NGF attenuated PA-induced cell death in RGC-5 cells.

(A) Cell viability was determined by MTT assays; (B, C) apoptosis of cells was measured by the Annexin V-FITC/PI assay. Results are shown as the mean ± SEM and represent three independent experiments (n = 6 for MTT, n = 3 for flow cytometry, one-way analysis of variance and least significant difference post hoc test). *P < 0.05, vs. control group; #P < 0.05, vs. PA group. OD: Optical density; PA: palmitic acid; NGF: nerve growth factor.
