The expression and characteristics of circATXN7 in GC. a The expression of circATXN7 in GC tissues and matched non-tumor tissues was detected by qRT-PCR. b The expression of circATXN7 in GC cell lines (MGC-803, SGC-7901, MKN-45, AGS, BGC-823) and one gastric epithelial cell line (GES-1) was detected. c The genomic loci of the ATXN7 gene and circATXN7. d Agarose gel electrophoresis was utilized to confirm circATXN7 specificity and accuracy in qRT-PCR products from MGC-803 and AGS cells. e qRT-PCR analysis was applied to assess the expression circATXN7 and ATXN7 RNA after treatment with Actinomycin D. f qRT-PCR analysis was applied to assess the expression of circATXN7 and ATXN7 RNA after treatment with RNase R. g The potential diagnostic value of circATXN7 was evaluated. **P < 0.01
