Following publication of the original article [1], the authors identified a minor error in Fig. 7; specifically:

• Fig. 7d: Incorrect immunohistochemistry staining image used for CPEB4/sh-cDOPEY2 (first row, second column); correct image now used

The corrected figure is given here. The correction does not have any effect on the final conclusions of the paper. The original article has been corrected.

Fig. 7

cDOPEY2 attenuates cisplatin resistance in vivo. A Schematic diagram demonstrating the grouping and treatment plan of the xenograft model; BALB/c nude mice were inoculated with the indicated cells (5 × 10⁶) and treated with cisplatin (i.p., 1 mg/kg) every two days until the tumor volume exceeded 100 mm³. B Representative images of the inoculated tumor tissues of each group. C Time-course evaluation of the tumor volumes in the indicated groups as measured every 5 days and tumor weights measured after tumors were harvested. D IHC staining showing the abundances of CPEB4, Mcl-1, and Ki-67 in the indicated groups. Scale bars, 100 μm. Data are presented as the mean ± SD. *P < 0.05, **P < 0.01, ***P< 0.001. P values were determined by one-way ANOVA with Tukey’s post hoc test
