ABSTRACT Prostate cancer (PCa) poses a significant global health challenge, particularly due to its progression into aggressive forms like neuroendocrine prostate (NEPC). This study developed and validated stemness-associated gene signature using advanced machine learning techniques, including Random Forest Lasso regression, applied large-scale transcriptomic datasets. The resulting 7-gene ( KMT5C, MEN1, TYMS, IRF5, DNMT3B, CDC25B DPP4 ) was across independent cohorts patient-derived xenograft (PDX) models. demonstrated strong prognostic value for progression-free, disease-free, relapse-free, metastasis-free, overall survival. Importantly, the not only identified specific NEPC subtypes, such as large-cell carcinoma, which is associated with very poor outcomes, but also predicted prognosis PCa cases that exhibit this molecular signature, even when they were histopathologically classified NEPC. dual classifier capability makes robust tool personalized medicine, providing valuable resource predicting disease guiding treatment strategies in management.

Background Increasing evidence indicates that cancer stem cells (CSCs) and stem-like form a special subpopulation of are ubiquitous in tumors. These exhibit similar characteristics to those normal tissues; moreover, they capable self-renewal differentiation, as well high tumorigenicity drug resistance. In prostate (PCa), it is difficult kill these using androgen signaling inhibitors chemotherapy drugs. Consequently, the residual (PCSCs) mediate tumor recurrence progression.

Special AT-rich sequence binding protein-2 (SATB2) is a nuclear matrix protein that binds to attachment regions and involved in chromatin remodeling transcription regulation. In stem cells, it regulates the expression of genes required for maintaining pluripotency self-renewal epithelial–mesenchymal transition (EMT). this study, we examined oncogenic role SATB2 prostate cancer assessed whether overexpression human normal epithelial cells (PrECs) induces properties (CSCs). The results demonstrate highly expressed cell lines CSCs, but not PrECs. Overexpression PrECs cellular transformation which was evident by formation colonies soft agar spheroids suspension. also resulted induction markers (CD44 CD133), pluripotency-maintaining factors (cMYC, OCT4, SOX2, KLF4, NANOG), CADHERIN switch, EMT-related factors. Chromatin immunoprecipitation assay demonstrated can directly bind promoters BCL-2, BSP, NANOG, MYC, XIAP, HOXA2, suggesting capable regulating pluripotency/self-renewal, survival, proliferation. Since CSCs play crucial initiation, progression, metastasis, effects knockdown on stemness. inhibited spheroid formation, viability, colony motility, migration, invasion compared their scrambled control groups. upregulated E-CADHERIN N-CADHERIN, SNAIL, SLUG, ZEB1. significantly higher adenocarcinoma tissues. Overall, our data suggest acts as an factor where inducing malignant changes CSC characteristics.
