Relative expression of SNHG6 in ESCC tissues. (A) RT-qPCR was used to detect the relative expression of SNHG6 in ESCC tissues and adjacent normal tissues (n=70). The results were normalized to GAPDH expression and presented as ΔCq. (B) Relative SNHG6 expression in ESCC tissues and adjacent normal tissues (n=70). A fold-change ≥1 represents high expression of SNHG6, while a fold-change <1 indicates low expression of SNHG6 in ESCC tissues. (C) Relative SNHG6 expression in 2 ESCC cell lines (ECA-109 and TE-1) and 1 normal esophageal epithelium cell line (HEEC). (D) RT-qPCR was used to assess the expression of SNHG6 in ECA-109 and TE-1 cell lines transfected with different si-SNHG6 sequences. **P<0.01 with comparisons shown by lines. RT-qPCR, reverse transcriptase-quantitative polymerase chain reaction; ESCC, esophageal squamous cell carcinoma; si-SNHG6, small interfering RNA targeting small nucleolar host gene 6; Cq, quantification cycle; NC, negative control.
