The expression of circ-ADAM9 in DR patients and HG-induced ARPE-19 cells. (a) The circ-ADAM9 expression in the serum of DR patients and normal control volunteers was detected by qRT-PCR. (b) QRT-PCR was used to measure circ-ADAM9 expression in ARPE-19 cells under HG and NG conditions. (c) Subcellular localization analysis was used to detect circ-ADAM9 expression in the cytoplasm and nuclear. (d) RNase R assay was performed to assess the circular characteristics of circ-ADAM9. ∗∗∗P < 0.001 and ∗∗∗∗P < 0.0001.
