The TNFRSF19 expression was significantly lower in lung cancer tissues than in the para-cancer tissues (Fig. 7a), in agreement with the data from the TCGA [30, 31], Oncomine [32], and GEPIA [33] databases (Fig. 7b, c; Additional file 1: Figure S6a & b). This evidence concerns the gene TNFRSF19 and lung carcinoma.
