In the high expressing human lung adenocarcinoma H2126 cell-line, the complete promoter with exon 2 and intron 2 construct (CP-E2I2-Luc, p = 0.003) and the promoter alone construct (CP-Luc, p = 0.006), were able to significantly increase luciferase expression compared to pGL3 Basic (data not shown). Here, CP is linked to lung adenocarcinoma.
