Research Interests

Ion channels and signalling in cancer cells and neurons

My lab studies the ways in which ion channels control membrane potential and intracellular calcium signalling, particularly in neuroendocrine-differentiated cancer cells. Cancers such as pancreatic neuroendocrine tumours, small-cell lung cancer and some breast and prostate cancers show neural characteristics, including excitability and vesicular release of peptides and neurotransmitters. We are interested in how such signalling participates in the invasiveness and progression of these cancers. We are also interested in membrane potential and calcium signalling in mammalian central neurons. We use a combination of patch-clamp and optical recording techniques, cell culture and computational modelling.

Above: Technique used to induce mechanical-rupture-induced necrosis of a mouse PanNET cell, while recording from another with a patch-clamp electrode (right). The fire-polished glass microprobe is advanced rapidly at time 0 through the cell at the left, using a piezoelectric manipulator, and withdrawn after 1 second, causing immediate membrane rupture and consequent cell death.

Above: Cell membrane rupture activates NMDARs. Rupture of one cell (during gray bar) evokes a large activation of NMDARs, over tens of seconds (black trace), in another cell situated at a distance of 80 μm. Low-noise whole-cell recording allows resolution of single NMDAR channel openings (right). The approximate time course of glutamate concentration at the surface of the recorded cell is shown in red. This is obtained by solving the diffusion equation for an instantaneous point release of 2×10-14 moles of glutamate at the site of necrosis (release of the cytoplasm of a 2 pL cell containing 10 mM glutamate).
