[Retracted] Nanoemulsion and Encapsulation Strategy of Hydrophobic Oregano Essential Oil Increased Human Prostate Cancer Cell Death via Apoptosis by Attenuating Lipid Metabolism

Figure 4

Antiproliferative activity of prostate cancer cells (PC3) with or without OENE treatment. (a) The photographic picture was taken after performance MTT assay with or without OENE treatment; (b) antiproliferative activity of OENE with dose-dependent treatment and the antiproliferative activity was denoted (%); (c) IC₅₀ value of OENE in PC3 cells compared to that of positive control cisplatin. The cellular toxicity effect of OENE was also compared with normal cell line MRC-5; (d) cell morphology observation of PC3 was perceived using a phase-contrast microscope. The images are representative of three independent replicates. Each graph denotes the mean ± SE of triplicate experiments ( using Student’s t-test).
