NNT-AS1 is up-regulated in DDP-resistant CC tissues and cells lines and highly expressed NNT-AS1 predicates poor prognosis. a NNT-AS1 expression was detected using qRT-PCR in normal tissues and DDP-sensitive or DDP-resistant CC tissues. b The role of NNT-AS1 in the CC prognosis was analyzed by Kaplan–Meier method. c NNT-AS1 level in HaCaT cells and DDP-sensitive or DDP-resistant cell lines was analyzed by qRT-PCR. *P < 0.05
