Fig. 1. CCDC144NL-AS1 is upregulated in GC and associated with poor prognosis.
a Heat map analysis of CCDC144NL-AS1 expression in GC from the TCGA database. b, c Relative expression of CCDC144NL-AS1 in unpaired and paired GC tissues was analyzed from the TCGA database. d qRT-PCR was used to detect the expression of CCDC144NL-AS1 in 72 GC tissues and paired adjacent normal tissues. e qRT-PCR analysis of CCDC144NL-AS1 expression in GC cells and normal gastric epithelium cell line (GES-1). f Online Kaplan–Meier overall survival (OS) curves according to CCDC144NL-AS1 expression levels. *p < 0.05, **p < 0.01, ***p < 0.001.
