GSTP1 and adenocarcinoma: In vivo analysis using nude mice and tail vein injection of luciferase‐labeled A549 GSTP1‐OE or control (EV) cells showed, by the 10th week post‐injection, 5/6 mice in the GSTP1‐OE group developed bioluminescent lung nodules which were histologically confirmed to be adenocarcinomas (Figure 2C,D), while 0/6 control mice developed tumors, respectively.
