404) Co-culture of activating tumour cells with fibroblasts resulted in induction of transcripts associated with tumour cell invasion and growth, TGFβ1 and TGFBR1, SERPINE-1, BMP6, SPHK1 and MMP9.
* E-Cadherin and EpCAM expression by NSCLC tumour cells associate with normal fibroblast activation through a pathway initiated by integrin αvβ6 and maintained through TGFβ signalling.
- Fibroblasts in the tumour stroma (cancer-associated fibroblasts) influence tumour progression and response to therapeutics; little is known about the mechanisms through which the tumour cell co-opts a normal fibroblast. To study the activation of fibroblasts by tumour cells, a panel of non-small cell lung cancer (NSCLC) cell lines and normal human dermal fibroblasts were co-cultured. A subset of the NSCLC cells induced an activated cancer-associated fibroblast-like fibroblast phenotype defined by induction of fibroblast α-smooth muscle actin expression. Tumour cells that activated fibroblasts were associated with E-Cadherin and EpCAM expression and expression of integrin αvβ6. Co-culture of activating tumour cells with fibroblasts resulted in induction of transcripts associated with tumour cell invasion and growth, TGFβ1 and TGFBR1, SERPINE-1, BMP6, SPHK1 and MMP9. Fibroblast activation was inhibited by an αvβ6/8 integrin blocking antibody (264RAD) and a small molecule inhibitor of the TGF-beta type I receptor activin-like kinase (ALK5) (SB431542), demonstrating that transactivation of the TGFβ pathway initiates fibroblast activation. Both integrin and ALK5 antagonists inhibited initiation. Only ALK5 was effective when added after 3 days of co-culture. This suggests that although activation is αvβ6-dependent, once fibroblasts are activated alternative TGFβ pathway regulators maintain an activation loop. In co-culture activating cells had reduced sensitivity to selumetinib, AZD8931 and afatinib compared with mono-culture. In contrast, non-activating cells were insensitive to selumetinib and AZD8931 in both mono-culture and co-culture. In conclusion NSCLC cell lines, positive for E-Cadherin, EpCAM and αvβ6 expression, activate normal fibroblasts through avβ6/TGFβ signalling in vitro, and influence both gene expression and response to therapeutic agents.
