Extracellular vesicles (EVs) play a crucial role in cancer biology, particularly in the context of tumor progression and metastasis. A study demonstrated that exosomal miR-302b derived from human embryonic stem cells can rejuvenate aging mice by reversing the proliferative arrest of senescent cells, highlighting the potential of EVs in regenerative medicine (ref: Bi doi.org/10.1016/j.cmet.2024.11.013/). In glioblastoma, it was found that only tumor-derived large EVs (L-EVs), not those from immune cells, significantly drive tumor invasiveness, particularly in mesenchymal subtype cells, indicating a unique autocrine mechanism that promotes migration (ref: Tamborini doi.org/10.1093/neuonc/). Furthermore, circPRKD3-loaded exosomes were shown to inhibit STAT3 signaling, leading to tumor growth inhibition and remodeling of the glioblastoma microenvironment, emphasizing the complex interplay between EVs and tumor biology (ref: Zhang doi.org/10.1093/neuonc/). Additionally, the EXONERATE study highlighted the prognostic value of exosome-based liquid biopsies in predicting treatment responses in metastatic colorectal cancer, where high levels of specific exosomal markers correlated with poorer progression-free survival outcomes (ref: Xu doi.org/10.1158/1078-0432.CCR-24-1934/). Lastly, PSMA+ EVs were identified as biomarkers for stereotactic ablative radiotherapy in oligorecurrent prostate cancer, suggesting their potential utility in clinical decision-making (ref: Andrews doi.org/10.1158/1078-0432.CCR-24-3027/).
