Figure 4. Western blotting results of E7, P53, Rb, and GAPDH protein (as control) in nano-curcumin and curcumin-treated HeLa cells. A, Nanocurcumin treatment can decrease E7 protein expression and increase P53 and Rb proteins in cancerous HeLa cells more than curcumin significantly; B, Data has quantified by ImageJ software, and the significance of protein alterations was determined (significant at * P < 0.05, ** P < 0.01, *** P < 0.001).
