The mRNA expression of anti-apoptotic BCL-2 showed a marginally significant downregulation at the concentration of 100 μg/mL MTX compared to 400 μg/mL concentration (0.38 ± 0.11, p-value = 0.063); moreover, the BCL-2/BAX ratio -at x concentration of MTX-was significantly lower than 1:1 (0.33 ± 0.12, P-value = 0.019), implying the pro-apoptotic effect of this dose on RPE cells ( Figure 3B ).
