Expression of hsa_circ_0004771 (also called circ_NRIP1) in esophageal squamous cell carcinoma (ESCC) tissues and cells. a RT-qPCR detect circ_NRIP1 expression level in 42 paired tumor tissues (Tumor) and adjacent normal tissues (Normal) from ESCC patients. b RT-qPCR detect circ_NRIP1 expression level in human ESCC KYSE30 and KYSE450 cells, as well as normal HET-1A cells. c, d RT-qPCR detect RNA levels of circ_NRIP1 and its host gene NRIP1 in KYSE30 and KYSE450 cells subjected to RNase R, compared to cells mock cells (without RNase R treatment). *P < 0.05
