TNFSF4 and non-small cell lung carcinoma: As the NFκB transcripts NFKB1 and RELA (encoding p50 and p65, respectively) were downregulated in H1975-TECs (Supplementary Figure 4F), and that the phosphorylated form of p65 (a mark for the NFKB canonical pathway activation) was diminished in H1975- and A549-TECs (Supplementary Figure 4G), our data suggest that the downregulation of LYN, FYN kinases and the NFκB signaling could explain the reduced OX40L expression in NSCLC-TECs.
