TRPV1 and leukemia: Thus oxaliplatin differs from Ara C (cytosine arabinoside - used for treating leukemia), which had the effect of abolishing capsaicin responses by blocking the insertion of TRPV1 ion channels in the cell membrane of human DRG neurons, but causing hypersensitivity when Ara C treatment was stopped, due to the reappearance of TRPV1 in the cell membrane [65].
