Levamisole treatment of the P5L cell line increases elaboration of extracellular inorganic pyrophosphate. (a) Treatment of the P5L-transduced cell line with levamisole results in a dramatic reduction in alkaline phosphatase (AP) activity. (b) Treatment with levamisole increases extracellular inorganic pyrophosphate (ePPi) in P5L-transduced cells. n = 3; *P ≤ 0.05.
