Knockdown and overexpression of PlGF by lentivirus infection. a, b H1975 (a) and H358 cells (b) are infected with shNC, shPlGF-1, shPlGF-2, or shPlGF-3 to knock down PlGF. c PlGF is overexpressed in PC9 cells transfected with oePlGF. mRNA and protein of PlGF are examined, respectively. *p < 0.05, **p < 0.01, ***p < 0.001 vs. shNC or Vector
