TP53TG1 and non-small cell lung carcinoma: To further investigate the function of TP53TG1 on cisplatin sensitivity of NSCLC, we manipulated TP53TG1 expression by transfecting TP53TG1 overexpression plasmid (pcDNA-TP53TG1) into A549/DDP cells and introducing two individual TP53TG1 siRNAs (si-TP53TG1#1 and si-TP53TG1#2) into A549 cells.
