Effects of HO and NA on the proliferation of MCF7 cells. A, B MCF7 viability after treatment with different concentrations of HO or NA. C represents the untreated control group, where cells were cultured under standard conditions without exposure to HO or NA. Statistical analysis was performed using GraphPad Prism 7.0 software (La Jolla, CA, USA) and the statistical significance was evaluated by a two-tailed Student’s t-test. *p < 0.05, **p < 0.01, and ***p < 0.001. Data are shown as mean ± SD (n = 3). C MCF7 viability after treatment with different concentrations of HO or HONA. C represents the untreated control group. Data are shown as mean ± SD (n = 3).
