To determine whether the reverse correlation between FFAR2 and TLR2/3 was associated with gene sets in the cancer module, we selected six NSCLC LTT samples (Fig. 1D: Group A, 3 LTTs with FFAR2DownTLR2UpTLR3Up; Group B, 3 LTTs with FFAR2UpTLR2DownTLR3Down) and performed GSEA (https://www.gsea-msigdb.org) between the Group A LTTs and the Group B LTTs. Here, TLR2 is linked to cancer.
