However, its role in testicular germ cell tumors (TGCTs) remains unclear. This study aimed to evaluate Talin1 expression inTGCTs using integrated bioinformatics and immunohistochemical approaches. Differentially expressed genes were identified through  \nGEO and proteomics datasets. Venn diagram, Gene Ontology (GO), and protein-protein interaction (PPI) analyses revealed Talin1 as a key gene in cell adhesion and migration pathways. Prognostic relevance was assessed using TCGA and GTEx data. Talin1 expression was further examined via immunohistochemistry on 191 TGCT tissues. Results showed that reduced Talin1 expression was associated with higher pT-stage in seminomas (P = 0.036), embryonal carcinoma (P = 0.021), and teratomas (P = 0.044). It was also significantly linked to venous invasion (P = 0.021) and tunica vaginalis invasion (P = 0.049) in embryonal carcinoma, as well as hilum involvement and the presence of tumorinfiltrating lymphocytes in yolk sac tumors. These findings suggest that decreased cytoplasmic Talin1 expression correlates with aggressive tumor behavior and disease progression inTGCTs. Talin1 may have potential as a prognostic biomarker inTGCTs, though further functional studies are necessary to elucidate its mechanistic role and therapeutic significance.  \nKeywords Talin1, Testicular germ cell tumors (TGCTs), Embryonal carcinoma, Yolk sac tumor, Immunohistochemistry (IHC), Bioinformatics analysis  \nTesticular germ cell tumors (TGCTs) are the most commonly diagnosed cancer in young men, particularly in the age range of 20 to 40 years, with the prevalence steadily increasing globally, according to the World Health Organization’s Global Cancer Observatory (GLOBOCAN)1,2.  \nTGCTs account for more than 90% of all testicular cancers and are divided into two categories: those developed from germ cell neoplasia in situ (GCNIS) and those unrelated to GCNIS. The GCNIS subtypes include seminomas and non-seminomatous germ cell tumors (NSGCTs), which comprise embryonal carcinoma, yolk sac tumor, teratoma, choriocarcinoma, and mixed germ cell tumors3,4. While TGCTs are generally highly treatable and respond well to cisplatin-based chemotherapy, challenges persist in the form of short-and longterm complications, and a subset of patients eventually develop resistance to chemotherapy. Furthermore, the molecular mechanisms underlying TGCT development, recurrence, and metastasis remain poorly understood5.  \n1Oncopathology Research Center, Iran University of Medical Sciences (IUMS), Tehran, Iran. 2Department of Tissue Engineering & Regenerative Medicine, Faculty of Advanced Technologies in Medicine, Iran University of Medical Sciences (IUMS), Tehran, Iran. 3Department of Molecular Medicine, Faculty of Advanced Technologies in Medicine, Iran University of Medical Sciences (IUMS), Tehran, Iran. 4Hasheminejad Kidney Center, Pathology Department, Iran University of Medical Sciences (IUMS), Tehran, Iran. 5These authors contributed equally and are joint co-corresponding authors: Zahra Madjd and Leili Saeednejad Zanjani. 􀀍 email: [zahra.madjd@yahoo.com](zahra.madjd@yahoo.com);  \n[majdjabari.z@iums.ac.ir](majdjabari.z@iums.ac.ir); [saeednejadleily@yahoo.com](saeednejadleily@yahoo.com)  \n[www. nature.com/scientificreports/](www. nature.com/scientificreports/)  \nThe identification of new biomarkers is essential, as they can improve diagnosis, prognosis, and monitoring of diseases6,7.
