Cancer‑associated fibroblasts drive colorectal cancer cell progression through exosomal miR‑20a‑5p‑mediated targeting of PTEN and stimulating interleukin‑6 production

This study evaluated the clinical relevance of a set of five serum-derived circulating microRNAs (miR‑ NAs) in colorectal cancer (CRC). Additionally, we investigated the role of miR-20a-5p released by exosomes derived from cancer-associated fibroblasts (CAFs) in the context of CRC.
