Correction to: Scientific Reports https://doi.org/10.1038/s41598-020-70516-x, published online 13 August 2020.
As a result of errors during figure assembly, an incorrect image for GAPDH blot was used in Fig. 5D, and the GAPDH blot in Fig. 5C was horizontally flipped (correct images were included in the Supplementary Information file at the time of publication). The original Fig. 5 and accompanying legend appear below.
Apoptotic protein expression levels in DKPs treated and un-treated HT-29 cells for 24 h. (A–D) Effect of DKPs on the expression of apoptosis-related proteins in the whole-cell lysate of DKP-1: cyclo (l-Pro-l-Leu) (A), DKP-2: cyclo (l-Pro-l-Val) (B), DKP-3: cyclo (l-Pro-l-Phe) (C), and DKP-4: cyclo (l-Pro-l-Tyr) (D) for 24 h. (E–H) Effect of DKPs on the cytochrome-c levels from the mitochondrial and cytosolic fraction of DKP-1: cyclo (l-Pro-l-Leu) (E), DKP-2: cyclo (l-Pro-l-Val) (F), DKP-3: cyclo (l-Pro-l-Phe) (G), and DKP-4: cyclo (l-Pro-l-Tyr) (H). Western blot analysis was performed using antibodies against CytC, Bid, and GADH served as a housing gene. Data were presented as the mean ± SD (n = 3). Data were analyzed by one-way ANOVA with student’s two-tailed t-test. The asterisks *p < 0.05, **p < 0.001, ***p < 0.0001, ****p < 0.0001, indicates a significant difference between the control in response to DKPs treaments. The groupings were cropped from different gels subjected to identical conditions. Full blots were shown in the Supplementary Information, Fig. S4A–H.
Additionally, in Fig. 6A an incorrect image was included for the zebrafish embryo in DKP-1 at 200 µM. The original Fig. 6 and accompanying legend appear below.
Developmental changes in the zebrafish embryos after treatment with different doses of four cyclic dipeptides. Representative images for 24 hpf (A), 48 hpf (B), 72 hpf (C), and 96 hpf (D). CTL Control, DMSO Vehicle control (DMSO).
