In the original publication [1], there was a mistake in “Figure 1C” as published. Specifically, due to an error by the art department during figure assembly, the same GAPDH blot used for TGF-β1 in the SEM-1 cells in Figure 5 was mistakenly used for cyclin D1 in the TCAM-2 cell line. The original blot for cyclin D1 in the TCAM-2 cells has now been restored. The corrected version of Figure 1 appears below. The authors confirm that the scientific conclusions are not affected by this correction. This correction has been approved by the Academic Editor. The original publication has also been updated.

Figure 1. (a,b) MTT assay in testicular cancer cells and HepG2 cells. TCAM-2 and SEM-1 cells were either left untreated or treated with increasing doses (15–200 µM) of OLE for 48 h. Cell proliferation is expressed in fold changes ± standard deviations (SDs) with respect to the basal conditions and is representative of three independent experiments, each performed in eight replicates. Statistical significance was considered at * p < 0.05; ** p < 0.001 NS = not significant. Statistical comparisons were drawn between groups using a one-tailed t-test. (-) = control. (c) Immunoblot showing the CD1 protein expression in TCAM-2 and SEM-1 cells exposed for 48 h to OLE (50 µM TCAM-2; 140 μM SEM-1). GAPDH was used as a loading control. The histograms represent the mean ± SD of three separate experiments (each performed in triplicate) in which band intensities were evaluated as the optical density and are represented as fold changes for treated vs. untreated cells normalized for the loading control. ** p < 0.001 and * p < 0.05 for treated vs. untreated cells. (d) Protein expression of p21Cip/WAF1 in TCAM-2 and SEM-1 cells exposed for 48 h to OLE (50 µM TCAM-2; 140 μM SEM-1). GAPDH was used as a loading control. As in (c), the histograms represent the mean ± SD of three separate experiments (each performed in triplicate), in which the band intensities were evaluated as the optical density and are represented as fold changes for treated vs. untreated cells normalized to the loading control. The numbers on the peaks reported on the top of each blot represent the size of the corresponding slot as a percentage of the total size of the two slots in each condition. * p < 0.05 for treated vs. untreated cells.
