DPP10 and lung carcinoma: To further confirm the effect of DPP10-AS1 on lung tumor growth in vivo, we screened 2 lung cancer cell lines (SPC-A1 and NCI-H1299) stably expressing DPP10-AS1 by using geneticin (G418) and subcutaneously injected them into nude mice to establish a xenograft tumor model (Figure 2I).
