Figure 3. The oncology-related protein expressions altered by melatonin were measured by a proteome profiler oncology array. The relative expression of 84 human cancer-related proteins regulated by a 48-hour melatonin treatment (0 or 2 mM) was determined for (A) T24 and (B) UMUC3 cells. Protein expression changes in the (C) T24 and (D) UMUC3 cells were quantified and are depicted as bar plots.
