SNHG7 is up-regulated in ESCC tissues and cell lines. (A) qRT-PCR was used to detect the expression levels of SNHG7 ESCC tumor tissues and normal tissues; (B) qRT-PCR was used to measure the levels of SNHG7 in HET1A cells and ESCC cell lines (TE1, EC109, TE13, and YES2). *P<0.05. SNHG7, small nucleolar RNA host gene 7; ESCC, esophageal squamous cell carcinoma; qRT-PCR, quantitative real-time polymerase chain reaction.
