The interaction between tumor-derived exosomes and stroma is crucial for tumor progression. However, the mechanisms by which tumor cells influence stromal changes are not yet fully understood. Our study revealed that high-metastatic renal cancer cells are more effective in converting normal fibroblasts into cancer-associated fibroblasts (CAFs) compared to low-metastatic renal cancer cells. Meanwhile, high-metastatic renal cancer cells secrete more exosomal miR-222-3p, which can directly target PANK3, activate NF-kB signaling pathway in fibroblasts and induce intracellular metabolic reprogramming to produce more lactic acid through Warburg effect. The activated CAFs further promote renal cancer progression by secreting lactic acid and inflammatory cytokines, including IL-6 and IL-8. Patients with renal cancer who have high levels of serum exocrine miR-222-3p are more likely to experience progression. These findings suggest that the intercellular communication between renal cancer cells and fibroblasts is facilitated by tumor exosomes. Targeting this communication may hold promise for the prevention and treatment of renal cancer.
