Effect of basil (Ocimum basilicum L.) blossoms aqueous extract on oxidative pressure markers HO-1 (a) and NQO1 (b) mRNA levels in MCF7 cells treated for both 24 and 48 h with different concentrations of basil (Ocimum basilicum L.) blossoms aqueous extract (0, 50, 150, and 250 µg/mL). From there on, the mRNA levels of HO-1 and NQO1 were measured utilizing RT-PCR and standardized to β-actin housekeeping gene. Data were recorded as means ± SEM (n = 5) of three free investigations. ***P < 0.001, **P < 0.01, *P < 0.05 contrasted and untreated cells
