Aberrant expression of KDELR1, KDELR2, and KDELR3 in LUAD patients. (A–C) Relative mRNA expression levels of KDELR1 (A), KDELR2 (B), and KDELR3 (C) in LUAD tissues compared to normal tissues. (D–F) Expression of KDELR1 (D), KDELR2 (E), and KDELR3 (F) in 57 pairs of LUAD and adjacent tissues from TCGA. (G–I) qRT-PCR validation of KDELR1 (G), KDELR2 (H), and KDELR3 (I) expression in 23 pairs of clinical LUAD and adjacent tissues. (J–L) Expression of KDELR1 (J), KDELR2 (K), and KDELR3 (L) in 20 pairs of LUAD and adjacent tissues from GSE33532. (M–O) Representative immunohistochemical staining of KDELR1 (M), KDELR2 (N), and KDELR3 (O) in LUAD tissues and normal lung tissues. (P, Q) Protein expression levels of KDELR1 (P) and KDELR3 (Q) in LUAD, and normal lung tissues. (*p < 0.05, **p < 0.01 and ***p < 0.001).
