms and potential therapeutic targets.
