Testicular GCTs (TGCTs) are the predominant solid tumors in adolescents and young men. Despite cisplatin serving as the primary therapeutic intervention for TGCTs, 10‑20% of patients with advanced disease demonstrate resistance to cisplatin‑based chemotherapy, and epithelial‑mesenchymal transition (EMT) is a potential contributor to this resistance. EMT is regulated by various factors, including the snail family transcriptional repressor 2 (<i>SLUG</i>) transcriptional factor, and, to the best of our knowledge, remains unexplored within TGCTs. Therefore, the present study investigated the EMT transcription factor <i>SLUG</i> in TGCTs. <i>In silico</i> analyses were performed to investigate the expression of EMT markers in TGCTs. In addition, a cisplatin‑resistant model for TGCTs was developed using the NTERA‑2 cell line, and a mouse model was also established. Subsequently, EMT was assessed both <i>in vitro</i> and <i>in vivo</i> within the cisplatin‑resistant models using quantitative PCR and western blot analyses. The results of the <i>in silico</i> analysis showed that the different histologies exhibited distinct expression profiles for EMT markers. Seminomas exhibited a lower expression of EMT markers, whereas embryonal carcinomas and mixed GCT demonstrated high expression. Notably, patients with lower <i>SLUG</i> expression had longer median progression‑free survival (46.4 months vs. 28.0 months, P=0.022). In the <i>in vitro</i> analysis, EMT‑associated genes [fibronectin; vimentin (<i>VIM</i>); actin, α2, smooth muscle; collagen type I α1; transforming growth factor‑β1; and <i>SLUG</i>] were upregulated in the cisplatin‑resistant NTERA‑2 (NTERA‑2R) cell line after 72 h of cisplatin treatment. Consistent with this finding, the NTERA‑2R mouse model demonstrated a significant upregulation in the expression levels of VIM and SLUG.

The MTT assay was used to assess cell viability, cytotoxicity was measured using a lactate dehydrogenase cytotoxicity assay, and Annexin V‑FITC/PI flow cytometric analysis was used to analyze early and late cell apoptosis.

Owing to the fact that some of the abovementioned data had already apparently been published previously, the Editor of <i>Molecular Medicine Reports</i> has decided that this paper should be retracted from the Journal. The authors were asked for an explanation to account for these concerns, but the Editorial Office did not receive a reply. The Editor apologizes to the readership for any inconvenience caused.
