Single-cell landscape identified SERPINB9 as a key player contributing to stemness and metastasis in non-seminomas.

ABSTRACT: Embryonal carcinoma (EC), characterized by a high degree of stemness similar to that of embryonic stem cells, is the most malignant subtype within non-seminomatous testicular germ cell tumors (TGCTs). However, the mechanisms underlying its malignancy remain unknown. In this study, we employed single-cell RNA sequencing to analyze four non-seminoma samples. Our differential expression analysis revealed high expression of SERPINB9 in metastatic EC cells. We conducted in vitro experiments to further investigate SERPINB9's role in the progression of EC. Functionally, the knockdown of SERPINB9 in NCCIT and NTERA-2 leads to a diminished migratory capability and decreased cis-platin resistance, as demonstrated by Transwell migration assay and drug sensitivity assay. Moreover, embryoid bodies show
