Throughout the biological world, transporters known as a multi-drug pumps protect healthy cells against toxic chemicals. In humans, they protect sensitive tissues such as the brain and accelerate the removal of chemicals via the gut.
Unfortunately, many cancers use multi-drug pumps to confer resistance to chemotherapy. Despite considerable research, there are no effective blockers for multi-drug pumps and their actions continue to thwart cancer chemotherapy. One of the major limiting factors is our inability to understand how these pumps recognise so many drugs.
Our team has developed a new model for the drug-recognition by one of these multi-drug pumps, P-glycoprotein. We predict that P-glycoprotein extracts drugs directly from the membrane and transfers them to a central cavity that propels them from cells.
Our project will test this model and locate the drug recognition sites on P-glycoprotein, thereby revealing the features of drugs recognised by the pumps This has not yet been achieved because technology is not appropriate to investigate multi-drug pumps. To overcome this, we have developed synthetic nanosystems that mimic biological membranes.
These membrane mimics will allow us to understand drug recognition by P-glycoprotein and eventually develop inhibitors to restore cancer chemotherapy. These membrane mimics will benefit nanotechnology to repurpose cellular systems to advance areas such as drug delivery, biological remediation and nanorobots for industrial and environmental purposes.
