Extracellular Zn2+ -signaling, activated by the putative ZnR, enhanced cell growth of prostate cancer cells. Prostate cancer cell line, PC-3, was treated with Zn2+ -containing (100 µM, ten minutes) or Zn2+ -free Ringer’s solution daily, for five days. Cultures were then stained with crystal violet. Enhanced cell growth is shown in the cells treated with Zn2+ (right picture) compared with the control cells (left picture).
