Figure 3. By real-time RT-PCR, the expression analysis of E6, E7, P53, and Rb genes in cancerous HeLa cells and fibroblast cells. A and B, A significant decrease in the expression of E6 and E7 genes and increase in the expression of P53 and Rb genes were observed in HeLa cells; C, No significant variation was occurred by nano-curcumin treatment of Rb and P53 genes expression in normal fibroblast cells (significant at * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001).
