[Corrigendum] Leptin promotes breast cancer cell migration and invasion via IL-18 expression and secretion

Following the publication of the above article and an Expression of Concern statement that was issued in light of concerns raised by an interested reader (doi: 10.3892/ijo.2025.5816) regarding potential duplications of data comparing Figs. 1D and 2E, and the apparent re‑use of β‑actin control data in Fig. 4A and B where different experimental conditions were reported, the authors have now responded to the enquiry posed by the Editorial Office. After consulting their original data, the authors have realized that the data in Fig. 2E for the MDA‑MB‑231 cell line, and the β‑actin blots in Fig. 4B, were chosen incorrectly (it was also noted by the Editorial Office, upon performing an independent analysis of the data in this paper, that, in Fig. 6C, the CD68/Lep. and CD163/CNL.+Lep. data panels appeared to contain an overlapping section of data, such that the data shown in these panels may have been derived from the same original source). The revised versions of Figs. 2 and 4 (showing the correct data for the MDA‑MB‑231 cell line in Fig. 2E and the β‑actin blots in Fig. 4B) are shown on the next two pages. Furthermore, a revised version of Fig. 6, showing replacement data for the CD68/Lep. data panel, is also shown on the third page. Note that the errors made in assembling these figures did not affect the overall results and conclusions reported in the paper. The authors are grateful to the Editor of International Journal of Oncology for granting them the opportunity to publish this corrigendum, and all the authors agree with its publication; furthermore, they apologize to the readership of the journal for any inconvenience caused.
