| Summary: | ABSTRACT Vesicle trafficking is an essential cellular process that plays an important role in tumour progression. Here, we performed a comprehensive transcriptomic and proteomic analysis on 50 clear cell renal cell carcinoma (ccRCC) tumour samples, and the data systematically depicted the alterations in the molecular landscape. Intriguingly, our investigation uncovered profound dysregulation of the vesicle trafficking process. Particularly, PDCD10 was overexpressed in ccRCC, and functional assays showed that PDCD10 promoted cell proliferation, migration and invasion in vitro and enhanced tumour growth in vivo. Additionally, we identified PDCD10 as a critical regulator of endocytosis and exosome secretion. Proteomic analysis of extracellular vesicles (EVs) suggested that PDCD10 overexpression altered the cargo content in EVs and elevated the abundances of cell adhesion and extracellular matrix molecules. Furthermore, Erlotinib treatment impaired PDCD10‐induced endocytosis and suppressed cell proliferation and invasion. Collectively, our findings underscore the significance of PDCD10 as a regulator of vesicle trafficking in ccRCC and a potential target for developing novel anticancer therapeutics. |
