Short exposure of Daoy medulloblastoma cells to R-verapamil in vitro slows xenograft tumor formation in vivo . Staircase plot shows tumor incidence over time for cells exposed to R-verapamil (or carrier alone) for five days prior to subcutaneous flank injection, with n = 10 mice per treatment. Curves are significantly different by the log-rank (Mantel-Cox) test, p-value < 0.01.
