Fig. 6. Quantification of NGF and BDNF mRNA levels by RT-qPCR in 1312N1 astrocytoma cells treated with either DMSO (negative control, 5 μg mL⁻¹), compound 1 (5 μg mL⁻¹), or compound 5 (5 μg mL⁻¹) for 48 h. Expression levels are given in fold changes with respect to the DMSO control. Data are means ± S.E.M from three independent experiments. **p < 0.05, *p < 0.10 in unpaired t-test.
