A Correction on
Targeting NANOS1 in triple-negative breast cancer: synergistic effects of digoxin and PD-1 inhibitors in modulating the tumor immune microenvironment

By Wang T, Lei Y, Sun J, Wang L, Lin Y, Wu Z, Zhang S, Cao C and Wang H (2025) Front. Oncol. 14:1536406. doi: 10.3389/fonc.2024.1536406

There was a mistake in Figure 1B as published. The figure contains an error caused by an unintentional assembly mistake: while adjusting the layout to keep the spacing and formatting uniform, we duplicated a placeholder image that inadvertently overwrote the correct panel, resulting in incorrect image usage. The corrected Figure 1 and its caption appear below.

Figure 1
Panel A shows bar and line graphs comparing cell viability in MDA-MB-231 and 4T1 cells at different concentrations. Panel B displays images of cell migration and invasion with DMSO and TOE treatments, along with bar graphs quantifying migrative and invasive cells. Panel C presents a scatter plot of gene expression changes (log2 scale) showing upregulated and downregulated genes. Panel D illustrates a dot plot of enriched pathways with gene ratio and p-values, highlighting pathways in cancer and others.

Figure 1. TOE suppresses malignant phenotype of triple negative breast cancer cells. (A) The effect of TOE on cell proliferation in MDA-MB-231 and 4T1 cells. Cells were treated with varying concentrations of TOE for 24 hours, and cell proliferation was assessed using the CCK-8 assay. Data are expressed as the mean ± SEM (n = 3). Statistical significances were calculated via Student’s t-test. **p < 0.01 and ***p < 0.001 and ****p < 0.0001. (B) Transwell migration and invasion assay of MDA-MB-231 and 4T1 cells after treatment with TOE for 24 hours. Representative images of the migrated and invaded cells from randomly selected fields of Transwell inserts are shown on the left, while quantitative data for cell numbers are presented on the right. Cell numbers were calculated and expressed as the mean ± SEM of three independent experiments. Statistical significance was determined by t-test, with **p < 0.01 and ***p < 0.001 and ****p < 0.0001 indicating significant differences between TOE-treated and DMSO-treated cells. Scale bar = 100 μm. (C) MA plot of DGEs in MDA-MB-231 treated with TOE. (D) Enrichment and scatter map of KEGG pathway of DGEs.

There was a mistake in Figure 4B as published. The figure contains an error due to an unintentional mistake during assembly, where the “4T1-Invasion-Dig” image was overwritten by the “MDA-MB-231-Invasion-AA” image, resulting in incorrect image usage. The corrected Figure 4 and its caption appear below.

Figure 4
Graphs and images depict the effects of Dig and AA on cell viability, migration, and invasion in MDA-MB-231 and 4T1 cell lines. Graphs in panel A show decreased cell viability with increasing concentrations of Dig and AA. Panel B shows microscopic images of cell migration and invasion capabilities. Panel C presents bar charts summarizing migrative and invasive cell counts. Panel D displays images of tumors under different treatments. Panel E provides a scatter plot comparing tumor volumes across treatment groups. Panel F charts body weight changes over time for each treatment group.

Figure 4. Dig and AA inhibited tumor growth in breast cancer mouse models. (A) Inhibition of growth by Dig and AA in MDA-MB-231 and 4T1 cells for 24 h. MDA-MB-231 and 4T1 cells were treated with Dig and AA (at various concentration) for 24 hours, and cell proliferation was assessed using the CCK-8 assay. Data are presented as the mean ± SEM from three independent experiments (n = 3). Statistical significance was determined using unpaired t-tests, with *p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001 indicating significant differences compared to the DMSO control. (B) Transwell migration and invasion assay of MDA-MB-231 and 4T1 cells with Dig and AA treatment for 24 h. Representative images from randomly selected fields of transwell inserts, and Scalebar = 100 μm. (C) Quantitative data from the Transwell migration and invasion assays. Cell numbers were calculated and are expressed as the mean ± SEM of three independent experiments. * p < 0.05,** p < 0.01, *** p < 0.001 and ****p < 0.0001, as determined by unpaired t-tests. (D) Diagrammatic representation of tumor volume measurement. The diagram illustrates the measurement method, including caliper-based measurements of length and width used to calculate tumor volume (Volume = 1/2 × length × width^2). (E) Tumor sizes at day 14. (F) The body weight changes of mice in the period of 14 days after different treatments. The body weight of mice was monitored every 2 days after Dig and AA treatment. Data are expressed as the mean ± SEM. No significant changes in body weight were observed, suggesting that the treatments did not cause overt toxicity in mice.
