Ascorbate can act as an oxidant to induce tumor cell death at a pharmacological dose. Here the authors show that this response is associated with increases in GPCR Gi/o activity. This effect promotes rises in intracellular Ca2+ influx through transient receptor potential channel activity in retinoblastoma cells.
