The profiling of the differential miRNA expression in the IVDD patients compared with the control group and in TNF-α-treated and untreated NP cells. (a). A total of 27 miRNAs were differentially expressed in IVDD tissues and in normal tissues (n = 5 for each group). (b) A total of 27 miRNAs were differentially expressed in TNF-α-treated and untreated human NP cells for 6 h at 20 ng/mL (n = 3 for each group). Green: low expression; red: high expression. (c) The expression of miR-502 was detected in normal and IVDD tissues by qRCR. (d) The MiR-502 expression was measured in the NP cells with and without 20 ng/mL TNF-α by qRCR. ∗∗P < 0.01 and ∗∗∗P < 0.001.
