Cancer Associated Fibroblasts Promote Renal Cancer Progression Through a TDO/Kyn/AhR Dependent Signaling Pathway.

Cancer associated fibroblasts (CAFs) play crucial roles in cancer development, however, the specific mechanisms of CAFs associated renal cancer progression remain poorly understood. Our study observed enriched CAFs in high degree malignant tumor tissues from renal cancer patients. These CAFs isolated from tumor tissues are prone to facilitate drugs resistance and promote tumor progression and .
