Curcumin treatment leads to decrease in invasive property and colony formation ability. a Colony formation assay following treatment of CAL 27 cells with curcumin or vehicle (DMSO). b A graphical representation of the colony forming ability of the CAL 27 cells upon treatment with curcumin or vehicle (DMSO). c CAL 27 cells were treated with either curcumin or vehicle (DMSO) for 48 h and invasive property of the cells were monitored. Cells that migrated are visualized using methylene blue. d A graphical representation of the invasive ability of the CAL 27 cells in presence of curcumin or vehicle (DMSO). e Phosphotyrosine profile of CAL 27 cells treated with curcumin for 0, 1 and 4 h analyzed by Western blotting using anti-phosphotyrosine antibody (Cat # 16-316)
