Knockdown of KLRG1 in A549 and H1299 lung tumor cells. A-B The KLRG1 knockdown efficiency in A549 was evaluated by qRT-PCR, n = 3 for each group (A) and Western blot (B). C-D The KLRG1 knockdown efficiency in H1299 was evaluated by qRT-PCR, n = 3 for each group (C) and Western blot (D). The full-length gels are presented in Supplementary Figure 1 and Figure 2. E-F The effect of KLRG1-knockdown on the proliferation of A549 (E) and H1299 (F) tumor cells, n = 4 for each group. P values are derived from two-tailed unpaired Student’s t-test. Data represent mean ± SD. **, P < 0.01, ***, P < 0.001, ns, no significance
