Q

How does the lactate shunt work?

A
  • high energy demand
  • high glycolytic flux
  • NADH:NAD+ ratio increases
  • lactate shunt regenerates NAD+
  • allows glycolysis to continue
  • inefficient but quick method to produce ATP very quickly

Q

How is targeting the Warburg effect therapeutic?

A
  • inhibiting MCT channel
  • intracellular accumulation of lactic acid
  • drop in pH
  • cell death
  • only targets cells using lactate shunt

Q

What is synthetic lethality?

A
  • when a combination of two events results in cell death
  • e.g. presence of FH and haemophilia inhibition
