Summary
The overexpressed genes in FAP-positive CAFs from high TB-TNBCs included ZNF235, ANKRD30B, SLC26A2, SPDYC, CDKN1C, LIF, and FAM83A. The secreted LIF was found in 41.1% of TNBC cases with high levels detected in CAFs, while 26.2% of cases showed high LIF production in cancer cells. The recombinant LIF significantly promoted breast cancer cell migration and enhanced PD-L1 expression, effects that were attenuated by EC359. This study highlights the correlation of high TB in TNBC with poor prognosis and upregulation of key signaling pathways in CAFs. FAP-positive CAFs overexpress genes like LIF, which promotes cell migration and PD-L1 expression. LIF inhibition reduces these effects, suggesting LIF as a potential therapeutic target in TB-associated TNBC progression and immunotherapy.
