Our study aimed to clarify the effect of CAFs (cancer-associated fibroblasts), one major component of tumor microenvironment, on the chemoresistance of ESCC. By primary culture, two pairs of CAFs and matched NFs (normal fibroblasts) were isolated from tumor tissues of ESCC patients and matched normal esophageal epithelial tissues, respectively. The association of CAFs and chemoresistance was assessed in esophageal carcinoma cells, in xenograft tumor models and in clinical specimens of ESCC patients. We found CAFs conferred ESCC cells significant resistance to several common chemotherapeutic drugs including cisplatin, taxol, irinotecan (CPT-11), 5-fluorouracil (5-Fu), carboplatin, docetaxel, pharmorubicin, and vincristine. Mechanism studies revealed that blockage of CAFs-secreted TGFβ1 signaling by its receptor TGFβR1 inhibitor LY2157299 significantly reversed the chemoresistance in vitro and in vivo. Furthermore, the crosstalk of CAFs and ESCC cells enhanced the expression and activation of FOXO1, a member of the forkhead transcription factors in the O-box sub-family, inducing TGFβ1 expression in an autocrine/paracrine signaling loop. In 130 ESCC patients, the expression of TGFβ1 in CAFs was significantly associated with overall survival of patients treated with chemoradiotherapy. Together, our study highlighted TGFβ1 expressed in CAFs as an attractive target to reverse tumor chemoresistance, and can be used as an independent prognostic factor of ESCC patients treated with chemoradiotherapy. © 2016 Wiley Periodicals, Inc."xsd:string |
