Colony assay and the impact of combination therapy on colony formation ability of A549 cells. (A) Reduction of lncRNA-DLGAP1-AS2 expression and treatment with carboplatin can reduce colony formation of A549 cells. (B) Results from qRT-PCR revealed a significant reduction in CD44 mRNA expression in the treatment groups, especially in the combination group (**P < 0.01, ***P < 0.001, ****P < 0.0001).
